Advantages of Vitamin D and Calcium Essay

Calcium is an essential mineral that develops and maintains healthy bones. It also helps in blood clotting, muscle contraction, and beating of the heart. Bones and teeth contain nearly all the calcium in the body. Humans shed calcium through skin, nails, hair, sweating, urine, and feces daily. The human body is unable to generate calcium on its own. That is why it is essential to acquire enough calcium from the diet. When people do not receive enough calcium, the body may take it from their bones. It is all right occasionally, but if it happens frequently, bones become weaker. Vitamin D aids calcium absorption in the body. So, even if people consume enough calcium, it could be wasted if they are vitamin D insufficient.

Peak bone mass is generally reached by the age of 31. Thus, physical exercise and taking the required calcium and vitamin D dosages through adolescence and adulthood will help ensure peak bone mass development.

Calcium is a vital component of the body and is essential for various cell processes. It is crucial not only for bone health but also for neuromuscular activity, blood clotting, and appropriate heart function and is an integral part of bone architecture and is essential for bone mineral deposition throughout life. Although the body stores more than 99.2% of the calcium in the teeth and bones, calcium is also present in plasma.

Plasma calcium levels determine calcium balance. When plasma levels drop, bone resorption rises to compensate for the decrease. Calcium intake must be sufficient to protect this balance. Vitamin D enhances the assimilation of calcium into the small intestine. Excretion of calcium is highly occurring through kidneys; however, there is some fecal loss. The best method to satisfy the dietary requirement is to eat foods that are high in calcium.

Because of their high elemental calcium concentration, high absorptive rate, and low cost, dairy products are the most suitable calcium sources. In addition, dairy products and various green vegetables are excellent sources of calcium in the diet.

Vitamin D
Vitamin D is a crucial mineral for preserving healthy bones. Vitamin D’s prominent roles are to control intestinal calcium absorption and to promote bone resorption, resulting in the maintenance of calcium levels.

Sunlight, diet, and supplementation are all suitable sources of vitamin D. Most Americans do not have enough vitamin D in their bodies. It is believed that 89% of people between the ages of 52 and 72 do not have adequate vitamin D from their food. Utilization of vitamin D happens by sun exposure, which causes its synthesis in the skin. Previtamin D3 will form when ultraviolet B radiation from the sun is entering the skin. Heat quickly converts previtamin D3, an unstable molecule, to vitamin D3. Vitamin D3 is pulled into the capillaries by vitamin D-binding protein as it travels out into the extracellular space.

Then transferring of vitamin D to the liver occurs via the capillaries. It is then hydroxylated to generate 25-hydroxyvitamin D. DBP binds 25-hydroxyvitamin D and transports it to the kidney. Afterward, it is released and hydroxylated to generate 1, 25-dihydroxy vitamin D in the renal tubule cell. It is the physiologically active version of vitamin D that helps the body manage calcium levels.

The absorbance of vitamin D occurs into the lymphatic system through chylomicrons, where it binds by DBP before entering the bloodstream. They are then transported to the liver and kidneys, where the active vitamin D will form, as previously stated.

Calcium and vitamin D are the very essential nutrients for bones. Lack of these can lead to bone disorders. Osteoporosis is a prevalent bone disease that results in a decrease in bone density and mass over time. Bones become thin, fragile, and quickly shattered as a result. Every year, more than 1.2 million osteoporotic fracture cases occur in the US. Particularly in the spine, hip, and forearm around the wrist. Various treatments are available to prevent bone loss and treat low bone density. However, the initial treatment for osteoporosis is to consume calcium-rich foods and beverages that also include vitamin D, which helps in calcium breakdown and absorption. Good nutrition is necessary at all ages to maintain the bones stronger.
