Steady support for blood sugar after meals
Blood Sugar Health Banaba & Ginkgo Complex pairs Banaba leaf extract, standardised for Corosolic acid, with Ginkgo Biloba, zinc, selenium and vitamin B6. One tablet a day, made in Korea, built around a single approved function claim: it may help inhibit the rise in blood glucose after meals.
What this formula is designed to support
Six areas of everyday support, built around one officially approved function claim and evidence stated exactly as it stands.
Blood sugar after meals
Banaba leaf extract, standardised to 1.3 mg of Corosolic acid per tablet, may help inhibit the rise in blood glucose after meals. This is the product's one officially approved function claim.
Microcirculation
The flavonoids in Ginkgo Biloba, such as quercetin and kaempferol, help support the regulation of platelet aggregation and the protection of the smallest blood vessels.
Antioxidant defence
Ginkgo Biloba supports the Nrf2/HO-1 antioxidant pathway and the clearing of free radicals, helping to limit the cell damage associated with high blood glucose.
Broader metabolic balance
Beyond glucose, Corosolic acid has also been reported to support healthier cholesterol and triglyceride levels by increasing PPAR-alpha expression and fatty-acid beta-oxidation.
Essential micronutrients
Zinc contributes to the synthesis, storage and secretion of insulin by the pancreatic beta cells, while selenium and vitamin B6 support antioxidant defence and energy metabolism.
Looking after the long term
Ginkgo Biloba supports circulation and antioxidant defence — the direction research associates with long-term complication risk. It does not lower blood glucose directly.
Corosolic acid: three actions in one
Banaba does not work through a single route, but through three that meet at the same point.
Opening the door of the cell
Corosolic acid supports GLUT4 transport, helping move glucose out of the bloodstream and into muscle and other cells, which contributes to better insulin sensitivity.
Slowing how fast sugar enters the blood
It helps inhibit alpha-glucosidase and alpha-amylase (sucrase), slowing the breakdown of starch in the gut. The result is a gentler peak in blood glucose after a meal.
Easing the sugar the body makes
It helps reduce gluconeogenesis, the production of new glucose in the liver, while supporting glycolysis, the breakdown of glucose for energy.
Because these three actions work at the same time, the support covers where glucose comes from, how quickly it arrives and how well it is taken up.
Four tiers in a single 600 mg tablet
Each tier has a defined job, and none of them is asked to do more than the evidence allows.
Banaba leaf extract (Lagerstroemia speciosa L.)
The core active of the formula, acting on glucose metabolism. It may help inhibit the rise in blood glucose after meals.
Ginkgo Biloba leaf extract
Provides antioxidant action and helps protect the microcirculation — the direction associated with long-term complication risk. It does not lower blood glucose directly.
Zinc · Selenium · Vitamin B6
Three nutrients that underpin insulin handling, antioxidant enzyme activity and energy metabolism, filling gaps a plant extract alone cannot cover.
Red ginseng, bitter melon, grape seed, gotu kola, Jerusalem artichoke, oat
Six familiar botanicals that give the formula its character and heritage. They are included in a supporting role only, and no clinical efficacy is claimed for them.
What is inside each 600 mg tablet
Five quantified actives and six supporting botanicals, listed with their exact amounts.
Banaba leaf extract (Lagerstroemia speciosa L.)
The lead ingredient, standardised for Corosolic acid. It may help inhibit the rise in blood glucose after meals, acting on glucose metabolism through three complementary routes.
Ginkgo Biloba leaf extract
A strong antioxidant that supports the Nrf2/HO-1 pathway and helps protect small blood vessels; it does not lower blood glucose directly. Standardised EGb 761 extract typically contains around 24% flavonol glycosides and 6% terpene lactones.
Zinc
Needed for the synthesis, storage and secretion of insulin by the pancreatic beta cells. It also contributes to antioxidant defence, normal immune function and wound healing.
Selenium
A component of the antioxidant enzyme glutathione peroxidase (GPx), which helps protect cells from oxidative stress. It works in concert with the antioxidant action of Ginkgo Biloba.
Vitamin B6
Involved in red blood cell formation, energy metabolism and mood regulation. It also supports the synthesis of neurotransmitters.
What the human studies actually found
Sample sizes, doses, durations and outcomes are quoted exactly as published — nothing rounded up, nothing dressed up.
💡 Key takeaways
- Banaba's effect on post-meal glucose has been observed at a dose as low as 1 mg of Corosolic acid per day, in a randomised, double-blind, placebo-controlled crossover trial.
- Ginkgo Biloba was studied as an addition to standard medication, and the benefits reported were antioxidant, metabolic and vascular — not a direct glucose-lowering action of its own.
- These are small, early-stage human studies. This product is a health functional food with a supporting role: it does not treat or cure disease, and it does not replace the medication your doctor has prescribed.
Where Ginkgo Biloba points — and how strong the evidence is
Each direction is stated at the level of evidence that actually stands behind it. None of it is a treatment claim.
Kidneys
In laboratory and animal research, Ginkgo Biloba has shown protective effects through the inhibition of NLRP3-driven inflammation, increased Nrf2/HO-1 activity and reduced kidney fibrosis. This evidence is PRECLINICAL and has not been confirmed in human trials.
Peripheral nerves
There is suggestive data that Ginkgo Biloba may help support the reduction of nerve damage in people living with diabetes. The signal is encouraging rather than conclusive.
Eyes and retina
Ginkgo Biloba has been reported to improve blood flow in the retinal capillaries, which supports the protection of the delicate microcirculation at the back of the eye.
Heart and blood vessels
By supporting circulation, Ginkgo Biloba is linked with a favourable direction for large-vessel complication risk. In a study by Kudolo, EGb 761 at 120 mg per day for three months (n=12) reduced platelet activation measured as TXB2 (p < 0.05).
