Breathe deeply: Research finds you can absorb nutrients and vitamins from fresh air
The idea that humans can absorb nutrients and vitamins directly from fresh air through breathing is not supported by established scientific evidence. While fresh air has many benefits—such as improved oxygenation, reduced stress, and better mental clarity—it cannot serve as a source of nutrients like vitamins and minerals, which are obtained through diet.
Why can’t nutrients be absorbed from air?
Nutrients like vitamins, proteins, and minerals are large, complex molecules that cannot be absorbed through the lungs.
The respiratory system is designed for gas exchange (oxygen and carbon dioxide) and does not have the mechanisms needed to process or transport nutritional molecules.
Nutrients require digestion and absorption through the gastrointestinal tract, a process the lungs are not equipped for.
Fresh air’s actual benefits:
Oxygenation: Fresh air supplies oxygen, which is vital for cellular function and energy production.
Mental health: Time in natural environments reduces stress and promotes relaxation.
Improved air quality: Cleaner air supports respiratory health by reducing exposure to pollutants.
