1. are most supplements vegan? how would I be able to tell if a supplement is vegan if it does not specify on the label?

2. Does anyone no if blue spirulina has b12 in it

3. I think Dr Greger is your "spirit dad". I enjoy your commonality of creative humor, academic work, and natural homespun delivery. You even look alike! Thanks to you both.

4. why does supplimenting in vitamin b12 work but supplimenting in a multivitamin does not ?

5. Dr. McGregor is funny. Those supplements he recommends are very often mislabeled. What it says on the bottle is not what is inside. just check the internet on that information. Also that it is cheaper then shots. Weird as I inject myself and one shot hydroxocobalamin costs me 1 eur. I rather have a pharma product which has proper quality control then the crap they sell in those bottles.

6. I heard cyno is ultra synthetic and has cinide in it, weird

7. kombucha, kimchi, rejuvelac.
   rejuvelac makes the best damn raw cashew vegan cheese on the planet.
   i still supplement though its like insurance.

8. Just had an extensive argument with someone that the science here is wrong.
   I did a simple google search and it pretty much said what you guys said.
   Do you have any sources I could throw at them?

9. Why should we trust supplement industry?

10. Great informative video. Good job! 🙂

11. crap I bought all the expensive methyl T_T shakes fist I actually wouldn't care but when he noted that all the testing was done on cyano….I want to go buy cyano now ;-;

12. Can someone give me citations for the information she provided.

13. I'm starting to go vegan & if I take a Vitamin B12 supplement how often should I take it? Is it every day?

14. Hi Emily, do you know of a vegan name brand of B12 supplements? Thanks 🙂

15. Try nutritional yeast. Its the best non supplement source of b12. It's just deactivated yeast flakes and has many other nutrients in it. You can buy it from places like "whole foods" it tastes very good on a lot of stuff too. It kind of has a cheesy flavor to it but there's no dairy so it's still vegan 🙂

16. Thank you Bite Size Vegan!

17. What about muscle and brain tissue creatine and carnosine levels

18. Your mentor Gary Yourofsky promotes not taking b12 supplements, do you care to comment on that?

19. I use nutritional yeast for b12. It can go a long way and comes with more than just b12, I also like the taste with certain foods. I bet nutritional yeast is a cheaper source too but it's hard to say for sure, I haven't examined and compared costs exactly.

20. Can anyone here please recommend vegan tablets containing 2500 mcg vitamin B12 (cyanocobalamin)?
    Listening to this video it seems as if the search for this should be easy as a vegan cake walk, but weirdly the opposite is the case: Where ever I look, all I can find online is 1000 mcg methylcobalamin, rarely I bump into cyanocobalamin and then only in small doses like 500 mcg.

21. what about fermented foods like kombucha? Do they contain vitamin B12?

22. He didn't mention that some people don't absorb B12 in their stomach properly, they are missing the intrinsic factor and or have low stomach acid that's how you get pernicious anaemia, they would need to get an injection or use a mouth spray or patches. Also some people are allergic to cynocobalamine like me, I break out in a rash

23. Hi, thank you for your awesome videos. What is the daily required intake for methylcobalamin en cyanocobalamin and methylcobalamin? thank you! Peace from Belgium.

24. Hi. I can´t make people understand why i´m vegetarian. It´s really stressing when i´m talking to someone that has no idea of what he´s taking about. Any advice?

25. Haha! I used to do this in class when a teacher was reading answers to a worksheet and they´d say B 5 I´d always yell bingo! nobody got it until a new student transffered who laughed histerically when I did that.

26. How do you explain that after taking 8 grams of SugaVida daily blood levels of Vitamin B12 increase by over 60% after 28 days?

27. does it has to be sublingual? I live in europe and in the instructions it just says to swallow it, 30 micrograms a day. It also says it's 1200% the recommended dosage I'm confused 🙁 it is cyanocobalamin

28. You sunk my battleship!

29. Great video! Thanks for asking the right questions. You have a new subscriber.

    That being said, I wasn't convinced about the cyanocobalamin vs methylcobalamin part. I tested positive for a very common gene mutation called MTHFR and from reading I've come to the conclusion cynanocobalamin is the wrong choice for me. Any thoughts? Thanks!

30. I love your videos they are so spot on. I've been doing research of my blood and other people with the rare resilience and came to a dead stop. You were my inspiration for this research

31. I don't like the way I feel when I take cyanocab. I'll stick to methyl.

32. Good, sharable information! And I love her sense of humor! 😀

33. thank you so much for your work 😙😙😙😙

34. Youre the best girl ! ✌🏽️❤️🌎

35. Is 100 mcg of b12 every day enough? That is the amount in my deva vegan multi vitamin

36. En Españollll PLZZZ!!!!!!

37. Just get a little dirt in your diet people.

38. U are doing a fantastic job, all the best.

39. Why does my organic baby bella mushrooms boxes say that they contain vitamin "D" ???? 🍄🍄🍄🍄
    As for my B12, I INTENTIONALLY do NOT rinse my vegatables (especially my celery, spinach, potatoes,🥔🥔🥔🥔 carrots, 🥕🥕🥕🥕and more…) in ORDER TO GET MY Vitamin B12,l FullyRawKristina style!!🍒🥕🥔🥜🥑🥒🍅🍓🍒🍒🍑🍌🍌🍌🍌🍊🍋🍍🍎(Look at her B12 vlog on her channel )

40. I am newer to a vegan diet and have a specific question about the B12. I have heard that if our B vitamins are out of balance, that it can cause health issues. For example, most multivitamins skimp on the expensive B vitamins, like biotin, and add a lot of B12, because it's so cheap. So I'm wondering if it would be better to take a balanced B complex, rather than taking B12 all by itself.

