Cacao-derived flavanol that inhibits myostatin and increases follistatin, shifting the balance toward muscle growth. Also stimulates mitochondrial biogenesis and nitric oxide production. Improves grip strength and muscle recovery without being anabolic in the traditional sense.
Tart cherry (Prunus cerasus) is rich in anthocyanins (cyanidin-3-glucoside, cyanidin-3-rutinoside) and proanthocyanidins that inhibit COX-1 and COX-2 enzymes (comparable to ibuprofen in in vitro studies), suppress NF-kB-mediated inflammatory signaling, and scavenge reactive oxygen and nitrogen species. Tart cherry also contains natural melatonin (13.5 ng/g) and tryptophan, supporting sleep quality. The anti-inflammatory and antioxidant effects reduce exercise-induced muscle damage (EIMD) markers (CRP, IL-6, creatine kinase) and accelerate recovery of muscle function post-exercise.
