How to Take It

Best taken in the evening

The PS in it is what pulls this toward the evening. Take it with a meal containing fat — the vitamin E in it absorbs poorly without one.

With a meal containing fat
Label directs 2 servings — keep one for the evening

On the label

For the first month take 2 softgels 3–4 times per day. After one month take 2 softgels 2 times per day or as directed by a health professional.

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