“When it will come to making use of vitamin and mineral health supplements, specially calcium health supplements staying taken for bone overall health, several Us citizens feel that extra is often greater,” mentioned Erin Michos, M.D., M.H.S., associate director of preventive cardiology and affiliate professor of medication at the Ciccarone Middle for the Avoidance of Coronary heart Illness at the Johns Hopkins College University of Medicine.

Experts also knew that as a person ages, calcium-primarily based plaque builds up in the body’s main blood vessel, the aorta and other arteries, impeding blood circulation and raising the threat of coronary heart attack.
