Description
BioTechUSA Vitamin D3 50mcg provides 2000 IU of vitamin D3 per tablet — a meaningful daily dose for UK adults where limited sunlight makes vitamin D insufficiency extremely common throughout the year. Vitamin D3 is the most bioavailable form of vitamin D, identical to that produced by the skin in response to sunlight.
At 50mcg (2000 IU) this sits between a basic maintenance dose and a therapeutic dose — appropriate for most adults as a consistent year-round supplement, and particularly important during autumn and winter months when UK sunlight is insufficient for skin synthesis entirely.
Key Benefits:
- 50mcg (2000 IU) Vitamin D3 per tablet
- Supports normal immune function
- Contributes to healthy bones, teeth and muscle function
- Supports mood and mental wellbeing
- Essential for UK adults with limited sun exposure
Take one tablet daily with a meal containing fat for optimal absorption. Can be taken year-round.
