Vitamin D3 (cholecalciferol) is produced naturally in the skin in response to sunlight, but in the UK, the sun is only strong enough to produce meaningful vitamin D between roughly April and September. The NHS recommends that adults consider supplementing with at least 10mcg (400IU) of vitamin D daily during autumn and winter, with many people benefiting from higher doses based on their individual needs.
Our High Strength Vitamin D3 delivers 4,000IU (100mcg) per tablet — a substantial daily dose used by many people who have tested low or who want robust year-round levels. The cholecalciferol used is extracted from lanolin, the same natural source the body uses to produce its own vitamin D.
