Although we buy ingredients from all over the world, we only use well established UK agents who have an excellent track record in safety and quality assurance.

Good quality fish oils, such as ours, contain phospholipids that dramatically improve omega 3 absorption. They also contain an antioxidant called astaxanthin which helps keep the oil protected from oxidation. An investigation by showed that many popular fish oil brands were already oxidised before people even opened the bottle. As we have a good relationship with our long term loyal suppliers we know our oils are as fresh as possible and they have clear reliable use by dates. Furthermore, they are not exposed to the light and sealed immediately after packaging with airtight lids both limiting the risk of oxidation.

Bad quality fish oils could be contaminated heavy metals such as cadmium, mercury and arsenic as they use larger fish such as swordfish, king mackerel, tilefish, and albacore tuna. Fortunately, most fish oils have not been found to contain these heavy metals, especially ours which are made from smaller fish such as salmon, herring, mackerel, anchovies and sardines. Likewise some supplement have been found, by, to contain dioxins and polychlorinated biphenyls (PCBs) as they use fish from polluted seas or again larger fish which are higher up the food chain.

In another investigation from the it was found that some supplements claiming to be fish oils have a large percentage of other cheaper vegetable oils. So it is important to get your oils from a reputable source such as ours.

In summary natureMedical fish oils have:

  • A once a day dosage.
  • Are made by a trusted UK company.
  • Have reliable use by dates.
  • Have a low risk of heavy metal and toxin contamination.
  • Are endorse by a leading UK Oncologist.
