What Is NMN?

NMN, or nicotinamide mononucleotide, is a vitamin B3 derivative that serves as a precursor to NAD+ (nicotinamide adenine dinucleotide), a coenzyme essential for cellular energy production, DNA repair, and metabolic regulation. As NAD+ levels decline with age (up to 50% by age 50), NMN helps restore them, supporting anti-aging processes. Unlike direct NAD+ supplements, which are poorly absorbed, NMN is more bioavailable and converts efficiently in the body. Research, such as a 2021 trial, shows NMN (250-500mg daily) improved muscle insulin sensitivity and endurance in older adults, suggesting benefits for metabolism and vitality. In the UK, with the supplements market valued at over £1.5 billion in 2025, NMN is a popular natural choice – but complementary to diet and exercise, not a cure. SellHealth UK’s Rejuve® NMN range, with 99.93%+ purity, is formulated to maximise these effects.

Benefits of NMN Supplements

Based on recent studies, NMN offers several potential benefits:

• Increased Cellular Energy: NMN raises NAD+ levels, improving mitochondrial function and reducing fatigue.
• Improved Metabolic Health: Enhances insulin sensitivity and glucose regulation, aiding weight management.
• Cardiovascular Support: May reduce blood pressure and cholesterol in at-risk groups.
• Better Sleep and Reduced Fatigue: Afternoon dosing improves sleep quality and daytime function.
• Enhanced Physical Performance: Increases walking distance and endurance in middle-aged adults.
• Potential Neuroprotection: Early research suggests benefits for cognitive health and neurodegenerative conditions.

SellHealth UK’s Rejuve® NMN range amplifies these with high purity and flexible formats.
