NMNH (Nicotinamide Mononucleotide Hydride) delivers next-generation support for energy, cellular repair, and healthy ageing by driving a 10x increase in NAD+ (Nicotinamide Adenine Dinucleotide) levels, an essential molecule that naturally declines with age. Unlike standard NMN, NMNH remains active for up to 20 hours, helping the body sustain optimal NAD+ levels throughout the day. This supports mitochondrial function, which plays a key role in maintaining consistent energy and cellular resilience.
By increasing NAD+ in five key organs, the brain, heart, liver, kidneys, and muscles, NMNH promotes healthy ageing and helps protect against age-related decline. It supports brain function by fuelling neuronal energy production, which may improve memory, focus, and clarity. The patented crystalline form of NMNH ensures purity, stability, and ease of formulation, offering a reliable way to stay energised, sharp, and balanced.
What sets this NMNH apart is its patent-pending crystalline form, which ensures superior stability, purity, and safety compared to standard versions. This advanced formulation offers consistent and extended support for mitochondrial function, helping the body sustain energy levels and mental focus throughout the day. It also enhances cardiovascular health by supporting optimal blood flow while promoting sharper cognitive function through improved neuronal energy production. By contributing to balanced sleep patterns and metabolic health, this form of NMNH supports a more energised, focused, and well-rounded approach to daily wellbeing.
