They have taken this information, and suggested that the same benefits can be expected in humans.
Whilst it is true that, as animals, and mammals, humans do have many similarities to mice, it is well beyond the scope of the published article to conclude that Vitamin B3 supplements could benefit humans.
Vitamin B3 is a common component of a healthy diet, which includes fresh vegetables, cereals, and Vegemite! As many people’s diet can be at times, unhealthy, there may be some who are deficient in vitamin B3.
When planning a pregnancy, it is recommended to take a pregnancy multi vitamin, as it has been proven, in humans, that particular vitamins, such as folate, reduce the risk of abnormalities. The other vitamins in theses preparations MAY further reduce the risks.
There is no vitamin, unfortunately, that has been proven to reduce the overall risk of miscarriage.
Whilst this latest report is interesting, we should wait until studies in large numbers of humans have been performed to see whether Vitamin B3 supplements are of benefit to women planning pregnancy.
In the meantime, if you are planning to have a baby, keep active, eat a healthy diet, and take a multivitamin supplement!
All the best
