Calcium and Vitamin D Supplements Fail to Cut Fall or Fracture Risk in Seniors, Study Finds
A new meta‑review in The BMJ examined 69 randomized trials involving 153,902 adults aged 65 and older and concluded that calcium, vitamin D, or their combination do not reduce falls or fracture risk.

New Research Finds How to Execute the Perfect Carb Load
Researchers at Liverpool John Moores University tested three two‑day carbohydrate‑loading protocols (6, 8 and 10 g per kilogram body weight) against a 4 g/kg baseline in 11 trained endurance athletes. Muscle biopsies showed a linear increase in leg‑muscle glycogen with higher carbohydrate intake, with the 10 g/kg regimen delivering the greatest storage. The study found no significant weight gain, gastrointestinal distress, or other adverse effects at the highest intake. Findings suggest that a two‑day, 10 g/kg carb load is safe and more effective than lower protocols.
