Full Description

Nitric Oxide Supplement

What Is It?

Nitric Oxide Support is an arginine-based formulation designed to support healthy nitric oxide production, facilitate ammonia and lactate removal to moderate fatigue, support immune health, maintain acid-base balance and provide antioxidant protection. It is available in a lemon-lime flavored powder for convenient dosing.‡

Uses For Nitric Oxide Support

Supports nitric oxide production and healthy blood flow‡

  • Contains arginine, a nitric oxide precursor, to support healthy circulation and delivery of oxygen to working muscle‡
  • Provides citrulline to delay the onset of muscle fatigue, maintain acid-base balance, promote aerobic energy production in muscle cells during exercise, and enhance arginine and nitric oxide production‡
  • Includes vitamin C to enhance nitric oxide activity and provide blood vessel endothelial antioxidant protection‡

Moderate Fatigue:

Arginine may protect muscles from oxidation and moderate lactate dehydrogenase activity during intense exercise. In one study, citrulline malate provided potential support for aerobic energy production and fatigue reduction. Double blind, placebo-controlled studies indicate that arginine and citrulline help to relieve muscle fatigue and maintain healthy acid-base balance, primarily by serving as intermediates in the urea cycle, which helps to eliminate ammonia

Growth Hormone Production:

Arginine plays a role in the synthesis of growth hormone, which may help support lean mass and muscle repair.* Immune Health: Research has suggested that arginine may support immune health, in part by facilitating nitric oxide use by immune cells and enhancing immune cell communication.
