Description of intervention(s) / exposure
A. Standard FloraGLO Lutein 20mg / day – Proprietary Ingredient ID 12948
B. AquaCelle FloraGLO Lutein 5mg / day – ARTG L 277981
Randomisation 1:1

The investigational products are to be taken at breakfast time with water.

Approximately 62 adult male and female participants aged between 20 and 45 years will be recruited from
databases and public media outlets. Following preliminary screening via telephone, if eligible, potential participants
will attend the clinic for an information session and will be requested to provide their consent for inclusion in the
trial. Consenting potential participants will undergo a health assessment including lifestyle, current medications,
weight and height assessment and medical history; this data will be used for the comprehensive screening and to
provide contextual data for the study. Blood lutein concentration will also be measured.
Participants will be given a list of foods to avoid during the study period. Participants will also
complete a food diary at baseline, week 8 and 16.
The specific foods participants must avoid during the study are:
• Spinach, kale, chard, collard greens, mustard greens, lettuce, spring onions, broccoli
• Coriander, basil, parsley
• Pistachio nuts
• More than 3 eggs per week
Participants will take the allocated product daily for 16 weeks and undertaken the same baseline
measures at weeks 4, 8, 12 and 16.
Macular Pigment Optical Density (MPOD) will be measured by the MPS II Macular Pigment Screener
(Elecktron Technology) (MPS II). MPS II is a computerised instrument for measuring MPOD. The
MPS II emits low intensity light of specific wavelengths at calibrated intensities. The test subject is
asked to look into the instrument at the stimulus light and asked to press a button when a light flicker
appears.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The potential participants are screened by the investigator for inclusion in the study. The eligible participants are enrolled by investigator and provided with a "Numbered Container" that is identical to all other containers and contains the same information on the label, except for the number. The investigator is blinded to the product randomized with the
numbered containers labelled prior to delivery to investigational site. Product allocated as participants are enrolled in sequential order
