All this is possible with NMN – Nicotinamide Mononucleotide. NMN boosts NAD+, that declines as we age. NAD+ is essential for metabolism, cellular repair, mitochondrial regeneration, and resist DNA damage, but is an unstable compound which cannot be taken orally. Longiva – Liposomal NMN from BIOM – uses nanoliposomal delivery system to enhance NMN absorption. The product is cold shipped to ensure potency, quality and purity.