41. what do you think about Gary Yourofsky telling in the speeches he gave that b12 is produced naturally and that he hasnt taken b12 supplements?

42. You're so creative, I went vegan because of your lovely nuggets, you're so inspiring person, I wish one day I'll have this power to be an activist and to meet such a lovely person, much more power Emily!! 💜

43. The beanie 😟

44. i drink tank/rain water ….. would that be full of b12 due to dirt of the roof etc ?

45. marmite contains b12

46. great info. thanks. Can you do a video on paleo Bullish!t.? 😉

47. We collect rain water, it goes down to a pre-built well, we then pump it to tank on top of the house and use it for drinking after it passes through a water filter (no sterilization), would it have B12 that way?

48. FASCINATING stuff! That cleared up everything I was wondering about B12. Thanks!!

49. i drink rainwater which has B12 in it, do you know if that would be enough to get my recommended amount?

50. Hi your video had some great information. 😊

    Is there any research on how to activate b12 in our food?

    I fear about b12 supplements because makes me ask the question: Where did the b12 supplement come from, how did they get it, and did they do it without extracting b12 from beef, chicken, ect.????

51. @ 4:13 if you were B 12 deficient you would take 2,000 mcg (of cyanocobalamin B12) per day for two weeks to restore your levels

52. Ok, now the question emerges where to get a decent cyanocobalamin without magnesium stearate in it, please?

53. Human body CAN PRODUCE and absorb vitamin B12. Check study "Vitamin B12 synthesis by human small intestinal bacteria" with following abstract: "In man, physiological amounts of vitamin B12 (cyanocobalamin) are absorbed by the intrinsic factor mediated mechanism exclusively in the ileum. Human faeces contain appreciable quantities of vitamin B12 or vitamin B12-like material presumably produced by bacteria in the colon, but this is unavailable to the non-coprophagic individual. However, the human small intestine also often harbours a considerable microflora and this is even more extensive in apparently healthy southern Indian subjects. We now show that at least two groups of organisms in the small bowel, Pseudomonas and Klebsiella sp., may synthesise significant amounts of the vitamin." https://www.ncbi.nlm.nih.gov/pubmed/7354869

    5 years ago, when I started a Raw Vegan diet, my B12 was very low (probably I was deficient in the first place). It was only 126. I had tingling fingers, foggy head and I had very difficult time to concentrate. I took different B12 pills supplements, but nothing helped me, until I tried to eat SWEET CABBAGE. I eat it raw without processing or mixing it with anything else. Just take it and eat it. I felt so much better!!! My anaemia was gone! Since that time I had never took any vitamins supplementations, including B12. I live active live. I run 5k every day and I have long runs 20-30k each Sunday.

    According to this study, and my personal experience, you should not have any vitamin problems if you eat raw greens and fruits, and avoid preservatives, drugs, acids and other chemicals that can damage lumen of your intestine, because vitamin production and absorption takes place in lumen!

54. You are funny and wonderfull and I love you.

55. Excellant information. Thank you so much 😚

56. MAAARMITE!

57. Cyanocobalomin: cyano = CN which is Cyanide…

58. Methylcobalamin is more expensive because the methyl group takes more energy and processing in order to get a methyl group CH3 which is non-polar, its harder to get the functional group on to the cobalamin than the much more polar CN cyanide

59. I think u should make move video atlease every month

60. Which B12 is in untreated dirt and water? Also Cyanocobalamin or Methycobalamin.

61. Deficiencies in B-12 can result in fatigue, megaloblastic anaemia, early dementia, increased risk of heart disease, nerve dysfunction, forgetfulness, lack of coordination, and psychiatric disorders, as well as the possible development of neurological disorders in babies of breast-feeding mothers.
    This nutrient is only found in animal products (apart from some types of algae), and so it has been shown that as many as 92 per cent of vegans are deficient in this critical vitamin.

62. This helped alot thanks.

63. Great info as always! Thank you for sharing Dr. Greger’s input.🙏❤️

64. OMG he's not walking on a treadmill!!

65. Ruminants get their B VItamins from Microbes in their digestive System…

66. Such a great helpful video❤️❤️❤️

67. Sub in Spanish please

68. Hi! I have a question concerning biotin (B7) vitamin, I just started to use cronometer it seems there is not much biotin in anything that is vegan, it always comes out very low like 1%. Why is this because I looked up the vegan biotin food sources and introduced it to cronometer and is just not changing at all. Do you have issues with this?

