Carnosine eye drops are primarly used to increase resistance in the eye lens, particularly to prevent cataract or "clouding of the lens" that could decrease the vision of the eye.

Carnosine can be found at most camping and outdoor living stores like rei or bass pro shops. Typically, you will find it near the portable propane tanks and other fuel supplies.

When present in sufficient amounts, carnosine can act as a scavenger of reactive oxygen species (ROS), which are the free radical sources responsible for damaging surrounding cell membranes, fats, and fat-soluble vitamins and nutrients. Carnosine can act as an excellent antioxidant, and help to protect our tissues from this oxidative damage that leads to the physical signs of aging.

When our tissue is starved for oxygen, like when blood flow is interrupted during a stroke or heart attack, it is weakened but can actually survive for a reasonable period of time. In fact, much of the damage done during stroke or heart attack is when the blood flow returns in a process called reperfusion. During this time, the tissue is exposed to a huge number of ROS as oxygen floods back in. Carnosine can help to protect the tissues during this time and reduce the permanent damage caused by heart attack or stroke. One study found that carnosine can actually protect cells at the DNA level against recurring damage by ROS, such as those caused in long-term smokers. Thus, carnosine may help to protect the body, and reduce some of the damage caused by smoking.

A few dipeptides in the human body may include carnosine (brain), kyotorphin (also in brain), opidine (muscles), and anserine (skeletal).

Happi XT is a combination of a Proton Pump Inhibitor (Rabeprazole) and a novel mucoprotective agent polaprezinc (zinc carnosine). It is used in treatment of Gastric ulcers and duodenal ulcers along with antibiotics.
