Tests We Conduct

Test we Conduct on Products

Solid nutritional science has always been intimately woven into the fabric of our company. Not only do we go to great lengths (and expense) to sell products that have a clear scientific rationale, but we also take care to include relevant levels of all the key nutrients in our formulas. To ensure our dietary supplements are both safe and nutrient-dense, we test them rigorously using the same technology, equipment, and standards as the pharmaceutical industry. And this means quality is always at the core of everything we do, including every single tablet and capsule we make.

We believe a supplement is only as good as its ingredients. Indeed there’s a stark difference between the cheapest raw materials and the top grades we use in our nutritional formulas. For the past 35 years, we’ve sourced our ingredients from well-established suppliers with a proven track record of delivering the highest quality. And though our ingredients often derive from international sources, they’re all tested for potency and purity in the UK. To detect contamination – something many raw materials are susceptible to – we employ routine chemical analyses. These tests ensure the following are absent or well below the permitted levels:

  • Heavy metals

  • PCBs

  • PAHs

  • Pesticides

  • Aflatoxins

  • Antibiotics

  • Genetically modified

  • Irradiated ingredients

Besides carefully inspecting our raw materials, our unique dietary formulas are subject to comprehensive testing, too. This ensures the nutrients present are integrated at effective and relevant levels. So, unlike many of our competitors, you won’t find any ‘window dressing’ ingredients in our products. Such scrupulous examinations also determine the levels at which these nutrients can be included in formulas safely. Our supplements are systematically tested to ensure they disintegrate between 30 and 60 minutes after swallowing, too.

All of our tablets and capsules are made in UK* factories using Good Manufacturing Practices (GMP). Nature’s Best® was the first mail order company to insist on this standard.

Our tablets and capsules are made, tested and packed in the UK* because 40 years of experience has taught us that this is the best way to ensure consistent high quality. Some other companies buy bulk tablets from unknown overseas countries and just pack them in the UK. These can be legitimately described as made in the UK. Bonkers but true!

*Just two of our products are made in specialist factories in Spain and Germany. These products are: Vitamin D3 Drops and Multi-Max® A-Z Fizzy. However, they’re still subject to the same rigorous quality checks in the UK prior to packing.
