How to Take It

Best taken in the morning

The Vitamin B6 in it is what pulls this toward the morning. Take it with a meal containing fat — the vitamins A and D in it absorb poorly without one.

With a meal containing fat

On the label

Take 1 teaspoon 1-2 times a day with a meal, or as directed by your healthcare professional. SHAKE WELL BEFORE USE.

General guidance based on the ingredients, not a substitute for the label or your doctor.
