Lady's Mantle.
A tannin rich meadow herb used in European practice as an astringent. Its tannins bind proteins on contact, which is the drying, puckering effect the herb is known for.

What Lady's Mantle is, and what it does.
- Does it work
- Suits people drawn to traditional European herbal teas and topical astringent washes. Modern human research is thin, with 100 records at Europe PMC.
- How much to take
- No dose figure is on record for this herb. Traditional use is a cup of tea from the dried aerial parts. Start low, and keep it away from mineral supplements.
- Time to feel it
- The astringent mouthfeel is immediate. Anything beyond that has not been measured in people well enough to put a timeline on it.
- The first dose
- You taste the astringency straight away, a dry pucker like very strong tea. Beyond that, day one is quiet.
- With regular use
- Regular use keeps the tannin exposure going, and gut bacteria convert its ellagitannins into urolithins. What weeks of that do in people has not been measured.
- How well tolerated
- Generally well tolerated as a tea. Its tannins bind iron and protein, so space it from mineral supplements and protein meals. In pregnancy, take it only on clinical advice.
- How it feels
- Dry and puckering, like strong black tea. That astringency is the herb doing the thing it is traditionally used for, and it is most of the felt experience.
- The overlooked benefit
- Alchemilla vulgaris is not one plant but hundreds of near identical microspecies, so a supplier who names its origin is telling you something that matters.
The proof, claim by claim.
These words describe the research, not the molecule's worth. Research strength is how much work stands behind one claim, and it is never a product score.

Why these belong in the same formula. Each row says what the basis is, from settled biochemistry through to a trial that measured the pair.
This is the same mechanism by which strong tea reduces iron uptake from a meal, and it is one of the better characterised food interactions in nutrition. Separating the two by a couple of hours largely avoids it. The effect is on absorption from that meal, not on iron stores directly.
Stacking tannin sources raises the total protein and mineral binding capacity in the gut. That increases astringency and the likelihood of gastric discomfort. Worth counting as one load rather than two ingredients.
The evidence base for zinc is thinner than for iron but the chemistry is the same. Anyone taking a tannin rich herbal preparation with a mineral supplement should space them. This is a timing point, not a reason to avoid either.
Tannin protein complexes form readily in the stomach and reduce the protein available for digestion in that meal. The size of the effect at herbal tea intakes is modest. It is more relevant to the mouthfeel of a formulation than to nutrition.
This is the standard countermeasure when a tannin rich beverage or herb is taken with a plant iron source. It does not fully cancel strong tannin inhibition but it shifts the balance meaningfully. The interaction is well described for tea and coffee and applies by the same chemistry here.
Long usage supports tolerability but says nothing about efficacy. No controlled work has separated the components of these traditional blends. The pairing is heritage and should be described as such.
The rationale is mechanically sensible: mucilage coats, tannin contracts. Neither the combination nor its individual claims have been tested in controlled human work. Regard it as formulation convention with a plausible physical basis.
Combining two polyphenol dense preparations multiplies the astringency and the mineral binding without any established added benefit. Concentrated green tea extract also carries its own hepatic caution at high doses. Count the total polyphenol load, not the number of ingredients.
Both are conjugated by the same phase two glucuronidation and sulfation routes, which are saturable. The amounts from a herbal infusion are small next to a supplemental quercetin dose. This is dose accounting rather than a meaningful interaction.
The binding affinity of hydrolysable tannins for proline rich sequences is the classic model system in tannin chemistry. Complexed peptide is less available for absorption in that meal. Spacing the two apart resolves it.

This is the above-ground part of a European meadow herb, dominated by a class of tannins.
These tannins bind and clump proteins together, especially certain protein sequences, and that protein-binding is the chemical reason behind the dry, puckering feel and the traditional use of astringent herbs on mucous surfaces.
Gut bacteria convert these tannins into other compounds, and how much conversion happens varies a lot between people depending on their gut bacteria, so the same intake can lead to very different exposure to those compounds.
Tannins also grab onto minerals in the gut, forming complexes that are poorly absorbed, which is the mechanism behind lower iron absorption seen with tannin-rich drinks.
Where Lady's Mantle comes from.
Lady's mantle is a small meadow plant with pleated leaves that hold dew, used in European herbal practice for centuries. What it mostly contains is tannins, the same class of astringent compounds that make strong tea pucker your mouth. That astringency is the traditional point of the herb, and it is also why it binds iron and protein in the gut, so space it away from mineral supplements and protein meals. One quirk worth knowing: what botanists call Alchemilla vulgaris is actually hundreds of near identical microspecies, which makes verifying what is in the bag harder than usual.
Made from a plant. What ends up in the capsule tracks the harvest, so batch testing and a stated marker matter more here than with a made molecule.
Leaf and flowering top of a low growing perennial of European and western Asian meadows and hill pasture. The plant is an apomictic aggregate of many microspecies, so botanical verification of commercial material is genuinely difficult.
Aerial parts are cut during flowering and dried in shade at moderate temperature. Tannin content is highest around flowering and falls with slow or hot drying.
Hot water recovers the polar tannins and glycosides. Ethanol and water together recover a wider range, including less polar flavonoids and sterols. Neither is a superset of the other.
Liquid extract is concentrated under vacuum at low temperature, since hydrolysable tannins degrade with heat, then spray or vacuum dried onto a carrier.
Material is typically assayed for total tannin content expressed as pyrogallol equivalents, following pharmacopoeial method. This measures quantity rather than identity of the tannins present.
Sold as loose dried herb for infusion, as an ethanolic tincture, as a standardised dry extract in capsules, and incorporated into topical washes and creams.
