Arugula (Eruca sativa), also known as rocket, is a leafy green vegetable that contains several nutrients important for bone health, providing a scientific rationale for its support of the skeletal system. Arugula is particularly notable for its high content of vitamin K, which plays a crucial role in bone metabolism and the regulation of calcium in the body. Adequate intake of vitamin K has been linked to higher bone mineral density and a reduced risk of fractures, as it is necessary for the carboxylation of osteocalcin, a protein essential for bone mineralization.

In addition to vitamin K, arugula provides calcium, magnesium, and small amounts of vitamin C—all nutrients relevant to bone structure and maintenance. While arugula is not as calcium-rich as some other leafy greens, its calcium is relatively well-absorbed due to low levels of oxalates, which can inhibit calcium absorption in other vegetables.

However, it should be noted that the majority of scientific evidence pertains to the relationship between these nutrients and bone health in general, rather than direct clinical trials of arugula consumption and bone outcomes. Nonetheless, regular dietary inclusion of arugula as part of a balanced diet can contribute to the intake of bone-supporting nutrients. Thus, its use for bone health is scientifically supported, though mainly by extrapolation from its nutrient content rather than direct intervention studies.
