1) What is Vitamin D3?
Vitamin D3 is one of the two major types of vitamin D called Cholecalciferol. Both forms of vitamin D are used as active compounds in dietary supplements all over the world, but it has been observed that vitamin D3 has a better absorption rate and is approximately three times more effective than vitamin D2. However, more recent research seems to reject this theory, but results are not yet conclusive.
The sources of vitamin D3 are sunlight and food. Food sources are however rather limited and include different types of fish, fish, fish oils, eggs. Many foods have been fortified with vitamin D to ensure that people consume enough of this nutrient (milk, cereals). Sunlight has also become an unreliable source in the past 20 years due to the continuous warnings issued by medical specialists all over the world regarding the harmful effects of UV radiation. The use of sun cream decreases considerably the absorption of vitamin D, and, as a result, a deficiency in this nutrient has become a lot more common. Supplementation is considered one of the best alternatives for preventing a deficiency in this vitamin.
Vitamin D plays numerous roles in the human body. Perhaps its most important is that of facilitating Calcium absorption, an essential mineral that forms our bone system. Without enough vitamin D in the body, the body cannot assimilate effectively Calcium, which results eventually in a Calcium deficiency. Such an imbalance results in severe bone affections such as rickets in children (abnormal growth of bones) or osteoporosis in adults (weak bones predisposed to fractures) .
Scientific research also revealed that deficiencies of vitamin D may be a cause for heart affections, diabetes, muscle weakness, arthritis, or cancers.

However, the numerous warning against the dangers of inappropriate sun exposure issued in recent years determined people to use sunscreen when exposed to direct sunlight.
