Micronutrients & recovery

Higher blood concentrations of 25-hydroxyvitamin D (25[OH]D) are associated with lower risks of fracture in observational studies, but this association is not replicated when using vitamin D supplementation alone in randomized trials.

Don't rely on Vitamin D alone to protect your bones. While people with naturally high Vitamin D levels have fewer fractures, taking Vitamin D supplements by themselves does not reduce fracture risk. You need to combine it with Calcium to see benefits.
