What is vitamin D3?

Vitamin D, also known as calciferol, is a vitamin that is soluble in fat and plays an important role in the absorption of calcium from our food, maintains a sufficient level of calcium in our blood and thereby supports strong bones. Vitamin D is also important for maintaining strong and flexible muscles, strong teeth and a healthy immune system. Vitamin D plays an important role in many vital functions of our body and it is thus very important to have sufficient blood levels of this vitamin.

Sources of vitamin D3

Vitamin D is a special vitamin since there are relatively few food products that contain Vitamin D such as fatty fish, liver, meat, eggs and dairy and then usually only in limited quantities. More abundant sources of vitamin D are certain fatty fish like eel, mackerel and salmon. Many people have insufficient blood levels of vitamin D, especially during the winter months. For this reason, vitamin D has been added to products like margarine and baking oils. The most abundant source of vitamin D is our skin where vitamin D3 is produced every time it comes into contact with ultraviolet sunlight (UV-B). The particular form vitamin D is also referred to as cholecalciferol that can also be stored in the liver as calcidiol for possible later use, especially during the winter months when sunlight is scarce.

Vitamin D3 and our bones

Vitamin D3 enhances the absorption of calcium from our food as well as the absorption of calcium from the blood into our bones. Since strong bones are a prerequisite for good health, especially when we age, it is important to have sufficient blood levels of vitamin D. For this reason, we have added Vitamin D3 to Synofit Premium Capsules and Synofit Premium Liquid. Synofit Premium also contains the Green-lipped mussel, Curcumin and Blackcurrant leaves and helps to maintain and improve our bone, joints and muscles.

Vitamin D3 and our muscles

Regular exercise is important to keep your bones, muscles and joints in a perfect condition. Especially when you age we advise that you either walk, swim or bicycle daily for about half an hour. In addition to exercise, sufficient blood levels of vitamin D3 will help to keep your muscles flexible.

Vitamin D3 and our blood

Vitamin D3 is necessary to maintain normal levels of calcium in our blood which is not just essential for maintaining healthy bones but also for a healthy heart muscle.
