Life Extension Pterostilbene Review

Life Extension Pterostilbene is a dietary supplement featuring pterostilbene, a naturally occurring polyphenol primarily found in blueberries and, in smaller quantities, in grapes. This compound is a stilbenoid, sharing a structural resemblance to resveratrol, another well-known polyphenol. However, pterostilbene distinguishes itself with superior oral bioavailability and a longer half-life in the bloodstream, allowing for enhanced cellular uptake and potentially greater physiological benefits. The supplement is designed to activate key longevity pathways within the body, mimicking many of the beneficial effects associated with calorie restriction. Pterostilbene achieves this by influencing three major molecular pathways linked to aging: mTOR, AMPK, and sirtuins. Sirtuins, or silent information regulators (SIR), are crucial anti-aging molecules that regulate gene expression, cellular aging, DNA repair mechanisms, metabolism, and apoptosis (programmed cell death). By modulating sirtuin activity, pterostilbene helps maintain cellular integrity and function, including supporting telomere length, which is a critical factor in cellular longevity. Beyond its role in longevity pathways, pterostilbene acts as a potent antioxidant, actively combating oxidative stress and preventing the accumulation of age-related cellular waste products, such as lipofuscin. This antioxidative capacity is vital for protecting cells from damage and supporting overall cellular health. Furthermore, pterostilbene exhibits significant anti-inflammatory properties, capable of suppressing inflammatory pathways by inhibiting molecules like NF-Kb and reducing various inflammatory markers. Research indicates that pterostilbene supports a range of health benefits, including cardiovascular health, by protecting against heart disease and the effects of oxidized low-density lipoprotein on blood vessel cells. It also contributes to maintaining healthy glucose levels and metabolic balance. In the realm of neurological health, preclinical studies suggest neuroprotective effects, with potential to improve cognitive ability, enhance brain plasticity, and offer protection against neurodegenerative conditions like Alzheimer's disease by reducing inflammation, oxidative stress, and neuronal damage in animal models. The compound has also been investigated for its potential role as an antitumor agent and in cancer prevention. Life Extension's Pterostilbene utilizes high-purity pterostilbene, often featuring patented forms like pTeroPure, to ensure quality and efficacy.

Study, Trial or Testing Result Summary

MembersHuman studies

Only two human studies exist, and both gave pterostilbene together with nicotinamide riboside, so the of pterostilbene alone cannot be separated out. In 24 hospital patients with sudden kidney injury, the combination taken twice daily for 2 days blood levels of a key cell energy molecule by 37 percent after 48 hours, while levels fell by 50 percent on placebo. …

MembersWhat our biohacker panel says

Three of them lean on : one says it lacks proof in people and that exercise and muscle have far evidence, and another says there is evidence it extends lifespan and that it may LDL cholesterol unless taken with grape seed extract. Those who like it, including one who switched from resveratrol and another who prefers it, say it is absorbed than resveratrol so is needed, and one uses it in a blend for mitochondria and mental energy. …
