As per another study, vitamin K not only increases bone mineral density but also reduces fracture rates. Dietary intake of 90 micrograms of vitamin K per day for females and 120 micrograms of the nutrient per day for males are recommended. Insufficient consumption of iron and zinc also may lead to osteoporosis and collagen depletion.

Bok choy contains vitamin C, an antioxidant known for its role in collagen production and combating free radicals. It may help reduce the risk of skin damage caused by external factors. It may also help fight the signs of aging such as fine lines and wrinkles. However, limited data is available in this regard.

Additionally, bok choy provides other essential nutrients like folate and vitamin B6 that are crucial for red blood cell production. Including bok choy in a well-balanced diet may contribute to managing anemia and promoting overall well-being.
