Fatty15 is a daily supplement built around C15:0, a odd-chain saturated fatty acid the brand says strengthens cell membranes and slows cellular aging. The refill packs three 30-count packets of capsules; the glass bottle is sold separately. It is aimed at adults who want a single-ingredient longevity and metabolic supplement rather than a multivitamin blend. The pitch rests on published C15:0 research and user reports of better sleep, mood and energy, though those benefits are self-reported and not guaranteed.
