Supplemental Foods

We recommend eating these “supplemental foods” on a regular schedule:

  • 3 egg yolks daily, 5 yolks daily for women who are pregnant or planning to become pregnant (for choline, folate, vitamin A)
  • A bowl of soup made from bone, joint, tendon, foot, or hoof stock, 3 days per week (for calcium, phosphorus, and collagen)
  • Fermented vegetables such as kimchi, sauerkraut, or fermented mixed vegetables (for nucleotides, probiotic bacteria, and vitamins K2 and B12), and other vegetables such as tomato, avocado, potato, sweet potato, banana, green leafy vegetables, and seaweeds such as dulse, daily (for potassium)
  • ¼ lb beef or lamb liver, weekly (copper, vitamin A, folate, choline). If you like, substitute ¼ lb chicken, duck, or goose liver weekly plus 30 g 85% dark chocolate daily
  • fish, shellfish, eggs, and kidneys, weekly (for selenium)

Daily Supplements

These are supplements we recommend be taken daily:

  • Sunshine and vitamin D3 as needed to achieve serum 25OHD of 40 ng/ml.
  • Vitamin K2 100 mcg or more
  • Magnesium 200 mg
  • Iodine 225 mcg
  • Vitamin C 1 g
  • Pantothenic acid (vitamin B-5) 500 mg
Vitamin D3
  • Seek total dose from sun, food, and supplements of 4,000 IU/day
  • Adjust to 25OHD level of 40 ng/ml (whites/Asians), 30 ng/ml (blacks)
Vitamin K2
  • Recommended dose: 100 mcg MK-7

  • Powder is least expensive way to get large doses
Vitamin B-5 (pantothenic acid or pantethine)
  • 500 mg per day; we suggest daily due to its extreme safety
  • Acne/skin blemishes or low energy/endurance are symptoms of deficiency

Weekly Supplements

These are supplements we recommend be taken once a week:

  • B vitamins:
    • 50 to 100 mg each of B1, B2, and B6
    • 5 mg biotin

B12
  • We recommend 500 mcg to 1 mg once per week
  • Sublingual methylcobalamin is preferred
Zinc
  • We recommend about 50 mg per week
  • Be sure to follow our copper recommendations as copper-zinc balance is crucial
Boron
  • The 3 mg dose can be taken one to three times per week

Prenatal Supplements

The most important prenatal supplements are:

  • Extra duck, goose, or pastured chicken liver.
  • Extra egg yolks.

The following supplements may also be helpful during pregnancy or in the months leading up to conception. Note: We do not recommend prenatal multivitamins.

Choline
  • Not necessary if you eat enough egg yolks and liver
  • But extremely important during pregnancy, and safe
Inositol plus Choline
  • Not necessary if you eat enough egg yolks and liver
  • If supplementing choline, good to mix in some inositol
Iron (optional)
  • About 30% of pregnant women develop iron deficiency anemia
  • Don’t guess, test; blood tests will indicate if you need iron supplements

Optional Supplements


These supplements may be helpful for a significant fraction of the population. Experiment to see if they help you:

