Summary

This completed trial tested whether a daily supplement called Qualia Vitamin C+ can raise vitamin C levels in the blood. Thirty-six healthy adults aged 25 and older took either the supplement or a placebo for 28 days. Researchers measured blood vitamin C at the start and end, and also asked participants about their thinking, stress, and immune health. The study was done remotely, with blood draws at local labs.

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+ (dietary supplement)
What this could lead to
If it works, this could show that Qualia Vitamin C+ effectively raises blood vitamin C levels in healthy adults.
What could go wrong
This is a small, early-stage trial with only 36 participants, so results may not apply to everyone. The supplement may not significantly outperform placebo.
