Once you’ve sent your sample to our UK-accredited partner laboratory, results and advice from our doctors will be ready in 2 to 3 days. How to Order

Vitamin D is essential for a human body to work as it should. It’s present in some foods, and plays an important part in keeping bones strong.

Vitamin D regulates the amount of calcium and phosphate in your body – nutrients which are needed for healthy teeth, bones and muscles.

Please note: where a generic product has been ordered we may use a range of manufacturers to provide you with your medication, in order to maintain our service levels.
