Maca belongs to the mustard family and contains glucosinolates, which in large amounts combined with a low-iodine diet have been linked to goiter.<\/p>\n<p>People with a thyroid disorder are therefore advised to avoid it, or at minimum to consult a doctor before use. Anyone on thyroid medication should tell their doctor.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Maca_side_effects_in_pregnancy_and_breastfeeding\"><\/span>Maca side effects in pregnancy and breastfeeding<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Avoid maca during pregnancy and breastfeeding. The reason is not a proven harm but <strong>insufficient safety data<\/strong> in these stages \u2014 and absence of evidence is not evidence of safety.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Maca_side_effects_with_hormone-sensitive_conditions_and_medication\"><\/span>Maca side effects with hormone-sensitive conditions and medication<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Although maca does not raise blood hormone levels, anyone with a hormone-sensitive condition is advised to check with a doctor first as a precaution.<\/p>\n<p>As for drug interactions, references describe them as &#8220;none well documented&#8221; \u2014 meaning no confirmed interactions are known. That does not remove the need to tell your doctor everything you take, particularly alongside hormone therapy, thyroid medication and fertility treatment.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Are_weight_gain_and_high_blood_pressure_maca_side_effects\"><\/span>Are weight gain and high blood pressure maca side effects?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Maca is low in calories and contains nothing that directly adds weight; reported gain usually tracks improved appetite and added muscle mass alongside activity.<\/p>\n<p>No data link it to raised blood pressure. Even so, anyone with uncontrolled hypertension should prioritise controlling that rather than adding a supplement.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_safe_dose_that_avoids_maca_side_effects\"><\/span>The safe dose that avoids maca side effects<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Study doses ranged from 1.5 to 3.5 grams daily depending on the goal, used for periods of up to four months without recorded problems.<\/p>\n<p>Stick to the dose on the label and do not exceed it on the assumption that more is faster \u2014 in one study no difference appeared between 1.5 and 3 grams.

Maca is a herbal dietary supplement, not a medicine, and everything here is for general awareness only. It is not a substitute for advice from a qualified doctor or pharmacist. Individual results vary, and no supplement should be relied on to diagnose or treat a medical condition.<\/p>\n<p style=\"font-size:0.95em;color:#555;\">Avoid maca during pregnancy and breastfeeding, as safety data are insufficient. People with thyroid disorders are advised to avoid it, because glucosinolates in large amounts combined with a low-iodine diet have been linked to goiter.
