How to read the differences

Start with the serving.

The details below describe what labels can tell you, not a product ranking or evidence of performance. Confirm the exact product and version in the linked sources.

Check the format

Softgels, gummies and liquids are different formats. A label amount for one version should not be assumed to apply to another.

  • NOW Foods DHA-500 Fish Oil, Double Strength Softgels: Softgels
  • Wiley's Finest Wild Alaskan Fish Oil Peak DHA: Softgels

Find the stated serving

Look for the quantity and unit beside Supplement Facts. Two labels can list amounts per different numbers of softgels or different liquid measures.

The table flags unknown or mismatched bases rather than silently converting them.

Read EPA and DHA separately

EPA and DHA are components of omega-3s. Their calculated sum, when both are sourced for the same serving, is not necessarily the product’s total omega-3 amount.

A missing or unverified amount is not treated as zero.

Follow the evidence

Use the source links and any checked dates in the table to review the exact format, serving and current package. Price, availability, allergens and other label details can change.

Your questions guide the comparison.

Use the table to examine the information, then review each product’s complete label and sources. No single figure establishes that one product is preferable for every person.
