The authors found that concentrations of magnesium and zinc were significantly…

Calcium supplementation improves bone health

Summary This research explored the question of whether intake recommendations for calcium are sufficient to maintain bone health. For this purpose, the study authors collected data on calcium intake recommendations. Based on their analyses the researchers concluded that current calcium intake recommendations (ranging between 600 mg and 800 mg calcium per day) are too low.…

Green tea protects against bone loss

Summary This study investigated the effects of green tea on bone loss. The experiments were performed using 20 female rats.
