Good brand, but low dose
Verified purchase
Nutricology are well respected and often used by practitioners. The patented blend used in this product is good, but the NAC dosage (200mg) is lower than most other NAC supplements, so I had to double dose. I take at night (when you are supposed to use anti-oxidants) and it has not impacted my sleep.

Feel effect
Verified purchase
I was struggling with allergic reactions. However, I took this tablet only once, and my allergic reactions improved. Taste and quality are ok. The size of the tablet was bigger when compared to the Japanese one. However, I found iHerb product similar to this, so I reordered that one.

I was Googling this combo and have come accres this producer. From the research it seems trusted and quality brand, thats very important as you dont want our antioxidant is adding oxidative stress onto your organization due impurities. I take a dose of one caps a day befre my lunce and add 500mg of NAC in the mornig from a different producer. Its a good composition of ingredients to boost the glutathione

Great product to help boost Glutathione levels within human cells. Glutathione is a vital molecule, designed to help protect cells from damaging, free radical molecules and other chemicals that can damage human tissue, leading to organ tissue damage. I noticed an immediate benefit from using these NAC capsules, as they went to work on clearing up whatever toxins were accumulating inside my cells, from years of stress and occasional drinking and junk food consumption A great supplement based on amino acids used directly within the human body (cysteine, glycine) to make a vital molecule, Glutathione, to protect cells from harmful toxins that accumulate with age 👍

Who Knew
Verified purchase
After i took a test to se all my deficiencies, this was recommended to me. Because of my diet (OMAD) and my age i needed this with a high quality of ingredients. The size could be bigger but it works for me. It has a taste but not bad. To prevent them from going old, keep the moist absorbers in.
