# Omega-3 fish oil

Compare EPA and DHA amounts, allergens and daily serving sizes.

**What you need to know**

Fish-oil products contain different amounts of EPA and DHA. The total fish-oil amount on the front of a pack is not the same as its EPA and DHA content. Compare the actual daily serving, and check any sustainability or purity claim against the supplier’s documentation.

This is an educational guide. Sanara is not taking orders or preorders. Compare the actual product’s label, suitability and total cost before buying from a retailer.

What to check before buying

## Check the label

- EPA and DHA separately per serving
- Fish allergens and capsule shell
- Evidence for sourcing and testing claims

## Directions and pack size

Use only as directed on the finished product’s label or patient information leaflet. Sanara has not verified a specific pack, dose schedule or supply duration for this guide.

## Safety

Contains fish. Not suitable if you are allergic to fish. Speak to a clinician if you take blood-thinning medication.
