NAD Boosters Explained

High doses of nicotinamide riboside and nicotinamide mononucleotide show promise in raising NAD levels across various tissues, though their ability to cross the blood-brain barrier is limited. Direct NAD injections may offer benefits, particularly for the brain and heart, despite challenges in bioavailability and transport mechanisms. Exploring intravenous NAD delivery could unlock new avenues for enhancing NAD levels in other tissues, warranting further investigation.
