However, keep in mind that no supplement is intended to treat, cure, or prevent disease.

Improved Energy Levels

Yerba mate contains caffeine, which stimulates the central nervous system.

This may help to improve mental and physicalfatigue, alertness, reaction time, and concentration.

Those who consumed the yerba mate reported improved focus, energy, and concentration.

However, research hasn’t confirmed this benefit.

Protects Heart Health

Growing evidence suggests that yerba mate may help reduce the risk of heart problems.

The study included participants both with and withouthigh cholesterol.

Greater effects were seen in those with high cholesterol levels.

Researchers believe these benefits are due to yerba mate’s high polyphenol content, including chlorogenic acids andquercetin.

However, the sample sizes of participants in this study were small.

Further research is needed to confirm these findings.

Significant performance improvements were also observed during high-intensity exercise.

Nonalcoholic fatty liver disease (NAFLD) is now known asmetabolic dysfunction-associated steatotic liver disease(MASLD).

Reduce Inflammation

Several animal studies suggest yerba mate has potent anti-inflammatory effects.

However, it’s important to highlight that most studies of anti-inflammatory benefits have been conducted in animals.

It remains unknown what the effects would be in humans.

Further high-quality studies are needed to determine yerba mate’s effectiveness in reducing inflammation.

When purchasing yerba mate, carefully read the product label.

Look for products that include only pure, organic yerba mate without other herbs or unnecessary additives.

Be cautious of prepared tea drinks, which tend to contain high amounts of added sugars.

Too much added sugar in your diet may lead to weight gain and chronic health conditions.

Additionally, it’s important to consider the caffeine content in yerba mate.

To prevent any potentially dangerous side effects, keep your daily caffeine intake below 400 mg per day.
