Niagen Bioscience launches Niagen Plus telehealth platform, unveiling Niagen At-Home Injection Kit offering

"With this launch, we are expanding access to Niagen through a clinician-directed telehealth model designed around quality, convenience, and clinical oversight," said Rob Fried, Chief Executive Officer of Niagen Bioscience. "We are introducing a new way for eligible patients to access pharmaceutical-grade Niagen from home while staying grounded in the scientific rigor, quality standards, and disciplined approach that define Niagen Bioscience."

This clinician-directed telehealth program guides patients through an online medical intake and consultation with a licensed provider. Eligible patients may be prescribed the Niagen At-Home Injection Kit, a new prescription-only offering featuring Niagen, the most efficient, effective, high-quality NAD+ support for cellular health and overall vitality. If prescribed, the complete kit is dispensed by a licensed 503A pharmacy and shipped directly to the patient's door.

In 2025, the U.S. injectable industry was valued at USD 223.6 billion, with sales projected to grow at approximately 6.8% CAGR through 2035, according to Future Market Insights. In the U.S., the longevity market is projected to grow from USD 9.16 billion in 2025 to USD 20.17 billion by 2035, a CAGR of 8.34%, according to SNS Insider.

"What I find compelling here is the emphasis on process and quality," said Dr. Chris Meletis, Former Dean and Chief Medical Officer of National College of Natural Medicine (NCNM) and advisor to Niagen Bioscience. "This is not a casual direct-to-consumer purchase. It is a clinician-directed telehealth program designed to evaluate eligibility and, when appropriate, provide prescription access to pharmaceutical-grade Niagen in an at-home format."

The Niagen At-Home Injection Kit is designed for subcutaneous administration and includes a sterile 500 mg vial of Niagen powder, bacteriostatic water for reconstitution, injection syringes, mixing syringe and needle for reconstitution, alcohol prep pads, and step-by-step instructions accessible by a QR code. The compounded kit is manufactured under cGMP standards using pharmaceutical-grade components and follows clinician-directed 50 mg or 100 mg dosing protocols, as prescribed.

In a clinical safety trial, the Niagen At-Home Injection Kit was generally considered safe and well-tolerated, with no significant adverse effects reported at 50 mg/mL and 100 mg/mL dosages over the course of the study. By bypassing gut metabolism, injectable administration offers a more direct delivery pathway for Niagen, with preclinical models suggesting the potential for greater tissue availability.
