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
Iron does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.
Keep it away from coffee, tea and dairy
Space it a couple of hours from Calcium, Zinc, Magnesium, Manganese and Green Tea Leaf Extract
On the label
Adults: take 1 to 2 tablets daily with food or as recommended by your healthcare professional
General guidance based on the ingredients, not a substitute for the label or your doctor.
