Eksperimentel: Suboptimal Qualia Vitamin C+
Participants with suboptimal vitamin C blood levels (0.4 - 0.9 mg/dL) taking two capsules of Qualia Vitamin C+ once daily in the morning, with or without food, for 28 days.
38 participants.
|
A novel multi-ingredient formulation delivering 500 mg total vitamin C per daily serving (2 capsules).
It contains a blend of Vitamin C (from liposomal vitamin C, mineral ascorbates, and fruit extracts), bioflavonoids, and ferulic acid.
Participants take two capsules daily in the morning, with or without food, for 28 consecutive days.

Placebo komparator: Suboptimal Placebo
Participants with suboptimal vitamin C blood levels (0.4 - 0.9 mg/dL) taking two capsules of placebo (inert rice powder in a vegetable/cellulose capsule) once daily in the morning, with or without food, for 28 days.
38 participants.

Change in blood Vitamin C levels in the suboptimal stratum
Tidsramme: Baseline to Day 28
|
To assess between-group differences in the change in blood Vitamin C levels in the suboptimal stratum from baseline to Day 28 following supplementation with Qualia Vitamin C+ versus placebo.
Assessed via Ulta Labs Vitamin C Test (lab blood collection).

FACIT-Fatigue Scale
Tidsramme: Baseline to Day 28
|
To assess within-group and between-group differences in the FACIT-Fatigue Scale in both the sub-optimal vitamin C stratum and the entire cohort.
Final score ranges from 0 to 52, where higher scores indicate less fatigue and better quality of life.

RAND-36
Tidsramme: Baseline to Day 28
|
To assess within-group and between-group differences in the RAND-36 (primary attention to the Vitality, General Health Perceptions, and Physical Functioning subscales) in both the sub-optimal vitamin C stratum and the entire cohort.
Each domain is scored on a 0-100 scale, with higher scores indicating better health.

Single-item Assessment of Immune Fitness
Tidsramme: Baseline to Day 28
|
To assess within-group and between-group differences in the Single-item Assessment of Immune Fitness in both the sub-optimal vitamin C stratum and the entire cohort.
A single numerical score between 0 and 10 is produced, with higher scores indicating better self-rated immune fitness.
