Omega-3 Fish Oil Supplements: Beneficial, Harmful or Waste of Money?October 12, 2018 /
The bottom line
Because the evidence on fish-eating and various health benefits is strong, RDs should always take a food-first approach and work with patients to find ways to incorporate more seafood into their diet, with a goal of 2 to 4 ounce servings of fatty fish, such as salmon or sardines, each week. For those who do not or cannot eat fish, RDs should work with them to incorporate plant sources of omega-3s, such as walnuts, flax or hemp seeds, and leafy green vegetables.
Even though the evidence on using omega-3 from fish oil to reduce the risk of CVD is not as strong as once thought, it does not appear to have harmful effects for most people. Because there are potential benefits for other aspects of health, it seems wise to recommend a low dose of 1-2 grams/day for those who may benefit, with higher doses on a case by case basis.
As with other nutritional supplements, omega-3 supplements are not regulated by the FDA. Patients should be educated about how to choose higher quality supplements that are third-party verified or tested for quality and consistent dose.
