Safety, Side Effects and Contraindications

Lepidium meyenii, also known as maca, is generally considered safe for short-term use in most healthy adults when taken in recommended doses, though it may cause mild side effects such as gastrointestinal discomfort, insomnia, or increased heart rate in some individuals.

It may interact with medications such as antidepressants, blood pressure drugs, or hormonal therapies, potentially altering their effectiveness or increasing side effects. Special populations, including pregnant or breastfeeding women, should avoid maca due to insufficient safety data, and individuals with chronic illnesses like hypertension or thyroid disorders should consult a healthcare provider before use. To ensure safe use, it is advisable to start with a low dose, choose a high-quality supplement from a reputable source, and discontinue use if adverse reactions occur.

Always consult with a healthcare professional before incorporating maca into your regimen, especially if you have existing health conditions or are taking other medications.

Growing, Harvesting and Storage

Lepidium meyenii grows in high-altitude regions, typically between 3,000 and 4,000 meters above sea level, where it thrives in well-drained, loamy soils with a pH of 6.0 to 7.5.

It requires full sun exposure and moderate water, with careful irrigation to avoid waterlogging, which can lead to root rot. Regular weeding and monitoring for pests such as aphids and nematodes are essential for maintaining healthy growth. The plant is harvested during the dry season, usually between October and December, by carefully uprooting the entire plant to preserve the root, which contains the active compound macaene.

To preserve its potency, the harvested roots are washed, dried in the shade, and stored in airtight containers in a cool, dark, and dry place, or refrigerated to extend shelf life and maintain nutritional value.
