    Firstly, its taste is terrible when dissolved in water! It seems to be very effective though. I take it mainly to ease my at times severe OCD symptoms, and it works surprisingly well. For this it is recommended.

    Instant Results ! Taken before a meal it really seems to set the stomach up for digestion, then it really kicks in with higher energy and mental clarity. I was mega stressed and fatigued when I started on NAC ~ I really did get that " 10 years Younger " feeling.
    Always good and fast service from BulkNutrients

    N Acetyl Cysteine (NAC)

    Reduced soreness after training and stronger and more energy when training. Only trying this - looks like it will be a regular in my supplement regime from now on~

    I've been using NAC for year in various forms. Main use (larger doses) is as a mucolytic to get rid of phlegm when I have the occasional cold. I also take a "maintenance dose" daily with multivitamins as an antioxidant and for its (albeit unproven) anti-mutogenic benefit to ex-smokers. Some swear by its hangover prevention virtues. I can carry on, but let's stop with : It tastes so bad it's got to be good for you!

    Best in class

    Tried other NAC brands, capsules and powders. It has helped me through 3 years worth of lung radiation. Nothing beats Bulk Nutrient's product. Fastest shipping too. 1 day from Tas to GC Qld.

    Exceeded my expectations

    I bought this to decongest my lungs but when I continued reading about it I realised it has so many more advantages! It helps clear my lungs but is amazing for alleviating anxiety and improving focus. I will never be without it again!

    Good quality but extremely sour

    The quality of this product is great, but the extremely sour taste has discouraged me from using it
