Managing blood sugar levels is crucial for maintaining overall health, particularly for individuals with diabetes or prediabetes. While medications and lifestyle changes are essential, certain teas can also support blood sugar regulation. In this article, we explore the 10 best teas known for their potential to lower blood sugar, backed by scientific evidence and traditional knowledge.
10 Best Teas to Lower Blood Sugar
1. Green Tea
Overview
Green tea, derived from the leaves of the Camellia sinensis plant, is renowned for its health benefits, including its ability to lower blood sugar levels.
Active Compounds
The key bioactive compounds in green tea are catechins, particularly epigallocatechin gallate (EGCG), which have potent antioxidant and anti-inflammatory properties.
Benefits for Blood Sugar
Green tea has been shown to improve insulin sensitivity and reduce blood sugar levels. It enhances glucose metabolism and helps regulate the body’s use of insulin, thereby stabilizing blood sugar.
Scientific Evidence
Several studies have demonstrated that regular consumption of green tea can lower fasting blood sugar levels and improve HbA1c levels, a marker of long-term blood sugar control.
2. Cinnamon Tea
Overview
Cinnamon tea, made from the bark of the Cinnamomum tree, is a flavorful and aromatic tea with significant health benefits, particularly for blood sugar management.
Active Compounds
Cinnamon contains cinnamaldehyde, which has been shown to mimic insulin and increase glucose uptake by cells. It also contains polyphenols that have antioxidant properties.
Benefits for Blood Sugar
Cinnamon tea can improve insulin sensitivity, reduce insulin resistance, and lower fasting blood sugar levels. It also slows the breakdown of carbohydrates in the digestive tract, reducing postprandial blood sugar spikes.
Scientific Evidence
Research indicates that cinnamon supplementation can reduce fasting blood glucose and improve HbA1c levels. A meta-analysis of several studies confirmed cinnamon’s beneficial effects on blood sugar control.
3. Hibiscus Tea
Overview
Hibiscus tea, made from the dried petals of the Hibiscus sabdariffa plant, is a vibrant and tangy tea with numerous health benefits, including blood sugar regulation.
Active Compounds

Benefits for Blood Sugar
Hibiscus tea has been shown to reduce blood sugar levels by enhancing insulin sensitivity and inhibiting the activity of enzymes involved in carbohydrate digestion.
Scientific Evidence
Studies have found that hibiscus tea can significantly lower fasting blood glucose levels and improve lipid profiles in individuals with diabetes.
4. Chamomile Tea
Overview
Chamomile tea, made from the flowers of the Matricaria chamomilla plant, is well-known for its calming effects and health benefits, including its potential to lower blood sugar levels.
Active Compounds
Chamomile contains flavonoids such as apigenin, which have anti-inflammatory and antioxidant properties.
Benefits for Blood Sugar
Chamomile tea helps improve insulin sensitivity, reduce blood sugar levels, and decrease the risk of complications associated with diabetes by inhibiting the activity of enzymes involved in glucose production.
Scientific Evidence
Research indicates that regular consumption of chamomile tea can significantly reduce fasting blood sugar levels and improve HbA1c levels in individuals with diabetes.
5. Ginger Tea
Overview
Ginger tea, made from the root of the Zingiber officinale plant, is a spicy and aromatic tea with a range of health benefits, including blood sugar regulation.
Active Compounds
Ginger contains gingerols and shogaols, which have anti-inflammatory and antioxidant properties.
Benefits for Blood Sugar
Ginger tea can enhance insulin sensitivity, improve glucose uptake by cells, and reduce fasting blood sugar levels. It also has a beneficial effect on lipid metabolism.
Scientific Evidence
Studies have shown that ginger supplementation can significantly reduce fasting blood sugar levels and improve insulin resistance in individuals with type 2 diabetes.
6. Peppermint Tea
Overview
Peppermint tea, made from the leaves of the Mentha piperita plant, is a refreshing and soothing tea with potential benefits for blood sugar control.
Active Compounds
Peppermint contains menthol, rosmarinic acid, and flavonoids, which have anti-inflammatory and antioxidant properties.
Benefits for Blood Sugar
Peppermint tea can help lower blood sugar levels by improving insulin sensitivity and reducing oxidative stress, which is linked to insulin resistance.
Scientific Evidence
Research on the direct effects of peppermint tea on blood sugar levels is limited, but its active compounds have shown potential in improving insulin sensitivity and reducing oxidative stress.
7. Rooibos Tea
Overview
Rooibos tea, made from the leaves of the Aspalathus linearis plant, is a caffeine-free herbal tea with numerous health benefits, including blood sugar regulation.
Active Compounds
Rooibos contains aspalathin, a unique flavonoid with potent antioxidant and anti-diabetic properties.
Benefits for Blood Sugar
Rooibos tea can improve insulin sensitivity, reduce fasting blood sugar levels, and protect pancreatic beta cells from oxidative damage.
Scientific Evidence
Studies have demonstrated that rooibos tea and its active compounds can lower fasting blood sugar levels and improve glucose tolerance in animal models. Human studies are needed to confirm these effects.
8. Fenugreek Tea
Overview
Fenugreek tea, made from the seeds of the Trigonella foenum-graecum plant, is a traditional herbal tea with significant benefits for blood sugar control.
Active Compounds
Fenugreek contains soluble fiber, galactomannan, and compounds such as 4-hydroxyisoleucine, which have insulin-mimetic properties.
Benefits for Blood Sugar
Fenugreek tea can improve insulin sensitivity, reduce fasting blood sugar levels, and slow the absorption of carbohydrates in the digestive tract.
Scientific Evidence
Clinical studies have shown that fenugreek supplementation can significantly reduce fasting blood sugar levels and improve HbA1c levels in individuals with diabetes.
9. Bilberry Tea
Overview
Bilberry tea, made from the leaves and berries of the Vaccinium myrtillus plant, is a traditional remedy with potential benefits for blood sugar regulation.
