Banaba Leaf In GlycoAid
A Philippine tree leaf carrying corosolic acid, brewed as tea for generations.

Where It Comes From
Leaf of Lagerstroemia speciosa, a flowering tree found across the Philippines and Southeast Asia, where it has been brewed as a tea for generations.
What the research is about
Glucose uptake, across a handful of small human trials with broadly positive findings and nothing approaching the volume behind berberine.
The compound the research is about
Corosolic acid, a triterpenoid studied for its effect on how cells take glucose in. Extracts are normally standardised to a stated percentage of it.
Evidence grade: Moderate. Several human studies exist, generally small, and the findings are less settled than for the large-file names on this panel.
Fast Facts
| Deepest file for | Glucose uptake |
|---|---|
| Compound of interest | Corosolic acid |
| Usual study quantity | 30–50 mg standardised extract |
| Quantity here | Undisclosed, inside the 500 mg total |
| Standardisation | Not stated on the panel |
The Quantity Question
Protocols commonly give 30 to 50 mg daily of an extract standardised at one or two percent corosolic acid. This panel publishes neither the quantity nor the standardisation.
Cautions
Banaba leaf is tolerated well at supplement quantities. Because the research concerns glucose uptake, it belongs in any conversation with a clinician managing blood sugar medication.
Questions About Banaba Leaf
Corosolic acid does what?
The triterpenoid in banaba leaf that the research concerns itself with.
How well studied is it?
Moderately. Several small human trials rather than the body of work behind berberine.
Does the panel give a standardisation?
It does not. One combined weight and no percentages.
Is this the same as banaba tea?
Same plant, different preparation. A cup of tea and a standardised extract are not comparable quantities.
How It Sits In The Blend
Banaba Leaf is printed inside one 500 mg proprietary formulation alongside thirteen other names, so the quantity here is unknown. That is the position on every panel page on this site, and 500 mg, divided works through what that arithmetic permits. The name above it on the panel is Gymnema Sylvestre and the one below is Bitter Melon.
