You’ve likely heard by now that omega-3’s are a must-have in just about any wellness routine.
Heavily researched and studied for their whole body-supporting benefits, these essential healthy fats are crucial to human development and healthy aging, as well as cognitive, heart, joint, skin, and overall health.*
That’s why more and more people are now turning to fish oil supplements as a way to safely and effectively get all the daily omega-3s they need for vibrant health.*
Omega-3: Why Everybody Can Benefit
- Since your body cannot produce omega-3 on its own, these crucial healthy fats must be consumed through diet or supplementation.*
- Most individuals’ diets are sorely lacking in this healthy fat, despite it being essential to every area of human health. Studies suggest that supplementation in addition to food sources may need to be considered to help American adults meet recommendations.* [1]
- There are 3 main types of omega-3 fatty acids: DHA, EPA, and ALA. These are essential components in the brain. DHA, in particular, makes up a large percentage of the omega-3s in the brain and is thought to be important for supporting brain health. [2]
All Fish Oils Are NOT Created Equal
With a saturated market containing thousands of fish oil supplement options, choosing the right high-quality omega-3 product can seem pretty daunting.
So how can you be sure that you’re investing in a quality fish oil supplement that will actually satisfy your needs?
When choosing a fish oil supplement, there are some things you may want to consider:
What To Look For In Fish Oil Supplements
- EPA & DHA content: Ideally, a high-quality fish oil supplement should contain at least 500mg of DHA and EPA combined for maximum efficacy. Always avoid products that don’t include the exact amounts of DHA and EPA on the label, as this may be a big red flag.
- Fresh from the source: Fish oil supplements can become ineffective and potentially harmful when they sit on store shelves for extended periods of time. It’s always best to purchase your fish oil directly from the source whenever possible through a reputable online shop to avoid expired or rancid products.
- Third-party lab testing: It’s especially important that your fish oil supplement has been independently lab tested and verified to be free from any heavy metals (like mercury) or other toxic contaminants, with certificates of analysis available upon request. This way, you can rest assured that the product you choose is the purest, safest, and most transparent option possible.
What To Try To Avoid In Fish Oil Supplements
- Misleading or extreme claims: Always beware of misleading fish oil supplements promising miraculous or unrealistic overnight cures.
- Unclear labels: It’s a good idea to avoid omega-3 supplements (and any nutritional supplement) that don’t clearly list the ingredients included.
- Unwanted ingredients: Try to avoid fish oil products that include cheap artificial ingredients, such as synthetic fillers, binders, artificial colors, and synthetic flavoring. (A short list of 'Other Ingredients' can typically be a good sign.)
- Suspiciously cheap or expensive products: Don’t risk your health or waste money on suspiciously low-cost fish oil supplements that may contain cheap hydrogenated oils and lack proper safety testing, serving sizes, and potency.
- Heavy metal contamination: Steer clear of vague labels lacking third-party lab testing and transparency, as these fish oil products may contain trace elements of toxins, heavy metals, bacteria, or other contaminants.

Bottom Line:
Ultimate Omega is an omega-3 supplement by Nordic Naturals that contains 1460 mg EPA, 1010 mg DHA. This quality supplement is to be taken as a liquid at 1 teaspoon per day. However since this is a liquid formula the taste and smell of fish oil even with a lemon flavor may not fit every users needs. This formula also does not include vitamin E and only comes with a 30-day return policy.
PROS
- 2840 mg Omega-3s per serving
- Lemon flavor
- Third-party tested
CONS
- Taken as a liquid, ease of use
- 30-day return policy
Bottom Line:
OmegaXL is a fish oil supplement that contains omega-3s from green-lipped mussel oil harvested in New Zealand. Like some other products featured, this formula also combines omega-3s with vitamin E and comes in softgel form. However, at two softgels taken 2-3 times daily, the serving size is one downside as it can be inconvenient to incorporate as part of a daily routine.
PROS
- Includes vitamin E
CONS
- Serving size
- Omega-3 content
Bottom Line:
Triple Strength Omega-3 by Sports Research is a one-a-day omega-3 supplement that features 690 mg of EPA and 260 mg of DHA from wild Alaskan Pollock. This omega-3 formula comes in a handy serving size of 1 softgel per day, is third-party tested in a GMP facility, and comes with a 90-day return period. However, some may want to note that although it has both DHA and EPA, the formula only includes 260 mg of DHA.
PROS

- Wild Alaska Pollock Fish Oil Concentrate

CONS
- 260 mg DHA
Bottom Line:
Nature’s Bounty Fish Oil is a solid option for an affordable omega-3 supplement. It contains both EPA and DHA fatty acids and is made and third-party tested in the USA. The formula comes in a softgel form. However, it’s good to be aware that the daily serving size may be fairly inconvenient to some as users are recommended to take 1 softgel 3 times a day with meals. This would mean having to always carry the product along whenever eating out.
PROS
- DHA and EPA
- Includes other fatty acids
- Third-party tested
CONS
- No vitamin E
- Serving size
