The body needs calcium for a number of functions including regulating blood pressure. Calcium could be found in the food we eat including in milk and in vegetables, as well as in supplements. If a person does not take enough calcium, the calcium is taken from the bones which can cause its thinning. The calcium needs to be taken from the bone because the other functions that are more important and urgent such as regulating nerve functions are calcium dependent.
Taking regular amounts of calcium ensures that your body has the calcium it needs for its functions. It also ensures that there is enough source for your bones to strengthen and for it to have enough density. Taking enough calcium is essential especially on a younger age, because this ensures that you have strong bones during the peak bone mass years (around the age of 30). Having strong bones during this time means that you are delaying the degenerative effects of age on the bones. Taking calcium and doing regular exercise (especially weight bearing exercise) are two good ways to prevent osteoporosis.
It’s not enough though to take just calcium. Vitamin D is an important component in the fight against osteoporosis because this is essential in allowing the body to absorb calcium. Calcium in its original form needs the help of the hormone calcitrol before it can be absorbed by our bodies. Calcitrol can only be produced with the help of vitamin D. In the absence of vitamin D, no matter how much our bodies take in calcium, we might still end up borrowing calcium from the bones.
Vitamin D is a vitamin that can be absorbed by the skin. This can be found in the body naturally after we are exposed to sunlight. Experts suggest taking in 15 minutes of sunlight every day, and this should be enough for us to store the vitamin D we need. Vitamin D is also present in food products such as eggs, fish and liver. It is important to note however that humans should not take in more than 800 IU of vitamin D because increased amounts can be harmful to the health.
