Evaluation of Changes in Skin Carotenoid Scores in Medical Students Following a Dietary Supplement-based Intervention

Completed · Not applicable

Conditions studied: Health Behavior

In brief

Skin Carotenoid Scores (SCS) are a biomarker of overall antioxidant status. This study extends an earlier study in which an increase in skin carotenoid scores (SCS) was observed in subjects who increased their intake of fruits and vegetables. The scores were determined using the Raman Spectroscopy. In that study subjects were assigned to one of four groups based on their baseline SCS. For unknown reasons, the groups with the highest and lowest baseline SCS failed to show an increase whereas the two intermediate groups did. One possible explanation might be that intakes varied more than expected and was not obvious due to self-reporting of intake of fruits and vegetables with different contents.

You may qualify if…

• Medical students must be willing to maintain the increased consumption of dietary supplements, two twin-sachet packets of seven (7) supplements twice per day, for the entire eight-week experimental period, to maintain the logs and to report at each of the times that measurements will be made. Individuals taking non-Pharmanex dietary supplements e.g. vitamins, minerals, herbals, and/or antioxidants will be asked to discontinue use at the time of the consenting to the study. Study supplements will replace all previous dietary supplements.
• BMI between 20 and 29.9
• Non-smoker, non-pregnant, non-lactating
• No use of tanning beds or sunless tanning products during the study

You may not qualify if…

• Prior participation in the previous study (L14 -128)
• Individuals suffering from any chronic illness requiring ongoing medication, such as diabetes, hypertension, heart disease, GI disorders or other metabolic disorders
• Individuals allergic or intolerant to shellfish,
• pregnant or lactating women,
• smokers
• individuals with BMI > 30
• Prior ingestion of LifePak Nano or other Pharmanex dietary supplements within the past 3 months.
