We aimed to discover how vitamin C supplementation affects oxidative stress in individuals diagnosed with chronic gastritis. In this study, we looked at 244 Japanese patients suffering from atrophic gastritis. They were randomly assigned to receive either 50 mg or 500 mg of vitamin C every day for five years.

After analyzing the results, we found notable differences between the two groups. The high-dose group experienced a significant decrease in reactive oxygen species (ROS), suggesting that vitamin C may help reduce oxidative stress associated with chronic gastritis. In contrast, the low-dose group reported an increase in ROS levels. These findings prompt further interest in how vitamin C can protect against oxidative stress in similar conditions.

Overall, our study supports the idea that higher doses of vitamin C could have a beneficial effect on oxidative stress, particularly in those dealing with gastritis. This insight opens avenues for considering vitamin C as a potential supportive treatment for managing oxidative stress-related issues in digestive health.

Vitamin C ineffective for gastritis
We explored the potential benefits of vitamin C supplementation for individuals suffering from atrophic gastritis. Conducted as a double-blind, randomized controlled trial in Japan, this study involved participants living in a region known for high rates of stomach cancer. Over five years, volunteers were assigned to receive daily doses of either 50 mg or 500 mg of vitamin C.

The results were intriguing: while those in the high-dose group had higher levels of serum vitamin C, the levels of two important inflammatory markers—C-reactive protein (CRP) and serum amyloid A (SAA)—showed no significant difference between the low- and high-dosage groups. Both biomarkers remained fairly constant, indicating that vitamin C supplementation did not effectively reduce inflammation or infection risk among these individuals with atrophic gastritis.

Overall, our findings suggest that high doses of vitamin C may not provide the hoped-for relief from inflammation in this patient group. Thus, it appears that vitamin C supplementation alone is insufficient in managing or alleviating gastritis-related inflammation.

Vitamin C improves chronic gastritis
We investigated how vitamin C might help improve chronic atrophic gastritis (CAG), a condition characterized by gastric mucosal damage and inflammation. Our research utilized data from a well-known dataset, focusing on changes in gene expression related to CAG. Notably, we pinpointed IGFBP7 as a central gene that appeared to be strongly associated with this condition.

In our study, we treated CAG patients with vitamin C and observed significant improvements in blood parameters and the overall health of their gastric mucosa. Moreover, when we looked at gastric cells in the lab, vitamin C not only boosted cell viability but also reduced inflammation and cell death caused by a harmful compound known as MNNG. These effects included lowering the levels of inflammatory markers and apoptosis-related proteins.

Interestingly, our findings suggested that IGFBP7 plays a role in these protective effects of vitamin C. When we knocked down IGFBP7 in the lab tests, we noted changes in how vitamin C worked, suggesting a complex interaction.

Overall, our study highlights the potential of vitamin C and IGFBP7 as key players in managing chronic atrophic gastritis and enhancing gastric health, opening doors for new therapeutic approaches.

I'm now ordering this great Vitamin C for the second time. It has proved more effective than sodium ascorbate for my family. Even with gastritis, my mum and I manage it well as long as we don’t take it on an empty stomach. At the first signs of a cold, I take one tablet, often splitting it in half for easier consumption. This method has made my colds more manageable or even made them retreat quicker.

This vitamin C is good, although the tablets are on the larger side, I can still swallow them. Keep in mind that ascorbic acid isn't the best choice for those with gastritis or other gastrointestinal conditions; I’d recommend sodium ascorbate or calcium ascorbate as a non-acidic alternative.

Antioxidants may aid gastritis treatment
We conducted a one-year double-blind placebo-controlled trial to explore the effects of daily supplementation on patients with gastric premalignant lesions known as intestinal metaplasia (IM). Our focus was on a specific supplement consisting of Ester-C, which includes 2100 mg of Ca-ascorbate and 340 mg of bioflavonoids, alongside other antioxidants.

The results were promising, showing a significant decrease in the activity of ornithine decarboxylase, an enzyme that can indicate abnormal cell growth. Remarkably, we observed that 11 out of 18 patients showed nearly total regression of their IM, which translates to a success rate of 61%.

While this study highlights the potential benefits of antioxidant supplementation, including vitamin C, it's essential to note that multiple components were present in the treatment. This complexity makes it challenging to pinpoint the specific effect of vitamin C alone on gastritis treatment.

Vitamin C aids hormone absorption
We sought to understand how vitamin C affects the absorption of levothyroxine, a common medication for hypothyroidism, particularly in patients who also experience gastritis. Our study involved 31 patients, most of whom had poorly controlled hypothyroidism along with gastrointestinal issues.

