I am no medical expert, but does vitamin c help improve bone strength?
It is not clear. However, some physicians advocate Vitamin C megadosing to treat certain conditions, poisonings, or to facilitate recovery from trauma.
I did not know that. That seems like a pretty important set of procedures. Vitamin C is in orange juice right?
Yes, if you ever find yourself in a situation where you want to avoid scurvy, eating oranges (which contain Vitamin C) is a good idea.
