Its acetylated structure enhances absorption compared to L-carnitine supplements, with studies demonstrating a 43% increase in circulating ALCAR concentrations following daily oral doses of 2 g [12]
Because most dietary carnitine comes from animal products, vegetarians and vegans typically have lower baseline carnitine levels than habitual meat-eaters a detail that turns out to matter for who is likely to benefit from supplementation
27 These modalities influence ion channel activity, increasing intracellular calcium levels, which are crucial for activating downstream signaling pathways such as calcineurin/NFAT, leading to increased protein synthesis, growth factor production, and accelerated tissue repair
