Vitamin E improved bone strength and bone minerals in male rats given alcohol

Objective(s): Alcohol consumption induces oxidative stress on bone, which in turn increases the risk of osteoporosis. This study determined the effects of vitamin E on bone strength and bone mineral content in alcohol-induced osteoporotic rats. Materials and Methods: Three months old Sprague Dawley male rats were randomly divided into 5 groups: (I) control group; (II) alcohol (3 g/kg) + normal saline; (III) alcohol (3 g/kg) + olive oil; (IV) alcohol (3 g/kg) + alpha-tocopherol (60 mg/kg) and (V) alcohol (3 g/kg) + palm vitamin E (60 mg/kg). The treatment lasted for three months. Following sacrifice, the right tibia was subjected to bone biomechanical test while the lumbar (fourth and fifth lumbar) and left tibia bones were harvested for bone mineral measurement. Results: Alcohol caused reduction in bone biomechanical parameters (maximum force, ultimate stress, yield stress and Young’s modulus) and bone minerals (bone calcium and magnesium) compared to control group (P
