Breathe Easy. Lung Health is Vital for Everything!!

Whether you are trying to improve your running times, wheezing from a cough/cold/bug, or dealing with allergies/asthma, we can all agree that being deprived of breath (poor oxygen delivery) is very stressful. As our bodies sound the alarm in response to oxygen deprivation, that stress can paradoxically make it even harder to catch our breath.

Oxygen delivery to your body is the lungs' job. But then there is the question of how well your body uses that oxygen once it arrives? In other words how efficiently are your cellular furnaces (the mitochondria) using that oxygen to produce energy? After all, if oxygen arrives in our tissues only to be poorly used once it gets there, it's not going to do a lot for making us feel or function better.

So how can you improve both oxygen delivery and utilization ...and in turn, your brain function, your muscle function, your immune system, your stress levels...and virtually every other aspect of health?

Though there could be many valid answers to this question, if I had to pick only one it would be getting the cells in my lungs, and other tissues, to produce optimal levels of GLUTATHIONE! This is something that will improve the health and function of every lung cell, and in every individual! In fact, your VO2 Max, an accepted measure of lung capacity, is a major predictor of longevity. [1]  


After helping people with their nutrition and supplements for over 30 years, if there was one substance I would recommend to promote optimal glutathione production, it would be NACET, the ethyl-esther of NAC, with up to 10X better efficiency than regular NAC. [2]  NACET is simply long chains of NAC molecules joined together, and you simply absorb it dramatically more effectively than other glutathione precursors.

NACET is the key ingredient in the product GSH+ Ultimate Glutathione. In fact, GSH+ is the only synergistic formula I know of that uses NACET.
Of course, there are also other things you can take to boost glutathione, and a great many of these can also be found in GSH+.

Because I am limited by Health Canada in "making claims" about this formula, (see Health Canada's accepted list of approved uses below), I will simply talk about my experience as a practitioner. 

Since starting to recommend GSH+, I have seen many benefits from it for immunity, detoxification, better brain-power, and overall well-being. But if I had to pick the most pronounced effect that I have seen, it is the ability of GSH+  to improve lung function. I am referring to recovery after illness and persistent coughs, improved breathing in asthma and allergies, (for example from pollen, smoke irritation, wildfires or otherwise), and last, but definitely not least, improvement of physical endurance.

For all you endurance athletes out there, a question: is it your lungs or muscles that give out first? Producing more glutathione inside your cells will help both!  (GSH+ is actually the favorite supplement of a long-distance runner who works in our office. See her comments below!)

Of course, not surprisingly, there is literature to support glutathione's impact on, and necessity for healthy lung function, particularly in offsetting the effects of inflammation....even from cigarette smoke (see #7).

Here's to better breathing!

Be well,



Kristine's Experience:
After attending a Training with John and hearing an in-depth description of how GSH+ supports optimal function of a number of systems within the body, I had to give it a try. As an assistant in Accounting by day, and a dedicated distance runner training for races in my free time, I'm always looking for a performance edge. I find that taking GSH+ on an empty stomach first thing in the morning gives me clarity and mental sharpness for work, and then taking GSH+ before my runs provides a noticeable bump in energy and stamina. It's as though everything just 'clicks'. If I could only choose one supplement to help me feel my best every day, it would be this one.
