This is a keeper

Posted by Reviewer2920500 on Jul 20, 2010

I like this product. I can tell a difference and my husband has Parkinson's and so I think they help him also. He takes it twice a day as this proguct is a percursor to Glutathione which is much needed with this disease.Of course this is not a cure but it helps with slowing down the progression of it.Over all I Like the product better than others.

This does seem to have a detoxing effect. I get lttle back pains around my kdneys and this seems to have disappered since I started taking this.

I'm taking this because my Dr recommended it, along with a few other supplements, but I don't know whether they are all helping, or which individual ones are helping. I am feeling better. Because of the short half life of NAC, I like that this one is a sustained delivery version.

My father was a diabetic, therefore half of my genetic makeup is from him, this makes me a candidate to becoming a diabetic myself. Once a person becomes a diabetic there is no going back. Therefore with very careful diet and living and with the aid of certain preparations I want to delay diabetes as long as possible.

With allergy problems, I'm happy to find a sustained NAC in a good dosage.

Outstanding NAC Formula

Posted by Reviewer2640851 on Feb 02, 2009

There is a lot of good science in this, particularly the sustained release. It really seems to work for me and I recommend it to anyone needing such a supplement.

Read that NAC has absorbtion problems. This formula is supposed to do better.
