Biography Dr. Kyla Shea is Scientist I in the Vitamin K Laboratory at the HNRCA. Her research focuses on the role of micronutrients in age-related disease and disability. In particular, Dr. Shea evaluates the role of vitamin K and D in osteoarthritis, the leading cause of disability in older adults. She also examines the relationship between vitamin K nutritional status and cardiovascular disease. Dr. Shea discovered that adults with sufficient vitamin K and D levels have better leg function than adults with sufficient levels of either vitamin alone, suggesting these two nutrients may be mutually beneficial to joint and/or muscle health. She also determined that low vitamin K status is associated with higher cardiovascular disease risk in people with high blood pressure. This may indicate vitamin K is important for people more likely to develop heart disease. Dr. Shea’s current research focuses on the relationships among vitamin K and D, arterial stiffness and heart disease in people with chronic kidney disease and high blood pressure. She is a member of the American Society of Nutrition and the American Heart Association.
