What is NMN? A Doctor's Guide to Nicotinamide Mononucleotide

NMN — nicotinamide mononucleotide — is a molecule the body can use in pathways that produce NAD+, a coenzyme involved in cellular energy metabolism and many other biochemical processes.

That simple relationship is why NMN has attracted so much interest in healthy-ageing research. It is also why it is important to distinguish the established biology from the much bigger claims sometimes made about supplements.

What does NMN do?

NMN is an NAD+ precursor. Human studies have shown that oral NMN can alter NAD-related biomarkers, which tells us that it is biologically active. Research is continuing into whether those changes produce meaningful long-term benefits in areas such as physical function, metabolic health and healthy ageing.

What we do not have is evidence that taking NMN reverses ageing, guarantees more energy or prevents disease.

What should you look for in an NMN supplement?

• A clearly stated daily serving. Compare the amount of β-NMN in the recommended daily serving, not just the number of capsules in the bottle.
• Independent testing. Look for transparent quality information and Certificates of Analysis where available.
• A sensible formula. Decide whether you want NMN alone or additional ingredients such as trans-resveratrol.
• Realistic claims. Be cautious of brands promising age reversal or disease prevention.
• Transparent long-term cost. Compare one-off, subscription and annual prices.

Little Ox NMN Pure vs NMN Plus

NMN Pure provides a 500mg daily serving of β-NMN and is the simpler, lower-cost option.

NMN Plus provides the same 500mg daily serving of β-NMN and adds trans-resveratrol.

How much does Little Ox NMN cost?

NMN Pure is currently £7.99 one-off and NMN Plus £9.99 one-off. Both have a monthly Subscribe & Save plan at 15% off. Annual options are also available for customers who prefer to buy a longer supply upfront.
