To get a treatment, fill in a brief medical questionnaire. A doctor will review and prescribe treatment if it’s right for you. For test kits, you can just place an order. 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.

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. These nutrients are needed for healthy teeth, bones, and muscles.

Please note, when you request a generic (non branded) treatment, the product you receive may look slightly different than what we show on our website. The active ingredient in the medication will be exactly the same though. This is because we use a range of manufacturers to ensure we always have enough stock for patients. If you have any questions, you can message our Patient Care team or doctors through your account.
