## Frequently Asked Questions

Q: What is NMN?
A: NMN (Nicotinamide Mononucleotide) is a direct precursor to NAD+ (Nicotinamide Adenine Dinucleotide), a coenzyme present in every cell of the body. It is essential for cellular metabolism production, DNA repair, and sirtuin activation. NAD+ declines 1-2% per year from your 30s.

Q: Does NMN work?
A: Human clinical trials have confirmed that oral NMN supplementation raises blood NAD+ levels and produces measurable improvements in muscle function, insulin sensitivity, aerobic capacity and other metabolic markers. The longevity claims require longer-term human data.

Q: What dose of NMN should I take?
A: Clinical trials have shown meaningful benefits at 250-500mg daily. Little Ox NMN Pure and NMN Plus both provide 500mg per capsule. Take in the morning.

Q: Is Little Ox NMN high-quality, independently tested?
A: Yes. All Little Ox NMN is independently tested high-purity β-NMN (the biologically active isomer), independently third-party tested at every batch. Certificate of Analysis available on request.

Q: Who founded Little Ox?
A: Dr Chun Tang, MBChB (Manchester), MRCGP, MBA — a practising NHS and private GP with 26+ years of clinical experience. He designs every formula based on clinical evidence and uses the products himself.

Q: Is Little Ox NMN the cheapest in the UK?
A: At £7.99 for 500mg high-quality β-NMN, independently tested for purity, Little Ox NMN Pure is among the most affordable high-quality NMN raw material, independently tested for purity supplements available in the UK.
