Effective omega-3 dietary supplements: proved by science

Section 1: What is omega-3 fatty acids?

Omega-3 fatty acids is a family of polyunsaturated fatty acids (PNS) necessary for human health, but not synthesized by the body in sufficient quantities. Therefore, they should come from food or additives. Key omega-3 fatty acids include:

Alpha-linolenic acid (Alk, ALA): Vegetable omega-3, contained in linen seeds, walnuts, chia seeds and some vegetable oils. The body can convert ALK in EPA and DHA, but the effectiveness of this process is limited, especially in men.
Eicopentenic acid (EPK, EPA): The main source is oily fish and fish oil supplements. EPA plays an important role in reducing inflammation, maintaining heart health and improving mood.
Dokosagexic acid (DGK, DHA): It is also contained in oily fish and fish oil supplements. DHA is critical of the development and functioning of the brain, vision and the nervous system.

Section 2: Omega-3 sources
