Vitamin D tablets 4000iu (100µg)

Essential Vitamin D supplement that offers the same result that would have been obtained from sun exposure, without exposure to sun rays.

Vitamin D regulates the amount of calcium and phosphate in the body, both needed for healthy bones, teeth, and muscles. It is found naturally in a small number of foods including oily fish, red meat, liver, and egg yolks and in fortified food like breakfast cereals and fat spreads. Vitamin D is also known as the sunshine vitamin because our bodies generally rely on our skin to make vitamin D from sunlight.

  • Help keep bones, teeth, and muscles healthy
  • Supports the immune system


Our High Strength Vitamin D tablets 4000iu contribute to the maintenance of normal bones, muscle function, teeth & immune system.

Vitamin D also contributes to normal absorption/utilisation of calcium and phosphorus, to normal blood calcium levels, and has a role in the process of cell division.

Public Health England recommends that everyone should consider taking a vitamin D supplement in winter and that people at greater risk of low levels should do so all year round.
