MetaBuz™ is sold as a turmeric chai tea, and one of the ingredients is Ceylon Cinnamon Verum (the superior cinnamon type, as opposed to its less expensive cousin, Cassia). We source high quality ingredients for MetaBuz™.
We do not comment on health matters, please seek advice from your health professionals.
What I can say, is that we have had few reported problems related to cinnamon in our products. Very few people are allergic to cinnamon but it does happen. I have thoroughly researched MetaBuz™. My family and I drink it regularly.
