Renowned expert William Harris, Ph.D., a leading authority on omega-3, has conducted extensive studies that shed light on the importance of these essential fats for overall health and lifespan.

"People that had the highest omega-3 levels compared to the lowest were 15 percent or so less likely to die and it was very dose-dependent: the higher the omega-3, the lower the risk."

According to Dr. Harris's research, individuals with the highest omega-3 levels had a remarkable 15 percent lower likelihood of mortality compared to those with the lowest levels. This relationship showed a clear dose-dependent pattern, meaning that as omega-3 levels increased, the risk of mortality decreased further.

Supporting these findings, epidemiological studies involving over 42,000 participants across 17 prospective cohorts uncovered a strong link between omega-3 intake and reduced mortality risk. Those with the highest concentrations of long-chain omega-3s in their blood experienced a notable 15 to 18 percent decrease in all-cause mortality compared to those with the lowest levels. These results highlight the role of marine-derived omega-3 fatty acids in mitigating the risk of premature death.

These studies emphasize the potential of omega-3 fatty acids in extending lifespan and promoting overall well-being. While omega-3s are commonly found in fish and seafood, they can also be obtained through dietary supplements such as fish oil capsules. Incorporating omega-3-rich foods or supplements into our daily routines may offer a simple yet effective way to enhance our longevity and improve overall health.

Cautionary note: watch out for rancid fish oil products
Extensive independent testing conducted by 'Labdoor' has revealed that a significant number of fish oil supplements from major retail brands may be rancid. Out of the 60 popular brands tested, over 10 percent were identified as rancid, and nearly half were just below the recommended maximum limit for rancidity. Rancidity occurs when the product oxidizes, resulting in an unpleasant fishy taste and smell. It is important to note that consuming rancid fish oil can have negative health implications.

To mask the rancid odour, many companies add flavourings, making them more appealing but hiding the potential oxidation. Therefore, it is essential to be cautious when choosing fish oil supplements to ensure their quality and freshness.

In the clinic...
Increasingly, we are realising the value of testing patients' blood levels of omega-3 and omega-6 fatty acids, as well as other types of fatty acids. We notice that a low blood level or deficiency of omega-3 is associated with inflammation, autoimmunity, hormone issues, and even fatigue.

I think it is likely that in the near future, testing omega-3 levels will become a routine part of standard blood tests conducted by general practitioners.

The development of our Wild Alaskan Salmon oil was driven by its greater impact on patients' blood values when compared to other supplements.

Our Wild Alaskan Salmon oil is a full-spectrum product prepared quickly after harvesting to preserve the oil's integrity, eliminating the need for artificial flavourings or preservatives.
