Omega-3 fatty acids are a type of polyunsaturated fat that plays many important roles in your body, including those involving inflammation, immunity, heart health, and brain function (
There are three main types of omega-3 fatty acids — eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linoleic acid (ALA).
EPA and DHA, which are primarily found in fish, are the biologically active forms of omega-3 fatty acids. Meanwhile, ALA is found in plant foods and must be converted into EPA and DHA before your body can use it (
For those who don’t regularly consume fish, taking a fish oil supplement can be a quick and convenient way to increase your intake of omega-3 fatty acids.
However, there are several factors to consider when finding the right fish oil supplement for you, such as the use of high quality ingredients and sustainably caught fish, third-party testing and certification, and EPA/DHA content.
Here are 10 of the best fish oil supplements.

There are several factors to consider when selecting a fish oil.
First, it’s important to check the ingredient list carefully and steer clear of supplements containing fillers or artificial ingredients.
Additionally, look for products that have undergone third-party testing and are certified by independent organizations like IFOS, USP, NSF International, or TGA.
Be sure to pay close attention to the dosage, including the amount of EPA and DHA. Some products may also contain ALA, which is a form of omega-3 fatty acids in plants that’s converted to EPA and DHA in small amounts (
For ALA, the daily recommended intake is 1.1 grams per day for women and 1.6 grams per day for men (8).
You may want to consider the source of the fish oil as well. Ideally, opt for smaller, sustainably caught fish like sardines and anchovies, which tend to contain lower levels of mercury (
There are also several forms of fish oil supplements, including softgels, liquids, or gummies. While some prefer the convenience and ease of capsules, liquids and gummies may work better for others.
If you experience nausea or vomiting after taking fish oil, check the expiration date, as the oil may deteriorate and become rancid. Consider taking the supplement with a meal to decrease any uncomfortable side effects.