Participants took levothyroxine alongside a solution that either contained or did not contain vitamin C, and we monitored their hormone levels over several months. Our findings revealed that vitamin C can actually improve levels of free T4 and T3, as well as TSH, suggesting it enhances the absorption of medication in these patients.

This is particularly significant because individuals dealing with both hypothyroidism and gastritis often struggle to maintain stable thyroid hormone levels. Our research indicates that incorporating vitamin C into their treatment regimen could serve as a beneficial strategy in managing their condition.

Vitamin C aids gastritis healing
We explored how vitamin C, or ascorbic acid, plays a role in the development of gastritis, specifically focusing on acute gastric mucosal lesions induced by a compound known as C48/80 in rats. In our study, we injected fasted Wistar rats with C48/80 to trigger gastric lesions, followed by varying doses of oral vitamin C.

After assessing the severity of the lesions and measuring various biochemical markers in the gastric mucosa and serum, we found that lesions appeared 0.5 hours post treatment and continued to worsen over the next 3 hours. Notably, the administration of vitamin C right after the initial treatment appeared to significantly reduce the progression of these lesions. It also helped maintain the levels of various protective substances in the gastric lining and overall health indicators.

By the end of our study, it was clear that vitamin C has a crucial protective effect in this scenario. Our results suggest that timely vitamin C administration can prevent the worsening of gastritis caused by mast cell degranulation. This adds a promising angle to the conversation about dietary vitamins in managing gastric health.

Vitamin C helps combat gastritis
We explored the effects of Ascorbic Acid 2-Glucoside (AA2G), a stable form of Vitamin C, on human gastric epithelial cells infected with Helicobacter pylori, a common cause of gastritis and related stomach issues. In our research, we focused on understanding how AA2G could mitigate the damage caused by this bacterium on stomach cells.

Our findings revealed that AA2G significantly reduced oxidative stress—a harmful condition triggered by H. pylori that can damage cells. We observed that treatment with AA2G led to lower levels of harmful substances, such as reactive oxygen species, known to contribute to cell damage.

Notably, AA2G also helped restore the cells' mitochondrial function, which is often impaired during H. pylori infection. This improvement included an increase in ATP levels and enhanced mitochondrial membrane potential, both essential for cell energy production and health.

Ultimately, we found that AA2G effectively reduces the apoptosis (or programmed cell death) that results from H. pylori infection, suggesting that it provides a protective effect on gastric epithelial cells. Our research supports the potential use of AA2G as a beneficial intervention for combatting the adverse effects of H. pylori infection on gastritis.

Our research supports the potential use of AA2G as a beneficial intervention for combatting the adverse effects of H. pylori infection on gastritis.
We aimed to understand how vitamin C, alongside vitamin E, affects inflammation in the stomach caused by Helicobacter pylori, a common bacteria linked to gastritis. In our study, patients suffering from nonulcer dyspepsia and testing positive for H. pylori were given vitamin C (500 mg) and vitamin E (200 IU) twice daily for four weeks.

After this treatment period, we collected tissue samples from different areas of the stomach to examine any changes in inflammation and vitamin levels. The results showed that vitamin C levels increased significantly in the stomach mucosa, alongside vitamin E levels.

More importantly, both the intensity of H. pylori and neutrophil activity, which indicates inflammation, decreased after supplementation. This suggests that taking these vitamins could help create a less favorable environment for the bacteria, potentially improving treatment outcomes for gastritis.

Overall, while our findings highlight the importance of vitamins C and E in reducing stomach inflammation, they also suggest that these vitamins may help improve the effectiveness of conventional treatments against H. pylori.
We explored the effects of vitamin C on gastritis through a study involving 51 patients who had multifocal atrophic gastritis (MAG) and 92 matched individuals with dyspeptic symptoms. The goal was to see how well vitamin C worked alongside the eradication of Helicobacter pylori, a bacteria often linked to gastritis.

Our findings revealed that while vitamin C, taken in large doses for three months, along with H. pylori treatment didn't reverse the histological damage to the gastric lining, it did improve the functional capabilities of the affected stomach. Specifically, we observed better gastric acid and gastrin levels, reduced expression of certain premalignant markers, and an increase in growth factors.

These results suggest that vitamin C can enhance some aspects of gastric health in patients with MAG, but it is not a standalone cure. The study emphasizes that gastritis is influenced by various environmental and biological factors, and while vitamin C shows promise, it needs to be part of a comprehensive treatment strategy.
