How to Take It
Take it anytime
"No-flush niacin" — it genuinely doesn't flush, because it's poorly absorbed and doesn't reproduce nicotinic acid's effects on blood lipids either.
With or without food
On the label
As a dietary supplement, take 1 capsule, 1-4 times daily, with meals, or as directed by a health professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
