Vita-K 'n' Kids Study II

Study Description: Vitamin K is a 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 the body's use of lipids (fats) and glucose (sugar). Understanding the role of vitamin K in the body's use of lipids and glucose may help develop preventive strategies and early interventions to reduce obesity-related disorders such as dyslipidemia and type 2 diabetes. The purpose of this study is to determine if taking two capsules daily of vitamin K supplement for two months can improve levels of lipids (fat), glucose (sugar), and other measures in blood associated with dyslipidemia and diabetes risk. 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.
