Muscle Cramps

Can vitamin deficiencies cause muscle cramps?

Several vitamin deficiency states may directly or indirectly lead to muscle cramps. These include deficiencies of thiamine (B1), pantothenic acid (B5), and pyridoxine (B6). The precise role of deficiency of these vitamins in causing cramps is unknown.

Can poor circulation cause muscle cramps?

Poor circulation to the legs, which results in inadequate oxygen to the muscle tissue, can cause severe pain in the muscle (sometimes known as claudication pain or intermittent claudication) that occurs with walking or exercise. This commonly occurs in the calf muscles. While the pain feels virtually identical to that of a severely cramped muscle, the pain does not seem to be a result of the actual muscle cramping. This pain may be due to accumulation of lactic acid and other chemicals in the muscle tissues. It's important to see your doctor if you have pain like this.
