Your 2020 Guide For Finding The Right Fish Oil

Learn what to look for, plus the 3 biggest mistakes shoppers make when choosing a fish oil

Updated 03/28/2020

Fish oil has become a household name, and everyone knows how critical it is for supporting the health of your brain, heart, joints, skin, and more. In fact, your doctor has probably told you to try a fish oil at one point or another. 

Unfortunately, there are so many fish oils on the market that it's easy to assume a one-size-fits-all mentality and simply grab any brand off the grocery store shelf. Many of these products, however, won't provide the right nutrients, and in some cases, may hurt more than help

With that in mind, we decided to investigate the best and the worst fish oils. We'll show you what to look for, what to avoid, and the top mistakes buyers make when purchasing their supplements.

Choosing The Best Fish Oil Supplement For Your Needs 

The best omega-3 fish oil supplements are always formulated with natural sources and tested thoroughly for harmful or undesirable contaminants. 

Unfortunately, many brands don't live up to these standards, and shoppers don't realize they're buying a product that, at best, renders no results. Here are  some common mistakes made when purchasing an omega-3 supplement.

What Not To Do When Looking For A Fish Oil:

  1. Skip The Research

    Contrary to popular belief, not all fish oils are the same. Brands use different formulas, so check that they contain the ingredients below. 

  2. Rely On Amazon Reviews

    Up to 65% of Amazon reviews are written by paid individuals, and some of them might not have tried the product. 

  3. Prioritize Price Over Quality

    We found that the generic brands tended to fall short on potency. Focus on quality ingredients to avoid compromising on your health.

Reading the ingredient label is also essential when choosing a fish oil. That said, we compiled a list of what to look for, and what to avoid: 

Try To Look For:

  1. Large servings EPA/DHA, plus at least 500 mg to 1000 mg of fish oil
  2. A variety of omega-3 sources
  3. Natural lemon coating to help avoid fishy aftertastes

Try To Avoid:

  1. Mercury, PCBs, carrageenan, titanium dioxide

  2. Artificial colors, flavors, or additives

  3. Synthetic or unnatural ingredients

Fish oil is so popular that many of us already know the information above, so we've included some lesser-known tips:

3 Secrets For Finding A Quality Fish Oil

  1. Serving Size Is Crucial 

    The daily recommended fish oil serving size is about 800 mg, but for real effectiveness, try to find a formula offering 1000 mg to 2000 mg.

  2. Fish Oil Must Be Pure 

    Your fish oil must be unaltered and free of environmental or other undesired toxic elements. Third-party analyses can certify that the supplement passes these tests with flying colors.

  3. Get Maximum EPA and DHA

    The standard for EPA/DHA levels in fish oil should total a minimum of 500 mg per serving. Red flag: some fish oil supplements don't specify the exact levels of EPA and DHA in their product. 

The Results Are In...

After studying 97 different fish oil products, we've compiled our top three results. These products received the most positive reviews after we surveyed users and read reviews from over 7,000 consumers. They also have the strongest ingredients and decent guarantees.
