What Are the Differences Between Fish Oil and DHA?

The differences between fish oil and DHA are mainly reflected in different components, clinical effects, and sources.

1. Different Components

The main components of fish oil are triglycerides, lipids, fat-soluble vitamins, and protein degradation products. The main component of DHA is docosahexaenoic acid.

2. Different Clinical Effects

DHA promotes brain development, maintains normal function of the nervous system, and has a certain protective effect on vision, especially crucial for fetuses during embryonic periods. It also enhances neurofunctional development and memory. Fish liver oil contains vitamin D, which promotes the absorption and utilization of calcium, benefits bone development, enhances bone hardness, and prevents rickets and osteomalacia.

3. Different Sources

DHA is widely distributed and can be found in breast milk, formula milk powder, deep-sea fish, seafood, egg yolks, algae, dried fruits, and more. Fish oil has a relatively single source and is mainly extracted from fish livers. Regardless of whether taking DHA or fish oil, one should consult a professional doctor based on their own condition to determine if it is necessary. Avoid self-medication or abuse to prevent adverse effects on the body.
