Can Not Stomach It

I usually have had good reviews with all the products offered at National Nutrition but I seem to have a bad reaction with Naturopathic Labs NAC. I bought it some time ago and never felt well taking it so I stopped it. Then forgetting what happened the first time round, I started to take it again reviewing all the benefits of NAC I thought I must need it!
But I have found I get nauseous, gas and diahrea and numbness in the lips. I have been taking 2 with a meal. I don't even want to drop it down and try taking only one as this feeling, I don't want another day of it. In good faith I can not recommend this product as this sick feeling has happened to me twice!

My Everyday Helper

I and my family have been taking NAC since 2017, and recently I found this product in particular. I think it's the best value for the money, excellent quality, and to tell you honestly, when the lockdowns started and next few years I felt particularly happy about having NAC as a supplement. It boosts immune system, helps to recover from colds/flu really fast, and elevates the overall level of energy. All my friends use it, and find it helpful!

GREAT PRODUCT!

This is an excellent product that my husband and I have been using since 2020 when Covid happened. We believe it kept us healthy lung wise, during Covid and beyond.

Immunity Builder

I took this product through Covid and at the beginning of flu season. It has been an great product to take in conjunction with other health supplements to ensure I do not get any respiratory illness. It is also a good product for your dog/s.

More Info

What Is N Acetyl Cysteine?

Aging is a natural part of life that can go smoothly with the help of NAC ...

N-acetyl cysteine (NAC) is a derivative of the amino acid L-cysteine and is a more stable form of this amino acid for supplementation. NAC is a precursor to the important antioxidant, glutathione. glutathione works in the liver to change chemicals and metabolic byproducts into harmless substances for excretion from the body. NAC is also an antioxidant in its own right. It detoxifies heavy metals like mercury, cadmium, and lead.

N Acetyl Cysteine Benefits

It protects all cells of the body from damage due to aging, helps immune cells kill invading microbes (especially viruses) and stops cells from being harmed by radiation and chemotherapy. NAC is recommended by natural health practitioners for conditions such as frequent colds and flu, asthma, bronchitis, acetaminophen toxicity, heavy metal toxicity, low immunity and decreased liver functioning. Supplementation of NAC has been shown to improve the body’s glutathione levels.

NAC is available as an encapsulated powder. Large NAC doses may cause diarrhea. NAC may inactivate some antibiotics and insulin.

How To Take NAC

Adults can take 1 capsule 1-2 times per day. Take with a protein-containing meal. Or follow labelling directions or the direction of your health care practitioner.
