Boost Oxygen Supplemental Oxygen to Go | All-Natural Respiratory Support for Health, Wellness, Performance, Recovery and Altitude (10 Liter Canister, 5 Pack, Natural)

Excellent

I can't really tell much if any benefit.

Great product, works fast. I use this while working out and it REALLY helps giving some boost to my cells. When I start breathing hard, I use this for about 1 mins and it helps power me up. The #1 problem I have with this product is their PRICE. These need to be 1/2 the cost. It can be that expensive to make this oxygen in a can.

Unfortunately, I have a severe case of COPD from smoking too much for too long. I have an oxygen machine with a very long tube for around the house but if I walk to briskly I find my oxygen level down to the low 80's (using an oximeter). Using a can of Boost Oxygen, within 30 to 45 seconds, my oxygen lever rises to the low 90's. I let my oxygen hookup take it the rest of the way. I tried another brand of canned oxygen that claimed 99% oxygen. I took a brand new can of it to a doctors appointment and as I was slowly walking up the walkway, my oxygen level took a dive to the low 80's. I had one of the new cans in my hand and when I used it, it felt like it was just plain air (oxygen dipped down to 80). My wife ran back to the car and brought me a half used can of boost. It took a couple of minutes but I got my O2 level back up to the mid/high 90's. I sent the other brand back to the supplier for which they charged me a 20% restock fee. Over the past 12 months, I have purchased at least 10 to 12 orders (5 or 6 cans each from Amazon) of Boost Oxygen and never go anywhere without a 10 liter can of Boost.

This is well worth it. If you’re feeling tired or fatigued, a couple of breath of this stuff will get you right back on track! I would get the large bottles not the small ones.
