What is Colecalciferol used for?

Vitamin D3 Lek is often recommended for individuals with limited sun exposure or dietary intake. It may also be used to support immune function and muscle strength.

What are the side effects of Colecalciferol?

Vitamin D3 Lek helps regulate calcium and phosphate levels in the body, contributing to normal bone mineralization. Many users report improved energy levels and mood with adequate vitamin D intake. Some individuals may experience mild digestive effects when first starting supplementation. Consistent use supports overall vitamin D status over time.

High doses of vitamin D may interact with medications affecting calcium metabolism, such as thiazide diuretics. Some anticonvulsants, like phenytoin, may reduce vitamin D effectiveness.
