Omega 3

Ingredients

Omega-3 fatty acids are essential and long-chain polyunsaturated fats found in foods and dietary supplements. The three main omega-3s are ALA (alpha-linolenic acid), EPA (eicosapentaenoic acid), and DHA (docosahexaenoic acid). ALA is found mainly in plant foods and oils, while EPA and DHA are found primarily in fatty fish, seafood, fish oil, krill oil, and algal oil.

Omega-3 fatty acids are important dietary fats that play structural and functional roles throughout the body. The main types are ALA, EPA, and DHA. ALA is an essential fatty acid that must be obtained from the diet, while the body can convert only small amounts of ALA into EPA and DHA.

Plant sources such as flaxseed, chia seeds, walnuts, soybean oil, and canola oil provide ALA. Fatty fish such as salmon, sardines, mackerel, and herring provide EPA and DHA. Dietary supplements may contain fish oil, krill oil, cod liver oil, or algal oil, with formulations varying considerably in the amount and form of EPA and DHA.

Omega-3 supplements are commonly used in general nutritional, cardiovascular, brain, eye, pregnancy, and active-lifestyle nutrition formulas. DHA is particularly concentrated in tissues such as the brain and retina, while EPA and DHA are important components of cell membranes and participate in several biological processes.

Because omega-3 products differ substantially in their source, EPA/DHA content, chemical form, serving size, and additional ingredients, consumers should check the product label carefully. High-dose omega-3 supplements can also interact with medicines such as anticoagulants, so people taking regular medication should discuss supplementation with a healthcare professional.
