L-Citrulline is the most effective precursor for raising arginine levels in the blood. It converts to Nitric Oxide in the kidneys, providing the gas needed to inflate the vascular system of the reproductive organs.

Aging naturally reduces the body's ability to produce NO by up to 50% by age 40. Supplementing with precursors bypasses the age-related decline in the eNOS enzyme, restoring youthful vascular reactivity.

Nitric Oxide (NO) is a signaling molecule produced by the endothelium that triggers smooth muscle relaxation in blood vessels, leading to vasodilation. This improves blood flow and lowers blood pressure.

As we age, our natural ability to produce NO declines. Precursors like dietary nitrates (from beets/arugula) or L-citrulline provide the raw materials to boost NO production, supporting endothelial health and maintaining optimal blood pressure regulation.

Nitric Oxide is a key antimicrobial molecule used by macrophages to destroy pathogens. It also improves microcirculation, delivering immune cells to the site of infection efficiently.

Nasal breathing increases Nitric Oxide production in the paranasal sinuses, which sterilizes incoming air before it reaches the lungs. This is your first line of defense against airborne pathogens.
