The daily oral spray has been scientifically formulated to deliver vitamin D3 directly into the bloodstream, bypassing the primary processing by the gut. The tiny droplets within the spray absorb quickly into the buccal membrane of the inner cheek, providing fast and eff ective nutrient uptake. Our work with Cardiff University has produced a nutritional delivery system that provides an eff ective and convenient alternative to tablets and capsules. Vitamin D helps in the maintenance of bones and teeth, supports a normal, healthy immune system and contributes to the normal muscle function.
