Evidence-based, peer-reviewed science shows, in the right population, adding long-chain omega-3 fatty acids to the diet can:
1) Improve memory, mood, and mental energy
2) Eliminate depression in adults and ADD/ADHD in children
3) Reduce the risk of Alzheimer’s
4) Reduce the risk of heart disease and inflammatory disorders
5) Promote better health and intelligence in children
DHA as present in supplements is fortunately very safe, inexpensive, and convenient to add to the diet. Even more, the exact amount of DHA added to the diet on a daily basis can be calculated, controlled, and delivered with scientific consistency. When it comes to the fish at the grocery stores, supermarkets or restaurants however—or even lakes, rivers, and streams in the USA—its now highly recommended that most sources of fish be avoided because of high concentrations of measureable toxins. In fact, the list of sources or varieties of fish to avoid consuming because of mercury and PCB contamination grows every year. The good news—there are certain varieties that are consistently lower in mercury and contaminants.
The healthiest and most contaminant free omega-3 rich sources of fish available today is wild Alaskan salmon, followed by wild Alaskan sockeye salmon, then sardines, and wild Alaskan haddock. The DHA in pure quality assured supplements is the best source of Omega-3’s to avoid contamination.
