There is little difference between tap water and bottled water. According to the U.S. National Library of Medicine, bottled water tastes somewhat better to some folks, but has a history of incidents with water quality. In fact, most bottled water is just tap water, perhaps filtered by some companies, but often not. However, oxygenated water is a different story: It is in no way the same as tap water.


Some bottled water has added oxygen in it, called oxygenated water. These bottles are free of typical chemicals, pollutants, and other contaminants found in tap and straight bottled water. They contain pure water and oxygen: That is it. An oxygen-rich environment starves harmful pathogens, ultimately killing them. What is more, oxygen has a horde of notable health benefits that tap water does not.


Compared with ordinary tap water and most bottled water, oxygenated water is much richer in oxygen, containing significantly higher levels of it. Companies use a multistage process to make it, first filtering out impurities to purify the water, and then charging it with active oxygen. Unlike oxygen-starved tap water, oxygen mixes well with pure water, giving it several advantages over chemical-laden tap water:


Oxygen is vital for a healthy immune system. It acts as a natural immune booster, supporting it where necessary so that it can fight disease effectively by itself. Tap water contains an abundance of harmful pathogens, which, according to the U.S. National Library of Medicine, cannot survive in oxygen-rich water. This protects you from infection and disease and prevents sick-causing inflammatory response.


The digestive system needs good bacteria to help break food down. Tap water only suppresses it. Since good bacterium thrive in oxygen-rich conditions, oxygenated water is crucial to promoting digestion. This is especially important for cancer patients, or those suffering other digestive issues, such as irritable bowel syndrome, or any of the conditions that make absorbing much-needed nutrients difficult.


Cellular respiration is the process of cells obtaining energy from the food you consume, whether anaerobically or aerobically. Aerobic respiration occurs when oxygen is present, but with no oxygen, such as tap water, it is anaerobic. The U.S. National Library of Medicine explains that aerobic respiration is more efficient than anaerobic, so drinking oxygen bottled water is wiser than drinking tap water.


When the body accumulates too much lactic acid, you end up with painful lactic acidosis. This is the result of anaerobic respiration, and it occurs with heavy exercise, typically when oxygen levels in the body decline. Muscles need more oxygen during exercise than what the blood can reasonably supply, which is why it turns to oxygen-less anaerobic respiration to get the energy that muscles require.

Although efficient at meeting its energy needs, anaerobic respiration has consequences. It forms lactic acidosis as a byproduct, which can be especially nasty if you have to compete, perform physically, or have other jobs to do. Lactic acidosis causes pain, fatigue, and it takes longer to recover afterward. Oxygenated water provides sufficient oxygen to keep cellular respiration aerobic, so no lactic acid.


The more oxygen your blood has, the better you will feel: Energetic, alert, more awake. This state of energy lasts longer too when more oxygen circulates the blood. Drinking oxygen bottled water increases oxygen levels in the blood, which is not true of plain tap water. Oxygenated water sends more oxygen to your cells, tissues, muscles, brain, and other organs, improving stamina and overall health and wellness.


Having the right pH is essential for good health. Eating unhealthy food lowers the body’s pH balance, resulting in an acidic environment where harmful bacteria can and do thrive. Good food increases alkalinity, balancing acidity out. Tap water does nothing for the body’s pH, but oxygenated water is alkaline. For this reason, oxygen is the most natural supplement for maintaining an ideal pH range.


An oxygen-low environment creates ideal conditions for metastasis of cancer cells, where they multiply and spread. However, oxygen creates alkalinity, so drinking oxygen bottled water increases oxygen at the cellular level, ultimately preventing metastasis, starving existing cancer cells, and preventing cancer development too. Tap water, with its many dangerous contaminants, might actually cause cancer.


Tap water is not particularly good for you. Bottled water proves not much better. Oxygenated water, however, promises more health benefits than anyone with sense can refuse, and it contains no chlorine, fluoride, fungi, bacteria, and other dangers either. As scientists discover more about the effects of an oxygen-rich environment for the body, the popularity of oxygen bottled water is set to skyrocket.
