Cardiologist-Formulated RHYTHM NMN Adds 500mg Dose of Setria Glutathione
A new NAD+ supplement, RHYTHM NMN, has entered the market featuring a 500 mg dose of Setria Glutathione, a concentration chosen by the brand's co-founding cardiologist. By prioritizing this specific ingredient, the supplement moves away from standard industry practices that often treat glutathione as a minor, label-only inclusion.

Developed by The Rhythm Line, the formula moves beyond the single-ingredient focus typical of many NAD+ products. Each serving combines 500 mg of NMN with 500 mg of Setria Glutathione, alongside CoQ10, PQQ, trans-resveratrol, vitamin D3, and BioPerine. The brand aims to address consumer demand for cellular health support while maintaining full transparency, disclosing every ingredient and dosage on the label without the use of proprietary blends.
Katie Emerson, Senior Manager of Scientific Affairs at Kyowa Hakko USA, noted that the inclusion of glutathione at a clinically meaningful level reflects a shift in how formulators approach cellular defense. The product is manufactured in a cGMP facility in the United States and undergoes third-party testing for potency and purity via Eurofins. RHYTHM NMN is currently available online and through Amazon, retailing at $69 for a 30-serving supply.
