The B 12 is made from a natural source and it is at higher than average dose of 1,000 mg, (natural source of Methylcoba... .) I had a B12 deficiency, so far down that I had enemia. After taking the natural B12 ( with larges dosages than just the multi), for 3 months it is now shown as "high." I've also learned that Thiamin, B1, is also often low in people. So I'm very glad this multi has a high dosage of 60 mg, that is 5,000% of the "daily value." Some multi B vitamin products show the same amount for just about every vitamin listed, like all 50 mg. However this vitamin is more specific. I appreciate it that all the amounts are relatively high. A good bargain. Review: What a Steal!...Great Product!...Contains 100% methyl-Folate/Quatrefolic/5-MthF! - Thrilled to find methylated/co-enzyme/active B-Vitamins at such a great price. Methylated B vits. are fully active, your body does not have to 'convert' these in to a usable form - they are already fully absorbable & ready to get to work in your body - - unlike 'old-fashioned'! non-methylated B's (i.e.: B50 complexes & the like) which actually require your body to 'convert' those to a usable form, this process itself is difficult for the body/liver & more so for certain genetic 'mutants'! - Long story short - methylated/activated/co-enzyme B-Vitamins are far superior (my opinion!) & better absorbed than the kind of B-complexes you might find at your local drug-store or Gas Station .... I used to use Jarrow 'B-right' but they changed the formula to contain a mix of synthetic/fake Folic acid & 5-mthf, whereas the Doctors Best brand contains 100% Quatrefolic (5mthf) - so Doctors Best is my preferred choice now! .... I get a definite boost in energy & mental clarity .... I take these every day along side my Amino Acids - the B's ensure that the Aminos can do their job And of course a healthy daily intake of B's is essential for practically every process in the body & to help the Liver keep on humming-along! Two big thumbs up for Doctors Best fully Active B-complex! The product got here (Hawaii) very quickly - 2 days faster than anticipated arrival! desertcart outdoes itself yet again! ## Features - SUPER VITAMIN B COMPLEX: Our B complex vitamins for women and men include Vitamin C as ascorbic acid, thiamin, riboflavin, niacin, Vitamin B6, folate, Vitamin B12, biotin, and pantothenic acid - METHYLATED B12 & FOLATE: Fully Active B Complex provides Vitamin B12 as methylcobalamin along with Quatrefolic, a bioactive and highly absorbable form of folate for optimal support - ENERGY & CELLULAR SUPPORT: This unique, comprehensive formula offers high bioavailability and optimal support for energy production, cellular health, and overall well-being - SUGGESTED CAPSULE USE: Take 1 capsule daily with food, or as recommended by a nutritionally informed physician.
