RevitalAge™ Ultra is a scientifically researched combination of acetyl-l-carnitine (ALC) and alpha lipoic acid (ALA) offered with antioxidant and mitochondrial support cofactors. It promotes healthy aging through mechanisms involving gene expression, mitochondrial function, cellular energy production and antioxidant protection. Specifically, alpha lipoic acid, acetyl-l-carnitine and resveratrol support mitochondria synthesis by promoting healthy activity of the key enzyme AMP kinase (AMPK). Nicotinamide riboside chloride (NR) is a precursor of nicotinamide adenine dinucleotide (NAD+), a key driver of cellular energy production. Some evidence suggests that NAD+ declines with age in humans. NAD+ activates SIRT1, an epigenetic switch that regulates metabolism, mitochondrial biogenesis, cellular energy production and cellular longevity. Higher NAD+ levels are associated with healthy mitochondrial function. Resveratrol supports SIRT1 activity and mitochondrial function. pTeroPure™ is pure, clinically researched pterostilbene, the methylated analog of resveratrol. It may provide additional antioxidant support when combined with resveratrol. CoQ10 offers antioxidant protection from free radicals that contribute to cellular aging. Preclinical research on aging has revealed the patented combination of acetyl-l-carnitine (ALC), alpha lipoic acid (ALA) and biotin can promote cellular longevity.
