Brief summary

The objectives in this study are to provide information on the efficacy of transdermal supplement patches on treating nutrient malabsorption and deficiency in post-op bariatric patients, and to determine short-term body composition, HbA1c and fasting plasma glucose outcomes for patients after bariatric surgery.

Interventions

DIETARY_SUPPLEMENTChewable Multivitamin with Iron

Take daily: Chewable Multivitamin with Iron. The chewable vitamins, vitamin chew, or vitamin rapid/quick-melts can be consumed after surgery when cleared by the surgeon.

DIETARY_SUPPLEMENTPatchMD Vitamin D3/Calcium Patch

Wear daily: PatchMD Vitamin D3/Calcium patch. The patch can be worn immediately after surgery in order to prevent deficiencies, and we hope to show that this supplementation method can also promote lean muscle mass retention. In addition, due to the malabsorptive properties of bariatric surgery, we hope to show that patients will be more likely to completely absorb the micronutrient via transdermal application than through oral intake.

DIETARY_SUPPLEMENTChewable Calcium

Take daily: Chewable Calcium. The chewable vitamins, vitamin chew, or vitamin rapid/quick-melts can be consumed after surgery when cleared by the surgeon.

DIETARY_SUPPLEMENTQuick Dissolve B12

Take daily: Quick Dissolve B12. The chewable vitamins, vitamin chew, or vitamin rapid/quick-melts can be consumed after surgery when cleared by the surgeon.
