INCOGNITO

not interested in filling out personal info but been a fan of NOW Brand for a lot of years and & also impressed that more powders are available. I would like to see your company find ways to recycle your containers, there is no reason to have only one use and into the plastic pollution in the overflowing Earth is choking in it.

Sciatica Nerve Pain Relief

When I pulled a muscle in my back along with a pinched sciatica nerve I took 1/2 tsp of the powdered Now brand NAC product...result...in 3 weeks I was back to 90%...4 weeks 100%. Do the research on NAC and skeletal/nerve pain. It is hard to swallow but back pain is worse. Tastes like sulfer smells. No pain, no gain! NAC

Concerned

Not sure how they get 188 servings per 4 oz package, at 1/4 tsp being a serving. Someone's math is off. I capsuled my usual 1/4 tsp into 00 capsules, and got no where near 188 capsules and my bottle is almost gone. Also, shocked when I broke the two safely seals and got ZERO sulfur odor coming out of this product. My normal brand of NAC powder has a very strong sulfur odor when opening.
