Vitamins A, D, and E are essential for bone health, wound healing, and inflammation reduction during orthopaedic and other procedures.
To prevent interfering with anaesthesia or raising the risk of bleeding, some supplements, such as vitamin C, may need to be stopped before surgery.
Before and after surgery, always get personalized advice from a healthcare professional about the vitamins and supplements you need.
