Summary

This study tests whether a daily vitamin C supplement called Qualia Vitamin C+ can raise blood vitamin C levels in healthy adults aged 25 to 75 who have either low or normal vitamin C levels. Participants take two capsules daily for 28 days and provide blood samples to measure changes. The trial also looks at effects on fatigue, quality of life, and immune fitness through online questionnaires.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Qualia Vitamin C+ (a blend of vitamin C, bioflavonoids, and ferulic acid)
What this could lead to
If it works, this could show that a specific supplement formulation effectively boosts vitamin C levels in people with low or normal levels.
What could go wrong
This is a small, short-term study in healthy adults, so results may not apply to broader populations or long-term health outcomes.
