Vitamin D Oral Sprays

The sunshine vitamin

Vitamin D is one of many fat-soluble vitamins that the body requires to function correctly. We make this essential vitamin from the skin's unprotected exposure to sunlight, but it can also be found in certain foods such as eggs, cereal, and fatty fish. Despite being vital for healthy bones and a robust immune system, our more sedentary lifestyles have meant that exposure to the sun has dropped dramatically, and our processed and specialist diets have meant that supplementation is needed to maintain a healthy level of vitamin D. For those looking for a reliable solution, our fast acting vitamin D supplements offer an effective way to supplement this essential nutrient.

Frequently Asked Questions

No. Our oral sprays bypass the primary processing of the digestive system, meaning they can be taken at any time of day, with or without food. The active ingredients are delivered directly into the bloodstream via the inner cheek.

Our oral sprays can be used under or on the tongue, but the most effective area is the inside of the cheek due to its rich vein system. This is also where we carry out our absorption testing.

The vitamin D3 contained in the majority of our vitamin D oral sprays is sourced from lanolin, which is derived from sheep wool.

However, the D3 in our Vegan Health Oral Spray is sourced from algae and is vegan-approved by the Vegetarian Society.

We recommend a maintenance dosage based on body weight and advise supplementation of 1000 IU of vitamin D per 25kg of body weight.

For most adults in the UK, this usually equates to 3000 IU of vitamin D per day.
