Mammals are unable to synthesize omega−3 fatty acids, but can obtain the shorter-chain omega−3 fatty acid ALA (18 carbons and 3 double bonds) through diet and use it to form the more important long-chain omega−3 fatty acids, EPA (20 carbons and 5 double bonds) and then from EPA, the most crucial, DHA (22 carbons and 6 double bonds).

Fish oil is widely sold in capsules containing a mixture of omega−3 fatty acids, including EPA and DHA. Oxidized fish oil in supplement capsules may contain lower levels of EPA and DHA. [46] [47] Light, oxygen exposure, and heat can all contribute to oxidation of fish oil supplements.
The longer-chain EPA and DHA are only naturally made by marine algae and phytoplankton. [4] [5] The microalgae Crypthecodinium cohnii and Schizochytrium are rich sources of DHA, but not EPA, and can be produced commercially in bioreactors for use as food additives. [88] Oil from brown algae (kelp) is a source of EPA. [89]
Omega−3-carboxylic acids are used in addition to changes in diet to reduce triglyceride levels in adults with severe (≥ 500 mg/dL) hypertriglyceridemia. [6]Intake of large doses (2.0 to 4.0 g/day) of long-chain omega−3 fatty acids as prescription drugs or dietary supplements are generally required to achieve significant (> 15%) lowering of triglycerides, and at those doses the effects ...

There is generally a pattern of more DHA than EPA in most of these products. For example, Nordic Naturals reports per serving DHA 390 mg and EPA 195 mg (total omega−3 = 715 mg), Calgee reports DHA 300 mg and EPA 150 mg (total omega−3 = 550 mg) and so on, but iwi Life reports DHA 100 mg and EPA 150 mg (total omega−3 = 252 mg).
