Every Batch 3rd Party Tested
The supplement industry's dirty secret is that most brands never test what they sell. We do the opposite. Every batch we manufacture is sent to an independent, ISO 17025:2017 accredited third-party laboratory before it ever reaches your door — we work with Eurofins, SORA Labs and Alkemist Labs. Every Certificate of Analysis is published online — scannable, searchable, and free to view.
Raw ingredients tested on arrival
Every raw ingredient is tested for heavy metals, microbials, and potency before it enters our Oxford facility. If it fails, it never goes into production.
Manufactured in-house under GMP
We don't outsource to contract manufacturers. Every capsule is made in our own GMP-certified UK facility in Kidlington, Oxford — fully traceable, batch by batch.
Finished batch tested independently
A sample from every finished batch goes to an accredited third-party lab — Eurofins, SORA Labs or Alkemist Labs — for verification. Potency, purity, heavy metals, microbial contamination — all tested by a lab with zero ties to us.
Certificate published before shipping
Every Certificate of Analysis is uploaded to our public testing database. Scan the batch code on your bottle and read the exact lab report for the capsules in your hand.
Targeted formulas, clinically dosed.
Every product is built from peer-reviewed dose research — not marketing. Find what you need.

We tested 7 of the UK's top Nattokinase brands. All 7 were ripping people off.
We bought the best-selling Nattokinase pills on Amazon and sent them to SORA Labs (ISO 17025:2017) — one of the same independent, accredited laboratories we use for our own batches. Same enzyme assay. Same lab. Same day.

All testing performed by SORA Labs (ISO 17025:2017). 7 out of 7 competitor brands delivered less than what they promised on the label. One brand had just 17.8% of label claim — meaning if you paid £30, you got £5 worth of actual product. The rest? Filler.

In 3 weeks my BP went from 160/97 to 124/75. Unbelievable results — tried NFS after struggling to get my blood pressure in range.
My BP dropped 10mmHg when I started using the product and has remained stable since then. Been using the Blood Pressure Support for several months now.
If you're struggling with high blood pressure despite being on medication — this stuff is for you! My GP was extremely concerned as mine was sky high on the highest dose.
Absolutely amazing product. I tried everything to lower my blood pressure which at its worst was 182/101. Only 3 weeks later it's now regularly 128.
Been using the Blood Pressure Support for 3 weeks and there's a very noticeable drop. Easy to add to daily routine and doesn't taste bad at all.
Absolutely brilliant! Got for my husband who had high blood pressure and didn't want to use prescribed medication. This is a game changer — blood pressure now in the green!
I had high blood pressure at 138/92 and after 1 month of this with 2 drinks a day it is now down to 128/85. Now on my 3rd order with NFS.

I tested the big brands on YouTube. What I found started this company.
It started on my YouTube channel. I bought the best-selling supplement brands off Amazon and sent them to accredited third-party labs — then published exactly what was really inside them.
What came back made me angry. Brand after brand was massively underdosed. Some had almost no active ingredient at all. People were paying real money for products that didn't come close to the claims on the label.
So I did something about it. I started NF Supplements — a brand built on the two things most of the industry ignores: independent third-party testing and genuine quality. We make every batch ourselves, test every batch with an accredited lab, and publish every result online. No tricks. No hiding.
These are the supplements I take every day myself. There's nothing hidden in here, and there never will be. You have my word.