  • Probiotics
  • Chromium, 200-400 mcg per week (not necessary if you cook in stainless steel pots) and (optional) vanadium, 25 mcg per week
  • Lithium 5 to 10 mg per week
  • Silicon 5 mg to 25 mg daily
  • FOR PEOPLE WHO DO NOT EAT LIVER: Copper 2 mg per day
  • FOR PEOPLE WHO DO NOT EAT LIVER: Vitamin A from cod liver oil, 50,000 IU/week
  • FOR PEOPLE WHO DO NOT EAT MAKE BONE STOCK OR DRINK MINERAL WATER: Calcium up to 400 mg/day
  • B-50 complex (as a substitute for individual B supplements if you prefer fewer pills
  • Molybdenum 150 mcg per week
  • Taurine 500 mg to 5000 mg per week (higher doses may be therapeutic for small intestinal or systemic infections)
  • Selenium 0 or 200 mcg per week depending on selenium content of food (if food is produced in dry, flat areas = high selenium, no supplements; rainy, well-drained areas = 200 mcg/wk)
Probiotics
  • Bifidobacterium spp can help with leanness and weight loss.
  • Lactobacillus spp can help with acid reflux, bloating, SIBO, prediabetes, high triglycerides
More Probiotics
  • Bifidobacterium spp can help with leanness and weight loss.
  • Lactobacillus spp can help with small intestinal issues
More Probiotics
  • VSL#3 is a good mix for inflammatory bowel diseases.
  • Prescript Assist includes soil-based organisms that are a little riskier and should be taken only occasionally, not continuously, for therapeutic reasons.
Chromium
  • If you don’t cook in stainless steel, we recommend 200 mcg chromium one to three times per week
  • Stainless steel pots may release 88 mcg chromium per day of use
  • Optional: vanadium 25 mcg one to two times per week
Lithium
  • Best is to take 1 mg per day; 5 mg once or twice per week is next best
  • Caution: too much lithium can exacerbate hypothyroidism and increase potassium excretion
Silicon
  • Up to 25 mg per day
  • Most people would benefit from more silicon
  • Seaweed is a good food source
Copper (Only If Liver Is Not Eaten)
  • Target of 2-3 mg/day can be met by eating 1/4 lb beef or lamb liver per week

Calcium (If No Mineral Water or Bone Stock)
  • PHD foods may fall short of calcium target by up to 400 mg/day
  • Standard PHD prescription is to make up the difference with bone stock and/or mineral water
  • These supplements also replace magnesium supplement; aim for 300-500 mg calcium and 150-250 mg magnesium per day
B-50 complex
  • An alternative to the other B vitamins for those who prefer to take fewer pills
  • Not recommended more than once per week due to folic acid and niacin content
Molybdenum
  • We recommend 150 mcg to 1 mg per week
Taurine
  • We recommend 500 to 1000 mg weekly for healthy persons
  • Supports production of bile salts
Vitamin E

    What’s the suggested amounts/frequency for fermented foods?

      Dear Abi, if you do not have SIBO (Small intestinal Bacteria Growth) then you can eat fermented foods to appetite. Listen to your body and it will tell you when it is enough.

    I have a question about iodine supplements. I can’t take potassium iodine because of another medication I am on that I can’t take potassium with. So I’ve been taking organic kelp in pill form, 225mcg a day. But on a recent trip to Florida, I ate lots of shrimp, crab and other seafood (while still supplementing the kelp) and I ended up getting hives from overdosing on iodine (runs in my family). I was hoping supplementing iodine throughout the year would prevent this from happening to me. Do you recommend I continue to supplement or should I stop? Thanks!

      Dear Gabby, on days you consume a lot of seafood you should skip on kelp. if you like seaweed you should eat only small amounts of it. Otherwise, you may be hurting your thyroid. Hope it helps.

    Hi Paul,
    I have been doing PHD for about 2 1/2 years. I was a early 50s guy becoming limited physically due to inflammation. Now my health is better in so many ways, and I feel more like I did in my 20 and 30s.
    My blood test results recently had mostly good numbers but blood platelets were 143 the suggested good range was 150 to 450. I do bruise easily sometimes.
    Do you have any suggestions for upping platelets?
    Also is it OK to take a large dose of vitamin D once a week or better to spread it out over the week? Thanks.

    Do you have particular recommendations for supplements to take and ones to avoid for someone who is on chemotherapy for breast cancer? My best friend just started chemo. Both she and I follow PHD but we were wondering if the supplements you recommend should be taken while she is on a six-month course of chemotherapy. Thank you.

    I have seen a study which correlates choline supplementation to higher levels of TMAO and blood clotting. They suggest that choline-rich foods, like eggs would have the same effect. What is your opinion?

    Hi Paul,

    I am a bit confused about the logic behind the suggested dose for supplemental B12.

