Can N-Acetyl Cysteine funct..

i bought N-Acetyl Cysteine thinking it was the same as glutathione. would i have any problems taking it in a regular basis [side effects]? i'm using glutathione to whiten my skin. will it do the same for me?

Many females with darker skins,esp in E and SE Asia, use or abuse some drugs to get whiter. But I tell you the body's color is genetically determined and drugs usually have just a temporary effect on skin's color.

One study reported that 19% of people taking NAC orally experienced nausea, vomiting, headache, dry mouth, dizziness, or abdominal pain.

Although a great deal of research has shown that NAC has antioxidant activity, one small study found that daily amounts of 1.2 grams or more could lead to increased oxidative stress. Extremely large amounts of cysteine, the amino acid from which NAC is derived, may be toxic to nerve cells in rats.

NAC may increase urinary zinc excretion. Therefore, supplemental zinc and copper should be added.
