Monoammonium Glycyrrhizinate.

Strength pending.The research strength is not set yet.

The water-soluble salt of licorice's sweet active. In tiny amounts it sweetens and covers bitterness. In larger amounts it changes how the kidney handles cortisol, sodium and potassium.

What Monoammonium Glycyrrhizinate is, and what it does.

Does it work
Suits aqueous formulas that need sweetness without sugar. It suits people who keep total licorice intake modest and who keep an eye on potassium and blood pressure.
How much to take
No dose figure is on record here. There is a ceiling on record instead: several national authorities set daily glycyrrhizin guidance around 100 mg for the general population.
Time to feel it
Sweetness arrives slowly on the palate and lingers. The mineralocorticoid effect is cumulative over days to weeks rather than something a single serving produces.
The first dose
Day one is taste and nothing more: slow, sweet, distinctly licorice. The kidney effect needs repeated intake, so it doesn't show up on a first day.
With regular use
Weeks of intake above the guidance level show as sodium retention, rising urinary potassium and falling plasma renin and aldosterone. Those are lab readings, not sensations.
How well tolerated
Fine at the sweetener levels used in formulation. Intake stacks up across sweets, teas and supplements, and people watching blood pressure or potassium should ask a clinician.
How it feels
Very sweet with a long licorice tail. Some people find it comforting and others find it cloying. There's no other felt effect at formulation levels.
The overlooked benefit
Absorption depends on gut bacteria removing two sugar units first, so how much reaches your bloodstream is partly a property of your microbiome, not just the amount taken.

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.

Pairs well with9 on file

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.

Monoammonium Glycyrrhizinate + PotassiumEstablished endocrine pharmacology. Glycyrrhizin and its metabolite glycyrrhetinic acid inhibit renal 11-beta-hydroxysteroid dehydrogenase type 2, allowing cortisol to occupy the mineralocorticoid receptor, which retains sodium and increases urinary potassium loss.

This is the interaction that matters most for the ingredient and it works against potassium status. Regular intake over weeks drives potassium out in the urine, and adding potassium alongside does not remove the enzyme inhibition causing it. The effect scales with dose and duration rather than appearing after a single serving.

Monoammonium Glycyrrhizinate + SodiumThe same 11-beta-HSD2 inhibition, viewed from the sodium side, producing renal sodium reabsorption and extracellular volume expansion.

Sodium retention raises blood pressure, and a high dietary sodium load pushes in the same direction through the same route. The two stack rather than cancel. Several countries set daily glycyrrhizin intake ceilings for this reason.

Monoammonium Glycyrrhizinate + Licorice rootGlycyrrhizin is the principal saponin of Glycyrrhiza root and the monoammonium salt is that same active isolated and salified.

A product carrying both the salt and whole licorice root delivers one active from two label entries, and total daily glycyrrhizin is what governs the electrolyte effect. Formulators sometimes double up without noticing. Deglycyrrhizinated licorice is the exception because the active has been stripped out.

Monoammonium Glycyrrhizinate + Milk thistle silymarinLong-standing co-formulation in hepatic-support products across East Asia and Europe, supported by separate mechanistic work on each ingredient rather than on the combination.

Glycyrrhizin preparations are used clinically in China and Japan in the setting of elevated liver enzymes, and silymarin occupies a similar role in European practice. Both have antioxidant and membrane-stabilising mechanisms described in laboratory work. Head to head data on the pair against either alone is thin, so read the combination as convention with mechanistic support.

Monoammonium Glycyrrhizinate + GlutathioneBoth appear in formulas aimed at oxidative stress, and glycyrrhizin preparations have been described as raising antioxidant enzyme activity in animal work.

The perinatal cow study reported improvements in oxidative stress markers with monoammonium glycyrrhizinate, which is a marker-level finding in a non-human species. Glutathione operates in the same broad antioxidant network. The pairing is mechanistically coherent and untested in people.

Monoammonium Glycyrrhizinate + Vitamin EEstablished antioxidant network chemistry, with tocopherol covering the lipid phase and glycyrrhizin-associated effects described mainly in aqueous compartments.

Lipid and aqueous phase antioxidants cover different compartments and do not substitute for one another. Combining them is standard antioxidant formulation. This says nothing about clinical outcomes for either ingredient.

Monoammonium Glycyrrhizinate + Marshmallow rootTraditional pairing in demulcent throat and gastric preparations, resting on mucilage rather than any shared mechanism.

