Is maca a placebo effect?

It is important to consider the placebo effect with respect to maca. In particular, it is necessary to distinguish between actual physiological effects and placebo effects (the phenomenon of feeling an effect simply because you believe in it ) when evaluating effects on supplements.

What is the Placebo Effect?

The placebo effect refers to the phenomenon of improvement that occurs even when a “placebo” is used that does not contain an active ingredient. This effect often occurs because of the patient’s expectation that he or she is being treated.

Research on Maca

• Many studies evaluating the effects of maca compare it to a placebo group. This attempts to distinguish between the effects of maca itself and the placebo effect.
• Some studies have reported that taking maca is more effective than placebo in increasing libido and improving some sexual functions, but the size and quality of these studies varies.

Points to consider

• Placebo effects can be particularly strong in studies related to improved sexual function and wellbeing. People’s expectation of a positive psychological impact may itself actually make them feel an improvement in their symptoms.
• It is quite possible that expectations about the effects of maca may be a factor in causing a placebo effect. In other words, it can be difficult to distinguish whether maca is actually causing physiological changes or whether its use is providing psychological reassurance or anticipation.

Conclusion

Research findings on maca are mixed, and placebo effects have not been completely ruled out. Therefore, when using maca, it is recommended that you consider the totality of the scientific evidence and your own experience and, if necessary, consult with a health care professional.
