Population studies show that between 10-20 per cent of all adults in the developed world suffer from vitamin C deficiency. Therefore, pregnant women should think twice about omitting the daily vitamin pill.
“Even marginal vitamin C deficiency in the mother stunts the foetal hippocampus, the important memory centre, by 10-15 per cent, preventing the brain from optimal development,” says Professor Jens Lykkesfeldt. He heads the group of scientists that reached this conclusion by studying pregnant guinea pigs and their pups. Just like humans, guinea pigs cannot produce vitamin C themselves, which is why they were chosen as the model.
“We used to think that the mother could protect the baby. Ordinarily there is a selective transport from mother to foetus of the substances the baby needs during pregnancy. However, it now appears that the transport is not sufficient in the case of vitamin C deficiency. Therefore it is extremely important to draw attention to this problem, which potentially can have serious consequences for the children affected,” says Jens Lykkesfeldt.
Too late when damage is done
The new results sharpen the focus on the mother’s lifestyle and nutritional status during pregnancy. The new study has also shown that the damage done to the foetal brain cannot be repaired, even if the baby is given vitamin C after birth.
When the vitamin C deficient guinea pig pups were born, scientists divided them into two groups and gave one group vitamin C supplements. However, when the pups were two months old, which corresponds to teenage in humans, there was still no improvement in the group that had been given supplements.
The scientists are now working to find out how early in the pregnancy vitamin C deficiency influences the development of foetal guinea pigs. Preliminary results show that the impact is already made early in the pregnancy, as the foetuses were examined in the second and third trimesters. Scientists hope in the long term to be able to use population studies to illuminate the problem in humans.
There are some groups that may be particularly vulnerable of vitamin C deficiency:
“People with low economic status who eat poorly - and perhaps also smoke - often suffer from vitamin C deficiency. Comparatively speaking, their children risk being born with a poorly developed memory potential. These children may encounter learning problems, and seen in a societal context, history repeats itself because these children find it more difficult to escape the environment into which they are born,” says Jens Lykkesfeldt.
He emphasises that if pregnant women eat a varied diet, do not smoke, and for instance take a multi-vitamin tablet daily during pregnancy, there is no reason to fear vitamin C deficiency.
“Because it takes so little to avoid vitamin C deficiency, it is my hope that both politicians and the authorities will become aware that this can be a potential problem,” concludes Jens Lykkesfeldt.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
