How to Take It
Best taken in the morning
Many people prefer B-vitamins earlier in the day; take with food to avoid nausea.
With food
On the label
Adults take one (1) capsule daily, preferably between meals.
The label says to take it on an empty stomach. What's in this one sits better with food, and you give up little by taking it that way.
General guidance based on the ingredients, not a substitute for the label or your doctor.
