Our verdicts
The Very Finest Fish Oil (Liquid)
The best liquid fish oil we reviewed: a potent 1,300 mg EPA+DHA per teaspoon, IFOS certification, sustainable sourcing and a flavor that even fish-oil skeptics tolerate. You have to refrigerate it and finish the bottle within 100 days, so it rewards daily users rather than occasional ones.

Ultimate Omega
Ultimate Omega earns its reputation with a meaningful 1,100 mg EPA+DHA dose, triglyceride-form oil, published lot testing and some of the best tolerability feedback in the category. You pay a premium for the name, and it lacks IFOS certification, so value-focused buyers can match the dose for less. If taste and brand track record matter most, it remains a safe, well-made choice.
