mixes well and tastes nice
Easily dissolves in water and has a pleasant citrussy taste. Aids recovery and helps keep me fresh, and a very reasonable price as it lasts ages.

Brilliant Quality/Tasting NAC powder
I have tried many different brands of NAC powder over the years and this one is the best version in my opinion. The main reason for me using it is to cleanse both my Liver and Kidneys from painkillers and also naughty things Ahem .... You know what I mean as this is why everyone uses this stuff! Another benefit I also found out about NAC is if you have a headache and you take some Paracetamol for example, it makes the paracetamol more effective at getting rid of the pain you are feeling so effectively you can take less of it. I know it sounds surprising as it was originally used for Paracetamol overdose in Hospitals but it is a true fact if you look it up. I have a strong liking for sweet and sour sweets and this tastes strongly of those so I actually enjoy using the stuff.Goes Well With:Dextrose / Glucose Carbs PeptoPro Casein Shakes Whey Shakes
Report this reviewmixes well
Gives me pep, mixes well (doesn't taste amazing but isn't awful and isn't sweet) and is great value
Report this reviewTastes horrible, nauseous all day
The taste and smell is horrible and the product made me nauseous all day. I have used 100% NAC products in capsule form before without having this issue, so this is not caused by the working ingredient. Tried it in a protein shake, water, tea, lemonade, but none masked the taste and smell. DO NOT recommend.
