Maca Powder Benefits… Is Recommending Maca Good for Hormone Health or All Hype?

Is there any evidence that adding that scoop of Maca powder to your smoothie is a good idea?  Are maca powder benefits all that they’re hyped up to be?

As with nearly everything… the answer is, “It depends.”

In my practice, I recommend Maca for specific situations and it works very well.  But, in some situations, using maca can actually worsen your client’s symptoms.  Let’s tease out the data.

Do you have questions about adrenal, thyroid, or sex hormones? Do you want to strengthen your ability to use nutrition and lifestyle recommendations to support your clients to balance hormones and relieve their hot flashes, anxiety, vaginal dryness, hair loss, fatigue, belly fat, low libido, or other hormone imbalance symptoms?

Maca is best studied in perimenopausal and postmenopausal women for improving hot flashes and other symptoms of menopause (Comhaire & Depypere, 2015 and Depypere & Comhaire, 2014), a few randomized controlled trials have proven its effectiveness in these populations (Lee et al., 2011).  In a small, randomized, double-blind, placebo-controlled, cross-over study conducted on postmenopausal women in Hong Kong and China, reductions in blood pressure and depression were found, but there were no significant differences found in hormone levels or serum cytokines at doses of 3.3 grams per day (Stojanovska et al., 2015).  Reductions in anxiety and depression were found in another small study looking at postmenopausal women as well (Brooks et al., 2008).  Additionally, there is limited evidence (one randomized, double-blind, placebo-controlled, crossover trial on fourteen postmenopausal women), that Maca improves sexual function, but again, no effect on hormone levels was found (Brooks et al, 2008).

Clinically, I do recommend maca to my clients who are perimenopausal to postmenopausal and who need support with depression, anxiety, low libido, and reduction of menopausal symptoms.  However, I do not use it with women who are struggling with estrogen dominant issues (endometriosis, ovarian cysts, and fibroids) as it seems to exacerbate them.  However, this may be more of a belief or placebo effect, because I could find very little evidence that Maca is estrogenic.  It has not been found to bind to estrogen receptors (Powers & Setzer, 2015).  The above studies that did find improvements using Maca on psychological symptoms, libido, and menopausal symptoms, did not find changes in hormone levels.  However, there is one study on a specific, commercially available preparation of Maca (Maca-GO or Femmenessence) that did show significantly stimulated production of E2 (Meissner, et al., 2006.)

Because of the limited data available on Maca, I prefer to use it as a food based supplement, and add it to smoothies when my client feels that she needs support for her mood, libido, energy, or menopausal symptoms such as hot flashes.  The brands that I use regularly in my smoothies include Navitas Naturals which is only Maca, or Mighty Maca Plus, which is a supplement that was developed by my friend and colleague, Dr. Anna Cabeca after her travels around the globe to research tools for her own hormonal healing.  I prefer to use Mighty Maca Plus when I also feel the need for detoxification support as it contains sources of antioxidants and cruciferous vegetables in addition to Maca.  The recommended dose is between 2 grams and 3.3 grams per day.

Here is my recipe for a Mighty Maca Smoothie…
