This is a superior product using an advanced and friendly formula that tastes great! Vitamin D is Essential for normal teeth and bones, muscle function, and important for a healthy immune system. Our body creates Vitamin D from direct sunlight and we also get some Vitamin D from a small number of foods, including oily fish, red meat and eggs. A lack of vitamin D can cause bones to become soft and weak, which can lead to deformities such as rickets in children, or osteomalacia in adults. Studies have also shown that Vitamin D deficiency can cause weight gain and result in excess belly fat. This convenient, orange flavour spray is formulated to deliver Vitamin D directly into the bloodstream. As we all know Vitamin D3 is dangerous to inject as it is fat soluble, and studies show that administering a spray under the tongue and allowing it to absorb for 15 seconds is just as effective as an injection. Vitamin D3 is vital in this climate and your will love it.