    Since PHD suggests animal foods with every meal, I assume that healthy individuals would have no trouble obtaining sufficient B12 from food on PHD. (Certainly, blood tests indicate that I have no trouble obtaining sufficient B12 from food.) Most of the benefit of supplemention would thus be seen in the nontrivial fraction of people (several percent) with B12 malabsorption.

    So how much B12 is needed in cases of malabsorption? The following is taken mostly from [1]:

    One common cause of B12 malabsorption is pernicious anemia, in which active transport (about 50% efficiency) is impaired, and B12 can only be absorbed via passive diffusion. From experiments with radiolabeled B12, passive diffusion has about 1% efficiency on average — but individual variation is significant and absorption rates around 0.5% are not rare. Note that these figures for passive diffusion assume supplemental B12 is taken while fasted; if supplemental B12 is taken with food, absorption rates via passive diffusion are about 30% lower.

    This has two effects:

    * B12 absorption declines by a factor of 50 on average, but sometimes by as much as 100.

    * The requirement for absorbed B12 is roughly doubled, since B12 loss during enterohepatic circulation jumps from roughly 50% to roughly 99%.

    So in theory, requirements for dietary B12 in pernicious anemia are raised by roughly a factor of 100 on average, but sometimes by as much as 200. This suggests doses of 100 x RDA ~ 250 mcg/day ~ 2 mg/wk would be necessary for the average person with pernicious anemia; doses as high as 500 mcg/day ~ 4 mg/wk would be necessary for some such people; and it looks probable that 5 mg/wk is high enough to ensure adequate B12 status in all cases of B12 malabsorption. (At least if taken on an empty stomach — if taken with a meal, a bit more, perhaps 7 mg/wk, would be needed.)

    Note that such doses are readily available in the form you recommend (sublingual methylcobalamin):

    https://www.amazon.com/Jarrow-Formulas-Methylcobalamin-Supports-Lozenges/dp/B0013OQGO6/ref=sr_1_3?crid=21NBUGKHWSY10&keywords=methylcobalamin+b12+5000+mcg&qid=1554700268&s=gateway&sprefix=methylcobalamin%2Caps%2C215&sr=8-3

    In practice, to quote [1]:

    “…Heinrich… discusses the suitable daily maintenance dose and finds 300 mcg daily to be adequate. Statistically this is correct, because this dose results in an absorbed and retained average quantity of approx 3 mcg, or slightly more than the normal daily turnover. However, considering the variations in absorption, a wider safety margin seems to be appropriate… Heinrich’s figures, as well as ours, show some absorption values far below average, and in our experience low values are found rather constantly in certain individuals. Heinrich refers to clinical trials, published by others, indicating that 300 mcg daily might be sufficient. Our more comprehensive material, followed up for a much longer period of time, showed that 500 mcg daily, although in general adequate, may give borderline serum B12 values in a few cases. In these patients normal values were rapidly restored by 1000 mcg daily.”

    How would these doses effect healthy individuals?

    Milligram doses of B12 are far above the saturation point for active transport, which typically is about 2 or 3 micrograms — so only roughly 1% of the dose (on average) would be absorbed, i.e. about 10 mcg for 1 mg/wk, or 50 mcg for 5 mg/wk. For comparison, typical absorption of B12 from food on PHD would presumably be almost 20 mcg/wk (two meals per day that saturate active transport). And if suggestions on intermittent fasting were disregarded, and B12-rich foods like liver were spaced out carefully over the enlarged feeding window to maximize B12 absorption, you could probably absorb almost 40 mcg/wk from food alone.

    So a single dose of 5 mg/wk would result in more B12 absorption than one could get from food… but not by that much! (And the suggested dose of 1 mg/wk would result in significantly less B12 absorption than a healthy person would get from food.)

