Hello; first, we need to assess how much vitamin D deficiency you have and how symptomatic you are with the deficiency.

• Serum 25-hydroxy Vitamin D levels <12ng/ml are considered severe, normal levels are between 20-50 ng/ml, and mild deficiency is considered anything less than > 20 ng/ml.
• People aged between 1 and 60 should get at least 15 mcg or 600 IU of vitamin D daily.
• Vitamin D is an essential nutrient for various reasons, particularly for bone health.

Causes of deficiency: Causes of vitamin D deficiency include insufficient sun exposure and decreased outdoor mobility during COVID and post-COVID times. Consumption of less nutritious food and food that is not rich in vitamins, as well as problems with absorption, can also lead to vitamin D deficiency. The application of sunscreens with high SPF can also be a reason for vitamin D deficiency.
