Frequently Asked Questions

  • Expert Customer Service

Signs of low Vitamin D levels can include weak muscles, bones, and an impaired immune system. It can be hard to get enough Vitamin D from diet and sunlight alone, so Vitamin D deficiency can be very common. If you think you might be deficient in Vitamin D, speak to your GP, or consider one of our Vitamin D test kits.

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.

Yes, all of our packaging is fully recyclable. Please see our Better Planet Project page for more information.

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.
