When the body lacks sufficient vitamin C, the gum tissue may become weak and inflamed, and the blood vessels may start bleeding more easily. This can lead to the gums appearing red, swollen, and bleeding (Olmedo et al., 2006). Moreover, the gums may even take on a purplish hue in severe cases of vitamin C deficiency. Unhealthy gums can also affect the integrity of teeth over a prolonged timeframe (Larralde et al., 2007) (Fain, 2005a). Therefore, ensuring adequate vitamin C intake through a balanced and nutritious diet is crucial.
5. Painful Swollen Joints
Did you know that your joints contain a lot of collagen-rich connective tissue, which can also be affected by vitamin C deficiency? You must get enough vitamin C to keep your joints healthy and functioning correctly (Tamura et al., 2000).
6. Poor Immunity
Vitamin C is essential for obtaining a healthy immune system, which may increase the risk of severe infections like pneumonia (Johnston et al., 2014). Scientific studies suggest that vitamin C accumulates inside different types of immune cells, enhancing their function and aiding them in fighting diseases and destroying harmful pathogens (Carr & Maggini, 2017).
It is worth noting that people with scurvy, a condition caused by vitamin C deficiency, often suffer from a weakened immune system. If not treated promptly, this can result in a higher susceptibility to infections and, worse, fatalities (Pimentel, 2003a). An adequate amount of vitamin C in your diet is recommended to maintain a healthy immune system.
7. Iron Deficiency Anemia
There is a notable link between vitamin C and iron deficiency anemia. Low levels of vitamin C can contribute to iron deficiency anemia by reducing iron absorption from plant-based foods and negatively affecting iron metabolism (Teucher et al., 2004) (Lane & Richardson, 2014). Additionally, vitamin C deficiency increases the risk of excessive bleeding, which can lead to anemia (Agarwal et al., 2015).
If you are experiencing iron deficiency anemia without any apparent causes, it is recommended to check your vitamin C levels.
