Calcium is the most abundant mineral in the body, with 99% per cent of it found only in our bones and teeth. The essential mineral helps in forming and maintaining strong bones and teeth, facilitating muscle movement and transmitting nerve signals. In addition, it aids in normal blood clotting and supports the proper release of hormones that regulate various bodily functions.Sources And Supplements Of Calcium Calcium is found in various food items including dairy, fortified foods, green leafy vegetables like broccoli, kale, collards, bok choy, and Chinese cabbage. While it is abundant in nature, some people may require supplements like calcium carbonate, calcium citrate, calcium gluconate, calcium lactate and calcium hydroxyapatite. When Should You Take Calcium? There is no particular time for calcium intake. According to a study published in the American Journal of Clinical Nutrition, researchers found no significant changes in the markers of bone formation in response to consumption of supolemetns taken at 9am to 9pm. However, it is important that a person should not be with an empty stomach. The food that a person eats releases an acid that is needed to break down calcium supplements. Moreover, if these supplements are taken with food, then it slows down the movement of this nutrient in the intestines. This allows more time for calcium to be absorbed. Why Do We Need Calcium?Bone Health: Approximately 99% of the body's calcium is stored in the bones and teeth, making it vital for their development, growth, and maintenance. During childhood, calcium is crucial for the formation of strong bones. Even after growth has ceased, it continues to play a significant role in preserving bone density and mitigating age-related bone loss. Muscle Contraction: Calcium is essential for muscle contraction. When a nerve activates a muscle, calcium is released, enabling muscle proteins to facilitate contraction. Conversely, when calcium is pumped out of the muscle, relaxation occurs. This regulation is key for overall muscle function.Cardiovascular Health: Calcium also plays a significant role in the cardiovascular system, particularly in blood clotting. Additionally, calcium is crucial for the heart's function and helps relax the smooth muscles surrounding blood vessels. Importance of Vitamin D: Vitamin D is indispensable for bone health, as it enhances the body's ability to absorb calcium. Together, these nutrients work synergistically to support overall health.Additional Benefits: Studies indicate that adequate calcium intake may lead to various health benefits, including a reduced risk of hypertension during pregnancy, lower blood pressure in adolescents, improved cholesterol levels, and a decreased likelihood of developing colorectal adenomas, which are benign tumours.
