Will drinking Mateína break a fast?Updated 4 hours ago

No—our Mateína Zero Sugar won’t break a fast.

Here’s why:

It contains virtually no calories (about 20 cal per 355 mL can) and zero sugar—well below the typical fasting threshold of ~50 cal.

Yerba mate itself, when unsweetened, is generally considered acceptable during fasting due to its minimal calorie content.

Plus, it may even help curb appetite and support steady energy throughout your fasting window.

That said, fasting goals can vary from person to person, so what breaks a fast may depend on your specific approach or reason for fasting.
