Oxygen capsules are small, portable containers filled with concentrated oxygen. They are designed to provide supplemental oxygen to individuals who may need it for various reasons, such as during physical exertion or at high altitudes. These capsules can help improve oxygen levels in the body, enhancing overall performance and reducing fatigue. Typically, oxygen capsules are used by athletes, travelers, and people with respiratory conditions. They are easy to carry and can be inhaled directly or used with a delivery device. The use of oxygen capsules can support better breathing and increase energy levels in challenging environments.
