How does Mate work?

Mate contains caffeine and other chemicals which stimulate the brain, heart, muscles lining blood vessels, and other parts of the body.

Are there safety concerns?

Mate might be safe for most people, when taken for short periods of time. It contains caffeine, which can cause some side effects such as inability to sleep (insomnia), nervousness and restlessness, stomach upset, nausea and vomiting, increased heart rate and breathing, high blood pressure, headache, ringing in the ears, irregular heartbeats, and other side effects.

When taken in large amounts or for long periods of time, mate might be unsafe. It increases the risk of mouth, esophageal, laryngeal, kidney, bladder, and lung cancer. Concurrent smoking and alcohol consumption compounds the risk.

Do not take mate if:
  • You are pregnant or breast-feeding.
  • You have a heart condition.
  • You have high blood pressure (hypertension).
  • You smoke.
  • You are a heavy alcohol user.
  • You have anxiety.
  • You have an eye disease called glaucoma.
  • You have osteoporosis.
  • You have a bleeding condition.
