Maintaining an optimal balance between "good" (HDL) and "bad" (LDL) cholesterol is key when it comes to healthy heart function. While there is a genetic component to your cholesterol, the right diet, lifestyle choices and supplements can help. Here are some tips for keeping already-healthy cholesterol levels in check.

1. Easy heart-healthy foods

   Say so long to excessive added sugars, saturated and trans fats and processed foods—all of which can throw your levels out of whack. Instead, opt for whole grains, beans, and fresh fruits and vegetables, which are mainstays of the Mediterranean based diet. Plus, foods rich in omega-3s will help keep your cholesterol levels within a normal, healthy range.

2. Get moving

   Physical activity has been shown to greatly support already-healthy cholesterol management; moderate physical activity helps raise your "good" HDL levels. It's important to incorporate at least 30 minutes of activity each day, so make sure you stick with something you enjoy: running, rowing, biking, swimming, tennis and even golf are great ways to break a sweat!

3. Supplement smartly

   Diet and exercise are great building blocks for maintaining already-healthy cholesterol levels; essential, heart-healthy nutrients will fill in any gaps. Look for nutrients like artichoke extract, which has been clinically studied to help maintain healthy HDL and LDL levels. Pantethine, a derivative of vitamin B5, has been shown to help maintain already-healthy cholesterol levels. And no heart-healthy regimen is complete without CoQ10, which has the added bonus of revving your cellular energy levels!
