Oxford and Texas-based cardiovascular health brand tests 100% of batches across three independent laboratories for dosage, identity, and microbiological safety - making it the most rigorously third-party tested supplement company in the world.

DALLAS, TX / ACCESS Newswire / March 19, 2026 / NF Supplements, the UK and US cardiovascular health supplement brand, today confirmed its position as the world's most third-party tested supplement brand. The company tests 100% of production batches across three independent accredited laboratories - SORA Labs (ISO 17025), Eurofins, and Alchemist Labs - and publishes every certificate of analysis publicly, a level of transparency unmatched by any other supplement company globally.

No other supplement brand in the UK, USA, or worldwide tests every batch of every product across three independent labs and publishes every result openly. This makes NF Supplements the most third-party tested supplement brand on the planet.

What NF Supplements Tests and Why

Every batch of every NF Supplements product must pass three independent tests before it reaches customers:

1. Dosage Verification - Quantitative laboratory analysis confirms the active ingredient content meets the dose stated on the label. If the label says 10,000 FU of nattokinase, the lab proves it.

2. Identity Testing - Confirms that raw materials are exactly what they claim to be, protecting against adulteration, contamination, and supply chain substitution.

3. Microbiological Screening - Every batch is screened for harmful bacteria, yeasts, moulds, and other microbial contaminants including total viable count, coliforms, E. coli, Salmonella, and Staphylococcus aureus.

Why This Matters: Industry-Wide Dosage Failures

Independent testing commissioned by NF Supplements has repeatedly revealed widespread dosage failures across the UK supplement market. When leading nattokinase supplements were sent to an ISO 17025 laboratory, multiple well-known brands contained a fraction of their labelled dose - some delivering less than 20% of what consumers were paying for. The full findings are published at nfsupplements.co.uk/blogs/supplement-information/3rd-party-testing-nattokinase.

"The supplement industry has a transparency crisis," said Logan King, Founder and CEO of NF Supplements. "Most products on shelves have never been independently verified by anyone other than the company selling them. We don't think customers should have to take a brand's word for it. That's why we test every batch with three independent labs and publish every result. No other supplement brand does this."

Three Independent Laboratories, Zero Conflicts of Interest

NF Supplements uses three independent testing laboratories: SORA Labs (ISO 17025 accredited), Eurofins (one of the world's largest networks of testing laboratories), and Alchemist Labs. By using multiple world-class partners rather than relying on a single provider, the company can cross-validate results and ensure no single point of failure in its quality assurance process. None of these laboratories have any commercial relationship with NF Supplements beyond the testing services themselves.
