Does anyone have any warm and fuzzy feelings about taking the supplement NAC on a daily basis for antioxidant and liver support?

Company does...: I bet the company that sells the product has warm and fuzzy feelings. We here at HealthTap don't promote individual products. Nor do most of us promote the use of supplements routinely. It is far better to eat the nutrients you need than take them in the form of a supplement. It is a rare person who actually NEEDS a supplement because of medical circumstances. Helps the company who sells them! ...Read more

Why are supplements of NAC not recommended? Do they pose a threat to health? Or is it just because it is not "FDA approved"?

See http://www.Ncbi.Nlm.Nih.Gov/pmc/articles/pmc436956/ good luck with your condition! ...Read more

Is it safe to take alpa lipoic acid, n-acetyl l-cysteine (nac) and milk thistle when  prescribed quetiapine?  The supplements i take for my liver.

Probably safe: Please speak with your own physician about this first. There are no problems with alpha-lipoic acid or nac and quetiapine, but there's a possible interaction with milk thistle. There's contradictory evidence aboutit increasing, decreasing, or having no effect on the liver enzyme system that processes quetiapine. In 1 human study milk thistle didn't affect these enzymes -- so with caution, ok. ...Read more
