Tea (dandelion)
Beverages · Coffee Tea
Dandelion tea is rated amber even at a weak brew: 0.18 g of fructans in a 250 ml cup, comfortably past the 0.1 g mark where a portion turns moderate. That makes it a poor default drink, and a default drink is exactly what it is sold as, marketed as a detox or liver tea and taken deliberately, several mugs a day.

Breakdown for 1 cup
Is tea (dandelion) low FODMAP?
The fructans come from the root. Dandelion root stores its carbohydrate as inulin, which is a fructan, in the way chicory root does, and hot water pulls it straight into the cup. Steeping time moves the number on any herbal tea, but dandelion begins high enough that even the weak version is amber, and that is where it parts company with the rest of the shelf. Chamomile records 0.05 g weakly brewed and fennel 0.08 g, both green at that strength. Only the weak brew has been measured here, and a stronger one can only go one way.
Tea (dandelion) and IBS: what to know
Two habits turn this from a footnote into something worth flagging. The first is dose: detox teas get drunk as a course, three mugs a day for a fortnight, which turns a moderate amount into a repeated one and can quietly unpick an elimination phase. The second is the swap that brings people here. Plenty of readers move to dandelion coffee because they suspect coffee is behind their symptoms, but black coffee records zero across all six FODMAP groups at its tested cup, so the trade takes them off a green drink and onto an amber one.
Gut-friendly ways to eat tea (dandelion)
If the roasted, bitter, coffee-ish note is what you are after, dandelion root is the wrong way to get it, because the root is the part carrying the inulin. Black coffee and instant coffee are both rated green, and decaf keeps the flavour while dropping the caffeine. If the point was simply a caffeine-free mug in the evening, peppermint tea is the steadier habit at 0.02 g of fructans a cup. Read blend ingredients as well, since dandelion hides inside liver and cleanse mixes that do not name it on the front.
Frequently asked questions
Is dandelion tea OK for IBS?
It is rated amber, meaning moderate rather than forbidden, and that is already at a weak brew of one 250 ml cup. How the tea gets drunk is the real issue. A cup now and then is a small question; three a day as part of a cleanse is a fructan load arriving on a schedule, and the people drinking it that way are often the ones with the touchiest guts.
Is dandelion coffee low FODMAP?
Roasted dandelion root is what most dandelion coffee is made from, and the root is where the inulin sits, so the roasting is not a way around the figures here. Only the tea has a tested serve in this guide, and it comes out amber. Before swapping, it is worth establishing whether coffee was ever your trigger, since the replacement carries fructans that coffee does not.
How much dandelion tea can I drink?
One weakly brewed cup is the only measured point, at 0.18 g of fructans and an amber rating, so there is no second figure to reason from. Nothing stronger, weaker or larger has been tested. Keeping to a single short-steeped cup, on a day when your other meals are not already fructan-heavy, is about as far as this data can take you.
Do detox teas trigger IBS?
Their ingredients decide it, and dandelion is one of the common ones. Chicory root shows up in the same blends and is another inulin-rich root, while the mixes sold for weight loss often include senna, a laxative herb, which is a separate matter from FODMAPs and worth knowing about. Read the ingredients panel rather than the claim on the front of the box.
