How do we compare ?
  • One of the strongest Nac supplements you can buy online

Nasty-Free, is there brown rice flour in your NAC ? This is used as a bulking agent so supplement companies can make that 200kg go to 400kg so they can make more money by creating more products.

What happens to the quality of the supplement ? Well its not what its supposed to be right ? Have a look at the ingredients list yourself for the usual suspects like Maltodextrin (Corn), brown rice flour that are used to do this.  

  • Other Nasties include Magnesium Stearate, Silicone Dioxide etc. They use these to help the machines work so they can mass produce the pills and get the price down as low as possible. Quality goes out the window when you see any of these nasties in your supplement. You can Google the potential side effects you can get from taking these.

Plus our products are CLEAN they all add Nastys because they are made for money and not for human consumption.

This is my first order from British supplements, I haven’t been taking them for long enough to know if their beneficial, however I like they have no added fillers or binders

Early days but decent progress

Blood work shows improvement in key areas already. Will report again in a month. Thanks Chris and team. This is not just about Nac but various Supps

Post covid syndrome

Within days of starting to take NAC my post covid syndrome symptoms started to improve. My gut pains have now completely gone. As has the headache. My heart is improving. The dreadful covid fatigue is greatly improved and I feel like myself again. NAC has been like a miracle for me.

I am amazed.

Dear Chris, I just wanted to let you know how NAC has helped both me and my husband.
My husband has fibromyalgia, so he feels like he has the flu every day of his life, so you can imagine how poorly he was when he contracted Covid 19 in June! I have never seen him so poorly. We couldn't get rid of the congestion in his head, sinuses or chest. He had a terrible cough and the exhaustion lasted for weeks.
I couldn't believe it when he tested positive again for covid on Monday!!! I take NAC for an autoimmune disorder I have. It helps to boost my immunity as it is anti inflammatory. I have noticed the pains in my back and joints have gone away.(maybe the vit D, K, vitC and Zinc help too) I remembered when I was researching about the benefits of NAC how covid DRS and nurses would take NAC as a precautionary measure as they couldn't afford to get ill. So I immediately gave him some. He has been taking it twice a day along with vit D,K, C and Zinc. It seems like the virus has not been able to get a hold on him. He has no congestion, no continuous cough. Don't get me wrong, he has felt ill, but not a patch on what he was last time. I know he has some immunity from having it in June, but today after only 5 days he had his first negative test!!!! This stuff is amazing. I have not (as yet) developed any symptoms and and we live in a very small house. I am sure this is helping protect me too.

Also as a pleasant sidenote, I have noticed that my grey hairs are not so noticeable, they haven't exactly gone but definitely not as pronounced!!!
Thank you so much for such good products.