    Now, most of these studies are with oral cyanocobalamin, rather than sublingual methylcobalamin. However, sublingual B12 does not appear to be significantly more bioavailable than oral B12: [2] suggests no significant difference in absorption between oral and sublingual cyanocobalamin, and [3] suggests no significant difference between oral and sublingual methylcobalamin. Unfortunately, I could not find any studies directly comparing the bioavailability of methylcobalamin to cyanocobalamin in the regime where absorption is dominated by passive diffusion. If there is a difference in bioavailability in this regime, my guess would be that methylcobalamin would be less bioavailable, on account of its significantly higher number of rotatable bonds [4, 5, 6]. But methylcobalamin appears to work as a treatment for pernicious anemia at doses similar to cyanocobalamin, at least in a couple of patients [7], so I presume the difference in bioavailbility cannot be too large.

    Am I missing something here?

    Best,
    -Eric

      Hi Eric,

      Thanks for this analysis. I don’t think you’re missing anything in terms of understanding the papers … but if you assume a bit of uncertainty in all of the numbers, then it may be easier to understand the rationale. The idea is essentially that B12 is very safe so any excess is not harmful, while deficiencies can be a problem. If there were certainty that absorption from food was 50% while absorption from a supplement was 1%, then yes, you’d conclude that we should just get it from food and not worry about supplementing. But if you factor in a possibility of poorer absorption from food or better absorption from supplements, coupled with a risk from deficiency but no risk from excess, then it will make sense to supplement occasionally (once a week or once every two weeks).

      Best, Paul

        Hi Paul,

        My interpretation of these papers was that a supplemental dose of 1 mg/wk would be insufficient for most people with B12 malabsorption.

        On the other hand, a dose of 5 mg/wk would be sufficient for almost everyone with B12 malabsorption — and harmless for healthy individuals.

        So why recommend 1 mg/wk rather than 5 mg/wk? (The same company whose 1 mg tablet you suggest also makes a 5 mg tablet.)

          Any views on B12 5mg per week, versus 1mg 5 days per week. Would one give a better result over the other ?

            Hi Darrin,

            For the reasons Paul discusses in his section about B vitamin supplementation (the box titled “Why Weekly Supplementation May Be Best”), I would lean towards 5 mg per week as an insurance policy. Higher doses more infrequently (e.g. monthly supplementation) may not be retained well.

            An alternative insurance policy is periodic lab testing. Vitamin B12 deficiency will raise methylmalonic acid levels in urine and blood; this is the most sensitive indicator. In more severe deficiencies, serum B12 will fall. If these lab tests look normal (especially if methylmalonic acid is in the bottom half of the reference range and serum B12 is in the top half), it seems safe to assume that supplementation would offer no benefit.

            Best,
            -Eric

    Hey Paul,
    What do you think about Liposomal C & Glutathione? Any better absorption than acorbic acid crystals or NAC or just expensive hype & a waste of money?

    Also, I’ve tried 3 different Creatine Monohydrate supplements because I know it’s one you recommend. Jarrow Creapure, Now Creatine Monohydrate Powder that you link to, & lastly Now Are-Alkylyn & all came with awful side effects for me. I noticed the benefits with the 2 powders at the gym- could lift heavier & for longer without it feeling more difficult & could see my muscles more, but I experienced headaches, bloating, Palpations, Insomnia & frequent urination with just the 5 grams a day- I even tried 2.5 grams & still had the side effects so had to quit despite the benefits I enjoyed. Then with Kre-Alkyln (buffered creatine monohydrate) I did not experience the benefits as I did with the regular CM, & I had side effects of difficulty breathing/anxiety so I quit taking it after about a week. What do you think could be happening? My husband quit the powder also because of GI/stomach distress. Is there a secret to taking it or is it common for some people to be intolerant to supplementation with it? I’m really bummed because the classic powder did give a boost at the gym.

    Thanks Paul!

    Hi there,

    I had a quick question about your Vitamin A suggestions – I’ve heard overdosing can be unhealthy so I’m keen to get it right.

