Omega-3 fatty acids, also known as polyunsaturated fatty acids (PUFAs), are essential fatty acids that are implicated in several bodily functions. The body cannot produce these fatty acids on its own, making it necessary to get the required amounts from food (e.g. fatty fish) or via supplementation. Omega-3 fatty acids can be found in fish, such as salmon, cod, tuna, and halibut. They can also be found in other marine food sources, such as krill and algae, as well as in some terrestrial plants and nut oils.

Perhaps best known for their crucial role in supporting cardiovascular and joint health, omega-3 fatty acids are also extremely important for brain function and normal growth and development.

Most fish oil supplements are either available in ethyl ester form or triglyceride form. Structurally, the major difference between the two forms is that in ethyl ester, the fatty acids (EPA & DHA) are esterified to an ethanol backbone, while in triglyceride, the fatty acids are esterified to a glycerol alcohol backbone. Our Double Strength and Triple Strength omega-3 fish oils are in triglyceride form, which is the preferred form for optimal bioavailability.
