Administration of a novel amino acid formulation (AXA2678) containing essential and non-essential amino acids, including N-acetylcysteine, attenuates skeletal muscle atrophy and prevents intramuscular fat accumulation during short-term (7-day) limb immobilization in healthy young men.

If you are facing a period of forced inactivity (like a cast or bed rest), standard protein or leucine supplements may not be enough to stop muscle loss. A specific blend of essential and non-essential amino acids, including antioxidants like NAC, appears to protect muscle mass and prevent fat infiltration in the muscle during short-term immobilization. This is not a substitute for movement, but a mitigation strategy.
