Initially it was believed that the use of BCAA is perfectly safe and that it has no ill effects on the body, but  like with any food supplement there is always the possibility of side effects. Plus the fact that everyone is not the same and we all might have different reactions to the supplement. Further research and reports of people who have been using BCAAs have confirmed that its use does bring in some side effects.

For some people the use of BCAA can cause to feel fatigue and some have reported loss in body coordination. These effects are the reason why it is not advised that people use BCAAs before an activity like driving where coordination is required. People who are suffering from particular diseases are not advised to take BCAA. Patients who suffer from Lou Gehrig’s disease or amyotrophic lateral sclerosis can suffer from lung failure if BCAA is ingested into their body. These are just some of the known BCAA side effects.

Along with glutamic acid and glycine, N-Acetyl Cysteine (NAC) is a direct precursor to the powerful free radical scavenger glutathione. Glutathione is present in every living cell in the body. Blood levels of glutathione are diminished during and following any anaerobic event i.e. intense exercise.

In addition to protecting the body from oxidative damage resulting from normal metabolism and environmental toxins, NAC has shown positive effects on liver function, protecting the liver from heavy metals like lead and mercury.

Side effects that can occur with NAC use at high doses include nausea, headache, vomiting, dizziness, and abdominal pain.

NAC may lead to the excretion of zinc and copper – metals required for proper hormone function, so be sure to supplement with these minerals if you use NAC.

NAC tolerance is generally excellent in most users and NAC is not known to be contraindicated with any dietary supplements or prescription drug products.

Glutathione helps the body fight almost any disease, because it is a powerful antioxidant that helps maintain cellular health and helps prevent oxidative stress. Glutathione has been heavily researched, and the findings on this substance have been nothing short of amazing.

Glutathione is essential for immune system function and muscle growth, and any athlete who is glutathione deficient will suffer from decreased performance and a lack of muscle growth.

Hard training is known to deplete glutathione levels. Thus, the hard-training athlete can benefit especially from glutathione supplementation and the enhanced recovery and muscle building results seen from its use.

Many published studies show that garlic, selenium, alpha-lipoic acid, L-cysteine, and N-acetyl-cysteine can boost cellular glutathione levels.

Dietary sources of glutathione and glutathione precursors include meats, fish. fruits, vegetables, avocado, walnuts and asparagus. Glutathione precursors are also found in whey protein concentrate.
