Rejuvenate is a single-origin Bolivian coffee from 1775 that carries 1g of calcium alpha-ketoglutarate (Ca-AKG) per two cups brewed. The coffee itself is certified organic and rated 85+ specialty grade, with no fillers, so it brews like ordinary drip, French press or pour-over coffee. Ca-AKG is a compound the body makes on its own and produces less of with age, and the brand cites a study of 1,000mg daily showing an average 8-year drop in biological age on DNA methylation tests. It suits daily coffee drinkers who want a functional add-on without changing their routine; against plain specialty coffee it adds an ingredient, but the evidence is early and the effect builds only with consistent use.

Rejuvenate is a specialty-grade, single-origin Bolivian coffee infused with calcium alpha-ketoglutarate (Ca-AKG). Each two cups brewed contains 1 g of Ca-AKG. The only ingredients are Ca-AKG and coffee, with no fillers.
Ca-AKG plays a role in cellular energy production and collagen synthesis. The body produces it naturally. A study using 1,000 mg of Ca-AKG daily for an average of seven months showed an average 8-year reduction in biological age, measured by DNA methylation testing.
It brews like regular coffee, using drip, French press, or pour-over methods. Its effects build with continued use.
