Are vitamin supplements helpful after acl injuries?

Certainly: Vitamin supplements are an excellent source to balance our diet and prevent inadvertent deficiencies. However, it is not generally needed to help an acl heal. An acl generally cannot heal on its own, so no amount of supplementation will change that. After ran acl reconstruction, we are often deconditioned, so supplements can help.

Generally not.: If you're maintaining a healthy diet, and do not have any vitamin deficiencies, then vitamin supplements are of no value.
