Drinking water from a copper glass routinely can boost your antioxidants and, therefore, boost your immune system. And because copper helps eliminate harmful bacteria, your immune system doesn't have to work as hard which will also keep you healthy. Copper strengthens your immune system. Copper helps stimulate peristalsis, the contraction, and relaxation of stomach muscles, which moves waste products (feces) through the intestines and out of the body. Copper also helps kill harmful inflammation-causing bacteria in the gut, possibly improving ulcers, indigestion, and infections.

Drinking water from copper glass can lead to the proponents claiming that copper water offers multiple benefits, including better heart and brain health, a more robust immune system, and even weight loss, anti-aging, and tanning effects. However, it's unlikely that copper water provides these health effects. Copper helps make an important enzyme in the body called adenosine triphosphate (ATP). ATP is energy. When you drink water from a copper cup, you are providing the copper needed for your body to make more energy.
