But getting the right amount of omega-3 isn't as easy as it might sound. You may be wondering about the differences between algae oil vs fish oil. Which is the best for boosting your omega-3 levels? And do certain people benefit more from one than the other?
We'll be looking into omega-3 and the key differences in the algae oil vs fish oil debate so that you can start purchasing the best fish oil supplements. For one, algae oil can offer a potential omega-3 alternative for those following a vegan diet. Read on to find out more.
What is algae oil?
You may have heard of algae oil, or algal oil, as a special omega-3 supplement. In fact, there are numerous algae oil products on the market, usually targeted at vegans.
Algae oil is typically used as an omega-3 supplement. Unlike fish oil, algae oil is made from marine algae, making it a suitable alternative for people who don't eat fish.
"Algae oil is exactly what it sounds like," says medical doctor Dr Laura Purdy (opens in new tab). "It is an oil that is extracted from certain algae."
Dr Laura Purdy is a board-certified family medicine physician who served in the United States Army for 14 years. She has worked throughout the medical field in both outpatient and inpatient capacities.
Purdy explains that algae oil is "nutritious and power-packed with omega-3 fatty acids". It is a great source of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), which are important omega-3 fatty acid variants.
"Fun fact," says Purdy, "the algal oil comes from the same microalgae that are commonly eaten by fish. Then through the digestion process, fish become enriched with the omega-3 fatty acids that they have consumed by eating the algae. So, in the end, the source of the omega-3 fatty acids is technically the same as the microalgae."
In other words, algae oil contains the same omega-3 as is found in fish oil supplements.
Is algae oil as good as fish oil?
According to Purdy, algae oil is as good as fish oil. "Because algae is a food source of the fish and is what fish oil is derived from, it is just as good to utilize algal oil as fish oil as a source of omega-3 fatty acids,” she says.
While fish oil may be the more popular supplement choice, algae oil is a fantastic alternative for vegans (or for people who dislike the taste of fish oil) as it contains the same fatty acids. Of course, not all supplements contain the same levels of omega-3 per serving size. With fish oils and algae oils, it’s important to check the label to ensure you’re getting the right amount of omega-3 per dose. If you’re unsure about how much omega-3 you require, it’s best to speak to your doctor to find out which specific supplement is the right choice for you.
What are other vegan sources of omega-3?
While algae oil is a great alternative for vegans looking to supplement their omega-3 intake, there are plenty of other options that offer omega-3. If you dislike the texture or taste of an oil supplement these foods are a great substitute.
Nuts and seeds
“Nuts and seeds are an excellent way to get omega-3 fatty acids, including chia, flax, and hemp seeds, walnuts, soy, and kidney beans,” says Purdy.
Create your own nut mix and keep it in the cupboard for when you need a snack, and your diet will be filled with extra omega-3. You could also put some chia or flax seeds into your morning smoothie (opens in new tab) to get an extra dose of omega-3 fatty acids.
Seaweed and algae
“Seaweed and algae are excellent sources, as are avocados,” says Purdy.
Try having sushi filled with avocado for an omega-3 boost if you’re a vegan. You can also try salted algae crackers; these are a great vegan snack and a little more fun than a spoonful or capsule of algae oil.
“Many green vegetables, such as brussels sprouts, spinach, kale and broccoli are also fantastic dietary sources,” says Purdy.
Even if you’re not a big fan of eating algae, there are lots of other green foods that offer omega-3; simply whip up a kale salad with some broccoli and you’ll get your daily dose.
While fish oil may be more popular than algae oil with supplement aficionados, as it turns out, algae oil is a perfectly acceptable substitute for vegans and plant-based eaters that offers the same nutritional benefits. Plus, many people may find that algae oil doesn’t have that off-putting fish taste that sometimes occurs with fish oil.
As always, we recommend speaking with your doctor before changing your diet or your supplement routine.
