Quick answer: Algal DHA and fish-oil DHA are chemically the same nutrient, but algal DHA is vegetarian, free of fishy taste and ocean contaminants, and more sustainable. Fish oil is cheaper and widely available, but algal DHA suits vegetarian and eco-conscious families better.
Both deliver the same DHA molecule — the difference is source, purity and values.
Key takeaways
- Algal DHA: vegetarian, no fishy taste, low contaminant risk
- Fish oil: cheaper, widely available, animal-derived
- Sustainability favours algae
For vegetarian and Indian family diets, algal DHA is the natural fit.
