I think the soluble state is better for my purposes, which are focussed on helping to relieve excessive mucous caused by allergic reaction.
I guessing I'm probably using the NAC product for a different reasons than the normal customers. I've recently read that taking NAC can promote a longer healthy life span. So am giving it a try. Not sure how I'm going to prove one way or another if it is doing anything but happy I'm taking it all the same. Product, as described, arrived very quickly and with no hassle
This supplement is great, I noticed a difference as soon as I started using the product. I'm very happy with it :)
