Omega-3 fatty acids are polyunsaturated fatty acids that everyone needs as part of essential dietary requirements. There are two other Omega fatty acids - Omega-6 and Omega-9, however we can easily obtain this from food sources or through production in our bodies, with most people lacking enough Omega-3s in their diet.
There are 3 types of omega-3 fatty acids: Eicosapentaenoic acid (EPA), Docosahexaenoic acid (DHA), and Alpha-linolenic acid (ALA). EPA and DHA are usually found in fish and other sources, like salmon, sardines and cod liver oil. ALA can be found in plant oils like flaxseed, soybean and canola oils. While ALA can be converted into EPA and DHA the rate of conversion is low, and the effectiveness of EPA and DHA acids tend to be higher than ALA.
Since most of these omega-3 essential fatty acids cannot be produced by the body, thus the way to obtain them is to consume more foods or food supplement for nutritional support. It is recommended for adults to consume about 250mg to 500mg of EPA and DHA per day, which is the equivalent of 2 to 3 servings of oily fish per week or via supplementation with daily Omega-3 supplements.You can find Omega-3s in these food sources:
- Oily fish, eg. salmon, tuna, mackerel, herring and sardines
- Nuts and seeds, eg. flaxseeds, chia seeds and walnuts
- Seaweed and algae
- Plant oils, eg. soybean oil and flaxseed oil
Benefits of Omega-3 supplements
Omega-3 fatty acids are needed as an essential part of supporting the heart, brain and vision. Some of the benefits include:
Heart health: Omega-3s help to maintain healthy cholesterol and triglyceride levels, reduce the risk of cardiovascular problems and regulate blood pressure.
Anti-Inflammatory: It is thought that Omega-3s reduce inflammatory reactions, thus leading to lower cardiovascular disease, reducing the rate of arthritis, auto-immune conditions and even joint and muscle pain. They can also help to repair cells and reduce swelling, thus improving skin conditions like eczema and psoriasis.
Memory and Cognitive Health: Omega-3s are essential building blocks of the brain, which is made up of 60% fat. Due to its anti-inflammatory properties, Omega-3s can help improve cognitive function and memory.
Fetal Development: DHA, one of the Omega-3 fatty acids, plays an important function during pregnancy to boost development for the fetus, especially for the healthy growth of the baby’s brain, eyesight and nervous system.
Eye Health: DHA also plays an important structural role in your retina, which is required for visual recognition and may contribute to maintaining your vision. Lower levels of DHA may also affect age-related macular degeneration (AMD), creating even more of a need to consume sufficient Omega-3s.
Side effects of taking Omega-3 supplements
Omega-3 supplements are generally safe to be taken according to the recommended dosages instructed on the bottles. According to the European Food Safety Association, the maximum dosage should not be more than 5000mg per day. Omega-3s may also cause some discomfort like acid reflux, with belching, nausea and stomach upset due to the high fat content of fish oils. Consuming more than the required amounts of Omega-3s may also increase the risk of bleeding. Do consult your healthcare professional if you have any questions regarding taking any supplements.
