Mental Side Effects

Some side effects associated with maca root powder use involve the central nervous system and brain activity. According to, side effects associated with maca root supplements focusing specifically on the central nervous system and brain include mood swings, headaches and insomnia. Research into the prevalence of these side effects and their consistency among all patients needs to be conducted in order to substantiate these claims; however the website does suggest that you should first check with a medical professional before consuming maca root powder if you have a history of headaches or insomnia.

Thyroid Complications

If you are currently receiving treatment for a thyroid-related medical condition, then you may want to reconsider taking maca root powder for the treatment of another health ailment. According to, one major side effect associated with maca root is an unhealthy increase in iodine levels in patients suffering from a thyroid disorder. As the website suggests, maca root supplements contain a high level of natural iodine, which could lead to complications for patients already afflicted with abnormally high iodine blood levels. When in a high concentration within the body, iodine excess can lead to further medical complications including but not limited to kidney failure and other insulin-related illnesses. As the website suggests, extreme cases of iodine-related disorders include the development of goiter, or an enlarged thyroid gland.

Other Side Effects

The website also lists additional symptoms as side effects associated with maca root powder supplements. These possible side effects include high blood pressure, indigestion, heart burn, hot flashes and an increased heart rate. While side effects can differ from patient to patient, it is in your best interest to contact your medical doctor immediately if you experience any negative effects following maca root powder use or consumption.
