Your 2021 Guide For Finding The Best Fish Oil

What to look for and what to avoid in a quality supplement + our top 3 picks of the year

Updated 03/04/2021

fish oil gel caps on scaleNot long ago, omega-3 fish oil was a little-known supplement, popular among health enthusiasts and those "in the know." Today, you can find it practically anywhere you look, from pharmacies to convenience stores and online retailers.  

That's why, when it comes to shopping for a fish oil supplement, it's easy to assume a one-size-fits-all mentality. However, not all fish oil supplements are created equal, and with so many products on the market, it can be hard tell apart the good from the bad. 

At Consumer Survey, we're here to cut through the noise. After analyzing dozens of the most competitive fish oils on the market, we put together this informative guide to help you find one that's right for you. 

Read on to learn what to look for and what to avoid in your supplement — plus, find out which top 3 fish oils made our 2021 list. 

Omega-3 Fish Oil Supports:

  • Heart and joint health
  • Immune function 
  • Memory and mood
  • Cognitive health
  • Weight management 
  • Healthy cholesterol levels

Choosing The Best Fish Oil Supplement For Your Needs 

The best omega-3 fish oil supplements are always sourced from high-quality, wild-caught fish that have not been treated with hormones and have been tested thoroughly for harmful contaminants.

Quality supplements will also contain effective levels of omega-3 fatty acids, including EPA and DHA. Unfortunately, not all companies are bound by the same standards, which is why some brands are able to compete despite having inferior quality fish oil.

Here are a few tips on what to look for and what to avoid in an effective omega-3 supplement.

Your Quality Control Checklist

EPA and DHA 

EPA and DHA are the most beneficial types of omega-3 fatty acids present in fish oil. 

Most health experts recommend a minimum daily allowance of 250–500 mg of EPA and DHA for healthy adults, and often recommend higher doses as needed depending on an individual's health conditions.

Third-Party Tested

Check to make sure the fish oil you select has been third-party tested. Supplements that undergo third-party testing are independently vetted for purity and potency and help promote transparency in labeling.

Lemon Oil

Lemon oil helps neutralize fish odor in the gut, preventing residual fish odors from resurfacing. Look for a product that includes lemon flavoring or lemon oil. 

What To Avoid:

  1. Misleading Labels

    "Fish oil" and "omega-3s" are often used interchangeably, however, they're not exactly the same. While fish oil contains omega-3s, like EPA and DHA, not all fish oils contain them in the same concentrations.

    Look for products that clearly label the amounts of EPA and DHA (at least 250 to 500 mg per serving).

  2. Amazon Reviews

    Millions of Americans look to Amazon reviews before purchasing their products, but most don’t realize that up to 60% are written by individuals paid to leave positive feedback.

    Risking your health with reviews that are likely false is too dangerous a game to play when you’re choosing an ingestible supplement.

The Results Are In...
