Algae Oil: Algae Oil vs. Fish Oil

When you think of algae, the first thought that comes to mind is the green, soft layer that develops on top of ponds, lakes, and other sea objects. But did you know this green film can actually be grown in a lab too? 

Surprisingly enough, algae are actually considered an organism which includes 40,000 species from microalgae to seaweed. All of these algae rely on energy from sunlight or ultraviolet (UV) light and carbon dioxide.[*] 

Like fish oil, algae oil is jam-packed with omega-3 fatty acids (omega-3s). What are omega-3s?

Omega-3 Fatty Acids

Omega-3s are a family of polyunsaturated fats found in a variety of different plants and fish. Omega-3s are considered essential fatty acids. This means that your body can’t make them on its own, so you have to obtain them via diet.

There are several types of omega-3s including but most of the research today focuses on EPA, DHA, and alpha-linolenic acid (ALA).

Omega-3s aren’t stored in the body to be used for energy but instead, they play many important roles in the biological process within the body such as proper function and structure of cell membranes, regulating inflammation, and proper function of your heart and immune system. 

They also make compounds called signaling molecules, which help regulate inflammation and aid various parts of your body, including your heart and immune system.[*][*]

Both algae oil and fish oil are strong sources of omega-3s, but how are they different?

Algae Oil vs. Fish Oil

All fish (both wild and farm-raised) get their omega-3s from consuming algae.[*][*]

One study showed that supplementing with algae oil had a similar effect as consuming salmon in your diet.[*] Another study showed that supplementing with 600 mg of DHA from algae oil a day raised blood levels the same as taking DHA from fish oil.[*]

The biggest difference between algae oil and fish oil is that because it’s grown under controlled conditions, algae oil is free from toxins that may be present in fish oils.[*] Algae oil also seems to cause less stress on the digestive system, therefore causing fewer burps and stomach upset. It also has a more pleasant taste compared to the “fishy” taste of fish oil.[*]

Health Benefits of Algae Oil

Supplementing with algae oil has a number of benefits. Some of the benefits of this oil include:

• May support heart health[*]

• May reduce depression[*]

• May benefit eye health[*]

• May reduce inflammation[*]

The Take Away

Algae oil provides the same benefits as fish oil, but it may be a better option for individuals who follow a plant-based diet, or if you want to avoid the taste or aftereffects of fish oil.

Taking algae oil may improve your heart health, eye health, cognitive health, and could help fight off any inflammation as well.