69. Nice you just got a sub

70. Is Methylcobalamin vegan I'm confused isn't it found in animal sourced

71. I love the humor in the way you started this video! Also love all your videos, and your mission! Vegan on sister ✊🏽

72. I love you =) @bitesizevegan

73. You have beautiful tatoos <3

74. Dr said 2500 micrograms of cyanocobalamin sublingual per week.

75. Are there any reliable sources that I can refer a friend to in order to present the information about cattle being ROUTINELY supplemented B12, whether by injection or in their everyday feed??

76. I have been Vegan for a short time but B12 deficient for years. I used to get B12 shots but now I use the Trader Joe's brand.

77. Sub in Spanish or Latino please
    Thank you for all information.

78. How are farm soils more sterilized nowadays?

79. there are so many b12 supplements on the market. And as Dr. Greger said, you need “a reliable source” of b12. Many people can not integrate cyanocobalamin, and get severely mentally ill on a vegan diet. I personally think the methylated version is the best, and I would NEVER take a supplement with a cyanide precursor.

    Vegans: this is why meat is the safest source of b12. Because it is pure cobalamin. No one disagrees with this. That’s why we have to try harder than non-vegans.

    So just a head’s up for you guys 💗
    & if you are feeling sluggish and mentally weak, try switching to the superior methylcobalamin. (cyano = cyanide)

    ideally: don’t supplement, be natural.
    but if you are vegan, make sure you are ABSORBING your b12

80. Miss you 🙁

81. At the 2:40 mark [ https://www.youtube.com/watch?v=AvpePfC9hh8&t=2m40s ] dr. greger says simplest thing is to take 1 x 2500 microgram [mcg] tablet a week which is 2500/7 = 357 mcg/day but when I do search on "daily vitamin b12 recommendation" the mayo clinic hit [ https://www.mayoclinic.org/drugs-supplements-vitamin-b12/art-20363663 ] says "The recommended daily amount of vitamin B-12 for adults is 2.4 micrograms" which is over a 100x less than what's being suggested here unless I have my units messed up. Can someone shed some light on what the appropriate b12 rda really is?

82. I think you definitely need to supplement with D and K2 also…both critical for health.

83. You are amazing! Thank you so much for making this highly informative video!

84. At least he doesnt encourage people not to bother like Gary who thinks that bacteria in our body can produce it and we can benefit from it. I would like to ask the doctor how to switch to butanoic fermentation in our guts instead of acetic one which is harmful to our body. All this fibre turns out not to be good for us as acetates are cause of inflammation.

85. Nutritional yeast

86. How much b-12 should a vegan child get every day or every week?

87. Thanks but can you update this please!?

88. Love your videos…love your hilarious sense of humor.

89. Buckwheat

90. Dried nori sheets are a good source of b12 (not roasted, apparently) and broccoli sprouts have some but the nori has a much higher margin

91. i take methylcobalamin.. WHY IS IT SO DIFFICULT LOL this is just more reason to somehow get b12 naturally im so sick of worrying about fucking b12.. i heard cyanocobalamin has cyanide with it.. i cant even with this shit!

92. share a bottle of vitamin b12 with your friend!
    -actual advice from the Doctor 🤦🏻‍♂️

93. You are fantastic! Thank you Emily!

94. cant believe i just barely found your channel. Im about to complete my first year as a vegan and your channel would have been so helpful a year ago. very informative, educational, and well presented.

95. WHAT ABOUT WHEAT GRASS!?
    WHY IS NO ONE EVER TALKING ABOUT WHEAT GRASS!?
    Wheat grass is RICH in Vitamin B12 and it is a wonderful vegan source for B12. I grow wheat grass in my own garden and have been vegan for years. I incorporate wheat grass into my daily diet by inserting it into my smoothies, juices, salads, soups, stews, buddha bowls, etcetera. I have never had a deficiency in B12 in my life. Why do people keep claiming that vegans have ZERO access to B12 when wheat grass literally exists? I have been vegan for years and have been consuming wheat grass on a daily basis for years as well – never met a B12 deficiency in my entire life. (Without taking supplements). And yes, wheat grass is very much edible. Also, it is an amazing source of protein as well. Why is no one ever talking about it?

96. So glad I was brought up from a toddler to love Marmite on toast – masses of B12! Have it about 5 days a week for breakfast. Now I also use nutritional yeast as a condiment as well. Engevita is really good on pasta.

97. What are the signs of not having enough ? Can we take too much ? We have it in our Engevita yeast flakes with added B12

98. Newly subscribed, very much appreciated already, great channel. As a guy, I notice girls are programmed to choose taller mates because of some type of internal programming thing to better protect young or whatever, but if you look at it the heart is the same size whatever your height, 5'6" is about perfect they say. It's tough now because lots of kids are super-tall with all of the growth hormones and toxic things in the diet like sugar and everything. Seems to make children prematurely age also. It's so great being vegan now, eggs and meat and stuff have made me nauseous every meal of my life, it's a crime.

99. I get my b12 from fortified milk and nutritional yeast. I also have my yummy cherry flavored b12 vitamins that dissolve in my mouth 👄

100. so why's he saying methyl needs to be 1000 a day? Soucre? I wish you asked him why he said that

I commenti sono chiusi.
