Micronutrients & recovery
Upregulation of SIRT1 activity via STACs or NAD+ boosters (NR, NMN) protects against cardiovascular aging phenotypes including endothelial dysfunction, atherosclerosis, and ischemia-reperfusion injury by modulating transcription factors and antioxidant pathways.
Current research suggests that maintaining NAD+ levels and sirtuin activity may support cardiovascular health and delay age-related decline. While human trials are ongoing, strategies that naturally support NAD+ (like exercise and lean diets) are supported by this mechanism. Be cautious of unproven high-dose supplements, as excessive SIRT1 activation in certain contexts (like high-fat diets) may have adverse effects on lipid metabolism.
Activation of sirtuins or nicotinamide adenine dinucleotide repletion induces angiogenesis, insulin sensitivity, and other health benefits in a wide range of age-related cardiovascular and metabolic disease models.
Why this rating
Evidence is primarily from animal models (mice, rats, yeast) and in vitro studies; human trials are noted as 'in progress' with 'promise' but no definitive clinical data provided.
