Vitamin D3 4000 – 120 softgels

OstroVit Vitamin D3 4000 IU comes in softgel capsule form, with each softgel delivering 100 µg (4000 IU) of cholecalciferol — the same form of vitamin D that the body produces through exposure to sunlight. The 120-softgel pack provides a four-month supply at one capsule per day. Softgels are an ideal format for a fat-soluble vitamin, as the oil-based fill supports absorption of the active ingredient.

Cholecalciferol is a fat-soluble compound found naturally in foods such as oily fish, and OstroVit’s formulation includes a fat source within the softgel to complement the active ingredient. Each capsule is small and easy to swallow, making the daily routine straightforward for those who prefer not to use powders or tablets.

This product is particularly well suited to adults with a higher requirement for vitamin D3, including those over 75, as well as people who spend limited time outdoors or follow dietary patterns that provide little of this micronutrient through food alone. OstroVit is a well-regarded European supplement brand known for consistent quality across its range.
