There is a lot of talk about the effects of vitamin D3, and there are sound reasons for this, as its deficiency may be present in up to 1 billion people worldwide, and adequate concentrations are key to maintaining health [1]. In order to support the immunity we think about intensively during the autumn-winter season, we should provide this 'sunshine vitamin' in the right amount. However, its functions go significantly beyond immune care, so it is worth learning more about how important vitamin D3 is for humans of all ages.

Vitamin D is involved in the regulation of calcium and phosphate metabolism. It helps us maintain healthy bones and teeth and is important in maintaining normal blood calcium levels [2,3]. Vitamin D plays an important role in the body's immune function by influencing the innate and acquired immune response, which like a shield protects us from the external environment and pathogens [4]. The formation of new cells in the body, the production of insulin and the function of many genes are also dependent on the presence of vitamin D in our bodies [5]. The vitamin influences the proper development and function of skeletal muscles and is involved in optimising their strength, which is important for maintaining fitness in every individual [6].

Symptoms of vitamin D deficiency can include weakness in bones, joints, teeth, muscles, muscle tremors and even fatigue and impaired mood [7]. Dietary sources of vitamin D3 include fish, egg yolks, offal, and sunlight, which leads to the production of vitamin D in the skin [8]. Obtaining a sufficient intake of vitamin D from the diet is virtually impossible, and dermal synthesis via the sun may be suboptimal. Recent recommendations suggest supplementing vitamin D even throughout the year while ensuring hydration and adequate calcium intake from the diet [1]. How much we should supplement depends, among other things, on age, gender, physiological status, health status, and the current concentration of the 25(OH)D parameter in the blood.

Our supplement contains Quali®-D a stable and bioavailable form of vitamin D3 (naturally derived from lanolin), dissolved in MCT oil extracted only from the oil produced from the Cocos nucifera palm fruit. One capsule provides a daily dose of vitamin D3 (cholecalciferol) of 2000 IU = 50 μg (1000%). The product is in the form of easy-to-swallow soft capsules and is free of palm oil, sugar, gluten, lactose, soy and GMOs. Take care of your immunity, healthy bones, teeth and good health with our vitamin D3!
