Lutein is commonly sourced from the extract of marigold flowers. It is an antioxidant that absorbs blue light, acting much like a pair of internal sunglasses to help shield the eyes from light-induced damage. The human body cannot synthesize lutein on its own and must obtain it by consumption of vegetables and fruits. Thanks to technological advancement, individuals with busy lifestyles can now supplement lutein directly, making it a convenient nutritional choice.
Ester form: Lutein esters have a larger molecular mass and need to be hydrolyzed by enzymes before absorption. Lutein esters are recommended to be taken during or after meals for better absorption with the help of dietary fats.
Free form: Free-form lutein has a smaller molecular mass, does not require enzymatic hydrolysis, and can be absorbed and utilized directly by the body. This makes it a more convenient and efficient choice.
Regulatory Information – TFDA
According to regulations established by the Taiwan Food and Drug Administration (TFDA), the daily intake of lutein from a finished product should not exceed 30 mg.
Currently, purified lutein is also used as a food additive. Its use is regulated under limits that differ slightly from those for marigold flower extract. Careful use is warranted when using it in food products.
