Zeaxanthin 5%
Zeaxanthin 5% is a dietary supplement that contains the carotenoid zeaxanthin, which is an antioxidant found in various foods such as green leafy vegetables and eggs. Zeaxanthin is beneficial for eye health and can help delay and even prevent the progression of cataracts and age-related macular degeneration.
According to a study in rats, there were no adverse effects for lutein or zeaxanthin for daily doses of up to 1,81 mg per pound (400 mg/kg) of body weight, which suggests that it has a good safety profile. However, zeaxanthin is likely safe when used in doses up to 2 mg daily. It is possibly safe when taken in larger doses, and doses up to 10 mg daily seem to be safe when used for up to 1 year.
There is currently no recommended dietary intake for zeaxanthin, but research suggests that 10 mg of lutein and 2 mg of zeaxanthin appear to be effective in studies, although further research is needed to identify the optimal dosage for health. Zeaxanthin may also protect kidney health, maintain homeostasis in the body, and even become a therapeutic drug for liver disease.
There are no known case studies regarding the benefits of Zeaxanthin 5%, but there are several studies on the benefits of zeaxanthin as a dietary supplement. It is important to note that there may be some concerns about taking xanthophylls (which include zeaxanthin) at higher dosages, but more research is needed. It is recommended that individuals consult with their healthcare provider before taking any dietary supplements.
