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.*

Since your body cannot produce omega-3s 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]

PROS

Includes vitamin E

CONS

Serving size
Omega-3 content

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.

2. Ultimate Omega

by Nordic Naturals

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

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.

4. Triple Strength Omega-3

by Sports Research

PROS

690 mg EPA
Wild Alaska Pollock Fish Oil Concentrate
Made in the USA
1 softgel daily

CONS

260 mg DHA

BOTTOM LINE

Triple Strength Omega-3 by Sports Research is a one-a-day omega-3 supplement that features 690mg of EPA and 260mg 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.

by Nature Made

PROS

Pros 600 mg EPA and DHA
Purified to remove mercury and contaminants

CONS

30-day money-back guarantee (shorter than top-ranked options)
Low price raises concerns about quality and potency
No added vitamin E to prevent oxidation

BOTTOM LINE

Nature Made Fish Oil is a heart health support supplement providing 720 mg of Omega-3 fatty acids (600 mg EPA and DHA combined) per two-softgel serving. We like that it has been purified to remove contaminants. However, the 30-day money-back guarantee falls short compared to the 90-day policy of top-ranked options. In addition,the low price point raises questions about the quality of ingredients and thoroughness of safety testing. Additionally, the lack of added vitamin E is a notable omission, as this antioxidant helps prevent the fish oil from oxidizing and becoming rancid. As the fifth-ranked option in our Top 5 Fish Oils list, it's a budget-friendly choice from a well-known brand, but potential compromises in quality, potency, and stability make it a less compelling option compared to higher-ranked alternatives.

Primal Omega-3 by Primal Harvest is a premium fish oil supplement that features 750 mg marine lipid oil, 600 mg of EPA, 400 mg of DHA, and 4 mg of vitamin E. This omega-3 formula comes in easy-to-take softgels with no fishy aftertaste. The convenient serving size of two softgels per day makes this omega-3 fish oil supplement easy to add to any wellness routine.

As all high-quality supplements should be, Primal Omega-3 is third-party lab tested and made in the USA with globally sourced ingredients. Primal Omega-3 is sold at a fair price and the brand has a convenient Subscribe & Save program which means you can order this formula through their convenient and hassle-free subscription service.

CITATIONS

DISCLAIMER: This scientific research is for informational purposes only. The results reported may not necessarily occur in all individuals. Primal Harvest provides this information as a service but does not endorse it. This information should not be read to recommend or endorse any specific products.

Note: Individual results may vary. The benefits stated are based on personal experiences and subjective feedback and may vary from person to person.

Misleading or extreme claims: Always beware of misleading marketing tactics, ‘Amazon-only’ products, and 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 state the quantities of the ingredients included.
Unwanted ingredients: Try to avoid omega-3 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 hazardous toxic materials, heavy metals, bacteria, or other contaminants.*

EPA & DHA content: Ideally, a high-quality omega-3 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.
Fresh from the source: Fish oil supplements in particular 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.
