Burgerstein Vitamin D3 is a dietary supplement designed to compensate for insufficient natural production of vitamin D3 in the skin. This can occur due to inadequate sun exposure, often resulting from lifestyle habits, and is not uncommon during the winter months. Vitamin D3 contributes to the absorption and utilization of calcium as well as the maintenance of healthy bone mass. It is also essential for muscle function and the immune system, which require this vitamin in adequate amounts. Burgerstein D3 contains vitamin D3 in the highly bioavailable form of cholecalciferol. The neutral-tasting and pleasantly small capsules are particularly suitable for older adults, children, and anyone who does not get enough sun exposure. Free from lactose, yeast, peanut oil, soy lecithin, and gluten.
