Therefore, it is generally safe to take extra B-vitamins, but there is no medical reason to do so, unless you have been diagnosed with a deficiency or are at risk of a deficiency due to certain medications or conditions. In general, try to get your nutrients from healthy foods. ...Read more

Is it safe to take 100mcg of vit B12 and 400 mcg of folic acid daily? My doc said I'm deficient. What would cause a deficiency in these?

Also, elderly people and those with genetic polymorphisms can absorb these vitamins poorly. Eating foods rich in B12 & folate (folic acid) (such as legumes & leafy greens) can help. Taking vit B12 and Folic Acid as your doctor suggests, is safe. ...Read more

If I just got a B12 shot n gonna for 4 more weeks n then 1 a month for B12 defieciency is it good 2 take additional B12 in pill form daily?

If you can't absorb it, taking it in pill form won't help. If the B12 is low because you are a vegan, oral B12 might help. ...Read more

Load it on: Five thousand micrograms per day is often cited. Vegans have the moral high ground but the health benefits mostly disappear when you control for the fact that vegans tend to have other healthy habits and don't overeat because the food isn't as good. You'll need more supplements as well if you want to avoid ruining your health; brain damage from B12 deficiency is a very real risk. Be smart. ...Read more

Sublingual b12, 500-1000mcg/day. The form of B12 (cobalamin) may be important; see comment. ...Read more
