Yerbador Mate Blog

The same email keeps coming back to our customer service every so often, especially in autumn, when the days get shorter and the topic of vitamin D returns to the media: “I drink yerba every day, will it help with my D deficiency?” We answer just as honestly as with every other ingredient in this…

This question comes up regularly in messages to our customer service: since yerba mate is dried leaves, dark green and full of chlorophyll, maybe it also contains a lot of vitamin A? We’re checking this just as honestly as with every other ingredient in this series — without bending the conclusion to fit a marketing…

After vitamin C and vitamin K in this series, it’s time for the B group. This is an interesting topic because the mechanism is different than with the previous two. Vitamin C in yerba mate largely breaks down during drying and brewing, vitamin K stays trapped in the leaf because it’s fat-soluble, not water-soluble. B…

Vitamin K had its episode in this series, now it’s vitamin C’s turn – because this is a topic surrounded by quite a few oversimplifications. Some descriptions of dried yerba leaves, including our own description of the Immuno product, list vitamin C among the components of yerba mate leaves. A question worth asking honestly: does…

Yerba mate and selenium is the last missing piece of our series on minerals in the leaf of the Paraguayan holly – we’ve previously covered potassium, calcium, magnesium, zinc, sodium, phosphorus, iodine, iron, copper and manganese in a similar way.

Yerba mate and manganese is the last question in this series about minerals in the yerba mate leaf – earlier we broke down copper, zinc, iodine and sodium in a similar way. The rule is the same: we check what is really known about manganese content in the dried leaf and the infusion, what this…

Yerba mate and copper is a question from the same family as questions about zinc, iodine or sodium that we’ve already covered in this series – someone is looking for yet another mineral in the leaf of Paraguayan holly before checking their plate. We answer just as honestly: how much copper is really in the…

We mainly hear from two groups of people. The first has been drinking yerba for years and simply wants to know if the timing matters before heading to the gym. The second is just switching from coffee and asks directly: can this replace a pre-workout? The answer doesn’t fit in one sentence, but let’s start…

How many calories does yerba mate have? This question comes up often when someone swaps their morning coffee for a matero, or is looking for a drink that gives energy without weighing down their daily calorie balance. The answer is simpler than most discussions about this plant suggest: the infusion made from dried Yerba Mate…
