1. Rough, bumpy skin
Examine your skin closely. Do you have rough, bumpy skin, particularly on the back of your upper arms? If the answer is yes, then you may have keratosis pilaris, a skin condition that develops when you don’t get enough vitamin C.
This occurs because vitamin C is involved in the formation of collagen, a protein that keeps joints, skin, and bones healthy. Basically, a vitamin C deficiency translates as a collagen deficiency, which can lead to keratosis pilaris.
This skin issue occurs after approximately five months of low vitamin C intake. Luckily, once your doctor detects it, it can be treated with supplements.
Note: keep in mind that there may be other potential causes of keratosis pilaris. That’s why it’s very important to talk to your doctor first as she or he will know exactly what treatment you should follow.
