What are Omega-3s?
Omega-3s are polyunsaturated fatty acids that play an important role in the body and provide numerous health benefits. These fats are considered as essential because the body requires them for important functions, but the body cannot produce them in the amount it needs to survive. That is why you need to get them from the foods you eat, and where required, from supplements.
Types of omega-3s
There are mainly three types of omega-3 fatty acids. Here are common food sources of these three:
- ALA (alpha-linolenic acid): Plant foods, like flaxseeds, canola oil, walnuts, chia seeds, soybean oil, etc.
- DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid): Fatty fish like salmon, sardines, mackerel, herring, tuna, etc.
Omega-3 benefits
Known as ‘healthy fats’, omega-3 fatty acids support various systems and functions in the body. Some of the common benefits of omega-3s, as per studies, include:
- May support heart health: Omega-3s are considered important for good health, especially for the heart and blood vessels. EPA may reduce blood triglycerides and support heart rhythm. DHA is important for heart function. Omega-3s may also help reduce the risk of developing an irregular heartbeat.
- May support brain health: Several studies suggest that omega-3s may help support the strength and structure of brain cells. DHA may help reduce the formation of plaques in the brain, which can affect memory function.
- May support joint health: Omega-3 fatty acids are important for maintaining the health of tissue structures, including joint structures. These fats may help with joint stiffness and limited mobility.
- May support eye health: DHA is concentrated in the retina, and may contribute to the structure and function of photoreceptor health. Adequate omega-3 intake, thus, may help support healthy eye function and visual health.
- May support skin health: DHA is a structural component of the skin, which is the largest organ of the body. And, EPA may help support skin hydration and reduce the risk of acne. Omega-3s may contribute to the lipid content of the skin’s outer layer, and thus, may help maintain the barrier function of the skin.

Why is fish oil important for omega-3 intake?
Fish oil is popular among Australians as a source of omega-3 fatty acids. Of the three main types of omega-3s, DHA and EPA are found in fish and so are also called marine omega-3s. ALA, which is found in plants, can be converted by the body to EPA and DHA. But this process provides only a small amount of EPA and DHA, which makes it important to get these fatty acids from food sources. Since both these fatty acids are derived from fish, including fish in your food or fish oil supplements in your diet becomes important.
Which are the best fish oil supplements in Australia?
Studies suggest that only 10% of Australian adults successfully meet the RDI (Recommended Daily Intake) of omega-3s through diet. That’s when a GP-suggested supplement can be helpful. There are various fish oil capsules and omega-3 supplements available in Australia. Some of the popular supplements from trusted brands include:
- Thompson’s Omega 3 Odourless Fish Oil: Fish oil capsules that may work as a source of omega-3 fatty acids, which is required by the body. It may help support general well-being.
- Blackmores Fish Oil 1000 Capsules: Omega-3 supplement containing natural fish oil, which may help heart, skin, eye, and brain health.
- Henry Blooms Natural Fish Oil 1000: Capsules rich in omega-3, which may help support joint, heart, and brain health.
It is always advisable to consult a healthcare professional before starting to use any supplement for tailored advice and safe use.
