Special Nutrient

The one significant difference between Ensure and Boost Original is that Ensure contains 320 milligrams of omega-3 fatty acids, while Boost doesn't contain any. The American Heart Association recommends that you eat two servings of fatty fish a week, which is equivalent to 250 milligrams of omega-3 fatty acids.


Omega-3 fatty acids are essential nutrients you must get from the food you eat. Getting more in your diet helps reduce inflammation and may lower your risk of heart disease, arthritis and depression.
