What are Vitamins? | Why Do We Need Vitamins? | Complete Basic Information
Vitamins are micronutrients that help perform important functions in our body. The most essential nutrients needed by our bodies are. Vitamin A, C, D, E, K, and a group of B complex vitamins. Vitamin A is required to make a pigment called Rhodopsin in our eyes. Rhodopsin helps us to see in low light conditions. Thus, without vitamin A, rhodopsin won’t be produced, causing night-blindness. Vitamin C and E are antioxidants. Unstable free radicals damage our cell’s DNA. Leading to illness or cancer. Vitamin C and E neutralize free radicals, preventing cell damage. Vitamin D helps our body absorb calcium to build strong bones. Thus, a lack of vitamin D can lead to a condition called rickets. Which is characterized by weak, soft bones. During an injury, vitamin K helps the blood clot. Thus preventing excessive bleeding. Lastly, B complex vitamins are essential for healthy functioning. Of our brain and nervous system.
