We have consistently recommended fish oils as one of the "must take" supplements for optimal health. Here is quick article from the highly respected Dr. Joseph Mercola on the benefits of fish oil.

------ Fish Oil ------

Unfortunately, I can't recommend fish because it is overwhelmingly contaminated with mercury and dangerous PCBs. What I can recommend, however--and I can't recommend it highly enough--is fish oil. Packed with beneficial omega-3 fats including DHA, fish oil:

• Helps fight and prevent heart disease, cancer, depression, Alzheimer's, arthritis, diabetes, ulcers, hyperactivity and many other diseases 
• Increases your energy level and ability to concentrate
  Provides greater resistance to common illnesses such as flu and cold
• Helps pregnant women avoid premature births, low birth weight and other complications

When using fish oil or krill oil it is important to obtain a high-quality reputable brand. In my research--and in my clinical experience with my patients--I have found that:

• The liquid form is superior to capsules 
• Certain brands definitely seem inferior to others 
• Those who live in more tropical environments with regular exposure to more intense sun will most likely be fine taking fish oil year round, as your vitamin D intake from the sun will be sufficient. If you aren't sure of what you should take, please have your vitamin D levels tested as it is possible to overdose on vitamin D.
