What is Omega 3 Fish Oil?
Omega-3 fish oil supplements have been steadily gaining attention for their potential to support heart health, cognitive function, and overall well-being.
Sourced from oily fish like sardines, mackerel, and anchovies, these essential fatty acids—EPA and DHA—work to reduce inflammation and help maintain healthy cholesterol levels, making them a popular choice for those seeking an extra boost for their daily wellness routine.
Omega 3s Can Help With:
What To Look For In A Fish Oil Supplement
You want to look for at least 500 mg of EPA and DHA per serving of fish oil. These two omega 3 fatty acids are considered the most important components of fish oil because they deliver evidence-backed cardiovascular, cognitive, and anti-inflammatory benefits.
Make sure the product you select is actually made in the USA, where we have strict manufacturing quality standards. In addition, you want a supplement that is third-party tested, by an independent laboratory. This will help ensure high quality and safety.
Look for a supplement that undergoes third-party testing by an independent laboratory. This extra layer of verification can help confirm both quality and safety.
Try to choose a fish oil supplement that offers a 100% money-back guarantee. Look for brands that offer at least a 60-day money-back guarantee.
What To Avoid
Avoid fish oil supplements that contain unnecessary additives, fillers, or artificial ingredients. These can dilute the potency of the supplement and may cause adverse reactions in some individuals.
Beware of any supplements that claim their product treats or cures any specific disease or ailment, or promises miraculous, unrealistic, or misleading results. Always speak to your doctor before starting a new supplement routine.
Selecting the cheapest rather than the best quality can potentially do you more harm than good. If brands don’t identify certain ingredients or nutrients and their amounts in each dose, you could end up with an ineffective or potentially harmful supplement.

A
OVERALL GRADE
PROS
- Tested for impurities.
- Sustainably sourced.
- Lemon flavor.
CONS
- Some customers dislike the smell.
- 640 mg omega 3 compared to 720 mg.
Nordic Naturals is a respected name in the fish oil supplement market, known for their sustainable sourcing, third-party testing, and pleasant lemon flavor—qualities that have helped them build a strong reputation over the years.
Their formula delivers 640 mg of omega-3 per softgel, and the recommended serving size is two softgels taken at once, which some experts feel may be less optimal than splitting the dose for improved absorption.
Additionally, while the lemon flavor aims to minimize the fishy aftertaste, a number of customers report that the scent still lingers.
Overall, Nordic Naturals provides a reliable omega-3 option backed by reputable testing and sustainable practices.
However, if you prefer a higher per-softgel dosage or a split-serving regimen, this product’s design might not be the best fit. The lingering smell is also something to keep in mind if you’re particularly sensitive to odors.

TOTAL RANKING
B+
OVERALL GRADE
PROS
- Sold on popular marketplaces.
- Third-party tested.
- Sustainably sourced.
CONS
- Can be dosed only once a day.
- Large softgels may be difficult to swallow.
- Fishy odor.
Sports Research is another popular brand in the omega-3 market, offering a potent 1040 mg of omega-3 per softgel, sustainably sourced from wild Alaska Pollock.
They also undergo third-party testing for heavy metals, which is reassuring for safety and quality-conscious consumers.
However, these high-dose softgels can be quite large and difficult to swallow, and because they don’t include any added flavoring, you may notice a strong fishy smell upon opening the bottle.
Additionally, the product is recommended as a once-daily dose—an approach some experts feel is less optimal than splitting your fish oil intake for potentially better absorption.
Despite these drawbacks, Sports Research maintains a loyal following thanks to its robust potency, sustainable sourcing, and testing standards.
