A 2023 review in *Molecules* highlighted that while polyphenols have beneficial effects at lower dietary doses, they can also exert harmful effects depending on the dosage. Understanding the potential disadvantages of polyphenols is crucial, particularly when considering supplements or for individuals with pre-existing health conditions.

While adequate dietary intake of vitamin E, including alpha-tocopherol, is generally considered safe, some studies have linked high-dose supplements (400 IU or more) to increased health risks for certain populations.