    I don’t (and probably won’t) eat liver, so thought I’d better supplement some. My daily multivitamin contains 2500IU mixed beta-carotene and acetate (so quite low). I also usually eat 2 eggs most days, probably 5 days a week, and a can of sardines maybe 2 times a week.

    So my question is, is there a ballpark amount of additional vitamin A supplementation you’d recommend?

    Lastly, does the form make a great difference in terms of bioavailability? For example I can purchase retinol acetate tablets very affordably (much cheaper than good cod liver oil), just wondered if these are best avoided or should do fine.

    Thank you for any help you can give me, and for the wonderful diet advice in your book, which has been a great help to me.

    I am wondering if there are any of these recommended supplements I should not take due to the fact that I have half my thyroid (partial removed because of tumor, not cancerous) and also I am on Lisinopril for blood pressure. I have heard blood pressure meds and thyroid meds don’t mix well with supplements.

    Dear Paul,
    Are there any deficiencies which can cause insomnia or prevent melatonin production?
    Thanks.

    • Paul Jaminet August 7, 2019 at 8:24 am

      Hi John,

      Deficiencies in ability to produce energy can cause insomnia. Some nutrients which can support that include magnesium, vinegar (acetate), citric acid (citrus fruits) and malic acid (apples) (to provide TCA cycle intermediates citrate and malate). Electrolyte deficiencies (especially potassium) or dehydration are also common causes of insomnia.

      Inflammation and circadian rhythm disruption are the most common causes of insomnia. Nutrients that support immune function to reduce inflammation include vitamin A, vitamin D, vitamin C, N-acetylcysteine, glycine, zinc, copper, iodine. Stopping eating in the afternoon, light exposure plus exercise plus food in the morning, no blue or green light at night, are good steps for circadian rhythm entrainment.

    I am currently living in Germany and can’t seem to find Vitamin A from cod liver oil. The only form I can find is beta-carotene. We aren’t liver eaters, so we were supplementing copper and vitamin A. Is beta-carotene a good substitute? From what I can find on the site it doesn’t seem to be but I’m not sure why (and I didn’t see anything in my book). Would cod liver be a better substitute or should we just forgo vitamin a supplementation? Any other ideas? Right now we just aren’t taking vitamin a or copper.

      Raw, but anyway the raw weight and the cooked weight should be about the same if you cook it gently just as the book explains, i.e. cooking with moist / cooking without dehydrating the food

        …Although I’m not really sure about what I just said, so I’ll correct it: with potato foods it’s true that the raw weight and the cooked weight are the same, but meats tend to release juices especially if salt is added during cooking, so even if cooked gently they will weight less when cooked. So in conclusion, for liver, use the raw weight as a reference

    Hi Paul,

    What recommendations do you have for tooth health? I follow all guidelines established such as brushing teeth twice a day and flossing, yet I cannot avoid the occurrence of caries. I also take Vitamin D 8000IU a day. Please let me know your thoughts.

      Vitamin K2 is most important, magnesium also helps, also an extracellular matrix rich diet. Eating a balanced natural whole foods diet along the lines of PHD, without added sugar, is important. Eat sources of vitamin A such as carrots, eggs, liver. Circadian rhythm entrainment.

      Hi Alex. I am not a health professional – just saying however I read somewhere that a mum of 13 children found the dentist bills a bit much and she took her children off whole grain products and what do you know…zero tooth decay! Not sure of the connection but thought I would mention it to you.

    Hi Paul,

    I don’t understand the recommendation to supplement 50,000 IU/week of Vitamin A for those who don’t eat 1/4 lb of liver per week. Isn’t there almost as much Vitamin A in a whole pound of beef liver?

    I find Vitamin A to be intimidating, especially after reading journal articles about liver damage from only 20,000 IU/day. Is there a good way to test for deficiency?

    Thanks.

