As a domain expert in nutrition, I can tell you that vitamin B-12 and folate, also known as vitamin B-9, are particularly important for oxygen transport in the body. Both of these vitamins play a crucial role in the production of red blood cells, which are responsible for carrying oxygen throughout the body. Vitamin B-12 aids in the creation of hemoglobin, the iron-containing protein within red blood cells that binds to oxygen. Folate is also essential for the synthesis of new red blood cells and for the maintenance of overall cellular health. To boost your intake of these vitamins, you can include foods rich in vitamin B-12, such as meat, fish, poultry, eggs, and dairy products, and foods high in folate, like citrus fruits and dark leafy greens. read more >>
