Corosolic Acid in Memo Volt: Banaba Leaf and Blood Sugar
A banaba-leaf compound that lowers blood sugar, studied at 10-48mg per day.
Corosolic acid is a compound from the leaves of the banaba tree, Lagerstroemia speciosa, used in Southeast Asia as a traditional blood sugar remedy. Small human studies at 10 to 48mg a day of standardised extract report modest reductions in blood glucose.
It has no cognitive research, and it is one of four ingredients in this formula that lower blood sugar.

What corosolic acid is
Banaba is a flowering tree found across Southeast Asia, and its leaves have been brewed as a tea for blood sugar for generations. Corosolic acid is the compound most credited with that effect, and supplement extracts are usually standardised to a percentage of it.
Unlike most ingredients in this formula, the research dose is small enough that a capsule could realistically contain a meaningful amount — 10 to 48mg is achievable alongside other ingredients.
What the research actually shows
Several small human studies have reported that banaba leaf extract lowers blood glucose, particularly after a meal. The doses were modest and the studies were small, short and not widely replicated. It is early-stage evidence, not settled science.
There is no research on corosolic acid and memory, attention or cognitive performance. This is another metabolic ingredient in a product sold for the brain.
The stacking problem
Corosolic acid lowers blood sugar. So does berberine. So does oleuropein. So does Ceylon cinnamon. That is four of the ten ingredients acting on the same system.
Individually each is mild. Together, in someone already taking metformin, a sulfonylurea or insulin, that stacking is the most realistic safety concern in the whole formula — more realistic than any single ingredient on its own.
The bottom line on Corosolic Acid
One of the few ingredients here whose research dose a capsule could actually deliver. Its evidence is early and its effect is metabolic, not cognitive — and it adds to a blood-sugar stack that people on diabetes medicine need to take seriously.
Remember what this page is. Everything above is about Corosolic Acid as a compound, at the doses used in its own research. It is not evidence about Memo Volt, because Memo Volt does not publish how much of it a capsule contains. Research on an ingredient is never the same thing as evidence about a finished product.
Corosolic Acid: common questions
Small human studies suggest it lowers blood glucose, particularly after meals. It comes from banaba leaf, used traditionally in Southeast Asia for blood sugar. There is no cognitive research on it.
Not without asking your prescriber. Both lower blood sugar, and combining them can push it too low. This formula contains three other blood-sugar ingredients as well, which compounds the issue.
At the doses used in studies it has been generally well tolerated. The main practical risk is additive blood sugar lowering if you take diabetes medicine.
