Natural Cholesterol Management

Nutrition can significantly improve your cholesterol levels, lowering LDL (bad) cholesterol by 30% or more, and raising HDL (good) cholesterol.

Foods containing plant sterol esters have been shown to lower serum cholesterol levels. According to the Mayo Clinic, "present evidence is sufficient to promote use of sterols and stanols for lowering LDL cholesterol levels in persons at increased risk for coronary heart disease."1 Plant sterol molecules actually block the body from absorbing cholesterol.2

Kardea bars combine the top nutrients for cholesterol management into one convenient and delicious natural snack.
