Frequently Asked Questions (FAQs)

1. Is docosahexaenoic acid the same as fish oil?

Don't confuse DHA with EPA. They are both in fish oil, but they are not the same. DHA can be converted into EPA in the body in very small amounts.

2. Is it better to take fish oil or DHA?

DHA supports brain health If your goal is to dampen or prevent inflammation—aches, pain, swelling—then standard fish oils or a fish oil with more EPA may be desirable. However, if you want to improve brain function, then consider a fish oil with a higher concentration of DHA.

3. What is DHA in fish oil good for?

Docosahexaenoic acid (DHA) is an omega-3 fatty acid essential for brain development during pregnancy and early childhood. It is also linked to improved heart health, better vision, and reduced inflammatory response.

4. Is fish oil high in DHA?
