Unlike immune support supplements, which provide vitamins, minerals, botanicals, or other ingredients marketed around immune function, although immune effects are ingredient-specific and no broad supplement category can guarantee prevention, treatment, or cure of infection, heart health supplements supply fatty acids, sterols, fibers, minerals, botanicals, or other ingredients marketed around cardiovascular variables.
The useful distinction begins with different mechanisms. For heart health supplements, examine cardiovascular endpoint and formulation; for immune support supplements, examine immune function and nutrient status. Secondary features deserve weight once the direct job is understood.
