Discussion
Gastrex is designed to support the gastric phase of digestion directly and provide stimulus for the excretion of
pancreatic digestive juices in the small intestine. Adequate hydrochloric acid is fundamental to healthy protein
digestion, nutrient availability, and the maintenance of normal gastric flora.[1-3] There is a natural decline in
the ability to produce hydrochloric acid, especially after the age of 60.[1] There appears to be an even greater
decline in pepsin production related to normal aging.[4] Support of natural gastric secretions and acidity helps
support normal digestion, absorption, and immune health.[5] Maintaining an acidic pH in the stomach helps
support normal gastric and intestinal flora as well.*[6-8]
L- Glutamic Acid This amino acid can be obtained from dietary protein or synthesized endogenously from
other amino acids, such as glutamine. L- glutamic acid is used in Gastrex as an acidifying agent.*
Betaine Hydrochloride (HCl) Betaine (also known as trimethylglycine) is a natural substance found in foods
such as beets, spinach, and grains. Research suggests that betaine supports cell health by acting as a methyl
donor, and this, in turn, supports healthy methionine, homocysteine, and hepatic fat metabolism. Betaine also
functions as an osmolyte, which supports the integrity of cells and proteins during fluctuations in hydration,
salinity, and temperature. Betaine HCl, the acidic form of betaine, has traditionally been used to support
digestion and absorption due to its ability to lower gastric pH.*[9,10]
Pepsin One of the first enzymes to initiate protein digestion, pepsin is first synthesized in the parietal cells of
the gastric mucosa and secreted as the inactive zymogen precursor pepsinogen. Hydrochloric acid activates
pepsinogen to convert it to pepsin once it is outside the cell. This activation sets up a chain reaction leading to
the production of still more pepsin. Porcine pepsin, in addition to betaine HCl, is provided in Gastrex with the
goal of promoting more endogenous pepsin production.*[4,6]
Gentian Root (Gentiana lutea) Used for centuries to support healthy digestion, gentian contains the bitter
glycosides gentiopicrin and amarogentin. Gentian’s bitter taste can be detected even at a dilution level of
50,000:1. Gentian root appears to support digestion by stimulating secretion of saliva in the mouth, hydrochloric
acid in the stomach, and digestive juices from the pancreas. Due to the stimulant effect that gentian root has
on endogenous production of HCl, individuals may be able to discontinue Gastrex after a period of use.*[11-14]
Gastrex is formulated with a variety of compounds and is designed to support gastric acidity, digestion, and
normal gastrointestinal flora. Gastrex should be taken with, or immediately following a meal. Do not use if there
is a prior history of, or a current complaint of, a peptic or duodenal ulcer.*
