Tag: Polyphenol supplements

While diets rich in plant-based foods have been consistently linked to better health outcomes, this is not true for all plant compounds. High-dose supplements containing concentrated plant compounds, including polyphenols, can lead to adverse health effects. This raises the important question: Can you get too many polyphenols?

According to research, polyphenols from whole foods are generally safe for most people, but the concentrated, high doses found in supplements can lead to potential adverse health effects. This raises the important question: Can you consume too much polyphenols, and what are the risks involved?

While widely celebrated for their powerful antioxidant properties, excessive consumption of polyphenols, particularly from high-dose supplements, can have adverse health effects, including impaired nutrient absorption and liver damage. The risks are generally not associated with consuming polyphenol-rich whole foods.

An estimated 25% of the global population is affected by iron deficiency, a condition that can be worsened by high polyphenol intake. While generally safe in dietary amounts, certain individuals and medical conditions restrict or advise caution when consuming polyphenols, particularly in concentrated supplement form.
