Does dandelion root tea affect iron absorption?

No trial has tested dandelion root tea's effect on iron absorption or on iron-deficiency anemia, in either direction. The plant supplies only a modest amount of iron itself, and a documented case involving ordinary tea raises a related question for polyphenol-containing beverages generally — but it hasn't been tested for dandelion specifically.

What the evidence doesn't support

It doesn't support drinking dandelion root tea as a way to get meaningful iron. It doesn't support, or rule out, dandelion tea interfering with iron absorption from food or supplements — that specific test hasn't been run. And it doesn't support dandelion root as a treatment for iron-deficiency anemia, which is a diagnosis for a doctor to manage, not something a tea or supplement addresses.

What the trials found

USDA composition data lists about 3.1 mg of iron per 100 g of raw dandelion greens — roughly 17% of a typical daily target for the fresh vegetable. There's no comparable published figure for dried dandelion root, the part sold as tea and capsules, and a typical serving (a gram or two of cut root per cup of tea) is a small fraction of 100 g to begin with.

Separately, a 1995 case report described a young woman with iron-deficiency anemia who did not respond to oral iron treatment until she cut back on a long-standing habit of drinking large amounts of tea. The authors explain that tea's tannins are documented to reduce absorption of non-heme (plant-form) iron specifically, while heme iron from meat is not appreciably affected, and they advise against taking oral iron supplements together with tea. That case involved ordinary black tea (Camellia sinensis), not dandelion root tea, and it's a single case report — not a trial, and not evidence about dandelion's own polyphenol content one way or the other.

No study has measured dandelion root tea against iron absorption directly, so there's no way to say whether the same tannin-related caution applies to it, applies less, or doesn't apply at all.

Questions people ask

How much iron is in dandelion root tea?

No published analysis measures iron in dandelion root tea specifically. The closest figure — fresh dandelion greens, not root — shows a modest amount per 100 g, and a cup of tea uses only a gram or two of dried root.

Does dandelion root tea help with anemia?

No trial has tested that use. Iron-deficiency anemia is a diagnosis that needs medical evaluation and, usually, iron supplementation prescribed and monitored by a doctor — not a tea or supplement addressed on this page.

Should I avoid dandelion tea if I'm taking an iron supplement?

That's a reasonable question to raise with a doctor or pharmacist given the documented tannin-iron interaction for tea generally, even though dandelion tea itself hasn't been tested for it. Spacing any tea away from an iron dose is a common, low-cost precaution some clinicians recommend regardless of tea type.

When to talk to a doctor

Iron-deficiency anemia, or an iron supplement that doesn't seem to be working, is worth bringing to a doctor rather than adjusting on your own. Dandelion root tea is not a treatment for anemia, and nothing in the evidence above supports using it as one, alone or alongside iron therapy.
