or at least 50 mcg daily of supplemental cyanocobalamin. or a serving of B12-fortified foods three times a day, each containing at least 190 percent of the Daily Value listed on the nutrition facts label. Those over 65 years of age should take at least 1,000 mcg (µg) cyanocobalamin every day. And, here’s a tip: If you’re experiencing ...
Now, that’s just one of three methods you can use. A simpler and cheaper way is to take a single dose a week. If you want 3.5 in you a day, then you’d want to get at least 24.5 in you in a week. To get that in a single dose you’d have to theoretically take about 2,600, which I round in my recommendations to 2,500.
Getting enough vitamin B12 is absolutely nonnegotiable for those centering their diets around plant-based foods. For adults under age 65, the easiest way to get B12 is to take at least one 2,000 mcg supplement each week or a daily dose of 50 mcg. Note that these doses are specific to cyanocobalamin, the preferred supplemental form of vitamin ...
This 1.5-hour live webinar explained the rationale for Dr. Greger's new vitamin B12 recommendations. He discussed the symptoms of B12 deficiency and explained how he arrived at what he considers the optimal dose of vitamin B12 supplements in children, adults, the elderly, and during pregnancy. He clarified why cyanocobalamin (not methylcobalamin) is the best type of vitamin B12 supplement and ...
Wrong. Cyanocobalamin “is the most used form due to its high stability.”. See, “methylcobalamin is less stable than cyanocobalamin, and it is particularly susceptible to photodecomposition,” meaning destruction from being exposed to light. “There is no advantage to using the light-sensitive forms of cobalamin, such as methyl B12 ...
At least 2,000 mcg (µg) cyanocobalamin should be taken once each week, ideally as a chewable, sublingual, or liquid supplement taken on an empty stomach. OR, at least 50 mcg of supplemental cyanocobalamin should be taken daily (you needn’t worry about taking too much) OR servings of B12-fortified foods should be eaten three times a day (at ...
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.
The recommendations change to everyone taking a high daily dose of 1,000 mcg every day. Starting at age 50, everyone––meat-eaters and vegans alike––should be taking B12 supplements or eating B12-fortified foods. But over age 65, 50 a day may not do it. Even 100 a day doesn’t seem sufficient.
As I discuss in my video The Optimal Vitamin B12 Dosage for Adults, adults younger than 65 should take at least one 2,000 mcg (µg) supplement once a week, ideally as a chewable, sublingual, or liquid supplement taken on an empty stomach, or at least one 50 mcg (µg) daily supplement. As we age, our ability to absorb vitamin B12 may decline.
Updated Vitamin B12 Recommendations Infographic. Vitamin B12 is not made by plants or animals, but by microbes that blanket the earth. In today’s sanitized, modern world, the water supply is commonly chlorinated to kill off any bacteria. So, while we don’t get much B12 in the water anymore, we don’t get much cholera, either, which is a ...
