Vitamin D, also known as the sunshine vitamin, is important as it supports the body in regulating our intake of calcium and phosphorous, needed for the formation of healthy bones, teeth and muscles.

The latest addition to our award-winning vitamin D oral spray range is a maximum strength 4000 IU vitamin D3 oral spray, designed to elevate and maintain vitamin D levels in the body..
Formulated to provide optimal nutritional delivery, each spray provides the vitamin D in micro-sized droplets that coat and permeate the soft-tissue of the inner cheek, delivery the essential nutrients into the rich vein system below.
This allows the formulation to quickly enter the bloodstream for optimal absorption.
