How do we compare ?
  • One of the Strongest Quercetin supplements you can buy if not the strongest.
  • Nasty-Free There is ZERO bulkers in our Quercetin, check the back of your last Quercetin supplement. Does it say maltodextrin or microcrystalline cellulose maybe ? These are bulkers to make their product go further so they can make more money. Same as the drug dealers do so that is one reason your supplement isn't really going to do much for you.
  • Or maybe there is a flow agent like Magnesium stearate or Silicon Dioxide ? All of these have Nasty side effects, you can google them yourself and read up on them.
  • One of the main reasons you probably dont know about fillers, binders and flowing agents etc is because pretty much every pill the doctor prescribes you have them in it, minimum 50% of the pills most of the time and up 99% depending on the drug.
  • The system only want you to have one choice and call anything else Quackery which is hilarious when you can see them for who they are.
  • They dont want you to question anything just follow along like a good cash cow until they milk you dry.

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

Quercetin - Helps Histamine Intolerance

I’ve been taking Quercetin fir several months now, one in the morning & one in the evening.

I was suffering from what I though was severe allergies (sneezing, itchy eyes, itchy roof of mouth, runny nose & dry eyes - as I was taking antihistamines they were making this worse)

I’m now off the antihistamine & feeling so much better!

Aileen Hamil

British Supplements have been my go to for several months now. I have started taking quercetin in addition to several others and read reviews about how this has helped allergy sufferers with pets. We have a new pup and my asthma flared up, having me take my inhaler and antihistamines. On the 1st day taking the supplements I noticed a difference, on the second I’ve not needed anything!! I’m honestly blown away by this. It’s amazing stuff!!

Protecting the Immune System

Quercetin is one of the Supplements that boosts the Immune System, among others, like Echinacea, Olive Leaf, Zinc & vitamin C amongst others, everyone needs to check their supplements this time of year.

Correctly dosed, clean supps that work

I have purchased many supplements over the years from a many vendors. I've read all the claims they make, and bought into their promises, often to only be disappointed. But British supplements have really lived up to my expectations. I purchased Clean Quercetin 651mg + Uptake Blend couple of weeks ago and they have helped my prostatitis significantly. I am very grateful for this and would recommend British Supplements with confidence.

Clean Quercetin stops my seasonal allergies

I have had terrible issues with seasonal allergies in the last 4 years and they were worsening. Itchy, streaming eyes, constant sneezing fits and feeling like I had a full blown cold every evening.
I’ve tried lots of remedies none of which have worked apart from high dose VitC which is hard to maintain and Clean Quercetin from BS along with their recommendations of Clean Nettle leaf, NAC and Vit D, C and K2.
I’m clear of allergies now while my family members (grown up children) are all sneezing and suffering.
If I forget to take them for a day or two - my allergies return. So now I never forget. I’ve told my children so hopefully they will be buying the same supplements from BS.
