In a deep-dive on the crowded nitric oxide supplement market, biohacking authority Dave Asprey breaks down why most N.O. products on shelves fail to deliver. He explains nitric oxide’s essential role in regulating blood flow, mobilizing stem cells, and powering mitochondrial energy production — and why declining nitric oxide production with age, known as endothelial dysfunction, is tied to many of the health challenges that come with aging.
Asprey walks through the four main categories of nitric oxide supplements on the market: L-arginine/L-citrulline products, beetroot-based supplements, nitrate-based capsules, and N.O. gas-producing products. He points out the shortfalls of the first three — from the body already having sufficient arginine to insufficient nitrate levels in most beetroot products to the fact that oral bacteria disrupted by antiseptic mouthwash can prevent nitrate conversion in roughly two-thirds of people. Products that generate nitric oxide gas directly, he explains, sidestep all of these limitations since they don’t depend on the body’s own conversion pathways or oral microbiome.
Asprey names Pneuma Nitric Oxide’s “Nutriceuticals” as his personal choice in this category, citing their research backing and effective N.O. gas production across lozenge, powder, and topical formats. He recommends N1o1.com for anyone looking to move beyond less effective beetroot powders and amino acid supplements.
