The NADMED measurement is significantly more efficient than other NAD measurements on the market, as NADMED can separate all four NAD forms from each other and measure their quantities accurately. Traditional NAD measurement methods are either expensive, slow, or inaccurate. The NADMED method offers a fast, accurate, and cost-effective way to measure all four NAD forms (NAD+, NADH, NADP+, NADPH) as well as glutathiones.
