Experimental: 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.
|
Contains inert rice powder in a vegetable/cellulose capsule.
Participants take two capsules daily in the morning, with or without food, for 28 consecutive days.

FACIT-Fatigue Scale
Zeitfenster: 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
Zeitfenster: 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.
