Effective cold remedy
Excellent cold remedy! It's an absolute analogue of ACC, and while we have just 10 effervescent tablets, this product provides 60 capsules—a significant difference. Acetylcysteine serves as a mucolytic, expectorant, and antioxidant, effective for respiratory diseases involving viscous sputum. When I feel aches or start to get unwell, I take an ACC capsule at night. Be healthy!

Prevents chest infections
Before taking this daily, I often developed chest infections after a simple cold. Now, I either don’t get them or if I do, they’re mild. N-acetyl cysteine has been a long-term treatment for similar issues in respiratory patients, and I suspect it aids me when I have a cold. I take 3000mg daily.

Relieves cold symptoms
I trust Life Extension completely; I've purchased their products several times and have always found top quality. Their NAC supplements are detox regulators that enhance glutathione production, improving resistance. I take one capsule each morning before breakfast. It significantly alleviates my cold symptoms while being well-tolerated.

Excellent cold remedy
Precursor of glutathione - the primary antioxidant in the body. Anyone at risk of the common cold should take 1 drop continuously, at the first signs of any cold or ARVI - 600mg three times daily, with 900mg during covid. I’ve been using it for a long time with my family for any cold manifestations - excellent results! Within 2-3 days, everyone is well again. I cannot imagine how we managed before. We take it alongside Vitamin D, Vitamin C, and zinc. Highly recommend!

Prevents bronchitis
I was initially skeptical about this brand due to its price but had no complaints. I have early-stage emphysema and COPD; when I catch a cold, it usually escalates into bronchitis, driving me to the doctor. I use this at the first sign of a cold and often manage to avoid bronchitis and medical visits. Following one cold since I purchased this, it performed as expected. This will be my preferred brand for N-Acetyl-L-Cysteine (NAC) as the price is reasonable, and it works. Highly recommended!

Relieves phlegm
Excellent quality N-Acetyl L-Cysteine. I consume it in different amounts, including as a hot drink for a cold. The flavour is pleasant, and it effectively detoxifies, eases phlegm, alleviates headaches, and helps with perspiration. I plan to continue using it.

Speeds up recovery
A reliable remedy for colds, I use it for protection against colds rather than daily consumption. I took one capsule twice a day at the onset of symptoms; the cold either vanished or passed quickly. The capsules are easy to swallow, and while it may cause some bloating for those with sulfur intolerance, I experienced no negative effects. It's a high-quality product that I recommend.

Supports respiratory health
I keep NAC at home as a first aid measure. It's beneficial for supporting the nervous system and acts as a mucolytic, expectorant, and antioxidant. It’s particularly useful for colds and flu. I aim to drink plenty of water while using it, as recommended.
