Yerba Mate is a traditional South American drink made from the dried leaves of Ilex paraguariensis, a species of holly native to the region.

The preparation of yerba mate involves steeping the dried leaves in hot water, much like tea.

Recommended brewing temperatures are lower than other teas, around 60 to 65 degrees Celcius.

Yerba mate has a distinctive flavor, often described as being somewhat similar to green tea but with a more herbal, grassy character.

It’s also well-known for its caffeine content.

The caffeine level is typically somewhere between that of tea and coffee, making it a popular choice for a stimulating drink.

However, if you are brewing yerba mate in a traditional gourd or container, the caffeine content will likely be much higher.

The number of times you refill your yerba mate cup with hot water will also impact the amount of caffeine you consume.

In addition to caffeine, yerba mate contains a number of vitamins, minerals, and antioxidants.

GLP-1

Glucagon-like peptide one (GLP-1) is a significant and recently discovered hormone made in both the gut and brain that plays a key role in controlling appetite and feeding behavior.

Notably, GLP-1 works as an appetite inhibitor, and its increased presence is seen to reduce the urge to eat.

GLP-1 can also be stimulated by specific foods and substances, with yerba mate tea being a notable example.

Some research suggests potential links between yerba mate and certain types of cancers, primarily associated with the smoked version of the tea, although these findings are inconclusive.

Note: Its recommended to avoid the smoked versions of yerba mate as they contain carcinogenic cancer-promoting compounds.

Dopamine

Caffeine, in most forms, naturally spikes an individual’s dopamine levels for a period of time.

It’s common to consume yerba mate or coffee before physical training, usually does in the early part of the day.

Yerba mate and some of its compounds can also help to preserve the survival of dopamine neurons in both the movement-related pathway and the motivation pathway.

If enjoyed earlier in the day (before 12-2 pm), it should not interfere with sleep, and be beneficial for workouts.

Its recommended to delay consuming caffeine until 90 minutes to two hours after waking.
