Protect your lungs from the smog.

The Air Quality Health Index has reached level 10+ in metro Vancouver today as a result of the smog from the wild fires. Breathing in too much of the smoke from the wild fires not only can cause acute respiratory distress in those with underlying conditions such as asthma and heart diseases, but can also affect our respiratory health in the long run. Other than staying indoor and avoiding strenuous outdoor activities, check out the following supplements that are excellent for supporting our lungs.

1. N-acetyl-cysteine (aka NAC): NAC is mucolytic meaning that it can break up mucus; therefore, it can help us reduce the production of mucus in our respiratory tract caused by the irritating smoke. It also supports our lungs by increasing the body’s level of glutathione which is the primary antioxidant for the lungs!

2. Glutathione: as mentioned above, glutathione is the major anti-oxidant found in lung tissues! It is also a critical player in our body’s detoxification system. Unfortunately, oral intake of glutathione is not recommended as the absorption is very low. The best way to boost your glutathione levels is via intravenous therapy or nebulized glutathione treatment.

3. Marshmallow Root (Althaea officinalis): Don’t confuse this ancient herb with the marshmallow that we use for our s’mores! Marshmallow root, Althaea officinalis, is an ancient herb that is known for its ability to soothe and moisten the mucous membranes of the respiratory system.

4. Vitamin C: Another great anti-oxidant for our lungs. It helps scavenge the excess free radicals in our body as a result of inhaling the polluted air. In addition, vitamin C also helps boost our immune system and is great for preventing colds and flus!

5. Essential Oil: Inhalation of essential oil like peppermint and eucalyptus are excellent for clearing congestion in the upper respiratory tract caused by irritants. They are also great natural air fresheners!
