Buying Guide

Check EPA and DHA amounts

Look for supplements that list combined EPA and DHA per serving so you can compare actual omega-3 potency across products

Choose the form you prefer

Decide between softgels, liquid, flavored syrups or enteric-coated capsules depending on swallowing ease and taste sensitivity

Note purity and sourcing claims

Prefer products that state wild-caught or specific fish sources and reference re-esterified triglyceride (rTG) or purification processes for lower contaminants

Consider added nutrients

For children or multinutrient needs, check for added vitamins like A and D in cod liver oils or formulas designed for kids

Evaluate burp reduction features

If fishy aftertaste is a concern, look for burpless, flavored, or enteric-coated formulas marketed to reduce reflux and aftertaste
