How to use it
- Take 2 capsules a day with food.
- Don't take more than 2 capsules a day.
The label notes temporary flushing, itching, rash or stomach upset may occur. One serving has 100 mg of vitamin B6, which is NIH's daily upper limit for adults, and 100 mg of niacin, above NIH's 35 mg limit for niacin from supplements, so don't add other B6 or niacin supplements without asking your doctor. Talk to your physician first if you're pregnant or nursing or have a medical condition. Keep out of reach of children.
A good fit if you
- Want all eight B vitamins in one formula
- Prefer methylcobalamin and methylfolate to cyanocobalamin and folic acid
- Want B vitamins to support energy metabolism

Common questions
Which B vitamins are in it?
All eight: thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), B6, biotin (B7), folate (B9) and B12, plus inositol and PABA.
What forms of folate and B12 does it use?
Folate as L-5-methyltetrahydrofolate calcium salt (680 mcg DFE) and B12 as methylcobalamin (300 mcg).
Why might I notice flushing?
The label says temporary flushing, itching, rash or stomach upset may occur. NIH notes the nicotinic acid form of niacin can cause skin flushing, and this formula uses niacin along with niacinamide.
How do I take it?
2 capsules a day with food. That's 30 days per bottle.
