This study is an extension of an earlier study of vitamin D supplementation conducted on normal weight individuals by Dr. John Aloia of the Bone Mineral Research Division at Winthrop University Hospital. The investigators plan to compare the response to vitamin D supplementation in obese individuals with the response already measured in normal weight individuals. The same dosing schedule of vitamin supplementation will be used as in the past. The doses used in the past have demonstrated safety in a number of trials, here at Winthrop as well as outside of Winthrop Hospital. Sixty study volunteers are planned for enrollment in the study. The study participants will mainly be recruited from a group of patients who have in the past been enrolled in the weight loss program at Winthrop Hospital. Each participant will be on vitamin D supplementation for a total of 8 weeks. Vitamin D blood levels will be measured before and at the end of the supplementation period. They will then be compared to see the change over time as a result of supplementation.

A lipid cofactor that is required for normal blood clotting. Several forms of vitamin K have been identified: VITAMIN K 1 (phytomenadione) derived from plants, VITAMIN K 2 (menaquinone) from bacteria, and synthetic naphthoquinone provitamins, VITAMIN K 3 (menadione). Vitamin K 3 provitamins, after being alkylated in vivo, exhibit the antifibrinolytic activity of vitamin K. Green leafy vegetables, liver, cheese, butter, and egg yolk are good sources of vitamin K.
A nutritional condition produced by a deficiency of VITAMIN D in the diet, insufficient production of vitamin D in the skin, inadequate absorption of vitamin D from the diet, or abnormal conversion of vitamin D to its bioactive metabolites. It is manifested clinically as RICKETS in children and OSTEOMALACIA in adults. (From Cecil Textbook of Medicine, 19th ed, p1406)
OXIDOREDUCTASES which mediate vitamin K metabolism by converting inactive vitamin K 2,3-epoxide to active vitamin K.
A condition of having excess fat in the abdomen. Abdominal obesity is typically defined as waist circumferences of 40 inches or more in men and 35 inches or more in women. Abdominal obesity raises the risk of developing disorders, such as diabetes, hypertension and METABOLIC SYNDROME X.
A family of phylloquinones that contains a ring of 2-methyl-1,4-naphthoquinone and an isoprenoid side chain. Members of this group of vitamin K 1 have only one double bond on the proximal isoprene unit. Rich sources of vitamin K 1 include green plants, algae, and photosynthetic bacteria. Vitamin K1 has antihemorrhagic and prothrombogenic activity.