    I would like to chime in that I cannot understand the vitamin B5 recommendation of 500 mg. When I first began taking 50 mg daily, I slept extremely well for a few nights. Then I had terrible insomnia. I can take 50 mg now about once or twice a week and have great sleep that night. Anymore and the insomnia is back. So I am shocked at the recommendation of 500 mg per day.

    Hello Paul,
    You helped me a about a year ago on hear & I wanted to give you an update. Since reducing the iodine to your recommended 225mcg & reducing supplemental selenium, I believe my health has improved- I have lost 7 pounds & weight is consistent, & my TSH went down to .93 & I know you say under 1 is good. Thank you for helping.

    I have a question now about copper- I’ve read copper toxicity can cause cancer. Do you think copper pipes/plumbing in the home is a problem? I only drink filtered/distilled water so we’re not drinking from the tap & we shower instead of soaking in a bath. We follow the PHD supplements & diet, except we don’t supplement copper, but eat liver occasionally.

    Thanks again!
    Holly

      Dear Holly, thanks for the update! Glad to hear you are well – although we do think TSH of 1.5 is better than 0.93, which could be suggestive of a nodule in your thyroid that is over-producing thyroid hormone.

      Copper toxicity can be a problem but so can copper deficiency. Be sure you are getting adequate zinc as that will help limit copper toxicity. The National Research Council wrote a book on the subject of risks of leaching from copper pipes, see https://www.ncbi.nlm.nih.gov/books/NBK225408/, which was the basis for the EPA’s guidelines. I am not aware of evidence that would provide a basis on which to disagree with the current EPA guidelines for drinking water.

        Hello Paul, thank you so much for your reply! A year ago, my TSH was .80, so it went up to .93 in a year with a Free T4 of .89. Back in 2016, my TSH was 181 & that was when I was on high dose iodine (aproximately 10-12mg daily plus 200mcg daily selenium from about 2012-a year ago) Is there anything I can do about the nodule to correct this overproduction of thyroid hormone? Of course my Dr says “results are normal”, I strive for optimal. What can I do to get closer to a TSH of 1.5 & further improve my thyroid status?

        As long as we have copper pipes for our indoor plumbing at home would it be a good idea to take our 50mg zinc supplement daily rather than weekly? Further, is the risk great enough that you would consider the expense of changing your copper pipes to PVC?

        Thanks again!

          Hi Holly,

          Sounds like you are doing the right things re your thyroid. High dose iodine often leads to thyroid injury which caused your hypothyroidism and then some hyperthyroid nodules. It seems you are healing. Time and good nutrition and good circadian rhythm entrainment are the keys. Extracellular matrix and vitamin C are valuable nutrients. Time will heal this entirely.

          50 mg zinc every day is too much. You can do up to 4 days per week.

            Hello Paul,

            Thank you for the research article on copper pipes- sounds like nothing to worry about at all.

            Would you please give your opinion on the reliability of hair analysis? I recenttly sent a sample in & it came back I have low copper- so it looks like I need to be following your recommendations for daily 2mg copper supplement since I haven’t been eating liver regularly, (& I don’t do well on dark chocolate & nuts) & back off the zinc to the recommended 50mg once or twice per week, rather than several times per week.

            Also, the results said I have a manganese deficiency & I reviewed what you say in my PHD book on manganese & that you don’t recommend supplementing it. I don’t do well with eating nuts or shellfish & the hair analysis nutrition counselor is suggesting I take a manganese supplement- 30mg a day. I think that is an extremely high dose & don’t feel comfortable with that based on what you say. If I took any, it would be half a 10-15mg tablet a day max. Would you still advise against it or is there an exception in this situation?

            Been meaning to tell you I had started having a lot of chronic muscle/joint pain a while back & what seemed like gym injuries that wouldn’t heal & I decided to look back over your supplement list to see if I was missing something, & I saw Silica under optional & reliazed I’d quit taking it 2-3 years ago since it was optional, to save a buck. I decided to give it a try again & it reduced my pains by about 90-95% & it didn’t take long. I’m amazed!

            Thank you so much!

