Nutrients beyond calcium and vitamin D have a role on bone health, and in treatment and prevention of osteoporosis. Quality and quantity of dietary fat may have consequences on skeletal health. Diets with highly saturated fat content produce deleterious effects on bone mineralization in growing animals. Conversely, dietary n-3-long chain polyunsaturated fatty acids play an important role in bone metabolism and may help in prevention and treatment of bone disease. Some reports suggest a correlation between the dietary ratio of n-6 and n-3 polyunsaturated fatty acids and bone formation. Specific dietary fatty acids were found to modulate prostanoid synthesis in bone tissue and improve bone formation in both animal and clinical trials. The skeletal benefits of dietary isoprenoids are extremely documented. Higher isoprenoids intake may relate to higher bone mineral density. Dietary supplements containing fish oil, individual polyunsaturated fatty acids, and isoprenoids could be used as adjuvant with bone medications in osteoportic conditions but their doses must be considered to avoid detrimental effect of over dosages.
