Bad combination - too much selenium in this NAC product

Posted by Reviewer2498328 on Mar 04, 2009

I take this for HIV, 3 capsules per day. This adds up to 75 mcg selenium. When taking this in combination with NOW's own Adam men's multi-vitamin, which contains the recommended 200 mcg selenium, one gets 275 mcg selenium. This is excessive. I had my blood selenium level checked, and it was elevated. I chose to continue the Adam multi but stop this NOW NAC . I switched to the Jarrow NAC which doesn't have selenium.

Can Breathe with through my nose again.

Posted by Reviewer3356710 on Mar 24, 2011

It seems like I always have at least one side of my nose to where I couldnt breathe through, but after taking the NAC with Vitamin C it cleared that up like within a couple of hours. The only problem is that they make my head feel like of weird. Not sure why they do, but they do. But they definately help to breathe better.

OK, I guess?

It's difficult to tell i this had any effect. Maybe it worked, maybe it didn't. I've got asthma and somewhat chronic sinus problems, and I didn't notice that much improvement when using NAC from this brand. I've tried different brands like Solgar and felt a better response. It should be the same substance though... Maybe it hasn't noticeably helped me with my lungs, at least yet (3 months), but works possibly better as a detox agent? I'll probably buy Solgar next time to see if there really is a difference.

Capsule is a pain

Posted by Reviewer3253087 on Apr 15, 2012

The product in the capsule is fine; the capsule is a pain in the throat. This product capsule often becomes caught in my throat unless I take it with a mouth full of food. If you take it with water, let it soak in your mouth for 1/2 a minute first. NAC really burns in the throat so make sure it goes down the first time.

for bipolar disorder

Posted by Reviewer1864518 on Mar 05, 2012

I bought this product because I had read about some small studies in Australia that showed it might have some efficacy for bipolar disorder. I don't think I have been taking it long enough to say whether it is helpful or not in that regard. I will update when I know more.
