How often should I take EXhale®?

For those with unhealthy lungs, we recommend taking EXhale® on a daily basis (10mL per day). Note that in times of stress, two 10mL doses per day can be taken, provided that people don’t exceed the following:

  • The daily recommended maximum dose of quercetin, which is 1,200mg (note there is 500mg of quercetin in one dose of EXhale®, but there are other supplements and medicines which may contain quercetin);
  • The daily recommended maximum dose of zinc, which is 50mg (note there is 15mg of zinc in one dose of EXhale®, but there are other supplements and medicines which may contain zinc).

For those with healthy lungs, we recommended taking EXhale® as needed – in times of environmental stress or illness (10-20mL per day).


What ingredients are in EXhale® and are they natural?

The bioactive ingredients in EXhale® are natural and are sourced from New Zealand and imported (where not grown in New Zealand). The bioactive ingredients are:

  • Anthocyanins – a boysenberry and blackcurrant extract, with immune boosting properties and lung health properties;
  • Quercetin – a plant flavonol, with immunity properties, extracted from buds of the Japonica saphora tree, acts as a zinc ionophore which means it helps zinc cross cell membranes;
  • Chelated zinc – a form of zinc in its most bioavailable form;
  • Mānuka honey (UMF 20+) – oral immunity properties and acts as a carrier for quercetin to support absorption.
