Vitamin D plays a vital role in physical health, particularly in bone strength and immune system function. It aids in the absorption of calcium and phosphorus, essential minerals for maintaining strong bones and preventing conditions such as osteoporosis. Deficiencies in Vitamin D may lead to increased susceptibility to infections and certain chronic diseases. Additionally, research suggests that adequate levels of this vitamin may positively impact mood and mental health. Ensuring sufficient exposure to sunlight or consuming Vitamin D-rich foods is essential for maintaining optimum health.
