In the past, hundreds of studies have been conducted to determine the health benefits of taking multivitamins. Some studies have produced evidence of positive health benefits, and other studies conducted within the past year have resulted in a positive correlation between taking proper supplements and reduced risk for cardiovascular disease.
Calcium’s Role in the Cardiovascular System
Calcium triggers the contraction of muscle cells as an action potential—the nerve impulse and stimulus to muscular tissue—results in release of calcium into muscle tissue sarcomeres. Following the impulse and resulting contraction, the tissues resorb calcium, and the process starts over. When all of the cardiac cells work together, it produces the force necessary for driving blood through the chambers of the heart. Additionally, the same processes occur within the arteries. However, dramatic increases in calcium storage can result in excess calcium remaining within the cardiac and smooth muscle tissue in the heart and blood vessels. Unfortunately, this results in a lower calcium threshold for triggering the contraction.
What’s a Safe Range For Multivitamin Minerals?
Multivitamins, which are classified as supplements, are not regulated by the Food and Drug Administration (FDA). This means manufacturers do not have any set standards for ensuring proper combinations of minerals, vitamin, or other compounds within the product. However, it does prevent the addition of medications to supplements. The simplest way of ensuring calcium does not become excessive is by speaking with a physician about current cardiovascular heart health. This includes obtaining lab results of potassium, calcium, and other elements within the blood. Creatinine Kinase (CK), an enzyme identifier for excess cardiac stress, should be checked periodically when taking multivitamin mineral supplements as well.
Multivitamins and Antioxidants
Several vitamins, such as vitamin A and vitamin E, are known antioxidants. In many supplements, mineral and vitamins are combined together to provide optimal benefit to the body. Antioxidants function to reduce how free radicals, or unattached oxygen atoms, affect bodily tissue. When an unpaired oxygen atom comes into contact with living tissue, it causes damage to the tissue in a manner similar to frost bite during the winter. When taking a multivitamin, it needs to contain antioxidants as well as potassium and calcium. However, if heart disease and other cardiovascular problems are present, taking a multivitamin should only be encouraged with a physician’s approval.
Multivitamins can be beneficial to heart health, but you have to ensure you are not taking too much of them.
