  1. I question the bodies ability to absorb B-12 and D through supplements. So much information out their claiming that vitamins could be too old, or ineffective, or completely un absorbable. Which supplements do you recommend?

  2. Are not all vitamin D3 supplements derived from sheeps wool (Lanolin), and also cholacalciferol is used widely as a rodenticide (like sodium fluoride) do we want to be ingesting something like this ?

  3. There is a vegan D3 by Vitashine. I know one person whom it worked for with raised levels, and one person (Victor Van Epps) for whom it didn't seem to.

  4. Dr. Michael Greger (2:29): "We likely used to get all the vitamin B12 we needed drinking out of mountain streams, or well water, but now we chlorinate our water supply to kill off any bacteria, so we don't get a lot of B12 in our water anymore."

    — The hypothesis that humans could have got in the past all the vitamin B12 they needed from non-sanitized water is inconsistent with empirical knowledge about it.
    For this to be accurate, you would need a lot of vitamin B12-producing bateria to get enough vitamin B12. There just isn't enough fecal matter even in the most polluted waters to supply daily requirements. Take into account that some animals like rabbits need to eat several grams a day of their own feces (largely composed of vitamin B12-producing bacteria) to get enough vitamin B12, and rabbits are much smaller than humans.

  5. Cultures long ago unintentionally ate quite a bit of their food contaminated by small insects and droppings from birds, rodents, spiders, and insects and also insect and spider eggs. An unsanitized world without refrigeration, so unlike what we have today in the developed world, would have supplied people with a good deal of B12, and if they supplemented their diet with any animal products or other insects, they would have had plenty. In addition, unfiltered drinking water from streams would have contained tiny organisms that would have been ingested.

  6. I read an article once about some vegans from India who moved to the UK and became deficient in B12. Apparently in India people get their B12 from bathing in less than pristine water sources like the Ganges river. So when they moved to the UK and had clean water; they weren't being exposed to the B12 bacteria.

  7. Dr Gregor. Thanks for all you do. Can you please expand on D3 vs. D2. There are conflicting conclusions and I would appreciate your take. Best.

  8. My theory is that we received our B12 from grooming each other. Simians of all types spend many hours each day picking dead skin, lice, fleas and ticks off each other and eating what they find. All that material is filled with bacteria and most importantly bacteria that has a mutualistic relationship with the host. Even today, we all have bacteria within our guts and on the surface of our bodies. The majority of those bacteria are benign and provide us with most of our vitamin K and compete with the other alien bacteria that would invade our bodies and do us harm.

  9. German sauerkraut contains the vitamin B12 but it is not available all year around. It should be consumed fresh by taking it from the little wooden barrel where it is fermented in. I don't agree with people saying that it contains too much salt. Every sauerkraut seller has their own recipe and add more or less salt as they like.
    One important thing is that it shouldn't be pasteurized.

  10. Do you approve or deny
    the efficacy and/or safety of daily supplements such as: Glucosamine, Chondroitin, MSM (vegan version of course). I have been taking these but am skeptical if I should continue.

  11. i can't with your voice, sorry doc, u sound like u smoked a blunt and slowly reading your notes.. 😩

  12. In your other video you say that multivitamins are ineffective. If supplements for vitamin d or b3 are effective then why wouldn't multivitamins have the same effect since they generally contain both.

  13. Dr. Greger deserves a Nobel Peace Prize for all his work more than anyone right now. You sir are a paradigm shifter! Thank you for the thousands of videos you have organized and presented so well. You've inspired me to take advocacy to a whole new level!

  14. You forgot one….vitamin K2. K2 is made by bacteria like B12 and many vegans are deficient. And what's with showing vitamin D2 while talking about vitamin D deficiency? Isn't vitamin D3 the preferred form?

  15. You have come a long way, Dr. Greger! This presentation has some of your best information but very worst voice presentation. It demonstrates your skills that you upgraded your presentations so rapidly. Your narration of "how not to die" was simply excellent!!

  16. It's very discouraging when vegan doctors on YouTube and other vegan doctors referred to by said doctors have completely different opinions on taking vitamin d supplements. Who is correct?

  17. I wonder if we could isolate the specific bacteria responsible for the B12 in murky stagnant water, let it fester in a vat, and then sell it as super water to vegans everywhere

  18. You’re a real hero for what you do! Love all your videos I watch them all day. Could you do a video going over research and studies on fillers in supplements. Like magnesium stearate and titanium dioxide. There’s a ton of controversy and and lack of information regarding sourcing and health effects. I would trust it coming from you! Thank you doc you’re awesome!

  19. All these years later, & vitamin D is the key to warding off Corona virus & encourages mylin sheath regeneration for ms patients… the miracle vitamin
