Fish have been consumed for many years and the health benefits have been known for a long time. Traditionally this was based on its excellent protein quality and available micronutrients. It is only in the last 30 years, that science and research have shown that the predominant health benefits of fish come from the natural fish oil. Fish oil is unique because it contains a high concentration of polyunsaturated fatty acids which are popularly known as omega-3.
The two main fatty acids of interest are known as EPA and DHA. These fatty acids are present in other foods but only in very small amounts. The omega-3 fatty acid Alpha Linolenic Acid (ALA) found in some vegetable oils does not have the same health benefits as EPA and DHA.
Official recommendations of how much of long chain omega-3 we should consume on a daily basis vary from 200 mg to 1 gram (g) per day. A well known and respected Professor of Nutrition, Philip Calder, has recently reported that we need at least 1 g per day to achieve any marked beneficial effects. The uptake of these fatty acids is measured by analysing one’s blood.

Fish or supplements?
In New Zealand and Australia, commonly eaten white fish like snapper and terakihi are nutritious, but naturally lower in oil—and therefore lower in omega-3—than oily fish like salmon. Oily fish such as king salmon, when consumed regularly, can contribute meaningful levels of omega-3 to the diet.
However, it can be challenging for many people to include enough oily fish in their weekly routine to maintain consistent omega-3 levels. That’s why omega-3 supplements are a popular option for those looking to support their intake in a convenient way.

Clinical Evidence
Lester's Oil — New Zealand's Fish oil backed by a human study
Lester's Oil is a multi-oil omega-3 formula put to the test in a study conducted by Auckland University, which found omega-3 levels increased by 59% in just 4 weeks.
It's the only study of its kind conducted on a New Zealand fish oil supplement.
