The Claim
Some people think that zeaxanthin's health benefits are restricted solely to eye health and that it has no other roles in the body.
Origin
This belief may come from the heavy focus on zeaxanthin in eye health supplements and related marketing materials.
What Science Says
While zeaxanthin is most known for its benefits to eye health, research suggests it also has antioxidant properties that may be beneficial for overall health. Studies have shown potential anti-inflammatory effects and possible roles in skin health and cognitive function, although these areas are less studied compared to ocular health.
Verdict
Misleading
