Designs for Sport NAC 900

Hard training blocks leave you more fatigued than a single night of rest can fix. Part of that comes down to oxidative stress building up faster than your body can neutralize it, and neutralizing it depends on one raw material your body can only produce so much of on its own.

Designs for Sport's NAC 900 is built to hand your cells more of that raw material directly, delivering 900 mg of N-acetyl-L-cysteine in a single daily capsule.

Fuels Your Body's Own Antioxidant Defense - NAC 900 supplies the cysteine your body needs to keep producing glutathione, the antioxidant your cells rely on most, so your natural defenses keep pace with training instead of falling behind.

Supports Performance When Training Gets Hard - By feeding the same pathway that keeps oxidative stress in check, NAC 900 supports exercise performance during your hardest training blocks, not only the easy ones.

Backs Recovery Between Sessions - The same antioxidant support that helps during a workout keeps working afterward, giving your body what it needs to recover between one hard session and the next.

Glutathione is built from three amino acids, glycine, glutamine, and cysteine, and cysteine is the one your body runs short of first. Taking glutathione itself as a supplement runs into a problem, since the tripeptide breaks apart in your gut before much of it reaches your cells. NAC sidesteps that. It's a small, stable form of cysteine that absorbs efficiently and hands your cells the exact building block they need to keep glutathione production running, the same antioxidant system that also backs your respiratory and immune function during heavy training.
