Banaba Leaf In GlycoAid
A Philippine tree leaf carrying corosolic acid, drunk as tea for generations.
What It Is
The leaf of Lagerstroemia speciosa, a flowering tree across the Philippines and Southeast Asia, where it has been drunk as a tea for generations.
What it is studied for
Glucose uptake, on a handful of small human trials with generally positive findings and nothing like the volume behind berberine.
Evidence grade: Moderate. Several human studies exist, generally small ones, and the findings are less settled than for the large-evidence items on this panel.
The compound of interest
Corosolic acid, a triterpenoid studied for its effect on how cells take up glucose. Extracts are usually standardised to a percentage of it.
The Dose Question
Typical protocols give 30 to 50 mg daily of an extract standardised at one or two percent corosolic acid. Neither figure appears on the GlycoAid label: not the quantity, not the standardisation.
Banaba Leaf On The GlycoAid Label
| Most studied for | Glucose uptake |
|---|---|
| Key compound | Corosolic acid |
| Typical research dose | 30–50 mg standardised extract |
| Amount here | Not published; inside the 500 mg blend |
| Standardisation | Not stated on the label |
Cautions
Banaba leaf is well tolerated at supplement intakes. Because it is studied for glucose uptake it belongs in the conversation with any clinician managing blood sugar medication.
Questions About Banaba Leaf
Corosolic acid is what?
The triterpenoid in banaba leaf that most of the research concerns.
Is banaba leaf well studied?
Moderately. Several small human trials rather than the large body behind berberine.
Does the label give a standardisation?
No. The blend declares one combined weight and no percentages.
Is it the same as banaba tea?
The same plant, a different preparation. A cup of tea and a standardised extract are not the same quantity.
Judging It Fairly
No single item on this panel can be assessed from the outside on its own, and no single week of taking the capsule settles anything either. What week one is actually measuring takes that apart properly.
Where It Sits In The Formula
Banaba Leaf is printed inside one 500 mg proprietary formulation alongside thirteen other items, so the amount here is unknown. That is the honest position on every panel page on this site, and it is why where the 500 milligrams goes is worth ten minutes. The item before this one on the label is Gymnema Sylvestre and the one after it is Bitter Melon.
