Does your milk supply drop during your period?

Understanding Milk Supply and Menstruation
For breastfeeding mothers, the return of menstruation can bring about various changes, including potential fluctuations in milk supply. Many women report experiencing a drop in breast milk production during their periods, a phenomenon that can be attributed to hormonal changes and shifts in calcium levels in the body.
Hormonal Influences
When menstruation begins, the body undergoes significant hormonal changes. Specifically, levels of estrogen and progesterone fluctuate, which can impact milk production. Higher estrogen levels, particularly, have been shown to interfere with the milk supply. This hormonal shift can lead to a temporary decrease in milk production, which many mothers notice around the time their period starts.
Calcium Levels and Milk Supply
Another critical factor in this equation is calcium. Research indicates that blood calcium levels tend to drop during menstruation, particularly around ovulation. This decrease in calcium may contribute to the reduction in milk supply that some mothers experience. To counteract this, lactation professionals often recommend calcium and magnesium supplements, as these can help stabilize blood calcium levels and potentially mitigate the drop in milk supply .
Individual Variability
It’s important to note that not all breastfeeding mothers will experience a significant drop in milk supply during their periods. The timing and intensity of menstruation can vary widely among individuals. Some mothers may not see their periods return until they begin weaning their babies off breast milk, while others might have their periods shortly after childbirth. This variability means that each mother’s experience can be quite different.
Coping Strategies
For those who do notice a decrease in milk supply during their menstrual cycle, there are several strategies that can help. Staying well-hydrated, getting adequate rest, and practicing relaxation techniques such as meditation or gentle exercise can be beneficial. Additionally, incorporating calcium and magnesium supplements into the diet may help maintain milk production levels during this time.
In conclusion, while many breastfeeding mothers may experience a drop in milk supply during their periods due to hormonal changes and fluctuations in calcium levels, individual experiences can vary. Understanding these factors can help mothers navigate their breastfeeding journey more effectively, ensuring both their health and that of their babies.

How to prevent milk supply drop during period?

Typically, the drop in milk supply is caused by the dropping of blood calcium levels during your cycle. To combat this, a calcium/magnesium supplement (not calcium alone) is recommended. The typical dosage is either 500mg/250mg or 1500mg/750mg (calcium/magnesium, respectively).

What causes a drastic drop in milk supply?
