Fish oil is truly nature’s bounty, and its supplements promise many important health benefits, particularly being rich in omega-3 fatty acids, which can promote cardiovascular, visual, and skin health. 

But if you’re seeking a more plant-based alternative to fish oil, we’re rolling out our top picks for the best vegan alternative to fish oilalgae oil supplements, to help you narrow down on the right product.

Best Vegan Alternatives To Fish Oil – The List

While fish oil is an excellent source of omega-3 fatty acids, those who follow a vegan/vegetarian diet would naturally want to seek it from non-animal sources. Nuts, oil, and vegetables would then be part of their diet.

Algae oil is a great source of omega-3; others even consider it a greater and more sustainable source than fish oil since fish get their omega-3s from eating algae. Certain microalgae species are especially rich in two main types of omega-3 fatty acids EPA and DHA. As such, these species are grown for their oil.

Algae Oil Vs. Fish Oil

Studies show that algae oil has the same nutritional profile to fish oil, providing the same health benefits to your body. But aside from being a vegan/vegetarian option, how does algae oil fare better than fish oil?


As mentioned above, algae are considered the primary source of omega-3 fats, and all fish get their omega-3 content by eating it, making them only a secondary source, making the omega-3 oil sourced from algae more potent.


Algae oil is more bioavailable than most leading fish oil-based supplements in the market and is absorbed better by the body compared to fish oil or krill oil.  


Algal oil is a proven, sustainable alternative to fish oil since they are more environmentally friendly and ethical. Studies also consider algae oil a potentially sustainable form of renewable fuel.

Amount of Omega 3, EPA & DHA in the Fish Oil Alternatives

When it comes to any form of dietary supplementation, it’s not as simple as more = better. We need to take into account the Tolerable Upper Intake Level (UL) of the active ingredient we’re trying to supplement. So, what is the UL of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)?

The Panel on Dietetic Products, Nutrition and Allergies states that dietary recommendations for EPA and DHA based on cardiovascular risk considerations for European adults are between 250 and 500 mg/day. Supplemental intakes of DHA alone up to about 1g/day, do not raise safety concerns for the general population.

Algal Oil (mg)100050085020001650

When looked at through the lens of upper tolerable intake limits, we found the Calgee Vegan Omega 3 Supplement to offer the optimal dosages of EPA & DHA. Its combined EPA & DHA dosage of 450mg sits just below the UL of 500mg.

There is some research that suggests much higher dosages are needed to increase the Omega-3 concentration in your blood to the recommended range of 8 percent or greater. They put the daily intake number between 1,750 to 2,500 milligrams (1.75 to 2.5 grams) per day. If you want to follow this advice we’d recommend the BrainMD Omega 3 Supplement.

Benefits Of Omega-3 Fatty Acids

Fish oils come from fatty or oily fish, such as trout, mackerel, tuna, herring, sardines, and salmon. They contain omega-3 fatty acids (also called omega-3 fats and n-3 fats), particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA),  and many contain vitamins A and D.

Many people take fish oil and omega-3 supplements for their touted health benefits. Omega-3 fats stand out because they provide the starting point for making hormones that regulate blood clotting and bind to cell receptors that control genetic function. It also contains anti-inflammatory properties that prevent damage inside the artery walls and platelet aggregation. 

Since the body can’t produce omega-3 fatty acids on its own and must get them from food sources, omega-3 fatty acids are considered essential fats (not all fats are bad!). Aside from fish, foods rich in omega-3 include: 

  • Leafy vegetables (E.g., seaweed and algae, brussels sprouts, spinach, broccoli, etc.)
  • Nuts (Walnuts and brazil nuts)
  • Seeds (E.g., flax seeds, pumpkin, sunflower, chia, etc.)
  • Flaxseed oil
  • Vegetable oils
  • Grass-fed meats (beef, buffalo, and lamb)
  • Crab and shrimp.
  • Pasture-raised or omega-3 chicken.

The American College of Cardiology and the American Heart Association (ACC/AHA) recommends eating omega-3-rich fish (e.g., mackerel, tuna, sardines, etc.) as part of a heart-healthy diet, which serves to prevent heart disease, protect the brain and eye health,  contribute to fetal development, and improve skin health. 

Additional studies also prove that regularly eating a healthy balanced diet primarily composed of seafood may significantly improve heart health and lower the risk of coronary heart disease-related death and stroke. Both docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are essential nutrients in preventing and managing heart disease, promoting brain function, and reducing inflammation.

For healthy individuals with a low risk of heart disease, dietitians also recommend consuming oily fish at least twice a week (as part of a healthy balanced diet) to obtain adequate omega-3 fatty acids. 

Omega-3 fatty acids yield other important health benefits such as:

  • Lower blood pressure
  • Reduce triglyceride levels
  • Reduce fat in the liver
  • Prevents plaque development in the arteries
  • Lowers the risk of arrhythmia 
  • Lowers the risk of heart attacks, stroke, and death
  • Improve eyesight
  • Promote bone and joint health
  • Promote brain growth and development in infants
  • Improve sleep quality
  • Protect the skin against sun damage
  • Reduce acne 
  • Prevents dry, red, or itchy skin
  • Fight depression and anxiety


How do vegan alternatives to fish oil compare to traditional fish oil supplements in terms of their omega-3 content?

Vegan alternatives to fish oil, such as algal oil, can be just as high in omega-3 fatty acids as traditional fish oil supplements.

In fact, some studies suggest that algal oil may be even more effective than fish oil at raising levels of EPA and DHA, the two types of omega-3s that are most important for health.

Are there any potential side effects or risks associated with taking vegan alternatives to fish oil?

Like any dietary supplement, it’s possible to experience side effects from taking vegan alternatives to fish oil, such as digestive upset or allergic reactions.

However, these risks are generally considered low, and many people find that switching to a plant-based alternative to fish oil actually helps reduce their risk of certain health problems, such as heart disease and inflammation.

How do I choose the best vegan alternative to fish oil for my needs?

The best vegan alternative to fish oil for you will depend on your individual health goals and dietary preferences. For example, if you’re looking to boost your omega-3 intake specifically, you might choose an algal oil supplement that’s high in EPA and DHA.

If you’re concerned about getting enough vitamin D, you might choose a supplement that is fortified with vitamin D. It’s always a good idea to consult with a healthcare provider or registered dietitian to determine what supplement might be best for you.

Our #1 option from our testing is Future Kind’s Vegan Omega 3.


Omega-3 fatty acids are vital in achieving an optimal state of health. Fish oil supplementation could help fill the body’s omega-3 needs, but algae oil, a plant-based source of EPA and DHA, can offer more for everyone, especially vegans, vegetarians, and non-pescatarians.

When paired with an omega-3-rich diet and a healthy lifestyle, supplementation can reduce your risk of heart disease, support bone and joint health, and sharpen your cognition. 

The best vegan alternative to fish oil that we found from our extensive testing is the Vegan Omega 3 Supplement from Future Kind.

Make sure to choose a product that offers the best purity and transparency in ingredients.
