What antioxidants do
Oxidation-reduction reactions are normal parts of biology. Antioxidant systems help manage reactive molecules, and the body uses both endogenous defenses and nutrients obtained from food.
Supplement trials can differ from food associations
People who eat diets rich in fruits and vegetables often have better health outcomes, but that does not mean isolated high-dose antioxidant supplements reproduce those outcomes. Clinical trials of specific antioxidant supplements have had mixed or context-dependent results.
Respiratory research needs disease-specific outcomes
Laboratory evidence of antioxidant activity is not enough to claim improved breathing, mucus clearance or treatment of a lung disease. Human clinical outcomes are the relevant standard for those claims.
What this means for evaluating Breathe
If an ingredient in Breathe has antioxidant properties, that can be described as biochemical background. It should not be converted into a claim that Breathe is clinically proven to improve respiratory disease.
