AS NATUROPATHIC DOCTORS, an area that we excel in is balancing our patients hormones (male or female).

A common misconception that women have about their menstrual cycle is that the birth control pill (BCP) is prescribed to regulate their cycle. This couldn’t be further from the truth.

It is important that medical professionals start referring to the birth control pill for what it is:

A suppressive hormonal therapy that overrides the natural production of hormones.

Also, women need to be aware that there are side effects to taking the BCP that can be life-threatening. These side effects include:

  • Blood clots (which can lead to death1)
  • Breast cancer risk
  • Depression

Less serious side effects include:

  • Headaches
  • Dizziness
  • Nausea
  • Breast tenderness
  • Break through bleeding
  • Decreased libido

Also, the pill can deplete your nutritional status which ultimately exacerbates these side effects. The table2 below shows what nutrients are depleted by the BCP, the symptoms that occur due to nutrient deficiencies and food sources of the nutrient.

With some nutrients, such as the B vitamins, Magnesium and vitamin C, supplementation will be necessary to get the number of milligrams required to restore function while you are taking the BCP.

If you are using a copper IUD, it is especially important to supplement with zinc in order to offset the copper being absorbed. It is best to see an ND who can help you determine the appropriate doses for your individual needs.

Many nutrients become imbalanced when taking the BCP. What amazes me about this medication is that women often take it for several years, even decades, without questioning the long-term effects it could be having on their health.


I had a patient who was 49 years old, and had been taking the BCP for 20 years. She was experiencing hair loss and I suggested going off the pill. The interesting thing is after stopping the medication she never got another period!

And now, 6 years later, she remains in menopause with no negative symptoms and her hair loss has stopped. I wonder how many years she took the medication unnecessarily and if she had stopped it sooner what might have happened.

I know that the BCP can and does work for many women, however, if you are using it to put a band-aid over annoying menstrual symptoms, to clear up acne, to address a heavy menstrual flow or because you don’t know what else to do, you should know that there is another more effective option to balancing your hormones.

Naturopathic medical approach gets to the underlying causes of all of those symptoms, balancing your hormones and avoiding the dangerous side effects of medication. If you are on the birth control pill, but you aren’t sexually active, maybe now is a perfect time to take a break from unnecessary medications and allow the natural rhythm of your body to be restored.

Always remember, that once you are armed with the right information about how your body works, you can make healthy choices that work for you!  I know you can do this – the science of your hormones is on your side!
