Does anyone know what nutrients are needed for healing?

[Mdguy]

Biochemistry experts, I've been on Keto Diet quite a few times and currently now on one. I've noticed that during these diets, muscle and ligament sprains seem to be very stubborn to heal for me. Has anybody found this to happen to them also? Are carbs or any other nutrients essential for muscle repair to occur more quickly?

Any insights would be appreciated. Thanks.
