What is the role of ALA in the body?
ALA is known to be a source of energy for the body, and while it is converted into DHA and EPA, it is not yet definitively known how efficiently the body is at this conversion. Current research shows the body may only convert 5-10% of ALA to EPA and even less, only .01-5%, to DHA, so a person should not rely on ALA as a primary source of omega 3 fatty acids. No research has indicated a direct role in cardiovascular or retinal health from ALA, but it plays an indirect role in the conversion to the long-chain fatty acids. While some studies have even shown a potential link in the progression of late-stage prostate cancer and macular degeneration additional research has also suggested potential neuroprotective effects of ALA in in-vivo models of both global ischemia and KA-induced epilepsy.
