Maca root, often called Peruvian ginseng, is a popular dietary supplement known for its traditional use in supporting energy and vitality. As its popularity has grown, many people who are expecting have questions about its safety. This information provides clarity on the use of maca root during pregnancy, based on current scientific and medical understanding.
Current Consensus on Use During Pregnancy
The use of maca root during pregnancy is met with caution. As a dietary supplement, it does not undergo the rigorous testing required for pharmaceutical drugs by regulatory bodies like the U.S. Food and Drug Administration (FDA). Standard medical advice leans toward avoidance due to this lack of firm data.
The primary reason for this caution is the absence of human clinical trials investigating its safety in pregnant individuals. Ethical limitations prevent researchers from conducting controlled trials on herbal supplements with unknown effects on fetal development. Without this evidence, healthcare providers cannot confirm that the supplement is safe for the developing fetus.
Medical professionals advise pregnant women to approach the use of maca root with caution. Before consuming maca root or any other herbal supplement, consultation with an obstetrician-gynecologist or a midwife is recommended.
What Is Maca Root and Its Traditional Use?
Maca root (Lepidium meyenii) is a member of the cruciferous vegetable family, which includes broccoli and cabbage. It is native to the high-altitude Andes mountains of Peru, where it has been cultivated for at least 3,000 years. The plant grows in harsh conditions, making it one of the highest-elevation crops in the world.
Traditionally, the fleshy underground storage organ, or hypocotyl, was consumed as a food source, much like a potato. Indigenous cultures historically used it to promote endurance, boost energy, and support fertility. The root is typically dried and ground into a powder, which is consumed in capsules, extracts, or added to foods.
Maca comes in different varieties, commonly yellow, red, and black, with yellow being the most common. While traditional uses include enhancing sexual desire and physical stamina, these applications are not fully supported by modern research due to a lack of rigorous scientific evidence.
Understanding Maca’s Hormonal Influence
The mechanism of action that generates the most concern during pregnancy relates to maca root’s influence on the endocrine system. Maca is often classified as an adaptogen, meaning it helps the body respond to and manage stress. This adaptogenic property is thought to work by indirectly modulating the body’s complex hormonal pathways.
Maca root itself does not contain hormones, but its active compounds, which include alkaloids, macamides, and glucosinolates, may influence hormone-regulating glands. These compounds are thought to interact with the Hypothalamic-Pituitary-Adrenal (HPA) axis, the central regulator of the stress response and many endocrine functions. By influencing this axis, maca could potentially affect the production of ovarian hormones like estrogen and progesterone.
During pregnancy, the balance of these hormones is tightly controlled and absolutely necessary for the maintenance of the pregnancy and the proper development of the fetus. Introducing a substance known to influence this delicate hormonal equilibrium, even indirectly, is considered a potential risk. There is simply no data on how maca’s bioactive components interact with the placenta or what effect they might have on the developing fetal endocrine system. This unknown interaction is the primary reason for medical caution, especially since some extracts are thought to mimic estrogen-like activity.
Maca Root and the Postpartum Period
After pregnancy, the focus shifts to using maca root to support postpartum recovery and lactation. Postpartum recovery involves major hormonal shifts, mood adjustments, and intense fatigue, where maca’s traditional use for energy and mood balance might seem appealing. Historically, maca consumption was common in Peru both during and after pregnancy, with traditional beliefs suggesting it aids in stress resilience.
When considering the nursing period, caution is introduced regarding the transfer of components through breast milk. The bioactive compounds in maca root, such as macamides and glucosinolates, have not been adequately studied to determine if they pass into breast milk or what their effect might be on a nursing infant. The lack of clinical safety data remains a concern for many medical bodies.
Given this uncertainty, a healthcare provider, such as a pediatrician or lactation consultant, should be consulted before resuming maca root use while nursing. If a mother chooses to incorporate maca for energy or mood support, ensuring the product is gelatinized or activated is recommended. Raw maca can be inflammatory and may contain contaminants like heavy metals, which are especially dangerous during this period.
