PepZin GI™ is an exclusive, patented complex of zinc and
L-carnosine that was first developed in Japan and has been in
use since 1994.1 This special chelated form of the mineral zinc
has a unique ability to exert its effects directly on the cells
of the stomach lining. When zinc is complexed to L-carnosine, it
dissociates in the stomach at a slower rate. This prolonged
existence allows it to maintain its gastric healing effect over
a longer period of time.2 The proprietary chelation process
along with excellent scientific research make PepZin GI™ your
best choice for supporting gastric health.

PepZin GI™ helps relieve occasional discomfort.*

CLINICAL TRIALS

In a randomized, multi-center, placebo-controlled double blind study, 299 patients suffering with symptoms of gastric discomfort were randomly allocated to receive either a zinc-L-carnosine complex or a placebo, or a control drug or its placebo for 8 weeks. Improvement ratings for a range of symptoms were taken at various points during the trial and compared with before treatment data. Of the 258 people who completed the trial, 136 were in the zinc-Lcarnosine group. Of the group, 92% of the participants were rated as “moderately improved” or better on an improvement scale across the category of symptoms including heartburn, tenderness, epigastric pain, diarrhea and constipation after 8 weeks.3

In another study, 28 patients with gastric discomfort were given a zinc-L-carnosine compound and monitored for 8 weeks. Improvement was rated on a scale of subjective and objective symptoms. After 4 weeks, the rate of those cases that were considered to be “significantly improved” was 68.4%. After eight weeks, the “significantly improved” number was 68.8%. Over 60% of these patients remained in the “significantly improved” category well after discontinuation of the treatment, suggesting a lasting effect of the zinc-L-carnosine compound beyond the time it is taken.4

Maintains a healthy GI environment.*

The mineral zinc in PepZin GI™ is a critical component to a number of physiological processes in our bodies. Some of these functions include growth and metabolism of cells, healing of wounds,and maintenance of carbohydrate and lipid metabolism.2

PepZin GI™ may also be able to favorably maintain the bacterial balance of the stomach and GI tract. Studies suggest that the zinc-L-carnosine co m pound may have effects on certain strains of harmful bacteria and, therefore, may be able to help maintain a GI environment that is favorable to health.1 By supporting the bacterial balance in the stomach, PepZin GI™ can help maintain a healthy mucosal lining.

Supports the health of gastric cells.*

PepZin GI™ has been studied for its ability to prevent free radical damage to gastric cells. In one such study, rat gastric cells were exposed to ethanol and hydrogen peroxide, two substances known to cause free radical damage to living cells. Cells were bathed in hydrogen peroxide, ethanol, zinc-L-carnosine, or a combination of zinc-L-carnosine with either ethanol or hydrogen peroxide. While the cells bathed in ethanol and hydrogen peroxide solutions all exhibited signs of damage due to free radical production, the cells that were bathed in zinc-L-carnosine were largely protected from the effects of free radical damage. The authors concluded that the zinc compound directly protected gastric mucosal cells from oxidant stress and alcohol induced damage.5

Additional research further confirms the gastro-protective effects of PepZin GI™. In another rat study, stomach lesions were induced by administration of the chemical monochloramine, a known pro-oxidant (producer of free radicals). One of the groups of rats was fed the zinc-Lcarnosine compound prior to being exposed to monochloramine. The researchers found that the size of the lesions in the group pre-treated with zinc-L-carnosine was significantly less than the lesions in the control group. The authors concluded that the zinc compound exerted a beneficial protective effect against monochloramine-induced stomach lesions.6

The zinc-L-carnosine in PepZin GI™ has also been shown to slow the development of aspirin induced stomach damage in rats. The researchers measurably detected lower levels of TNF-alpha in rats given zinc-L-carnosine as compared to the control rats. TNF-alpha is an inflammatory cytokine that is known to be released in response to gastric damage.7 These results may suggest a role for PepZin GI™ in protecting gastric cells by occasionally reducing the levels of certain cytokines in minor inflammation of the stomach.
