Deficiency of Vitamin D is highly prevalent amongst the UK population, and the NHS recommends taking a supplement of at least 400iu per day. Vitamin D is obtained naturally from two sources: sunlight and food. It is, however, found in only a few foods and we get the majority of our intake from the action of sunlight on our skin. Our new, easy to use, one-a-day D3 booster formulation is sprayed directly onto the tongue, and has been designed to provide additional support for your intake of this vital micro-nutrient. We’ve completed this with Vitamin K2, which plays a vital role in the absorption of Vitamin D3, ensuring it gets absorbed in the right places in our body. One spray provides 1000IU of Vitamin D, 500% of the recommended intake to ensure you have optimum Vitamin D levels throughout the year. Plus the optimal amount of Vitamin K2.
