A healthy heart is crucial to a healthy lifestyle. Time Warner Cable News’ Kristen Shaughnessy spoke to one of the country's top cardiologists to get some advice on what you can do and what supplements you should take to keep your heart healthy. She filed the following report.

Five supplements play a key role in keeping your heart healthy.

"Everybody should be taking what I call ‘The Big 5,’” says Dr. Dennis Goodman, Director of Integrative Medicine at NYU Langone Medical Center.

Goodman says start with a methylated multivitamin.

"The best multivitamins are methylated, which means that they actually have a way they can be used better in the body for the enzyme systems," he says.

The next two, Vitamin D3 and Vitamin K2, are often combined in a bottle labeled “Calcium + MenaQ7.”

"Really important for keeping calcium in the bones where it needs to be and away from the arteries. And it should be in the form of MenaQ7," says Goodman.

To figure out how much Vitamin D to take, you need to know your Vitamin D level – which you can get through the 25-hydroxy vitamin D blood test.

"Vitamin D is extremely important for helping to absorb calcium, but once the calcium gets in the body you want to make sure it gets to the right place," says Goodman.

A magnesium deficiency puts you at greater risk for heart disease and stroke, so Dr. Goodman checks the red blood cell magnesium level on all his patients, and finds most are deficient.

"Magnesium is an essential mineral not made by the body. It is extremely important. It is used in over 350 enzyme systems in the body and people that are magnesium-deficient are often fatigued, muscle cramps, palpitations. It’s associated with anxiety and depression,” says Goodman.

Magnesium supplements are not for people with kidney problems, but in other patients, he has had good results. Goodman suggests taking 3 milligrams per pound.

"They feel so much better. They don't have muscle cramps, they sleep better," says Goodman.

His final recommendation is a form of fish oil called krill oil, which is less controversial.

"Krill oil is the best way to get your omega-3s, because it has a phospolate inside it, which helps it to be absorbed," he says.
