NAD+ Nasal Spray

• 53/100 science score
• $100 price
• Promoted by Gary Brecka

Overview

NAD+ nasal spray scores low due to absence of human RCTs supporting claims, relying on one rat ischemia study (PubMed PMID 17127275) showing brain NAD+ increase at 10 mg/kg (~700 mg human equivalent), far exceeding typical 30-120 mg/day doses. Oral NMN boosts NAD+ (e.g., 300-900 mg/day in trials) but fails to improve muscle strength, insulin sensitivity, or aging markers in meta-analyses (Examine.com). Safety docked for FDA unapproved status (warning letter to AliveByNature for disease claims).

Key strengths

• Convenient needle-free delivery with potential fast brain absorption (animal evidence)
• Minimal reported side effects
• May boost cellular NAD+ levels

Our analysis

NAD+ nasal spray lacks human evidence for claimed benefits and is not FDA-approved. Opt for well-studied oral NMN/NR precursors instead. Avoid until clinical trials confirm efficacy.
