Study Arms:
- Vitamin B6 Effects in OC Users (Type: EXPERIMENTAL): All subjects will be given an infusion of labeled serine, methionine and leucine prior to vitamin B6 supplementation and after 28 days of treatment. In addition, they will receive a special diet 2 days prior to the infusion and will have weekly weight, blood, and visits to the clinic.~The results from analysis of vitamin B6 and these amino acids in blood will provide us with specific measurements of the rates of two aspects of metabolism (Primary Outcomes 1 and 2) and specific measurements of vitamin B6 nutritional status (Primary Outcomes 3 and 4).

Based on this trial design, predict the completion outcome and termination type (if applicable).
