Calcium deficiency, phosphorus
deficiency and vitamin D deficiency Vitamin D is an important vitamin in the control of
calcium and phosphate levels in the body. The active formof vitamin D is necessary for the absorption of calcium and
phosphate from the intestine and for their incorporationinto bone
Low levels of vitamin D, calcium and phosphorus causemuscle aches and spasms, bone pain, and weakness. It also
lead to osteoporosis and osteomalacia

Osteoporosis and Osteomalacia The cause of Osteomalacia is usually insufficient of
Vitamin D which prevents the normal mineralizationof calcium and phosphorous to build strong bones
Osteomalacia usually reveals itself in aches and pain inlumbar region of the spine (lower back) and mayspread to arms and ribs
Osteoporosis occurs when calcium intake is not
sufficient or if the body does not absorb enoughcalcium from the die
Osteoporosis, usually has no symptoms until there is abone fracture.
