The vascular team
L-citrulline
Converted by the kidneys into L-arginine, which the vessel lining uses to make nitric oxide. Studies have looked at citrulline's effect on nitric oxide levels and blood pressure.
Pine bark extract
French maritime pine bark contains procyanidins; research has examined its role in endothelial function and blood pressure.
Grape skin extract
A source of resveratrol and other polyphenols that support antioxidant defences.
The heart and wellbeing team
L-carnitine carries fatty acids into the heart's energy factories. Niacin supports circulation and cholesterol metabolism. Zinc supports antioxidant enzymes. Maca supports energy, and saffron supports a balanced mood.

Common questions
What does L-citrulline do?
The body converts it to L-arginine, which is used to make nitric oxide, helping blood vessels relax.
Why can niacin cause flushing?
It widens small blood vessels in the skin; the warmth and redness are usually temporary.
How much is in the proprietary blend?
570 mg per capsule, plus 20 mg niacin and 11 mg zinc.
