Lagerstroemia Speciosa Leaf Extract
Also known as: Banaba Leaf Extract, Lagerstroemia speciosa extract, Lagerstroemia speciosa Leaf Extract
Overview
Lagerstroemia speciosa, commonly known as banaba, is a plant traditionally used for its medicinal properties. The leaf extract is derived from the leaves of the Lagerstroemia speciosa tree and is recognized for its potential antidiabetic, anti-obesity, antioxidant, and anti-inflammatory effects. Key compounds found in the extract, such as corosolic acid and ellagitannins like penta-O-galloyl-glucopyranose (PGG), are believed to contribute to these beneficial effects. It is available in various forms, including capsules, tablets, and powders, and is often marketed as a dietary supplement. Research suggests that it may help in managing blood sugar levels, reducing body weight, and preventing chronic diseases. However, more extensive human clinical trials are needed to confirm these findings and ensure its safe use.
Benefits
Lagerstroemia speciosa leaf extract is primarily known for its antidiabetic and anti-obesity effects. Studies suggest that it can improve insulin sensitivity and glucose uptake in cells, mainly due to compounds like corosolic acid and PGG. Research indicates that PGG stimulates glucose uptake in adipocytes and inhibits adipocyte differentiation, which may aid in weight management. Additionally, the extract exhibits antioxidant and anti-inflammatory properties, potentially reducing the risk of chronic diseases. Animal studies have also shown that it can inhibit lung tumorigenesis by reducing oxidative stress and inflammation. However, further research is needed to confirm these benefits in humans and determine optimal dosages.
How it works
Lagerstroemia speciosa leaf extract exerts its effects through several mechanisms. Key compounds like corosolic acid and PGG enhance insulin sensitivity and stimulate glucose uptake in cells, particularly adipocytes. PGG inhibits adipocyte differentiation, reducing fat accumulation. The extract's antioxidant properties help neutralize free radicals, reducing oxidative stress and inflammation. These actions collectively contribute to its antidiabetic, anti-obesity, and anti-inflammatory effects. The extract interacts with various biological pathways involved in glucose metabolism, adipogenesis, and oxidative stress, promoting overall metabolic health.
Side effects
While generally considered safe, Lagerstroemia speciosa leaf extract may cause some side effects. The most common adverse effects include mild gastrointestinal issues such as nausea, diarrhea, and stomach upset. Due to its potential to lower blood sugar levels, individuals with diabetes or those taking antidiabetic medications should use it with caution, as it may increase the risk of hypoglycemia. It is also advisable to monitor blood sugar levels regularly. There is limited information on its safety during pregnancy and breastfeeding, so it is best avoided during these periods. Individuals with known allergies to plants in the Lythraceae family should also exercise caution. Always consult with a healthcare professional before starting any new supplement, especially if you have underlying health conditions or are taking other medications.
Dosage
The recommended dosage of Lagerstroemia speciosa leaf extract varies depending on the specific product and its concentration of active compounds. A typical dosage ranges from 300 to 500 mg per day, often divided into multiple doses. It is usually taken with meals to enhance absorption and minimize potential gastrointestinal discomfort. For managing blood sugar levels, it is crucial to monitor glucose levels regularly and adjust the dosage accordingly, especially for individuals with diabetes. There is no established upper limit, but exceeding the recommended dosage may increase the risk of side effects. Always follow the product label instructions and consult with a healthcare professional to determine the appropriate dosage for your individual needs.
FAQs
What is Lagerstroemia speciosa leaf extract used for?
It is primarily used for its potential antidiabetic and anti-obesity effects. It may help manage blood sugar levels, reduce body weight, and provide antioxidant and anti-inflammatory benefits.
How quickly does it start working?
The onset of effects can vary. Some users may notice improvements in blood sugar levels within a few weeks, while others may require several months to see noticeable changes. Consistency in dosage is important.
Is it safe to take with other medications?
It may interact with antidiabetic medications, increasing the risk of hypoglycemia. Consult with a healthcare professional before combining it with other drugs, especially if you have underlying health conditions.
Are there any long-term side effects?
Long-term safety data is limited. Most reported side effects are mild and gastrointestinal in nature. Monitor for any adverse reactions and discontinue use if necessary.
Can pregnant or breastfeeding women use it?
There is limited information on its safety during pregnancy and breastfeeding. It is best to avoid using it during these periods to ensure the safety of both mother and child.

The extract was found to attenuate lung tumorigenesis by reducing oxidative stress, inflammation, and apoptosis, suggesting its potential as a chemopreventive agent.
- https://pubmed.ncbi.nlm.nih.gov/18227906/ – This research focuses on the anti-obesity effects of penta-O-galloyl-glucopyranose (PGG), a component of banaba extract. The study demonstrates that PGG has significant anti-adipogenic properties, making it a potential therapeutic agent for obesity management by inhibiting adipocyte differentiation.
- https://pubmed.ncbi.nlm.nih.gov/22095937/ – This study investigates the effects of corosolic acid, a key component of banaba extract, on glucose transport in adipocytes. The findings suggest that corosolic acid enhances glucose uptake, contributing to the antidiabetic properties of Lagerstroemia speciosa.
- https://pubmed.ncbi.nlm.nih.gov/11533261/ – This research examines the insulin-like glucose uptake activity of banaba extract in 3T3-L1 adipocytes. The study demonstrates that banaba extract stimulates glucose uptake similar to insulin but does not induce adipocyte differentiation, unlike insulin, suggesting a potential benefit for managing diabetes without promoting fat accumulation.
