Bests & Worsts Reviews from Amazon

Please, I beg of you, save your money and do not buy this. This is the 21st century of snake oil that is playing on the fad of oxygen in everything in the health community. But don't take my word for it. Let me explain why this is a scam. The packaging advertises that it is "diatomic oxygen stabilized in water." At the simplest level, this just means it is pure oxygen dissolved in water. Assuming that this is strictly distilled water, and optimal conditions of storage (let's say 25 celcius as a nice number). At this temperature, only 40mg per liter of water is present in the "solution" that you are buying in this bottle. Given the fact that there is 4 fl oz in the bottle, and there are 118 ml in 4 fl oz, this gives us an amount of oxygen in the bottle of roughly 4.72 mg of pure oxygen in this 20 dollar bottle of "solution". Using the ideal gas law (PV=nRT), this gives (.2 * V ) = (.40 g / (32 amu [molecular weight of diatomic oxygen]) * 0.08206 * (273+25), this gives a total volume of oxygen contained in 1.52 liters of air. Given that the average tidal volume (volume of air consumed at rest) is around .5 L, this means that roughly three breaths would be needed at rest in order to make up for all of the oxygen that is contained in this bottle. This means that in the time of reading this review, assuming that your breathing rate was around 20 bpm, you would have consumed roughly seven times more oxygen than what is contained in this 20 dollar bottle in one minute. This in turn means that you are changing the equivalent of 120 dollars for the equivalent of one minute of resting breathing worth of air. I know this falls under the category of free market capitalism, but amazon should really remove these items as fraud. Considering that pure O2 inhalers for roughly 80L of pure O2 are available for 12 dollars, please buy those if you are trying to buy oxygen. Remember though, oxygen has not been shown to have any benefits in high intakes, and can actually issues as oxygen toxicity is an issue, although not at these relatively low doses. So whatever you do, please don't buy this product. It is literally just water unless they engineered some polymer structure to encapsulate oxygen, which is obvious not mentioned. Source: standard values were taken from first results on google, math taken from intro to chemistry class, other knowledge taken from my background in the medical field. I know this isn't proper citations, but for an amazon review, this should be good enough. If you wish to learn the chemistry and check my math, by all means do so, but I don't think for most this will be necessary.
