They don't know if their NAD⁺ levels are critically depleted, marginally low, or already reasonably maintained. They have no way to measure whether supplementation is working. They are guessing.\u003c\/p\u003e\n\n\u003cp\u003eThis test changes that. The NAD Level Test measures both \u003cstrong\u003eNAD⁺\u003c\/strong\u003e (the active, oxidised form) and \u003cstrong\u003eNADH\u003c\/strong\u003e (the reduced form that reflects how efficiently your cells are using cellular metabolism). Together, these two measurements give you a complete picture of your cellular metabolism status — not just a number, but a ratio that reflects your redox balance and metabolic resilience.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Your NAD⁺ Level Matters More Than You Think\u003c\/h2\u003e\n\n\u003cp\u003eNAD⁺ is involved in over 500 biochemical processes — cellular metabolism production via the electron transport chain, DNA repair via PARP enzymes, circadian rhythm regulation via SIRT1, and mitochondrial biogenesis via PGC-1α. Every cell in your body needs it to function. When it runs low, almost everything runs less efficiently.\u003c\/p\u003e\n\n\u003cp\u003eNAD⁺ levels decline by roughly 1–2% per year from your mid-30s. By age 50, most people have approximately half the NAD⁺ they had at 25. This decline correlates with the fatigue, slower recovery, reduced cognitive stamina and metabolic changes that most people assume are just \"getting older.\" They are partly biology — but they are not inevitable.\u003c\/p\u003e\n\n\u003cp\u003eThe problem is that this decline is invisible. You cannot feel your NAD⁺ levels dropping. You cannot see them in a standard blood test. Until recently, measuring them accurately at all required a laboratory and specialist equipment. This test brings that measurement home.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Makes This Test Clinically Meaningful\u003c\/h2\u003e\n\n\u003cp\u003eMany health tests measure a single value. The NAD Level Test measures two: \u003cstrong\u003eNAD⁺\u003c\/strong\u003e and \u003cstrong\u003eNADH\u003c\/strong\u003e — and the relationship between them (the NAD⁺\/NADH redox ratio) is as diagnostically important as either value alone.\u003c\/p\u003e\n\n\u003cp\u003eA low NAD⁺\/NADH ratio indicates impaired cellular metabolism metabolism and oxidative stress — your cells are struggling to convert food into energy efficiently. A high ratio alongside low absolute NAD⁺ indicates depletion. Understanding both gives you precision that a single measurement cannot.\u003c\/p\u003e\n\n\u003cdiv class=\"nad-why\"\u003e\n\u003ch3\u003eWhat your results tell you\u003c\/h3\u003e\n\u003cp style=\"margin:0;font-size:0.9em;color:#555;\"\u003eYour report provides your individual NAD⁺ and NADH levels with context on how they relate to your age, metabolism, energy and oxidative stress.
