Newborn Vitamin D Levels May Predict Future Mental Health Issues
Babies born with low levels of vitamin D might be more likely to develop mental health issues like ADHD, autism, and schizophrenia when they grow up.
This is based on a large study that looked at many people.
Vitamin D is important for brain development, and low levels are common in pregnant women.
Experts suggest that taking vitamin D supplements during pregnancy and early life could help.
You can get vitamin D from sunlight, food like fish and eggs, or supplements.
However, low vitamin D isn't the only thing that matters; other things like genes and stress also play a role.
Also, getting enough vitamin D can be a challenge in some places due to cost or access to food and supplements.
A study links low vitamin D levels in newborns to a higher risk of mental health disorders like schizophrenia, ADHD, and autism.
The research is based on a large population study assessing over 71,000 individuals.
Vitamin D is crucial for brain development, including regulating neurotrophic factors and influencing dopamine/serotonin systems.
Experts recommend vitamin D supplementation during pregnancy and early life to potentially reduce the risk.
Factors like genetics, maternal stress, and access to resources also influence mental health risk.
