Why does B6 help with morning sickness?

Answered by Tom Adger

B6, also known as pyridoxine, is a vital nutrient that plays a crucial role in our body’s metabolism. One of its important functions is helping our bodies process certain amino acids, which are the building blocks of proteins. This ability to aid in protein metabolism may somehow contribute to the alleviation of morning sickness symptoms.

Several studies have explored the relationship between vitamin B6 levels and morning sickness severity, particularly in pregnant women. It has been observed that women experiencing severe morning sickness tend to have lower levels of vitamin B6 in their blood. This finding suggests that there may be a connection between B6 deficiency and the occurrence or intensity of nausea and vomiting during pregnancy.

The exact mechanism by which B6 helps with morning sickness is not fully understood. However, there are a few plausible explanations based on its role in the body. One possibility is that B6 influences the production of neurotransmitters such as serotonin and dopamine, which are involved in regulating mood and nausea. By increasing B6 levels, the production and function of these neurotransmitters may be enhanced, potentially reducing feelings of nausea.

Additionally, B6 is involved in the synthesis of certain enzymes that help break down and process various substances in the body. This includes the metabolism of certain hormones, such as estrogen and progesterone, which undergo significant changes during pregnancy. By ensuring optimal B6 levels, the body may be better equipped to handle these hormonal fluctuations, potentially reducing the incidence of morning sickness.

It’s important to note that the effectiveness of B6 in relieving morning sickness can vary from person to person. While some women may experience significant relief, others may not notice a significant difference. It is always recommended to consult with a healthcare professional before starting any supplementation, especially during pregnancy, to ensure appropriate dosage and safety.

While the exact mechanisms are not fully understood, studies have shown a correlation between lower vitamin B6 levels and more severe morning sickness symptoms. B6’s role in protein metabolism and its potential influence on neurotransmitter production and hormonal balance may contribute to its ability to alleviate nausea. However, individual responses may vary, and it is essential to seek medical advice before starting any supplementation.
