I tried Pure Encapsulations NAC + Glycine Powder, and the main thing to know is that the peach-ginger flavor is quite tart. The powder smelled fruity when I opened it, but I made the mistake of putting a scoop directly in my mouth. It tasted intensely sour, almost like sucking on a lemon. Based on that experience, I recommend mixing it with water rather than taking the powder directly.
The seller listing directs users to mix one scoop with 8 ounces of water, take it between meals, or follow the directions of a health professional. It also states that each serving provides 1,800 mg of N-acetyl-L-cysteine and glycine. Those are listing details, not amounts I independently measured or verified.
In my glass, the powder mixed fairly easily. It occasionally needed another stir, but after mixing I did not see powder sitting at the bottom. Adding enough water made the sourness much more manageable. I would compare the finished drink to a fruity lemonade in terms of tartness.
Although the label describes the flavor as natural peach-ginger, I did not immediately identify either flavor. Before rereading the container, I thought it tasted more like orange. The flavor came across to me mainly as fruity and sour rather than distinctly peach or ginger.
The product label identifies it as gluten-free, non-GMO, and hypoallergenic. The seller listing also says it is free from common allergens, GMOs, and artificial or unnecessary ingredients. I did not independently verify those formulation claims.
I take this supplement under a doctor's supervision. My hands-on observations here are limited to the taste and how it mixed in water. I did not test the seller's claims about immune support, respiratory health, antioxidant support, detoxification, or glutathione synthesis.
Overall, I like the product. The powder mixed well for me, and the flavor was acceptable once diluted with enough water. Anyone sensitive to tart drinks should pay particular attention to the water ratio and follow the label or guidance from a health professional.
