How to choose the best omega-3 supplement and what to watch for.

Omega-3 fatty acids are some of the most researched and essential nutrients for human health. Their role in supporting the cardiovascular system, nourishing the brain, maintaining vision, and regulating inflammation is not only well-documented but crucial to our daily well-being. And yet, despite this widespread knowledge, global intake remains alarmingly low. A 2017 study revealed that 98% of people worldwide don’t consume enough omega-3s to support optimal protection against conditions like cardiovascular disease.

​This deficit highlights a clear need for effective supplementation. With so many options on the market, how do you know which omega-3 supplement is truly worth your investment? The truth is, not all fish oil or plant-based omega-3 products are created equal. To make an informed choice, you need to look deeper than marketing labels and high capsule counts. Instead, the quality of what is inside, specifically the content of EPA and DHA, defines the purity and potency of your supplement.

​Let us explore how to assess omega-3 supplements properly, and how the Physalis omega-3 range, from forte and vegan to total and ultra, has been thoughtfully developed to meet different needs without compromising on purity, transparency, or efficacy.

​EPA and DHA: The True Measure of an Omega-3 Supplement

While many fish oil supplements advertise high milligram counts of fish or algal oil, what really matters is how much of that oil contains the active compounds EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These are the biologically essential fatty acids your body uses to fuel key physiological functions. From maintaining heart rhythm to supporting cognitive clarity and mental balance, EPA and DHA are key.

Unlike short-chain omega-3s like ALA (alpha-linolenic acid), which must be converted in the body to EPA and DHA (often inefficiently), these two long-chain forms are already in the form your body needs. That’s why leading health authorities recommend focusing specifically on EPA and DHA intake.

A healthy adult should aim for 1000 mg of fish oil - 600 mg of combined EPA and DHA per day. People with specific needs, such as athletes, pregnant women, or individuals managing cardiovascular or inflammatory conditions, may benefit from higher intakes, sometimes exceeding 1000 mg daily.

​Concentration Counts: Understanding Omega-3 Percentages

One of the most important aspects of supplement quality is omega-3 concentration. More specifically, how much EPA and DHA you actually get relative to the total oil content. Just because a capsule contains 1000 mg of fish oil does not mean you are getting an effective dose of active ingredients.

Here is where label literacy matters. A high-quality fish oil supplement will disclose either the percentage of EPA and DHA or their exact quantities in milligrams. For example, a supplement that delivers 600 mg of EPA and DHA per 1000 mg of oil has a 60% omega-3 concentration. In contrast, lower-tier products may only provide 30%. This means you would need to take twice as much to achieve the same benefit.

If you do not see EPA and DHA amounts clearly listed, it is a red flag. Reputable brands want you to know what you are putting in your body. Transparency is not just a marker of honesty, it is a marker of quality and responsibility.

Sourcing: Purity, Sustainability, and Transparency

​When choosing a quality fish oil supplement, the source of the ingredients is highly important. Look for products made with oils that have well-documented fatty acid profiles rigorously tested to ensure purity. Supplements should be free from contaminants like heavy metals, PCBs, and dioxins. Reputable suppliers follow internationally recognised sustainability standards such as Friend of the Sea (FOS) and the Marine Stewardship Council (MSC), which protect marine ecosystems while maintaining resource integrity. For plant-based options, seek out algae oils sourced from responsibly managed cultivation systems. These standards ensure that supplements support not only your health, but the health of marine ecosystems as well.

Omega 3 forte

Omega 3 forte is the go-to option for individuals looking for a highly concentrated, potent dose of omega-3s. Sourced from sustainable fish oil and carefully balanced to reflect the natural 1.5:1 EPA to DHA ratio, this product supports cardiovascular function, brain performance, and eye health. Its strength makes it a reliable choice for daily health maintenance and for those with moderate to high omega-3 requirements. Per 3 capsules you get 1500mg fish oil - 540mg of DHA and 360mg EPA.

Omega 3 vegan

On the other hand, Omega 3 vegan is designed for individuals who avoid animal products or have sensitivities to (shell)fish. It contains algae-derived EPA and DHA in a naturally rich triglyceride form. This provides a high DHA ratio that is especially supportive of brain development, memory, and vision. It is an excellent choice for vegans, vegetarians, or anyone looking for a plant-based source of long-chain omega-3s, providing 750mg of algae oil per capsule, of which 375mg DHA and 150mg EPA.

Omega 3 ultra

Omega 3 ultra is a maximum strength formula that delivers ultra-concentrated levels of EPA and DHA. With 1400mg of fish oil (672mg EPA and 44mg DHA), this is our highest concentration supplement. This type of product is often preferred by those with very high omega-3 needs. This includes athletes, individuals with inflammatory conditions, or anyone seeking a clinically therapeutic dose in a convenient format. One important thing to note is that the EPA and DHA used is in the form of r-triglyceride. This from more closely resembles the natural structure of fish oil. It is thus more easily absorbed and contains a higher concentration of omega-3 fatty acids without excess saturated fats.

​Omega total

For those who want broad-spectrum fatty acid support, Omega total goes beyond just omega-3s. It combines omega 3, 5, 6, 7, and 9 fatty acids from both marine and plant-based sources, offering comprehensive support for skin, inflammation, cardiovascular health, and cellular balance. This holistic blend may appeal to those dealing with multiple health concerns or looking to support their body on several fronts, including hormonal balance, skin regeneration, and metabolic health. Per 2 capsules you will get 608mg of fish oil.

​As with any supplement however, the best results come from matching the right product to the right person. Your age, diet, lifestyle, health goals, and even genetics can influence your omega-3 needs and from which source. If your diet is rich in seafood, organic free-range eggs, walnuts, flax- and chiaseeds, you are already getting a good dose. In this case, supplement needs can be looked at depending on symptoms. Speak to your healthcare provider for more clarity about which supplement is most suited to your needs at this time.

For Athletes and High-Demand Lifestyles

Omega-3s are especially vital for athletes and physically active individuals. The combination of oxidative stress and micro-inflammation from intense training increases the body’s demand for anti-inflammatory and neuroprotective support.

EPA helps mitigate inflammation, aiding faster recovery and joint support, while DHA promotes mental clarity, reaction speed, and eye health. A high-EPA/DHA supplement, like Omega 3 forte or ultra, is particularly well suited for this group as athletes may require up to 1000 mg or more of combined EPA and DHA daily.

​The Bottom Line on Omega-3s

​In the world of nutritional supplements, omega-3s are among the most essential. Yet sadly, also one of the most misunderstood. It is about more than just how many milligrams of fish or algal oil you consume. What matters is the EPA and DHA content, the purity of the source, and the transparency of the label.

At Physalis, we care deeply about each one of these. Our range of omega-3 products delivers potent, responsibly sourced, and clearly labelled supplements tailored to different needs and lifestyles. Whether you are a seasoned athlete, a health-conscious parent, or someone looking to age well, there is an omega-3 for you.

And with so many benefits packed into every capsule, such as better heart function, sharper thinking, healthier eyes, and balanced immune response, the question is not whether you should be taking omega-3s. The real question is: Are you taking the right one?
