Our current lifestyle has numerous implications for our health. We know that working long hours sitting down causes back problems for a large part of the population, to give just one example. We must also consider that the way food is grown, transported, and stored can lead to certain nutritional deficiencies, to give another example. Spending many hours indoors can result in certain nutritional deficiencies, such as vitamin D deficiency. Vitamin D is obtained primarily through our skin, by exposure to sunlight. Several studies indicate that at least 40% of our body surface must be exposed to sunlight for effective absorption of UVB rays, which are the ones that promote vitamin D formation. Furthermore, this sun exposure should occur during the midday hours for better absorption, but this increases the risk of sunburn. Due to these and other circumstances, we find that vitamin D deficiency has reached epidemic levels, with 88% of the world's population suffering from vitamin D deficiency according to the British Journal of Nutrition. 
How to get vitamin D? There are three main sources of vitamin D: sun exposure, diet, and nutritional supplements. 80-90% of this vitamin is produced through sun exposure, while only 10-20% comes from food. And sun exposure, even if we were able to expose a sufficient surface area of our body for the recommended time, has other consequences, as it causes high levels of oxidation and increases the risk of skin cancer. To address this deficiency and ensure adequate vitamin D levels, nutritional supplements can be the most effective source. Vitamin D Nutritional Supplements. Together with Dr. Ángel Durantez, we have developed and manufactured a vitamin D3 supplement at 4000 IU (international units). This amount guarantees the necessary intake to achieve adequate vitamin D levels, as Dr. Ángel Durantez has clinically observed in his patients. Vitamin D3 
Vitamin D is currently the vitamin generating the most research and studies. This is because even in countries with many hours of sunshine per year, a very high percentage of the population has low levels. In Spain, this percentage is between 40 and 60% of the population. Vitamin D contributes to the maintenance of normal bones and normal muscle function. It helps with the absorption of calcium and phosphorus, maintains normal blood calcium levels, and preserves good dental health. It is also necessary and essential for strong bones and healthy teeth. Furthermore, it contributes positively to strengthening the immune system. Want more information about Longevitas Vitamin D? Click here

Take vitamin D. A little sun may not be enough.
Modern lifestyles, increased time spent indoors, and dietary habits have led to a vitamin D deficiency epidemic, affecting up to 88% of the world's population. Vitamin D is primarily obtained from sunlight (80-90%) and to a lesser extent from diet (10-20%). Due to risks associated with sun exposure, supplements have become the most effective source. Vitamin D3 contributes to the maintenance of healthy bones and teeth, muscle function, and a strengthened immune system. Longevitas offers a clinically proven 4000 IU supplement that ensures adequate vitamin D levels.
