N Acetyl Cysteine (NAC) Reviews


Posted by Felix Scerri on November 14, 2019

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

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

Posted by Jennifer P on September 1, 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 June 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

Great value for money
