Set up Profile nowThe Powerbreathe Plus is a handheld inspiratory muscle training (IMT) device. It works by adding calibrated resistance to your inhalation, progressively strengthening the diaphragm and accessory breathing muscles in much the same way resistance training strengthens skeletal muscle. Stronger respiratory muscles reduce the perceived effort of breathing during exercise, and may support oxygen delivery efficiency during sustained physical or cognitive demands.
It suits a wide range of users: endurance athletes looking to delay respiratory fatigue in heavy training blocks, individuals recovering from illness that has left breathing feeling laboured, or anyone who notices that poor breath control is affecting focus or stress levels during the day. Because the cognition pillar recognises that cerebral oxygen supply and autonomic regulation both hinge on breathing quality, this device has a place beyond sport.
IMT is one of the better-evidenced non-pharmacological tools in respiratory physiology. The research base covers healthy athletes, clinical populations, and desk-based adults alike. The Powerbreathe Plus is a mechanical device — not a supplement — so there are no ingredient interactions to consider, making it accessible to nearly everyone. Consistent daily practice, typically a short set of breaths once or twice per day, is where the benefit accumulates. Results are gradual but measurable: many users notice reduced breathlessness within a few weeks of regular use.

Follow the specific resistance and repetition guidance included with the device. Most IMT protocols involve one or two short sessions daily, performed consistently over several weeks to accumulate benefit. Check the packaging and instructions for your starting resistance level.
It is a physical handheld device, not a supplement. It trains your breathing muscles through calibrated inhalation resistance, so there are no ingredients, no doses, and no interaction risks with medications or other supplements.
Most people using IMT consistently report a reduction in breathlessness and an improvement in breathing effort within four to six weeks, though this varies with baseline fitness and adherence. Benefit accumulates with regular daily practice rather than occasional use.
Endurance athletes in heavy training, people recovering from respiratory illness, and individuals who experience shallow breathing under stress or during focused cognitive work are the most likely to notice a meaningful improvement.
Because it places resistance on inhalation, anyone with a diagnosed respiratory condition — such as asthma, COPD, or a recent chest infection — should check with their GP or respiratory clinician before starting an IMT programme.
Most protocols call for a short session — typically a set number of breaths — once or twice daily. It requires no warm-up, no equipment beyond the device, and can be done seated at a desk or before exercise. Refer to the included instructions for the recommended starting protocol.

Gentle on a sensitive stomach, and I feel like myself again. I had tried two other glandulars before this and neither sat right.

I was sceptical about glandulars, but my mid-afternoon crash has genuinely eased. One capsule with breakfast and I forget about it.

Not a stimulant, which is exactly what I wanted. It took about ten days, then I realised I wasn’t dreading the afternoon any more.

Bought after a blood panel flagged a flat cortisol curve. Easy to take, no jitters, and the sourcing is refreshingly transparent.

Training hard through a stressful stretch and this has helped me bounce back between sessions. Already on my second bottle.

No frills, one ingredient, a sensible dose. I appreciate that it is designed to be used for a season rather than forever.
