Nitric Oxide Needs
Nitric oxide opens blood vessels, lowers blood pressure, and fuels performance. Some people produce plenty on their own; others run low and don't know it. Lower producers often see dramatic benefits from beetroot, leafy greens, or targeted supplementation—it's one of the easiest performance wins available.
What this measures
How your DNA shapes nitric oxide needs.
NOS3 (endothelial nitric oxide synthase, covered for cardiovascular response to MUFA in batch A) also governs the nitric oxide production critical for exercise performance, blood pressure regulation, and erectile function. NOS1 and NOS2 (neuronal and inducible forms) contribute in specific contexts. Nitric oxide relaxes blood vessels and is the fundamental signaling molecule for vascular health.
Carriers of NOS3 reduced-activity variants are associated with lower baseline nitric oxide production, less vasodilation under exercise demand, higher resting blood pressure, and reduced response to endothelium-dependent stimuli. Carriers of typical-function variants tend to maintain robust vascular function on default lifestyle inputs.
L-citrulline (more reliable than L-arginine for systemic NO support), dietary nitrates (beetroot, leafy greens, especially before exercise), and pomegranate all support NOS3 activity. Vitamin D, B12, and folate are required cofactors. Endothelial damage from smoking, high blood sugar, and chronic inflammation suppresses NOS3 directly.
Athletes use beetroot juice and citrulline before training for a reason — and the reason is bigger for carriers of the reduced-function NOS3 variant. Which version you carry decides whether dietary nitrate is a casual addition or one of the most-actionable performance levers available.
Nitric Oxide Needs is one specific finding in this system. Your Genomic Lifestyle Optimization Report shows where your variants place you on the athletic performance spectrum — and what you can do about it: it renders as a dark card with a color marker calibrated to your variants, opening with the gene mechanism and closing with a practical, mechanism-led recommendation.

Bone Density Support Need
Peak bone density and lifelong resilience are genetically determined. Some people naturally build dense, fracture-resistant bone with minimal effort. Others benefit from earlier, targeted loading and nutrition to reach the same strength, and knowing which camp you're in determines whether you can coast or need to be proactive.
Read insight →Cardiovascular VO2 Max
Your heart's stroke volume and oxygen delivery set your aerobic baseline before you ever lace up a shoe. This tells you how much endurance potential you're starting with—and how to train it most efficiently instead of wondering why you're gasping while your training partner chats.
Read insight →Cartilage Support Need
Cartilage maintenance differs markedly from person to person. Some preserve healthy joints for decades of hard use; others show early wear despite doing everything "right." Your profile guides proactive protection—so you're still moving well at 60, not scheduling a knee replacement.

Slow-twitch fiber proportion and mitochondrial density largely determine how long you can sustain effort before the wheels come off. Aligning training and sport choice with your natural profile accelerates progress and eliminates the frustration of fighting your own physiology.
Read insight →Lumbar Disc Support Need
Collagen quality and hydration capacity in your spinal discs vary widely. Higher vulnerability benefits from early core stability work and movement mechanics—often preventing the "one wrong bend" injury that sidelines people for months. This is the kind of thing you want to know before it happens.

How efficiently your cells turn oxygen into usable energy (ATP) sets your daily stamina and workout capacity. If yours is naturally lower, targeted nutrition and training protocols can close the gap—but only if you know there's a gap to close.
