Complete Surgical Nutrition (CSN) is a clinician-founded company committed to accelerating recovery and improving surgical outcomes by simplifying evidence-based nutrition. Developed by a team of internationally recognized surgeons who have collectively cared for over 50,000 patients, CSN’s mission is to make optimal surgical nutrition accessible to everyone through a streamlined and research-backed system.
At the heart of the offering is the Surgical Nutrition Kit, a comprehensive bundle that features OptiFuel—each packet delivering 25 grams of high-quality whey protein enriched with leucine and glutamine—and OptiCharge, a specialized complex carbohydrate drink designed for intake the night before surgery. The kit includes a branded shaker bottle and comes in one-, three-, or six-month supplies. It is manufactured in an NSF-certified facility in the USA, gluten-free, non-denatured, and eligible for HSA/FSA spending.
CSN emphasizes a science-informed approach rooted in clinical evidence: patients are encouraged to begin supplementation one to two weeks prior to surgery, continuing through the recovery period for several weeks to months. This regimen supports muscle preservation, enhanced healing, and improved recovery trajectories.
