Micronutrients & recovery
Correcting vitamin D insufficiency (levels < 30 ng/mL) may be warranted to prevent greater quadriceps muscle loss and support genomic recovery processes after ACL reconstruction.
Have your Vitamin D levels checked after ACL surgery. If they are below 30 ng/mL, correcting this insufficiency may help reduce quadriceps muscle loss and support recovery, though its impact on functional outcomes is less clear.
ModerateQualifiesLOW confidence
Those with vitamin D below 30 ng/mL experienced greater quadriceps muscle loss up to 4 months post‐surgery, while genomic analyses indicated vitamin D influences genes related to muscle recovery
Why this rating
Based on two observational studies with mixed results on functional outcomes but clear association with muscle loss in one.
