* This formula is designed to relieve occasional mental and physical fatigue by supporting healthy cognition, promoting muscle energy, boosting immune defense and neutralizing free radicals. The role of acetyl-l-carnitine in neurotransmitter function accounts for its ability to relieve mental fatigue, promote memory, support mental clarity and promote emotional well-being. In an exploratory open label, randomized study, acetyl-l-carnitine supplementation demonstrated statistically significant beneficial support for mental fatigue. Its capacity to encourage ATP production also makes it a crucial component for energizing muscle. Malic acid further promotes energy production by enhancing ATP synthesis, which is essential for proper muscle function. Magnesium also plays a key role in cellular energy metabolism. Ashwagandha is highly revered for promoting energy, vitality and immune defense according to traditional use. In animal models of fatigue, it helps stimulate antioxidant defenses. N-acetyl-cysteine (NAC), alpha lipoic acid and selenium also help diminish the impact of oxidative stress in fatigue, in part by supporting glutathione production. Furthermore, they play an important role in mitochondrial function and protection. Nutrients like zinc and vitamin D are additional cofactors that may support individuals experiencing occasional fatigue.
