I was about to go out and buy a something which had B6, B12, and zinc when I noticed I had a bottle of centrum multivitamins. Each one had something like 300 percent B6 and B12, as well as zinc! The only problem is, a multivitamin might cost more than just plain B6,12 and zinc. But the wide range of vitamins it contains seems like a good enough reason to pay a little more.
I have been taking Centrum Performance. It is basically like normal centrum except most of the ingredients exceed normal daily values.
I thought I would compare the contents of Centrum Performance to Nature Made Stress B-Complex w/zinc, so you can get the idea how it compares to a b6/b12 supplement.
Vitamin B6 : 5 mg - B-Complex
6 mg - Centrum
Vitamin B12: 12 mcg
18 mcg
Zinc: 23.9 mg
15 mg
Not sure what impact these increased amounts have. Maybe a placebo effect, lol.
If there is A,D,E or K in it you shouldn´t take large amounts/take it too often. (these vitamins stay in your body fat instead of getting out with urine)
