Copper Mug - 16 oz (100% solid copper)

100% COPPER--No nickel, no stainless steel! These copper mugs are the real deal. Note that copper is a soft metal. There may be some slight imperfections. Many ancient traditions recommend drinking water stored in a copper vessel to improve health. Copper is antimicrobial and studies have indeed found that leaving water in a copper vessel kills off bacteria. University of South Carolina researchers exploring the purifying power of copper also found that Antimicrobial copper surfaces in intensive care units (ICU) kill 97% of bacteria that can cause hospital-acquired infections, resulting in a 40% reduction in the risk of acquiring an infection. The research found that the rooms with copper-surfaced objects had less than half the infection incidence than those rooms without copper. Storing water in your copper water bottle is a great way to make natural alkaline water which tastes fresh, clean, and pure! However, copper can react with acidic fluids, (anything with a pH of less than 7) so we recommend using only water in your copper cup. Copper plays an important role in overall health and also helps brain function, can partner with other enzymes to work as an antioxidant, encourages red blood cell production, and maintains collagen and elastin, aiding in bone health. In general, most of us get plenty of copper from our diets so there is generally no need to self-supplement with copper. (Too much copper can also cause unpleasant side effects, such as nausia and diarrhea.) TO CLEAN: We recommend you clean your cup with warm water and a drop of soap before using for the first time. Hand wash is preferred. Copper oxidizes naturally and needs to be cleaned at regular intervals. Sprinkle a pinch of salt on a slice of lemon, allow the salt to dissolve, and then gently rub in on the surface of your cup.
