The condition is characterized by pain in the pelvic region, limbs and spine, with increasing weakness of affected bones. In adults, and especially in women, osteomalacia is caused by a Vitamin D deficiency.
Unlike other vitamins, Vitamin D is rarely found in food. Small amounts are contained in fish liver oil, beef liver and eggs. However, your main source of Vitamin D is direct exposure to sunlight, which stimulates pro-vitamins already present in the skin to synthesize Vitamin D. If you cannot get outdoors enough, or if your skin is very dark, Vitamin D supplements may be necessary (consult a doctor to be sure).
Vitamin D regularizes calcium and phosphorous metabolism, both of which are essential for maintaining healthy bones and teeth.
