Notably, the deletion of Slc7a11 (which encodes xCT) in animals results in viable offspring 15 , which suggests that tissues (and potentially tumours) can obtain cysteine from another origin

Some suggest that supplementing with N-acetylcysteine (NAC, or whey) may be more effective
Study Supports cognition & physical performance The same randomized controlled trial also reported improvements in memory, executive function, gait speed, and muscle strength in older adults taking GlyNAC, pointing to broad benefits in both brain and body performance.Study Reduces inflammation & improves insulin resistance Additional evidence suggests that GlyNAC lowers inflammatory markers and improves insulin sensitivity, two factors closely linked with metabolic health and long-term disease prevention
Therefore, they provide a compelling technological and mechanistic precedent
For example, in experimental arthritis, it has been demonstrated that the systemic administration of ACs protected mice from autoimmune arthritis by inducing regulatory B cells, thereby restraining inflammatory responses [41]
