New Study demonstrates the importance of Vitamin D in pregnancy.

New research findings by London’s suggest that pregnant women pass low levels of on to their babies at almost three times the extent previously thought.

A new measuring technique developed to examine the level of eight different forms of in greater detail has determined that 56 per cent of comes directly from the mother. A  much higher figure than the previously estimated 19%.

The study, just published in , focused on 120 samples taken from 60 Greek mothers and their babies. The research was conducted with the Department of at Aristotle University of Thessaloniki in Greece. The research revealed that many of the mothers had low levels of , suggesting that what they ate was an equally important source.

Professor , who headed the research team, said the findings made it more important than ever that mothers-to-be received the key nutrient not only through sunlight but also through foods such as oily fish. “The impact that mothers deficient in have on their babies’ levels is a much bigger problem than we thought,” Professor said. “Maintaining good supplies during pregnancy is clearly of vital importance for both mothers’ and babies’ long term health.”

Lack of the vitamin in pregnant women has been linked to diabetes and increased rates of births, while babies can be smaller than average. In children, the deficiency can cause rickets — a disease.

plays an important role in maintaining good levels of calcium and phosphate which help form healthy bones and teeth. The two main forms are 3, which primarily comes from sunlight, and D2 which is found in a small number of foods including , mushrooms, farmed salmon, , and fortified bread and cereals. Processes in the body convert the vitamin into what is known as the circulating form — the type commonly measured in routine blood tests — followed by the active form — the type that promotes calcium absorption, cell growth and immunity.

Professor and his team found that the type of commonly measured in blood tests was not as reliable an indicator of activity as other strands. They went on to discover that two epimer forms, previously thought to be unimportant, influenced levels in babies. “This shows the need for more accurate measurement to assess levels of as well as the need to look more closely at its different forms,” Professor said.
