Capsules, however, provide a concentrated daily amount, which is why it helps to understand <strong>fenugreek side effects<\/strong> before you start. Here are 8 reactions and interactions to know, and when to stop and see a doctor.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"1_Digestive_Fenugreek_Side_Effects\"><\/span>1. Digestive Fenugreek Side Effects<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The most common complaints are diarrhoea, gas and bloating, and sometimes nausea. These are partly due to the fibre in the seeds. They are usually mild and often ease when you take the capsules with food or lower the dose.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"2_Maple_Syrup_Odour\"><\/span>2. Maple Syrup Odour<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Fenugreek can give urine and sweat a smell like maple syrup, and the same odour can appear in a breastfed baby. It is harmless, but tell your pediatrician, because it can be confused with a rare inherited condition called maple syrup urine disease.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"3_Allergic_Reactions\"><\/span>3. Allergic Reactions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Fenugreek is a legume, and cross-reactivity can occur in people allergic to peanuts or chickpeas. Symptoms include rash, itching and facial swelling, and rarely breathing difficulty. Stop at once and seek emergency care if your face swells or you become short of breath.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"4_Low_Blood_Sugar_With_Diabetes_Medicines\"><\/span>4. Low Blood Sugar With Diabetes Medicines<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Fenugreek may lower glucose slightly, adding to the effect of insulin and diabetes tablets and possibly causing hypoglycaemia. This is why the Nature&#8217;s Way label advises people with diabetes to monitor blood glucose closely. Details are in <a href=\"https:\/\/nostylelike.net\/en\/fenugreek-and-blood-sugar\/\">fenugreek and blood sugar<\/a>.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"5_Interaction_With_Blood_Thinners\"><\/span>5. Interaction With Blood Thinners<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Case reports suggest fenugreek may increase bleeding risk or change INR in people taking warfarin, and possibly with aspirin or clopidogrel. It is reasonable to stop fenugreek about two weeks before any planned surgery and to tell your doctor or dentist that you take it.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"6_Pregnancy_and_Trying_to_Conceive\"><\/span>6. Pregnancy and Trying to Conceive<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>One of the most important fenugreek side effects is possible uterine stimulation at high doses. The <a href=\"https:\/\/nostylelike.net\/en\/product\/solaray-fenugreek-1240-mg-180-vegcaps\/\">Solaray Fenugreek 1240 mg<\/a> label warns against use during pregnancy, and the <a href=\"https:\/\/nostylelike.net\/en\/product\/nature-s-way-fenugreek-seed-1130-mg-180-capsules\/\">Nature&#8217;s Way Fenugreek Seed 1130 mg<\/a> label warns against use if pregnant or trying to become pregnant.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"7_Thyroid_Hormones\"><\/span>7. Thyroid Hormones<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Animal studies and limited human reports suggest fenugreek may affect thyroid hormone levels. If you take thyroid medicine, speak to your doctor and keep up with your blood tests.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"8_Fenugreek_Side_Effects_When_Combined_With_Other_Medicines\"><\/span>8. Fenugreek Side Effects When Combined With Other Medicines<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The fibre in fenugreek may slow the absorption of some medicines taken at the same time. Leave about two hours between fenugreek and other medicines, and tell your pharmacist everything you take, including herbs and vitamins.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_to_Reduce_Fenugreek_Side_Effects\"><\/span>How to Reduce Fenugreek Side Effects<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<table style=\"width: 100%; border-collapse: collapse; margin: 12px 0;\">\n<tbody>\n<tr>\n<th style=\"border: 1px solid #ddd; padding: 8px; background: #f5f5f5;\">Product<\/th>\n<th style=\"border: 1px solid #ddd; padding: 8px; background: #f5f5f5;\">Amount per serving<\/th>\n<th style=\"border: 1px solid #ddd; padding: 8px; background: #f5f5f5;\">Label directions<\/th>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\"><a href=\"https:\/\/nostylelike.net\/en\/product\/solaray-fenugreek-1240-mg-180-vegcaps\/\">Solaray Fenugreek 1240 mg<\/a><\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">1,240 mg per 2 capsules<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">2 capsules twice daily with a meal or a glass of water<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\"><a href=\"https:\/\/nostylelike.net\/en\/product\/nature-s-way-fenugreek-seed-1130-mg-180-capsules\/\">Nature&#8217;s Way Fenugreek Seed 1130 mg<\/a><\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">1.13 g per 2 capsules<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">2 capsules two to three times daily<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<ul>\n<li>Do not exceed the dose on the label.<\/li>\n<li>Take capsules with food to limit stomach upset.<\/li>\n<li>Ask your doctor first if you use diabetes, blood-thinning or thyroid medicines.<\/li>\n<li>Stop if you develop an allergy or persistent diarrhoea.<\/li>\n<\/ul>\n<p>Nursing mothers considering fenugreek can read <a href=\"https:\/\/nostylelike.net\/en\/fenugreek-for-breastfeeding\/\">fenugreek for breastfeeding<\/a>, and new mothers looking for nutritional support can read about <a href=\"https:\/\/nostylelike.net\/en\/pregnacare-new-mum-benefits\/\">Pregnacare New Mum benefits<\/a>.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Who_Is_Most_at_Risk_of_Fenugreek_Side_Effects\"><\/span>Who Is Most at Risk of Fenugreek Side Effects?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Fenugreek side effects are more likely or more serious in certain groups, who should speak to a doctor before starting:<\/p>\n<ul>\n<li>Pregnant women and those trying to conceive.<\/li>\n<li>People with diabetes using insulin or glucose-lowering tablets.<\/li>\n<li>People taking warfarin or other blood thinners, or with a bleeding disorder.<\/li>\n<li>People allergic to peanuts, chickpeas or other legumes.<\/li>\n<li>People with thyroid disease or asthma.<\/li>\n<li>Children, since these products are labelled for adults.<\/li>\n<\/ul>\n<p>For a healthy adult who takes no medicines, fenugreek side effects are usually limited to mild digestive symptoms and the maple syrup odour.
