Summary

The aim of this study is to investigate in healthy adults, 18-40 years of age, how the absorption of 5 mg of L differs between consumption as a supplement, blended foods, and whole food equivalent of blended foods.

Detailed description

The absorption the macular carotenoids has shown variability between different supplements, and food sources such as egg and spinach. Investigation of the absorption of different forms of food (e.g. cooked, raw, blended) is not as well studied. Investigating the absorption of lutein from different forms of food is important to be able to prescribe lutein from forms of food that will be optimally absorbed.
