Boost your overall health and athletic performance with the top rated fish oil supplements.
Fish oil supplements are vital aids for your overall health, whether you are a bodybuilder, powerlifter, or just the every day person who wants to prioritize heart health. While buying other supplements, many people immediately go for muscle building products such as protein powders and creatine and even other options multivitamins and amino acids. However, recent studies recommend you cannot skip out on heart health products like fish oils.
While they are often found in many of the foods we already eat, such as fish, taking fish oil supplements as a dietary supplement can boost our overall health to keep us in the gym and off the couch. No matter the time of year, your body needs the absolute best to continue to thrive and see those gains we all know and love.
Typically you see fish oil supplements in two different versions, krill oil and fish oil. Although they are fatty acids, this is one kind of fat to keep around, and for good reason. Fish oil is one popular supplement many people take for a variety of reasons, including fighting anxiety and depression, improving eye and heart health, promoting bone and joint health, reducing inflammation, as well as keeping you in overall top shape to see your gains come to fruition and keep your athletic performance in top shape. Krill oil is another omega-3 supplement to consider that could potentially dethrone the popular fish oil by providing the same benefits. It has been observed that krill oil can enhance bioavailability allowing for better digestion than fish oil (1).
Our team at Generation Iron has put together a list of the Best Fish Oil Supplements for 2025 so you can be well on your way to boosting your own health and wellness while working to maximize your gains.

What Are Omega-3 Fatty Acids?
There are three kinds of omega-3 fatty acids to know about when diving into the world of these supplements. The two most important ones are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), both of which are found in certain kinds of fish. The third is alpha-linolenic acid (ALA), which is found in different plant sources like nuts and seeds. We won’t worry as much about ALA, but know there is a plant-based option for those looking. With both krill oil and fish oil high in EPA and DHA, with booming benefits for your overall health, the choice of which one is better becomes a little more challenging as the differences tend to be more subtle than not (2).
What Are The Benefits Of Omega-3 Supplements?
Omega-3 fatty acids are important and can really work for your benefit when it comes to overall health and wellness. Of course, the healthier you are, the better able you are at tackling any workout that comes your way, who doesn’t want that?
Benefits of omega-3 supplements include:
- Promote eye health: Work to improve the structural component of your retinas to prevent degeneration.
- Fight inflammation: Can reduce substances that are linked to and cause inflammation (4).
- Enhance heart health: Lower blood pressure and slow plaque development in the arteries (5).
- Increase bone and joint health: Boost calcium in your bones and can reduce joint pain.
What’s In These Omega-3 Supplements?
The main three ingredients that make up a well-rounded omega-3 are:
- Eicosapentaenoic acid (EPA): Found in cold water fish like herring, mackerel, halibut, among others. Some of the many benefits of EPA include lowering symptoms of depression, reducing your risk of heart disease, easing symptoms of menopause, and slowing the progression of arthritis (6).
- Docosahexaenoic acid (DHA): Found in fish and other cold water multi-cellular organisms. Benefits of DHA include reducing your risk of heart disease, fighting inflammation and supporting muscle recovery, and working to promote better eye health.
- Astaxanthin: A natural, red pigmented ketocarotenoid with powerful antioxidant properties. Benefits include reducing exercise fatigue, aiding in heart health, boosting cognitive function, and working as an anti-inflammatory (7).
What Else To Know
When looking to take an omega-3 supplement, somewhere around 3,000-5,000mg is safe, but most people don’t need that high of a dose. Always reading the label is helpful when starting to take these supplements for these honest and transparent companies on our list will disclose important information on the bottle.
