Things You'll Need
Exercise regularly. Your body needs more oxygen when you exercise. Therefore, exercising on a regular basis sends messages to your body to increase red blood cell count. This allows your body to deliver a larger amount of oxygen during subsequent exercise sessions.
Make sure you consume proper levels of iron. Hemoglobin relies heavily on iron to help transport oxygen to your cells, so not having the proper iron levels decreases red blood cell count. Normal iron levels will vary according to age and sex.
Consume the proper levels of Vitamin B-12 and folate. These compounds are important in the production of red blood cells. Thus, if you want to increase red blood cell count, you won't want to skimp on the fish and fortified breads. As with iron, proper vitamin B-12 and folate levels vary according to age and sex.
Train at higher altitudes. Oxygen is less abundant at higher altitudes, so your body's natural response is to increase the number of red blood cells. Doing this increases the amount of oxygen that can be delivered to your body's cells.
