Nutrition Assessment

antioxidant, carotenoid
Brief summary
The goal of this clinical trial is to evaluate a nutritional supplement in an otherwise healthy adult population. The main questions it aims to answer are: * Do antioxidant carotenoid levels increase in after supplementation as measured by a non-invasive device? * Do wellness factors correlate with supplementation? Researchers will compare the nutritional supplement arm to a placebo group to assess its effects. Participants will take either the nutritional supplement or placebo once daily for 8 weeks. Participants will be scanned by a non-invasive hyperspectral absorption device to obtain a skin carotenoid score. Participants will also have facial images taken, dermal spectrophotometry measurements of their face, and complete self-assessment questionnaires.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Skin carotenoid score via Prysm iO device | 8 weeks | The Prysm iO device will provide a numerical score between 0-1000. The score is an indicator of skin carotenoid concentration/nutritional wellness. The higher the score the more positive the outcome. |
| Short-Form 36 Health Survey | 8 weeks | The Short-Form 36 Health Survey is a validated questionnaire that measures multidimensional health-related quality of life, including specific domains of everyday life. The questionnaire has a 1-5 scale, with the higher score reflected a better perception of health-related outcomes. |
| Skin color measurement via Spectrophotometer | 8 weeks | — |
| Perceived Immunity | 8 weeks | Perceived Immunity Scale, a validated questionnaire to assess individuals' beliefs about the strength of their immune system. The assessment uses a 1-6 point Likert scale, where a lower score indicates greater disagreement with the statement, and a higher score indicates greater agreement with the statement. |
| Psychological Scales Related to Physical Condition | 8 weeks | Short Health Anxiety Inventory (SHAI) a validated questionnaires using a 1-5 point Likert scale, (where a lower score indicates greater disagreement, and higher score indicates greater agreement) to assess feelings about health and recovery. |
| Fatigue and Vitality Status Assessment | 8 weeks | Multi-Dimensional Fatigue Inventory--a validated questionnaire using a 1-7 Likert scale (where a lower score indicates greater disagreement, and a higher score indicates greater agreement) to assess an individual's fatigue state. |
| Brief Resilience Scale (BRS) | 8 weeks | The Brief Resilience Scale (BRS) is a validated questionnaire, using a 1-5 point Likert scale (where a lower score indicates greater disagreement, and a higher score indicates greater agreement), to assess the ability to bounce back from feelings of stress. |
