Vitamin D & B12 are the vital nutrient components which, just like protein, calcium, fat, and water, act as a significant element for the growth and development of human body.  Vitamin Deficiencies usually lead to diseases like rickets, scurvy, and beriberi.From the past few years, it has been noticed that due to an increase in erratic lifestyles, urban youth has shown an increasing occurrence of vitamin deficiency such as Vitamin D & B12. Let’s study about the reasons, symptoms, and corrective measures of Vitamin D &B12 in urban youth. Hence the importance of Vitamin Testing is important in the current era.

Vitamin D – deficiency of Vitamins

Vitamin D, also known as the Sun Vitamin is produced through the process of synthesis inside the human skin due to direct exposure to the sun. The main function of Vitamin D is bone growth. It fosters the process of calcium absorption in the gut. Vitamin D is also required for other processes like neuromuscular and immune operation and modulation process in cell growth. It is estimated that one billion people around the world are suffering from Vitamin D deficiency.

With increasingly long hours spent indoors, the youth is showing higher numbers of Vitamin D deficiency. This is compounded by the fact that whatever little time we spend outside, we are covered by sunscreen, which prevents our skin from converting sunlight to Vitamin D.


  1. Low or no exposure to sun
  2. Limited outdoor activities
  3. Wearing too much sun block creams to prevent the process of synthesis.
  4. Obesity due to consumption of unhealthy and junk food
  5. Maintaining an unhealthy lifestyle during aging years.
