After protein, vitamin b12 is one of the greatest concerns people seem to have when considering a vegan diet. While I’ve already done a full video on B12, I would be remiss if I didn’t ask Dr. Michael Greger of Nutritionfacts.org for his thoughts on this vital vitamin. He discusses supplementation, genetic factors, and b12 sources. Track your vitamin B12 with Cronometer: http://www.BiteSizeVegan.com/Cronometer

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?
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
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?
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.
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
Maybe our ancestors have eaten so many animal products (even most of us, when we werent vegan) that our DNA has recorded this life style and is very difficult to erradicate it.
Im not saying people is lying about others should be taking supplements (maybe is just lack of information, which doesnt mean they do it in an evil way, just incomplete).
So that would explain how Gary Yourofsky has lived enough without getting sick.
I do have a b12 deficiency and low testosterone on a Vegan lifestyle I've been a vegan for a year now I don't know how to get high amounts of testosterone and cholesterol I know it's low because I'm 15 and not getting erections or aroused it's been like this for months
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.????
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?
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!! 💜
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.
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 )
ahh gerger is an idiot
b12 you supplement why supplement if you get it in diet on wait you dont
you also do not get vitamin A , non existence in vegan diet
you do not get vitamin D comes from the sun but also has to have cholesterol to create it, greger forgets that woops
you also do not get dha one of the most important fats
you do not get zinc, iron, or calcium woops
Vegans have lower vitamin B12 concentrations, but higher folate concentrations, than vegetarians and omnivores. Half of the vegans were categorized as vitamin B12 deficient and would be expected to have a higher risk of developing clinical symptoms related to vitamin B12 deficiency.
Vegan subjects and, to a lesser degree, subjects in the LV-LOV group had metabolic features indicating vitamin B-12 deficiency that led to a substantial increase in total homocysteine concentrations. Vitamin B-12 status should be monitored in vegetarians. Health aspects of vegetarianism should be considered in the light of possible damaging effects arising from vitamin B-12 deficiency and hyperhomocysteinemia
meat eaters do not only eat meats they eat veggies durrr
trans fats are bad no one questions that
saturated fats are part of the essential fatty acids we need science says they do not cause heart disease
cholesterol is needed our bodies produce 3000mg of it a day it is used for steroid hormones, bile, brain health and cardio health again greger is an idiot
He says ''.....and it's not made by animals either...''. This gives the illusion that B12 can not be obtained any other way than by a supplement as well water, which he says is were we used to get B12, is now unavailable. Well he is wrong.A 3-ounce serving of Beef liver provides 2951% of DRI, A 3-ounce serving of Mackerel provides 667% of DRI, A 3-ounce serving of Sardines(most cans are 3-4 ounces ea.) provides 333% of DRI, A 3-ounce serving of Red meat provides 208% of DRI, One cup (8 fluid ounces)of Milk provides 50% of DRI. I could go on. There may be people thinking of taking up a Vegan diet, and if that is what they want to do then good on them, but I dislike people like this 'Dr' who is making claims that are incorrect.
Just thinking. Where did you get the incorrect information about farmed Mackerel and Sardines?. Seriously, did some one tell you it and you just believed it without even thinking of checking if it was correct? or did you just make it up?.
Again more misinformation. Mackerel and Sardines are NOT farmed. They are wild caught in nets and, thus, have non of the soy, corn or antibiotics which you wrongly stated they have. As for Beef, yes, totally agree that it should be grass fed........which is what I ALWAYS purchase. As for the milk?, well, I buy raw milk from the farm just down the road from me and as all my family have lived into their late 80's and 90's I'm not going to lose any sleep over it.
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!
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
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.
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
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.
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.
But I don't think she needs to comment on that lol. Gary's awesome and that's his opinion which is totally acceptable. She's also great and this is her opinion which is also completely acceptable.
I think it's amazing that we have 2 incredibly good people that are good friends with eachother and can peacefully acknowledge that they have different views on B12.
It gives us nice thought-diversity and an opportunity to see their individual perspectives. :-)
With peace and love <3
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 :)

The majority of women in this country are overweight. Believe it or not. If that's what you like fine. And because of this woman's diet she is more than likely healthier than those overweight rib eating women. To each his own.
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.
