Vitamin D: Why it’s needed, signs of deficiency, and how to take it correctly

Vitamin D is a fat-soluble vitamin that plays a critical role in maintaining bone health, immunity, heart function, and even mood. It's also known as the "sunshine vitamin" because it's synthesized in the skin when exposed to ultraviolet light.

The main functions of vitamin D:

• Regulates calcium and phosphorus metabolism, strengthening bones and teeth

• Supports the immune system

• Improves mood and fights depression

• Supports heart and vascular health

• May reduce the risk of certain cancers and autoimmune diseases

Signs of Vitamin D Deficiency

Vitamin D deficiency is a common problem, especially in regions with low sunlight exposure. More than 70% of Russians have insufficient levels of this vitamin, especially in the fall and winter.

The main symptoms of vitamin D deficiency:

• Chronic fatigue and drowsiness

• Frequent colds and decreased immunity

• Bone and muscle pain

• Bad mood, irritability, depression

• Hair loss

• Problems with sleep and concentration

If you notice these symptoms, it's worth getting your vitamin D blood tested. The normal range for adults is 30 to 100 ng/ml .
