There are some common signs we can take note of. Firstly, slow wound healing. This would often point to a lack of vitamin C. Secondly, an unusual case of hair loss could also be due to a lack of vitamin B12. Lastly, if you often feel tired, it could be due to a lack of vitamin D.
For instance, vitamin C helps in the growth and repair of tissues in our body, and speeds up wound healing process by forming scar tissues to protect them. Vitamin C also helps in the absorption of iron.
Vitamin B assists with red blood cell production, and help boost our energy and metabolism. It also plays an important role in building a healthy nervous system.
Vitamin D helps our body absorb and retain calcium and phosphorus, which are crucial in bone building. It also helps to control infections and reduce inflammation.
