Omega-3 Fatty Acid Supplements
Omega-3 fatty acids (ALA, EPA, and DHA) are important nutrients. There is a wealth of data in the medical literature about the cardiovascular benefits of omega-3 supplements. Omega-3 supplements have been shown to reduce the risk of sudden cardiac death and heart attack, slow growth of plaque in the arteries by decreasing inflammation, improve lipid levels, enhance blood pressure regulation, and reduce pulse pressure.1-5 Because of these benefits, the American Heart Association recommends eating 2 servings of fatty
fish weekly - but is this really the healthiest way to get your omega-3s?
Should we eat fish to get our omega-3s?
Fish is an unfavorable source of omega-3s because most fatty fish contain harmful pollutants, such as dioxin and mercury. People also report difficulty digesting fish oils because of the fishy taste and rancidity. Purified fish oils are an option, however the increased demand for fish and fish oils is depleting our oceans of fish.6,7 Algae-based DHA+EPA is a more sustainable option, and it is free of the environmental pollutants that accumulate in fish. Also, since pregnant women are advised to limit
fish intake (to avoid the potential harm of mercury to the baby's brain), supplemental omega-3 fatty acids are a safer alternative.
Omega-3s don’t only help the health of your heart – here are some additional benefits:
- Important for pregnant/nursing women and children, to ensure proper fetal and childhood brain and vision development.8-12
- Reduced risk of ADHD and other childhood cognitive disorders.13,14
- Improved memory; reduced risk of Alzheimer's disease and cognitive decline in the elderly.15-17
- Reduced risk of depression.9,18,19
- Omega-3 fatty acids and Parkinson's disease (PD): A number of animal studies have shown that DHA has preventive and/or therapeutic effects against PD.20-22 I have seen PD in a surprising number of elderly men that eat healthy vegan diets, and I have also observed that all these men were DHA-deficient. Since men convert ALA to DHA less efficiently than women, prevention of Parkinson's disease with DHA supplementation may be important for non-fish eating men.
How to maintain adequate omega-3 levels healthfully:
- Take 1 tbsp. of ground flaxseed each day
- Include additional plant sources of the omega-3 fatty acid ALA
(walnuts, hempseeds or hemp milk, and chia seeds) in your diet regularly
- Since only a limited amount of ALA can be converted to EPA and even less to DHA, take an algae-derived DHA supplement.
