Vitamin K
Vitamin K is needed for proper bone formation and blood clotting. In both cases, vitamin K does this by helping the body transport calcium. Vitamin K is used by doctors when treating an overdose of the drug warfarin (Angelo). Vitamin K also helps to prevent and fight osteoporosis, a disease that affects more than 25 million Americans (Booth). Adults ages 18 to 44 who take in about 1 mg per 2.2 pounds of their body weight per day of vitamin K have proper bone formation and consequently decreasing their chances of Osteoporosis. In a study including 148 people testing bone mineral density was examined and they had a vitamin K intake, those with lower bone density had a mean vitamin K intake of 161 ug per day; those with higher bone density took 217 ug per day (Weber 882). Vitamin K is a fat-soluble vitamin essential for the production of prothrombin and several other proteins involved in the blood clotting system, and the bone protein osteocalcin. Deficiency causes impaired blood coagulation and haemorrhage.

Experimental and placebo-controlled studies in humans should clarify our understanding of the role vitamin K plays in improving bone health (Weber 885). “The role of vitamin K supplementation is of greatest interest in patients with cholestatic liver disease, both because these patients are at greatest risk for malabsorption of fat-soluble vitamins due to luminal bile acid deficiency and because osteoporosis is a significant problem in this population. However, recent evidence suggests that even patients with viral cirrhosis may abnormal bone turnover and increased risk of osteoporosis” (Lipkin 787). “Vitamin K positively influences calcium balance, a key material in bone metabolism” (W
