Yes - absolutely.
Calcium is needed for muscle and nerve function and a lot of other processes.
youll get brittle bone didease and your teeth wont be as strong
There are many ways including getting older, not intaking enough calcium and not intaking enough vitamin D.
Calcium is a necessary part of human biochemistry, and no living person has no calcium ions in their body.
weaken your bones
Yes, calcium is essential for maintaining healthy bones and teeth, as well as for muscle function, nerve signaling, and blood clotting. Without enough calcium, the body can suffer from conditions like osteoporosis and muscle cramps.
Without enough calcium in the body, you may experience symptoms such as muscle cramps, numbness or tingling in the fingers and toes, weak and brittle bones, and an increased risk of fractures. Severe calcium deficiency can lead to conditions like osteoporosis or rickets.
If you don't eat the right amounts or types of food. For example, not having enough iodine could cause your thyroid to enlarge. That could be a form of malnourishment.
*Calcium maintains healthy red blood cells. Calcium is part of a functioning of the nervous system. Calcium is important in blood clotting. Calcium helps forms and maintain bones and teeth.
Vitamin D is needed for calcium to be made useful in the body (for instance in bones). As you get older you tend to lose calcium from the bones and it becomes necessary to try and prevent this by ensuring that there is enough calcium in the diet and that this calcium is usable by the body. Vitamin D is made in the body by the action of UV sunlight on the fat layers just under the skin. If there is not enough exposure to sunlight the body becomes short of vitamin D and bode deformities can occur in growing children (rickets). Therefore in the young and the old it is important that both Calcium and vitamin D are present in the diet.
The body continually needs calcium to replace calcium lost in bone and in teeth. There is no age at which the body "stops accepting calcium". Instead, women who do not exercise (weight bearing exercise), do not consume milk products, do not get enough sunshine, etc. can experience problems with the body being able to use calcium and Vitamin D to make new bone. Then teeth and bone become "brittle" and more apt to break or disintegrate.
A lack of calcium leads to osteoporosis, among many other things, which is the condition of having brittle bones. When the body is deprived of calcium, it will take calcium from the bones by breaking them down. If the body continues to be deprived of calcium, the bones will not be rebuilt like they normally would. Instead they will just be broken down even further. When a person eats and drinks foods and liquids with the proper amount of calcium for their body, their body doesn't have to break the bones down for the calcium because it already has a sufficient supply.
Yes your body does need calcium because if your body doesn't have calcium it would decrease your bone strength.
