Simple version about calcium and muscle contraction

Updated: Sep 18, 2023

Did you know that if you engage in regular and intense exercise, it is essential to have enough calcium to support muscle contraction. During exercise, your muscles undergo repeated contractions and relaxations, which require an adequate supply of calcium. Intense physical activity can increase the demand for calcium in muscle cells.


If there isn't enough calcium available from dietary sources, the body may withdraw calcium from the bones to fulfill the immediate needs for muscle contraction. This can lead to a reduction in bone mineral density over time, potentially increasing the risk of bone-related issues such as stress fractures and osteoporosis. Maintaining an adequate intake of dietary calcium is essential for both muscle contraction and overall bone health.


So remember every time you contract a muscle, which if you like to exercise, that can be a lot of times a day, you need calcium! To support muscle contraction and maintain bone health, it's important to ensure an adequate intake of dietary calcium. Good dietary sources of calcium include dairy products (milk, cheese, yogurt), leafy green vegetables (kale, spinach), fortified plant-based milk alternatives, tofu, and canned fish with bones (such as sardines). If necessary, calcium supplements can also be considered, but it's advisable to consult with an accredited dietitian for personalized guidance on calcium intake and supplementation based on your specific needs.
