Fat-soluble form of vitamin C used as preservative

How to take it

With food

Tryptophan 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 protein-heavy meals
Space it a couple of hours from SAMe

On the label

As a dietary supplement, take 2 capsules, 1-2 times daily, between meals.

Do not combine with St. John's Wort

Each of these raises serotonin activity on top of St. John's Wort, and together they can trigger serotonin syndrome — agitation, rapid heartbeat, raised blood pressure. Not without medical supervision.