Marshmallow supplies viscous mucilage that physically coats mucosal surfaces, which is unrelated to what glycyrrhizin does. The pairing is old herbal practice. No controlled work has tested the combination.

Monoammonium Glycyrrhizinate + ChamomileFormulation convention in soothing herbal preparations, based on flavonoid content and traditional use.

The two co-occur in gastric and throat formulas across European herbal practice. Chamomile contributes apigenin and related flavonoids with their own laboratory literature. The combination has not been studied and any electrolyte considerations for glycyrrhizin still apply.

Monoammonium Glycyrrhizinate + GlycineEstablished formulation chemistry, with glycine used as a buffering and taste-modifying agent alongside intensely sweet glycyrrhizinate salts.

Glycyrrhizinate salts are added at low levels as sweeteners and bitterness maskers, and they leave a persistent licorice note. Glycine softens that finish and helps hold formulation pH. This is sensory and physical chemistry with no physiological implication.

What Monoammonium Glycyrrhizinate actually does.

Established

It blocks the kidney enzyme that switches cortisol off locally. Cortisol then behaves like a salt-retaining hormone, so sodium stays and potassium goes.

Established

Gut bacteria have to strip the sugars off before the active form gets absorbed, and that varies from person to person.

Established

The free acid barely dissolves. Making it an ammonium salt lets it go into water properly.

Established

Very sweet with a long finish, so tiny amounts go a long way as a flavour cover.

Grown, 6 steps on record

Where Monoammonium Glycyrrhizinate comes from.

Licorice root goes in, hot water pulls the active out, acid drops it into a solid, and ammonia turns that solid into something that dissolves in water. The result is a very sweet white powder that is the same active molecule found in licorice sweets.

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.

Starts as
Licorice root (Glycyrrhiza glabra, uralensis or inflata)

Roots and stolons from cultivated and wild stands in China, Uzbekistan, Turkey, Iran and Afghanistan. Glycyrrhizin runs at a few percent of dried root weight and varies by species and region.

Extracted by
Hot water or dilute alkaline extraction

Glycyrrhizin sits in the plant as calcium and potassium salts and is pulled into aqueous solution along with flavonoids and polysaccharides.

Purified by
Acid precipitation and recrystallisation

Acidifying the extract precipitates glycyrrhizic acid, which is filtered, washed and recrystallised to raise purity before salification.

Converted by
Neutralisation with ammonia

Reaction with ammonia converts the poorly soluble acid into the water-soluble monoammonium salt.

Standardised to
HPLC assay against a glycyrrhizin reference

Commercial material is typically specified at 98 percent or higher, with the assay reporting glycyrrhizin content rather than salt form.

Ends up as
White to pale yellow crystalline powder

Supplied for oral, topical, food and animal feed applications.

The forms it comes in.

Single ammonium saltOne ammonium counterion on the glycyrrhizic acid backbone, freely water-soluble at neutral pHFits Aqueous oral liquids, animal feed applications and flavour-masking in oral productsTrade-off Solubility declines as pH falls toward acid, and the ammonium ion contributes nothing beyond making the article dissolveActive and formulation aid
Double ammonium saltBoth carboxyl groups neutralised, giving higher aqueous solubility than the mono saltFits High-concentration liquid and injectable preparations used in East Asian clinical practiceTrade-off Higher ammonium load per gram, and the extra solubility only matters where concentration is the limiting factor
Potassium saltPotassium counterions, highly water-soluble, the standard cosmetic-grade articleFits Topical and skincare formulas needing an aqueous-soluble licorice activeTrade-off Brings potassium into the formula, which is a consideration in electrolyte-sensitive compositionsActive and formulation aid
Stereoisomeric magnesium saltThe 18-alpha stereoisomer as a magnesium salt, a different spatial arrangement from the naturally occurring 18-beta formFits Clinical preparations in China where the isomer is specified by pharmacopoeiaTrade-off Being a different stereoisomer, data generated on 18-beta glycyrrhizin does not transfer to it directly
Free acidUnsalified parent compound with poor cold-water solubilityFits Dry blends and powdered extracts where dissolution is not neededTrade-off Unusable in aqueous liquids without salification, which is the whole reason the salts are made
DGLLicorice extract with glycyrrhizin removed, leaving flavonoids and polysaccharidesFits Formulas wanting licorice constituents without the mineralocorticoid mechanismTrade-off It is licorice with this active removed rather than a form of it, so anything that depends on glycyrrhizin will not happen
