NAD⁺ / NAD (Intranasal Spray)
Investigational NAD+ coenzyme, intranasal spray format · Intranasal spray
NAD+ (nicotinamide adenine dinucleotide) is a central coenzyme in mitochondrial energy production, DNA-repair enzyme activity and sirtuin signalling, all of which decline with age. This product presents NAD in an intranasal spray, on the premise of supporting cellular energy and resilience. While NAD+ biology and its precursors are widely studied, controlled human evidence for an intranasal NAD spray specifically is lacking.
Studied use areas
- Mitochondrial energy-metabolism support (research interest)
- DNA-repair and cellular-resilience pathways
- Sirtuin-linked longevity signalling (investigational)
- Cognitive-performance and general vitality frameworks (exploratory)
Safety & status
- Intranasal-spray delivery of NAD is unproven; efficacy and safety are not established in controlled trials
- Use only under physician supervision; not a licensed medicine via EMA or MHRA
- Nasal-route products may cause local irritation and are not appropriate for everyone
⚕ Clinical note: This is educational information only and not medical advice. This NAD intranasal spray is investigational; any use should be individualised and determined by a treating physician under appropriate supervision.
Evidence: Grade D — investigational; NAD+ biology is well established, but the intranasal-spray route has essentially no controlled human efficacy data. · References: Peer-reviewed NAD+ and sirtuin metabolism literature; Clinical studies of NAD+ precursors (e.g. NR/NMN); EMA/MHRA guidance on food-supplement versus medicinal claims
