Calcium Citrate Caps
People who are calcium deficient can have difficulty falling asleep. Also, some people with low calcium levels experience muscle cramps at night, which can occur even without any significant physical exertion during the day. Calcium has a sedative effect on the body. A calcium deficiency can cause restlessness and wakefulness.
Calcium citrate is the form of calcium that is more soluble than other forms of this mineral, such as calcium carbonate. Studies show enhanced absorption in this form.
