N-Acetyl Cysteine
7Nutrition - NAC 150g – 17.00 €N-Acetyl Cysteine (NAC) is a powerful antioxidant, a precursor to glutathione – one of the most important antioxidants in the body. Doses of 600-1200 mg daily are commonly used to support cellular defense against oxidative stress, especially intensely after workouts. NAC is known for its mucolytic properties, supporting respiratory function, which is important for athletes exposed to polluted air or suffering from respiratory problems. Research published in the Journal of the International Society of Sports Nutrition highlights NAC's role in reducing muscle fatigue and improving recovery after extreme physical exertion.
NAC supports liver detoxification, which is crucial for athletes using various supplements or subjected to metabolic stress. It can also play a role in regulating dopamine levels, which is associated with mood and motivation. NAC intake is particularly beneficial during periods of intense training when the body is subjected to increased oxidative stress and needs effective recovery. Studies show that glutathione levels can drop by up to 30% after heavy physical exertion, making NAC supplementation important.

FAQ
What exactly is N-acetylcysteine (NAC) and who should take it?
NAC is a form of the amino acid cysteine. It's a powerful antioxidant that helps your body produce its own master antioxidant, glutathione. It's a great choice for anyone looking to support their immune system, as well as lung and liver health—especially if you live in a polluted city or are a smoker.
How and when should I take NAC? Daily? With or without food?
A typical daily dose is between 600mg and 1200mg, split into two servings. For best absorption, try taking it on an empty stomach, like once in the morning and again in the afternoon. If you have a sensitive stomach, though, it's perfectly fine to take it with a meal.
What are the real-world benefits of taking N-acetylcysteine?
Beyond its general antioxidant power, NAC is well-known for its respiratory benefits, as it helps thin mucus. It also supports the body's natural detoxification processes in the liver and can even help reduce fatigue after a tough workout.
Can I stack NAC with other supplements? Are there any side effects?
Absolutely. NAC works great with other antioxidants like Vitamin C, Vitamin E, and Selenium to boost its effects. Side effects are rare at the recommended dosages, but some people might experience mild stomach upset. As with any supplement, it's always a smart idea to check with your doctor if you're taking any prescription medications.
