What Does 300mg Do?
This Niagen product delivers 300 mg of nicotinamide riboside (NR) chloride per serving, a dose used in multiple randomized trials that reliably elevates blood NAD+ levels by 40-100% in middle-aged and older adults.
How does 300mg Niagen NR compare to lower or higher doses in human trials for NAD+ increase?
What specific health outcomes have clinical studies shown for this exact 300mg nicotinamide riboside dose?
Are there any long-term safety data beyond 12-24 months for daily 300mg Niagen use?
