Essential Amino Acids and Vitamin D might prove to be a safe and easy way to improve recovery after knee replacement surgery.
One study found that 2 grams of essential amino acids (protein available OTC) daily for 1 week prior and 2 weeks after surgery will improve your recovery.
Additionally, some basic science research has suggested Vitamin D in the peri operative period may lower the infection risk.
These are two good ideas that are not harmful and may benefit my patients.
