Safe Use Guidelines
- Start low and increase slowly: Begin with 1/2 to 1 teaspoon of powder or the lowest recommended capsule dose, and gradually increase over a week or two.
- Monitor for symptoms: Track any changes in mood, energy, digestion, or menstrual cycle. Adjust dose or stop if adverse effects appear.
- Choose quality products: Prefer gelatinized (pre-cooked) maca for improved digestion. Ensure supplements are sourced from reputable brands and grown in Peru.
Signs to Reduce or Stop Use
- Unusual fatigue, rapid heart rate, jitteriness, sleep disturbances, or allergic symptoms (hives, swelling).
- Noticeable changes in menstrual cycles or hormone-related symptoms (without medical supervision).
