Study Description: The objective of this study is to determine if taking two capsules daily of vitamin K supplement for eight weeks (two months) can improve markers in blood associated with diabetes risk. Vitamin K is a fat-soluble vitamin found mostly in leafy green vegetables (e.g., spinach, broccoli, kale, and collards) and in soybean oil and canola oil. Vitamin K is necessary for normal blood clotting and may be needed for other activities such as normal glucose metabolism. Understanding the role of vitamin K in glucose metabolism may help develop preventive strategies and early interventions to reduce obesity-related disorders such as type 2 diabetes. If your child meets all criteria and agrees to participate, he/she will be one of 60 participants, aged 8 to 17 years, taking part in this study.

Augusta University is required by law to report any payments we make to the Internal Revenue Service (IRS). To do this, you will need to complete a W-9 form and provide your name, address, date of birth, research study name and social security number. Payment will be made using the Greenphire ClinCard. It works like a bank debit card. We will give you a debit card and each time your child receives a payment for participation in this study, the money will be added to the card after each completed visit. This card may be used at any store that accepts credit cards or can be used at a bank machine to remove cash. However, there may be fees drawn against the balance of the card for cash withdrawals and inactivity. You will receive letters with additional information on how you can use this card and who to call if you have any questions. Be sure to read these letters, including the cardholder agreement, for details about fees. An outside company administers the debit card system. The company, Greenphire, will be given your child?s name and social security number. They will use this information only as part of the payment system. Your child?s information will not be used for any other purposes and will not be given or sold to any other company. Greenphire will not receive any information about your child?s health status or the study in which he/she is participating.
