List of Teas for Diabetes
Let’s have a look at a list of the 6 best teas for diabetes.
1. Green Tea
Green tea is a type of tea that is made from unoxidized leaves. It is traditionally used for improving mental alertness and aiding in digestion. A study by Liu et al. (2014) examined the effects of green tea extract on insulin resistance and glucagon-like peptide 1 in patients with type 2 diabetes and lipid abnormalities. The results showed beneficial impacts on glycemic and lipid profiles.
To craft a soothing cup of green tea, submerge a teaspoon of green tea leaves in 175°F or 80°C water, let it sit for 1-3 minutes, then sieve and partake. If you want to know more about the other health benefits of green tea, check out our article on green tea benefits!
2. Oolong Tea
Oolong tea is partially fermented and is somewhere between green tea and black tea in terms of oxidation and flavor. It is generally consumed to improve heart health and to provide a mental boost. A study by Chen et al. (2009) investigated the antioxidant capacity of polysaccharides from green tea, oolong tea, and black tea, which is beneficial for individuals with diabetes.
One to two cups of oolong tea a day can help. Steep 1 teaspoon of oolong tea leaves for 3 to 5 minutes in hot water. If you want to know more about the other health benefits of oolong tea, check out our article on the oolong tea benefits!
3. Black Tea
Black tea is fully oxidized, giving it a dark color and rich flavor. It has been consumed to increase alertness and improve digestive health. The study by Chen et al. (2009) also highlighted that black tea’s polysaccharides exhibited antioxidant activity, beneficial for diabetes.
To make it, infuse a teaspoonful of black tea leaves in a cup of boiling water (around 212°F or 100°C), wait for 3-5 minutes, then pour through a strainer and delight in your brew. If you want to know more, have a look at our article on black tea benefits!

4. White Tea
White tea is minimally processed and harvested when the tea plant is young. It has traditionally been used for its anti-aging properties and as a source of antioxidants.
While white tea has not been extensively studied for its effects on diabetes, it shares some of the beneficial antioxidants found in green tea, which are useful for people with diabetes (Chen et al., 2009). Drinking one cup of white tea a day can be a healthy addition.
To prepare, steep 1 teaspoon of white tea leaves in hot water for 4 to 5 minutes. If you want to know more about the other health benefits of white tea, check out our article on the benefits of white tea!
5. Herbal Teas for Diabetes
Herbal teas like fenugreek, cinnamon, and ginger tea are caffeine-free alternatives to traditional teas. These teas are often used for their digestive, anti-inflammatory, and blood sugar-lowering effects. While not directly referenced in the studies, herbal teas have long been associated with blood sugar management, which makes them one of the good teas for diabetes prevention (Liu et al., 2018).
6. Rooibos Tea
Rooibos tea is a caffeine-free herbal tea originating from South Africa. It is often consumed to relieve stress, improve digestive health, and support the immune system. Rooibos tea has not been a focus of studies regarding diabetes, but its anti-inflammatory and antioxidant properties are generally considered beneficial for metabolic health, including diabetes (Liu et al., 2018).
To make this tea, steep a tablespoon of organic red rooibos in a cup of boiling water for 5-7 minutes, then strain and savor. If you want to know more about the other health benefits of rooibos tea, check out our article on the benefits of rooibos tea!

Frequently Asked Questions
What is the best tea for diabetes?
Among various options, green tea stands out as the best tea for diabetes. Multiple scientific studies, including those by Chen et al. (2009) and Liu et al. (2014), have demonstrated that green tea can have a positive effect on insulin sensitivity and blood sugar levels. It’s rich in antioxidants and has been shown to help improve glycemic and lipid profiles in type 2 diabetes patients. Therefore, incorporating green tea into a diabetes management plan can offer significant benefits.
What can diabetics put in their tea?
For individuals managing diabetes, it’s crucial to avoid sugar and high-calorie sweeteners. Natural options like stevia can offer a sweet touch without affecting blood sugar levels.
