Pilot Human Study Supports Safety of NAD+ IV and NR IV Infusions

A Stanford study supports the short-term safety of NAD+ and NR infusion therapies, and participants who received NR infusions exhibited significantly lower HbA1c (a blood test that reflects average blood sugar over two to three months).
