The Breastfeeding Effect: What Happens to Your Period?

 

Your journey through motherhood is unique, and understanding how your body’s natural processes can influence breastfeeding is crucial. Here’s some essential information about how changes in your body’s mineral levels during your menstrual cycle can affect breast milk supply, and the role of iron in your overall well-being. 

Calcium and Your Menstrual Cycle 

During ovulation, leading up to the first few days of your menstrual period, your blood calcium levels gradually decrease. This decrease can impact your milk supply. If you notice a dip in breast milk production correlating with your menstrual cycle, a Calcium/Magnesium supplement might be beneficial. Not only can this supplement aid in stabilizing milk supply, but it’s also been noted to alleviate uterine cramps and premenstrual symptoms such as water retention. 

Note, any supplemental Calcium/Magnesium should be taken in a ration of 2:1 Calcium to Magnesium. 

  • Calcium: Between 500mg and 1500mg 
  • Magnesium: Between 250mg and 750mg 

These should be taken as a combined supplement, not individually, to enhance effectiveness and safety. The exact dosage depends on your diet; higher animal protein intake requires more calcium/magnesium, whereas a vegan/vegetarian diet may only necessitate the lower dose. If your daily calcium needs exceed 500mg, it’s best to split the dosage to enhance absorption, as the body absorbs calcium more efficiently in doses of 500mg or less. 

We often get asked to recommend products.  Our clients have found the following products to be effective: 

When to Take Your Supplement 

Begin supplementation at ovulation and continue through the early days of your menstrual period. For irregular periods, start 14 days after your last cycle begins or consider daily supplementation. 

Iron, Menstruation, and Breastfeeding 

Menstruation can lead to iron depletion in your body, affecting energy levels and potentially impacting milk supply. Maintaining a balanced iron level is essential for your health and the quality of breast milk. Include iron-rich foods in your diet, such as lean meats, beans, lentils, and fortified cereals, or consider an iron supplement if advised by your healthcare provider. 

If iron supplementation is required, we find clients do well with the following products: 

Monitoring and Adjustments 

Remember, everyone’s body reacts differently. Monitor your body’s response to supplementation and adjust as necessary under the guidance of a healthcare professional. Your well-being is paramount in providing the best care for your baby.
