Top 5 Most Common Vitamin Deficiencies and Their Symptoms

Vitamins play a critical role in many vital functions of the body, from energy production to immune system balance. Their deficiencies often manifest as early warning signs such as fatigue, skin problems, or weakened immunity. If ignored, these signals can lead to serious health problems in the long term. Here are the 5 most common vitamin deficiencies worldwide and their symptoms:

1. Vitamin D Deficiency: The “Sunshine Vitamin” Gap
