How Milk in Tea May Block Stroke-Preventing Antioxidants
Tea is one of the most widely consumed beverages in the world and is well-known for its health benefits, thanks to its abundance of powerful antioxidants like catechins and flavonoids. These compounds have been shown to reduce inflammation, protect blood vessels, and decrease the risk of cardiovascular diseases, including stroke. But if you’re among the millions who enjoy a splash of milk in your tea, you may be unknowingly limiting its stroke-preventing benefits.
The Antioxidant Power of Tea
Tea’s health-boosting properties largely come from polyphenols, a group of powerful antioxidants found in both green and black tea. These compounds:
- fight oxidative stress
- lower blood pressure
- reduce bad cholesterol levels
all of which play a vital role in reducing stroke risk. The catechins found in tea, especially in green tea, are key to this process as they help to neutralize free radicals that damage cells and blood vessels, contributing to stroke prevention.
How Milk Interacts with Tea’s Antioxidants
When milk is added to tea, proteins known as caseins in the milk bind with tea’s polyphenols, including catechins. This bond can reduce the antioxidants’ effectiveness, which is essential for their stroke-preventing benefits. Research suggests that caseins may alter the structure of these antioxidants, preventing them from being absorbed in the digestive tract as they normally would, thus diminishing the health benefits that tea provides.
The Evidence Behind Milk’s Impact on Tea’s Health Benefits
Studies examining milk’s impact on tea’s health effects have shown mixed but notable findings:
- Absorption Inhibition: Research from the European Heart Journal demonstrated that adding milk to tea could reduce its beneficial effects on blood vessels by lowering the bioavailability of catechins, which help prevent blood vessel constriction.
- Reduced Heart Health Benefits: Other studies, such as one conducted in 2007 in Germany, found that black tea improved arterial function in participants – but only for those who drank it without milk. Participants who added milk saw no arterial benefit.
- Conflicting Evidence: Some studies suggest that while the protein and antioxidant bond can reduce bioavailability, the extent may vary depending on the type of tea, milk, and other factors.
Could Alternatives to Dairy Change the Outcome?
For those who prefer their tea creamy, plant-based milks may offer an alternative that won’t disrupt tea’s antioxidant benefits.
- almond
- oat
- soy milk
contain different proteins that may not bind with polyphenols in the same way caseins do. While studies are still limited on the impact of plant-based milks on tea’s antioxidant properties, some research suggests that these milk alternatives do not have the same binding effects as dairy, allowing antioxidants to work as intended.
Tips for Maximizing Tea’s Stroke-Preventing Benefits
- Drink Tea Plain: Enjoying tea without milk or other additions is the most effective way to maximize its antioxidant potential.
- Consider Green Tea: Green tea is particularly high in catechins, so drinking it plain may be an especially beneficial way to lower your stroke risk.
- Try Plant-Based Milks: If you like milk in your tea, experiment with plant-based options, which may have a lesser impact on antioxidant absorption.
- Add Lemon Instead: Adding lemon to tea may enhance catechin absorption without any adverse interactions. Citrus helps preserve and increase the bioavailability of antioxidants.

Milk in tea may alter the bioavailability of its stroke-preventing antioxidants, but the effects can vary based on factors like the amount of milk and type of tea. To get the most health benefits, drinking tea plain or experimenting with plant-based milk alternatives could help preserve tea’s protective qualities.
