What it is
Essential fatty acids (EPA, DHA, ALA) needed for heart and brain health.
Why depends
Fish oil and krill oil are animal-derived. Algae oil is the original source — fish only contain EPA/DHA because they eat algae.
What a “Depends” verdict means
A 'depends' verdict means the same ingredient name covers both plant and animal sources, and the label alone cannot tell you which one is in the tub. Certification, an allergen statement, or a direct answer from the manufacturer is the only reliable way to settle it.
Where you'll find it
- Fish oil supplements
- Cod liver oil
- Fortified milks and juices
- Krill oil

How to read the label
Omega-3 (Fish Oil) belongs to the other ingredients family. These are the terms worth scanning for on any ingredient list in this category:
- Natural flavouring
- Processing aid
- Anti-caking agent
- Carrier
- Glazing agent
- Identify the function first, then the plausible feedstocks.
- Check for a vegan trademark before attempting to decode the ingredient.
- Email the manufacturer — source-of-origin questions get answered.
- Prefer brands that publish an ingredient-origin policy.
Mistakes to avoid
| Where it catches people out | What to do |
|---|---|
| Imported products | Ingredient sourcing differs by market even within the same brand and packaging. |
| Reformulations | Recipes change without fanfare; re-check products you buy rarely. |
| Own-brand supermarket goods | Made by rotating contract manufacturers, so sourcing can vary batch to batch. |
Other ingredients in context
Some ingredients do not fit a neat family: industrial chemicals with animal feedstocks, multi-purpose compounds, and materials that cross between food, cosmetics and household goods.
The rule of thumb is to identify the function of the ingredient first. Once you know what job it does — emulsify, glaze, colour, thicken, preserve — you can predict which feedstocks are plausible and which certification would answer the question.
When the label cannot resolve it, the manufacturer usually can. Brands answer source-of-origin questions readily, and a written reply is worth more than a forum post.
Does certification help? When an ingredient's origin cannot be read off the label, a recognised vegan trademark is the only scalable answer, because certifiers see supply-chain documentation that consumers never do.
