L-Arginine

This physician-formulated cardiovascular and performance formula delivers high-potency L-Arginine—the primary precursor to nitric oxide (NO)—alongside synergistic vasodilatory nutrients. L-Arginine targets key vascular, cardiovascular, and metabolic pathways involved in nitric oxide synthesis, blood flow regulation, and cellular energy in adults seeking heart health, endurance, and exercise performance support.

•        Supports nitric oxide production and healthy vascular tone

•        Promotes cardiovascular health and healthy blood pressure balance

•        Enhances athletic performance, endurance, and exercise capacity

•        Supports muscle protein synthesis and post-exercise recovery

•        Promotes healthy erectile and sexual function via vascular support

•        Supports immune function and wound healing

L-Arginine is a semi-essential amino acid that serves as the primary substrate for nitric oxide synthase (NOS) enzymes, which convert L-Arginine into nitric oxide (NO)—a critical vasodilatory signalling molecule. Nitric oxide relaxes vascular smooth muscle, promotes endothelial health, supports healthy blood pressure, and enhances tissue perfusion and oxygen delivery. L-Arginine also participates in the urea cycle, creatine biosynthesis, and protein synthesis, making it a multifunctional cardiovascular and metabolic nutrient.

L-Arginine (Free Form)

The primary amino acid precursor to nitric oxide, synthesised via the NOS enzyme pathway. Supplemental L-Arginine supports vascular relaxation, endothelial function, healthy blood pressure, and tissue oxygen delivery. Also contributes to creatine and polyamine synthesis supporting muscle and immune function.

L-Citrulline

An amino acid that is converted to L-Arginine in the kidneys via the citrulline-arginine-NO cycle, effectively extending and amplifying the duration of L-Arginine availability for NO synthesis. L-Citrulline supplements the body's arginine pool more efficiently than additional L-Arginine alone.

Vitamin B3 (Niacin)

Supports cardiovascular health by promoting healthy HDL cholesterol, reducing triglycerides, and supporting endothelial function. Complements L-Arginine's vascular benefits and supports energy metabolism.

Vitamin B6 (Pyridoxine HCl)

An essential coenzyme involved in amino acid metabolism, including L-Arginine utilisation, homocysteine regulation, and NO-related biochemical pathways that support cardiovascular health.

Pine Bark Extract (Pycnogenol)

A potent proanthocyanidin-rich botanical extract that enhances nitric oxide synthesis, supports vascular endothelial function, and provides antioxidant protection for blood vessel walls—synergistically amplifying L-Arginine's cardiovascular benefits.

Support Area	Key Ingredient Action
Nitric Oxide Production	L-Arginine serves as the primary substrate for NOS-mediated NO synthesis
Extended NO Availability	L-Citrulline replenishes arginine pools for sustained NO production
Cardiovascular Lipid Support	Niacin supports healthy HDL and triglyceride balance
Amino Acid Metabolism	B6 supports L-Arginine utilisation and homocysteine regulation
Endothelial Antioxidant Defense	Pine Bark Extract protects vascular walls and enhances NO bioavailability

 

Nitric oxide is one of the most important signalling molecules in cardiovascular physiology, governing vascular tone, blood pressure, endothelial health, and tissue perfusion. Age-related decline in NO synthesis, metabolic stress, and endothelial dysfunction can impair cardiovascular function and athletic capacity. L-Arginine-based supplementation targeting NO production and vascular health may support a healthier cardiovascular system, improved exercise performance, and overall metabolic vitality.
