Deep dives
Stopped Supplements Review: Spermidine
Spermidine, a supplement popular for its touted benefits on autophagy and longevity, lacks solid evidence for its efficacy. Human trials have not shown significant longevity benefits from spermidine supplements, with studies indicating minimal impact on blood levels and cognitive function. Instead of supplements, focusing on dietary sources like wheat germ, cheeses, and vegetables is suggested for better spermidine intake.
Calcium alpha-ketoglutarate, a trending supplement with possible health benefits related to energy production and aging, lacks substantial evidence for regular use. While a study showed reduced biological age scores in humans, the costly supplement awaits further research to confirm its longevity effects. Until more data emerges, cautious consideration of calcium alpha-ketoglutarate consumption remains prudent.
Stopped Supplements Review: Chocesterone
Chocesterone, an insect steroid hormone supplement claiming muscle growth benefits, falls short of significant scientific backing. Despite slight observed strength improvements, human trials remain inconclusive about its muscle growth effectiveness. Due to its theoretical nature and higher cost, chocesterone intake is currently viewed as speculative.
Stopped Supplements Review: Alpha GPC
Alpha GPC, a cholinergic supplement with potential nootropic effects, can support brain function and neurodegeneration prevention. While offering cognitive benefits, obtaining choline from dietary sources like eggs is favored over supplements for most individuals. Adequate choline intake, especially from varied diets, contributes to brain health without the necessity of additional nootropic agents.
