BACKGROUND: Carotenoids have health benefits for skin (beta‐carotene), prostate (lycopene), and eye (lutein). Various techniques are used to assess antioxidant levels. OBJECTIVE: We used three techniques to measure antioxidant status following dietary carotenoid supplementation; Total Antioxidant Function (Spectracell SpectroxTM); Lymphocyte Proliferation Index (Spectracell ImmunidexTM); and Reflectance Spectroscopy (MonaVie ViewTM). METHODS: Thirty‐nine healthy volunteers were supplemented daily with a carotenoid blend (60% beta‐carotene, 27% lycopene, 13% lutein) at 5mg (Low, N=11), 7.5mg (Med, N=8), 30mg (High, N=11), or 0mg (Control, N=9). Blood samples (Spectrox/Immunidex) and skin reflectance scores (View) were taken at Baseline and Week 8. RESULTS: Control subjects showed no significant change in any measure. Post‐supplementation, skin reflectance scores (View) were higher in all three groups; Low (+24%); Med (+89%); and High (+136%); total antioxidant function (Spectrox) was higher post‐supplementation in Low (+22%), but not in Med or High; and lymphocyte proliferation (Immunidex) was higher in Low (+10%) and Med (+12%), but not High. CONCLUSION: These results suggest differential responses of antioxidant assessment techniques and indicate the need for further research on the relationship between antioxidant intake, assessment technique, and health effects.
