GastroBlast™ is a blend of botanical extracts and nutrients with specific antimicrobial activity and gastric mucosal supportive properties.* This combination of substances can be helpful in the management of ulcers and gastritis caused by H. pylori as well as supporting a healthy gastric mucosal tissue.* It is delivered in quick-release capsules formulated for dissolution and action in the stomach and duodenum.
The stomach lining contains a thick layer of mucus that protects it from the harsh acidity of the gastric juices, which are necessary for digesting proteins and killing unwanted organisms that may enter the digestive tract. However, some of these organisms can withstand the acidic environment of the stomach and damage the lining of the stomach, leading to abdominal pain.
Similarly, stress, environmental toxins, a poor diet, dehydration, and an imbalanced composition of organisms in the intestines can also lead to stomach issues such as occasional bloating, heartburn, and an upset stomach.* GastroBlast™ focuses on helping to rebalance the organisms in the stomach and restore a healthy mucosal lining.
Mastic gum (Pistacia lentiscus) is a resinous substance from a tree native to Greece and has been used for over 2500 years in the Mediterranean where it is chewed like gum for the purpose of ameliorating stomach pain.1
Modern scientific research has validated the antimicrobial properties of mastic gum, with human and in vitro studies showing it to be effective against multiple strains of H. pylori as well as against E. coli and S. aureus.2-5
Mastic gum may also have anti-fungal and anti-inflammatory properties. In vitro studies demonstrate that mastic gum dose-dependently inhibits the production of the superoxide radical and hydrogen peroxide in rodent cells treated with the inflammatory compound TNF-α.6
Mastic gum did not scavenge the free radicals; rather, it reduced their production, leading researchers to hypothesize that this action is likely responsible for some of the anti-inflammatory activity of mastic gum. Mastic gum has been identified as a PPAR agonist, so it may favorably affect processes that result in inflammation or oxidative stress at the level of gene expression as well.7
A randomized, double-blind trial investigating the effects of mastic gum on functional dyspepsia found that compared to placebo, mastic gum resulted in significant improvement in stomach pain in general, stomach pain when anxious, heartburn, and dull ache in the upper abdomen.8
Human and animal studies demonstrate mastic gum’s efficacy in improving duodenal ulcers and protecting against gastric ulcers.9,10
Methylmethionine Sulfonium (MMS) is a derivative of methionine found in raw cabbage and is often referred to as “vitamin U”, although not technically a vitamin, owing to its being a food-derived factor identified as beneficial for helping with peptic ulcers.
The use of MMS-rich raw cabbage juice has been studied extensively for its beneficial role in aiding healing of damaged and eroded intestinal mucosa. Human research dating back over 70 years supports the use of raw cabbage juice for dramatically improving gastric and duodenal ulcers, including among subjects who made no other changes to their diet or medication regimens.11-14
The antacid drug famotidine typically suppresses the synthesis and accumulation of mucin. Research in rodents shows that oral administration of MMS protects against this suppression.15
Anticonvulsant treatment with valproic acid (VPA) has been demonstrated to lead to gastritis and other gastric disturbances in some patients. Animal models show that MMS protects against VPA-induced damage to the liver, kidneys and eyes, likely owing to anti-inflammatory and antioxidant properties. It is possible this compound may exert similar effects in gastric tissue.16-18
Deglycyrrhizinated Licorice (DGL) is a well-established anti-ulcer and mucosal supportive botanical. DGL is a mucilaginous herb that supports healthy intestinal function by coating and soothing the intestinal lining and promoting the healing of ulcers and inflamed tissue.
GastroBlast™ contains a potent form of DGL standardized to contain less than 3% glycyrrhizin and guaranteed to contain .75% flavonoids (as glabridin and glabrol). This extract is up to 10 times higher in bioactive flavonoids than non-standardized DGL, and these flavonoids play a major role in improving gastric damage. The flavonoids in licorice have powerful antimicrobial activity against H. pylori, including against strains resistant to clarithromycin and amoxicillin.19,20
The high-flavonoid, very low glycyrrhizin content of this unique DGL allows this botanical extract to work efficaciously without the potential side-effects of high-dose full-spectrum licorice consumption (e.g., hypertension, hypokalemia or fluid retention). In vitro research shows that DGL extract inhibits the adhesion of H. pylori to human stomach tissue—an effect believed to be related to the polysaccharides isolated from DGL (similar to the role of cranberry compounds preventing adhesion of UTI-causing bacteria in the bladder).21
Isolated DGL polysaccharides did not show direct cytotoxic effects against H. pylori, so select compounds in DGL appear to be effective for preventing initial H. pylori colonization, while other compounds with antimicrobial, antiviral and anti-inflammatory properties may be responsible for the observed antiproliferative effects.22,23
Zinc Carnosine is included in GastroBlast™ based on research showing zinc to have beneficial effects for supporting gastric tissue, such as combating H. pylori, supporting the mucosal layer and protecting against ulceration.24
This extends to protecting the intestinal lining against damage induced by anti-inflammatory medications often associated with intestinal mucosal damage. Compared to placebo, zinc carnosine was shown to neutralize the effect of the NSAID indomethacin on increasing gut permeability in healthy human subjects. (The placebo arm experienced a three-fold increase in gut permeability while the zinc-treated group showed no significant change.25)
In a trial of patients with small bowel injury induced by extended use of low-dose aspirin, compared to untreated controls, subjects taking zinc carnosine for four weeks showed significant reductions in the number of reddened lesions and erosions/ulcers, confirmed by capsule endoscopy before and after.26
Zinc carnosine—zinc complexed with the amino acid L-carnosine in a 1:1 chelate—is the preferred form of zinc for this formula because it remains in stomach juice without rapid dissociation and adheres to ulcerous lesions more effectively, after which the L-carnosine and zinc are separated and have beneficial effects on the affected tissue.27,28
Vitamin C is included for its anti-H. pylori activity as well as its role in tissue regeneration. Vitamin C may be effective both restoratively and prophylactically, although more evidence supports the latter. Low levels of vitamin C in serum and gastric juices have been consistently found in subjects with gastritis and peptic ulcers associated with H. pylori.29
Research indicates a high concentration of vitamin C in gastric juice may inactivate H. pylori urease, an enzyme the organism uses to protect itself against the acidic environment of the stomach, allowing it to colonize.30
As vitamin C is needed for wound healing, it has been shown that patients with bleeding peptic ulcers have lower vitamin C levels than patients with non-bleeding ulcers. Vitamin C deficiency is associated with all forms of gastritis, including autoimmune (pernicious anemia), experimentally induced, and due to H. pylori. Researchers note that H. pylori-induced gastric inflammation “can decimate total body ascorbic acid stores by continually quenching high levels of ascorbic acid at inflammatory sites and destroying it in a hypochlorhydric environment.”31
Since vitamin C deficiency may be as much a result as a contributor to these issues, it is prudent to include vitamin C in a formula designed for patients with gastric inflammatory conditions. Regarding gastric health in general, it is hypothesized that vitamin C may have a role in protecting against gastric cancer induced by N-nitroso compounds, known to be carcinogenic. Vitamin C may help inhibit formation of N-nitroso compounds in gastric juice.32
