Lutein and zeaxanthin are carotenoid pigments primarily sourced from marigold flowers and are known for their role in eye health, specifically protecting the macula from age-related damage and potentially slowing the progression of AMD and cataracts. They act as antioxidants and filter harmful blue light. While generally considered safe, high doses may lead to carotenodermia, and some individuals might experience mild gastrointestinal upset. Emerging research suggests potential benefits for skin health as well.
Key Information
Inside Body Harmful Score
Common Dosage
10-20mg daily
Source Type
natural
Production Process
Lutein and zeaxanthin for supplementation are primarily extracted from marigold flowers (Tagetes erecta). The extraction process involves solvent extraction, followed by purification and crystallization to obtain the desired carotenoids.

Inside BodyPotential Benefits
Promotes healthy skin and reduces signs of aging.
Enhances and maintains optimal eye function and health by supporting clear vision, reducing the risk of age-related eye diseases, and protecting against environmental stressors. Benefits may extend to improved night vision and reduced eye strain.
Lutein and zeaxanthin protect the macula from oxidative damage and blue light, potentially reducing the risk of AMD progression and improving visual function in some individuals with existing AMD.
Lutein and zeaxanthin, acting as antioxidants, may protect the eye's lens from oxidative damage and filter blue light, potentially lowering the risk of cataracts. Higher intake through diet or supplements is suggested to increase their concentration in the eye.
Possible Side Effects
May cause mild digestive discomfort.
Digestive upset includes various gastrointestinal symptoms like nausea, diarrhea, and abdominal pain, stemming from factors such as medication, diet, or infections. The severity and duration vary depending on the cause and individual sensitivity.
Skin yellowing, or jaundice, results from elevated bilirubin levels, causing a yellowish discoloration of the skin and eyes. It can indicate underlying conditions like liver disease or hemolytic anemia and requires medical evaluation.
Skin may turn yellow at high doses due to zeaxanthin accumulation.
Scientific Evidence
AREDS2 study (Age-Related Eye Disease Study 2); Numerous studies on macular pigment optical density (MPOD) and AMD risk reduction; Limited studies on skin health benefits related to UV protection and antioxidant activity.
