As long as suggested serving sizes are adhered to, this product is considered safe. However, if you are taking nitroglycerin or any medications that affect the heart, a medical professional should be consulted beforehand. It is also possible that NAC may block insulin, which means that diabetics are cautioned from taking this supplement.

If taking more than the recommended amount, side effects such as vomiting, nausea, headache and gastrointestinal pains may be experienced from use of this supplement. However, these side effects are quite rare. Taking a larger amount of one supplement may cause the absorption of other supplements to be less effective; it is important to supplement other minerals such as copper and zinc to make up for what is being lost.

This is a capsuled product.

Customer Reviews

Eyes and Joints
I ordered N-Acetyl D-GlucosamIne (NAG) in powder form so that I can have the option of using it in a powder form or put some in capsules of which I purchased with my order. I also purchased N-Acetyl Glutamine with this order. I looked everywhere for NAG but could only find it here (BulkSuppplement). Everywhere else Glucosamine HCl is sold. Glucosamine HCl first passes through the liver and gets converted into glucose by the hepatocytes. Therefore, you would have to take mega doses of Glucosamine HCl to bypass the liver and get to the target organs. I am taking it for joints and eyes as NAG gets past the liver and to the eyes and joints for vitreous humor (eyes) and synovial fluid (joints). NAG is a precursor of these vital fluids. Thank you BulkSupplements, Davi Gonzales, M.S., Ph.D., Endocrinology.*

So much better than other brand I tried
I had a reaction to another brand and switched to Bulk Supplements. The other brand had several fillers.

Both my husband and I have benefitted from this NAC. It cut my depression and anxiety by at least 75%, and it has caused my hair to start growing in again. I know this sounds too good to be true, but NAC apparently has multiple benefits. My adult acne is almost cleared, as well. I know how it sounds, but this is what this product does.

My husband has not seen new hair growth, but he has more energy and feels less tired at the end of the day. For him, that is significant.*

breathing issues
I purchased this NAC in capsule form to give to my horse that has developed lung problems. Similar to COPD. He is breathing much better. I ran out a while back and he noticeably got worse. So I reordered and don't expect to go without again.*

Economical Capsule Form
I had been using NAC powder to help with lung function but it is very sour so I was glad to find an economical capsule form*

I purchased this because I have Food sensitivities and allergies. This helps me so much and helps prevent and or lessen reactions to the things I am allergic to.*

Pure NAC
This is probably the purest form of NAC you can buy. I simply love Bulk Supplements since there are no unnecessary fillers and you really get to see the product at work. I highly recommend!!*