            Hey Paul,

            I’ve figured it out. You’re clear in your book to not take manganese in supplement form, so I will not do it. I will just try to eat some hazelnuts, macadamia nuts & pecans like you said. My guess is I fell for some pseudoscience claims again like I do occasionally with the hair analysis, but fortunately I didn’t buy any of their supplements they recommended based on it. I’m sticking with your solid, conservative supplement recommendations. From trial & error, I’ve found that’s best.

            Thanks!

          Hello Holly,

          We have copper pipes too and we even drink from the tap. Given your usage, I don’t see any reason for you to be worrying so much. Surely you’re not going to absorb much at all from it running over your hands/body.

          As for our tap consumption, our water is not chlorinated and we are very careful to sufficiently run the water before collecting it into a glass bottle. We also don’t collect any in the morning or after being away for some hours until after we have flushed the toilet since this evacuates the water that has been sitting in the pipes (and our water is unfortunately extremely soft so acidic! the harder your water, the less you need to even worry).

    I’m suffering from hyperthyroidism. I take one methimazole 6 times a week. I will follow your daily and weekly prescriptions. However, I will exclude Iodine. And I’m going to take in extra selenium. Do you have any other advice for me?

      Hi,

      Yes, to promote wound healing generally, it’s helpfully to eat more extracellular matrix — bones/joints/tendons cooked in soups and stews, and shellfish — with extra vitamin C, plus optimization of zinc, copper, and glutathione per the book. For glutathione, a reasonable approach is 1 g taurine taken in the morning and 1 g glycine taken in the evening. Circadian rhythm entrainment is always important for healing as well.

    I bought vitamin D. amount per serving is 250mcg(10000iu)

    I’m worried that it is excessive if I take this 1 softgel every 3 days.

    You recommended 40ng and 40ng is 0.04mcg. isn’t it??? 250mcg is so large than you recommendations.

    I can’t understand meaning of 40ng/mg.

    I have 250mcg(10000IU)
    How can I do??

      Hi, you can take that twice a week in winter or once a week in spring and fall. Vitamin D stays in the body for weeks and it is not necessary to take a consistent dose every day.

    Hi Paul, thank you for all your amazing work! My girlfriend has ME/CFS and I’m loving your book as it gives me/her hope!!

    We’ve implemented the macros, and now working on implementing the vitamins, however I’m getting stuck on something:

    Does it matter what the vitamin pill casings are?

    I’m seeing pullulan (which when googled says that it could mutate into cancer), cellulose, hypromellose, and the addition of a rice extract blend (which is organic but sadly contains sunflower oil).

    I assume best bet is to get powdered where possible, but what about when pill form is required?

    Any any all thoughts are much appreciated, thank you!!

    Specifically, I’m looking at this for Magnesium, but am worried about the hypromellose and the added sunflower oil used in the flow agent: https://www.amazon.co.uk/Bisglycinate-Bioavailable-Love-Life-Supplements/dp/B01GVLNUO4/ref=cm_cr_arp_d_product_top?ie=UTF8#HLCXComparisonWidget_feature_div

    Hi Paul, thank you for all the research you’ve done here, it’s amazing!!

    A question on Zinc: is there a reason you specifically say 50mg per week instead of 7mg per day?

    Since you specify in the book that 40mg per day is postively dangerous, wouldn’t it be safer if I took 7mg per day instead?

    Thanks!

    Hello everyone, I hope that the Jaminets will update this soon. Bone broth contains very little calcium. Hence Dr. Kaayla Daniel says that you should not drink bone broth for its calcium, but for other benefits.

    Hey Paul,

    I’m rereading your book & discovered in the chapter on alcohol that including nutrients such as methionine, vit C etc can be helpful in insuring protective measures while consuming. I do enjoy a daily evening cocktail made of 1-2 ounces of high quality liquor.

    My question is would it be beneficial to supplement L-Methionine, or do we get enough of it in our diet from meat?

    Thank you!
