How to Take It
Best taken in the morning
The Vitamin B2 in it is what pulls this toward the morning. Take it with a meal containing fat — the vitamins D and E in it absorb poorly without one.
With a meal containing fat
On the label
Consume 1 tablet daily. Best taken with food. Warning: Not recommended for children, pregnant or breastfeeding women. Consult with your doctor if taking medication or have a medical condition. They’re so simple to make part of your regime — just take one tablet a day with food.
