Before you start taking a course of black radish juice or rushing to the chemist's to buy supplements, it's best to be aware of the side effects that can occur.

But that doesn't mean it's totally free of side effects. Here's what can happen when your intake is too high or ill-adapted to your profile.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Des_troubles_digestifs_ca_arrive\"><\/span>Digestive problems happen!<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Black radish contains <strong>glucosinolates<\/strong> and sulfur compounds (such as raffanine) that can irritate the gastric mucosa. As a result, some people experience bloating, gas, abdominal pain or heartburn.<\/p>\n<p>If you have a sensitive stomach, gastritis or peptic ulcer, this is a warning signal not to be ignored. Raw black radish juice is often more aggressive than standardized tablets or capsules. Start slowly, especially if this is your first treatment!<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Une_action_trop_%C2%AB_boostee_%C2%BB_sur_la_bile\"><\/span>An overly \u00abboosted\u00bb bile action<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Black radish is a <strong>cholagogue<\/strong> and a <strong>choleretic<\/strong> powerful: it increases bile production by the liver and stimulates its emptying into the intestine. This is great for fat digestion... but it can also cause abdominal cramps or diarrhoea if your digestive system is a little fragile.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Le_radis_noir_est-il_dangereux_pour_la_thyroide\"><\/span>Is black radish dangerous for the thyroid?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div style=\"position: relative; width: 100%; padding-bottom: 56.25%; margin: 30px 0; border-radius: 8px; overflow: hidden;\">\n<iframe style=\"position: absolute; top: 0; left: 0; width: 100%; height: 100%; border: none;\" src=\"https:\/\/www.youtube.com\/embed\/FztGvX_DtMk\" allowfullscreen><\/iframe>\n<\/div>\n<p>It's a question many people ask, and rightly so! The black radish belongs to the <em>Brassicaceae<\/em> (such as cabbage, broccoli and turnips). This family contains substances called <strong>goitrogens<\/strong>, which can interfere with iodine absorption by the thyroid gland.<\/p>\n<p>To put it plainly: in cases of proven hypothyroidism or levothyroxine-based treatment (Levothyrox\u00ae, for example), excessive consumption of black radish could disrupt the proper functioning of your thyroid gland. This is not always the case, but it's best to talk to your doctor before starting a course of treatment.<\/p>\n<p>People affected by <strong>hypothyroidism<\/strong> represent around 3 to 5 % of the French population - so it's far from anecdotal!<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Quelles_sont_les_contre-indications_majeures_du_radis_noir\"><\/span>What are the major contraindications to black radish?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Now we're getting serious. Certain profiles should avoid black radish altogether, or at least never take it without prior medical advice.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Obstruction_biliaire_et_calculs_biliaires\"><\/span>Biliary obstruction and gallstones<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>This is the number-one contraindication. If you suffer from <strong>biliary tract obstruction<\/strong> or biliary lithiasis (stones in the gallbladder), black radish is strictly inadvisable. By suddenly stimulating gallbladder contraction, it can trigger a hepatic colic attack or aggravate acute cholecystitis. Not at all what we're looking for!<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Radis_noir_et_grossesse_prudence_de_mise\"><\/span>Black radish and pregnancy: caution is advised<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>During the <strong>pregnancy<\/strong> and breast-feeding, the use of black radish as a concentrated dietary supplement is not recommended by health professionals. Available data are insufficient to guarantee total harmlessness for the fetus or infant. Cooked black radish (in salads or cooked) is quite different from an intensive course of treatment in juice or capsules.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Enfants_et_personnes_agees\"><\/span>Children and the elderly<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Black radish-based supplements are generally not suitable for children under 12. For frail elderly people or those undergoing multiple treatments, a medical consultation is required before any treatment.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Ulceres_et_pathologies_gastro-intestinales\"><\/span>Ulcers and gastrointestinal pathologies<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In cases of gastric or duodenal ulcer, severe gastroesophageal reflux disease (GERD) or Crohn's disease, black radish's irritating compounds can aggravate inflammation.

Just follow a few simple rules!<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Respecte_la_posologie_recommandee\"><\/span>Adheres to recommended dosage<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Whether you consume fresh black radish juice or capsule supplements, don't exceed the indicated doses. In phytotherapy, standardized extracts of black radish are generally dosed between <strong>300 and 500 mg per day<\/strong>.
