At age 50, everyone should start supplementing with B12-fortified foods or supplements regardless of the type of diet they follow. Over age 65, only high-dose daily supplements may suffice. For prevention and treatment of vitamin B12 deficiency, cyanocobalamin in chewable, sublingual, or liquid forms (rather than in a multivitamin) is best under most circumstances.
What about concerns regarding B12 and acne, bone fractures, and cancer? I addressed those in my B12 webinar, and the videos are available for download here or on NutritionFacts.org ([ Ссылка ]). I covered a lot: the dosage needed to treat B12 deficiency, how oral is better than injectable, why the cheaper form (cyanocobalamin) is superior to the more expensive form (methylcobalamin), why you can’t just take it in a multivitamin, and why you shouldn’t take it as a pill you swallow (because it needs to mix with that saliva protein).
I mentioned my book, How Not to Diet, which you can find out more about here ([ Ссылка ]). You may also be interested in my next book, How to Survive a Pandemic ([ Ссылка ]), available in softcover, audiobook (read by me), and e-book form.
