Brief Summary
Patients undergoing bariatric surgery often develop new vitamin and/or mineral deficiencies or exacerbate prior deficiencies after surgery. Several bariatric supplement products exist including oral tablets and transdermal patches. The purpose of this study is to observe the concentrations of serum micronutrients and determine how many deficiencies develop in patients who use a transdermal patch.

Study Arms (1)
Participants with transdermal patches
All study subjects will belong to the same group. This group will undergo bariatric surgery and will use a transdermal patch for vitamin and mineral supplementation post operatively. The transdermal patch will be the Patch MD MultiVitamin Plus patch
Interventions
The transdermal patch contains vitamins A, D, E, K2, C, thiamine, riboflavin, niacin, pantothenic acid, pyridoxine, biotin, folic acid, cyanocobalamin, calcium, iron, phosphorous, iodine, magnesium, zinc, selenium, copper, manganese, chromium, molybdenum, potassium, chloride, and boron.
