    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

    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

    Posted by Jennifer P on Sep 01, 2018

    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

    Posted by Anon on Jun 16, 2018

    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

    Posted by Peter on May 30, 2018

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