N-acetylcysteine protects cold platelets
We explored the impact of N-acetylcysteine, an antioxidant, on the preservation of cold-stored platelets. The study focused on understanding how this treatment might reduce the harmful effects caused by reactive oxygen species (ROS) generated during cold storage.

Platelet concentrates were categorized into three groups: those stored at room temperature, those kept cold, and those cold-stored with added N-acetylcysteine at varying concentrations. After five days of storage, we measured ROS production, lipid peroxidation, platelet activation, and other quality indicators.

Our findings highlighted that N-acetylcysteine effectively diminished the production of ROS, thus protecting the cold-stored platelets from damage and premature clearance by the immune system in both lab settings and live models. Importantly, using the right amount of N-acetylcysteine significantly improved the survival of these platelets in circulation.

Overall, this study sheds light on the potential benefits of incorporating antioxidants in platelet storage practices to enhance their functionality and longevity.

Prevents bronchitis

I was sceptical about this Life Extension N-Acetyl-L-Cysteine (NAC) given other brands I'd had. However, it worked as hoped during my cold, preventing bronchitis. As someone with early emphysema and COPD, I use it at the first sign of a cold to avoid doctor visits. This will be my go-to NAC, as it’s effective and reasonably priced.

Great for shortening a cold! I bought it in anticipation of the cold and flu season, needing it sooner than expected after catching my husband's cold. I started feeling sick on the 31st and took a 600mg capsule twice daily. By the 5th, I was back at work, feeling much better! This time, I expelled nasty mucus easily and avoided a prolonged upper respiratory infection. I consider this a record recovery time for me!

This is an excellent cold remedy. It’s an absolute analogue of ACC, with 60 capsules for the same price as 10 effervescent tablets! Acetylcysteine acts as a mucolytic, expectorant, and antioxidant agent for respiratory diseases. When I begin to feel aches, I take an ACC capsule at night. Stay healthy!

Best cold remedy
I always have this NAC in my medicine cabinet; for colds, I take it with a complete set of vitamins, and for mastopathy (oestrogen dominance), I also use it with other treatments. In my opinion, this is the best.

Prevents illness
I recommend it. Since starting these supplements, I haven’t fallen ill, which used to happen frequently. When my husband caught a cold, he felt better almost immediately after taking them for just two days.

Alleviates cold
I purchased this for an estrogen regulation protocol. Interestingly, I developed a cold while using it, but it significantly helped in clearing mucus. I highly recommend it.
