What Happens to Your Iron Levels When You Drink Too Much Matcha?

Matcha is a nutritious, delightful drink that can boost energy, reduce stress, and improve attention. It also contains a unique blend of caffeine and L-theanine, a naturally occurring amino acid, making it a milder alternative to coffee. While the tannins and other components in matcha may prevent certain people from absorbing iron, this is usually not a big deal for the average person.

People who are at a higher risk of iron deficiency, such as those who are menstruating, pregnant, or follow a vegan/vegetarian diet, should be particularly aware of matcha’s effects on iron. According to Yoshua Quinones, MD, consuming more than one cup of matcha per day or with meals might prevent the body from absorbing iron, and the caffeine can build up to a dangerous level. Inquire about testing options with your provider if you are uncertain about the possibility of low iron levels. Read the article for more information.
