1. I'm actually enjoying the longer videos! I feel like I'm watching a mini documentary every time. The shorter 2 min videos I felt would always leave me wanting more information. These longer ones have more detail! thanks!!

2. Very informative. Thank you for focusing also on nutrition and not always on veganism vs meat-eating nutrition.

3. I agree.

4. I have a vegan Vitamin D3 that is sourced from mushrooms. Can you explain how they make them?

5. do you work for the beef company

6. hmmm i think Jameth Sheriden sid the reverse… i gotta check into that

7. Why isn't there a vitamin D1?

8. any correlating date to high levels of supplemented VitD to the need for some to then supp with VitK/K2?

9. See Dr. Greger's video "Toxins in Raw Mushrooms".

   Agaratine, a natural toxin found in mushrooms, is destroyed by cooking

10. i wish the donation options started at $5, then went up to $10. that is all.

11. Dr. Cannell who is as far as i know one of the most prominent researchers of vitamin D at the moment, has said some damning thing about the efficacy of vitamin D2. Look him up and try to find his interview with Dr. Mercola here on youtube.

12. I did not know that you could get vitamin D3 supplements from plant sources. That's a relief.

13. You can't. Cholecalciferol is only made by animals.

14. It's not rare, it's impossible. Plants don't make cholesterol. It's basic biology.

15. @madmagrider I know. I was being sarcastic.

16. Concordo!

17. Is Vitamin D3 Really Better Than D2?

18. In Asia we traditionally use dried mushrooms a lot in our cooking 🙂 Wisdom ftw 🙂

19. I intend to take D3 at some point … but fie, I just can't get myself to swallow capsules ….

20. C3PO says R2D2 is better than D2 or D3 combined…

21. At 3:08 he says "and if you're not vitamin D deficient…. D2 from mushrooms or supplements doesn't appear to raise your levels (of serum 25 (OH)D) further"

    Does this mean that vitamin D2 is less likely to cause toxicity? Since once you reach a healthy level its harder for more doses of D2 to keep raising levels like D3 does?

    I would love Dr.Michael Greger to answer this.

22. I get my D3 via lichen or unprotected sun exposure #Vegan

23. Is anyone aware of any research into the presence of BMAA in lichen based D3 supplements? as i have read that it has been detected in some varieties..

24. So what's the bottom line? I didn't get it..

25. but doc, D3 isn't vegan. it's derived from wool, so it's not cruelty free

26. did the dude shine the uv on cut mushrooms or was he growing them?

27. How does one find Vitamin D3 supplements without oil?

28. I also expose portobello mushrooms to UV or sunlight, though at this moment I'm getting enough from the sun

29. Most of the studies I've read describe D3 as more bioavailable than D2, specifically that it has a more direct pathway to being converted into an active nutrient [25(OH)D], as opposed to D2 which metabolises into ercalcitriol, albeit a similar compound to [25(OH)D]. D2 is most certainly not metabolised into D3 as I'm reading others suggest in the comments here. D2 does not have a low half-life because of some conversion into D3, from what I've read, this is not how the compound is metabolised in the body. D2 has a lower half-life because it is not fat-soluble and will break down in the body within about a week, whereas D3 is fat-soluble and may persist in the body for up to a few months (making it much more viable for those suffering from Seasonal Affective Disorder).

    I don't understand why, as a self-professed nutritionist and plant-based promoter, you'd overlook this information to promote the consumption of mushrooms, particularly mushrooms that more than not need to be exposed to UVB lighting for several reasons which are staggering, at least to me. 1) As if the process of maintaining one's nutrition wasn't convoluted enough, your audience should figure out that if they don't live by a provider of vitamin-D2 rich mushrooms (or the knowledge of how to find them, especially in food deserts), they should set up a lighting system and/or outdoor mushroom sunbathing area, know that they'd need a light source that provides UVB radiation, not UVA, and have the knowledge of how to preserve their mushrooms in the process. 2) For those without access to consistent, quality sun-exposure (i.e. the majority of Western society), we're going to promote a completely esoteric and tedious means of procuring an extremely vital nutrient when simple, affordable solutions exist (which is mentioned, to your credit). 3) It's not as if Vitamin D deficiency is a new thing. This has been an issue for a long time and has been the bane of those considering a plant-based diet before it began to become the trend that it is now, along with b12 and iron, which have far less esoteric and strange means of resolving. Yeah, get sunlight, simple solution, but that's not available to everyone. Go out and buy a sunlamp or drying racks to set up mushroom radiation stations in your home/yard for a less bio-available form of the nutrient… How is this even considered an alternative option?

    Just supplement D3 with capsules that derive the nutrient from lichen. They're not expensive supplements. You can order them online. To my knowledge, their procurement is not harmful to the environment They've been around for a while. Simple solution. Or do your head in and figure out how to properly radiate mushrooms for a nutrient that won't even be consistently bio-available in your body for over a week and give yourself another chore. Really, I can't fathom how that's the body of this video. It may go without saying, but I'm disappointed with the lack of forethought that went into how this information (or lack thereof) would impact those looking to resolve the common issue of vitamin-d deficiencies in vegans.

30. Can you talk normally?

31. Great information. The following video describes the research demonstrating how vitamin D is critical in all stages of COVID-19 as well as why vitamin D stops the cytokine storm and blood clotting.https://youtu.be/sjyZH3Ib4Ws

32. Thanks for this dr g
