The amount of Omega-3 a person needs depends on their age, sex, and health status. If a person does not eat fish on a regular basis, then taking an Omega-3 supplement might be a good idea.

- eicosapentaenoic acid (EPA)
- alpha-linolenic acid (ALA)
There are few guidelines for recommended intake of Omega-3s for different people to achieve optimal health or dietary needs for certain health conditions or simply said, the recommended amount a person needs to ensure nutritional adequacy.

During pregnancy and lactation periods, women should follow a supplementation regimen as follows:
- 0.3 g of EPA plus DHA, of which at least 0.2 g should be DHA

For babies up to the age of 1 year, the infants should consume 0.5 g of total Omega-3s from human milk that contains ALA, DHA, and EPA.
