Another anecdotal account. I started practicing MMA and somehow in the first two month itself had minor fractures three times and not from doing something very dangerous. I was worried about my bone health, so I went to consult a doctor and he found my Vitamin D levels to be 9 IU. After supplementing for a few months the number shot up and I felt better overall(though this might have been just placebo effect).
