We aimed to understand how Vitamin C could help with the toxicity caused by omeprazole, a common treatment for conditions like gastroesophageal reflux disease (GERD) and gastritis. During our study, we examined gastric cells from rabbits to see how Vitamin C, alongside other antioxidants, could protect these cells from damage caused by omeprazole.
We found that both omeprazole and another thiol-oxidant, monochloramine, significantly reduced cell viability. Interestingly, the toxicity from omeprazole occurred independently from monochloramine. However, we observed that using Vitamin C effectively protected the gastric cells from this injury, maintaining their function without interfering with omeprazole's intended effects.
This suggests that incorporating Vitamin C into treatment plans for people using proton pump inhibitors (PPIs) like omeprazole could be beneficial. Ultimately, our research highlights the potential of using antioxidants to mitigate the adverse effects often associated with medication for reflux and related conditions.

Antioxidants may reduce cancer risk
We studied how antioxidants, particularly vitamin C, relate to reflux esophagitis and esophageal adenocarcinoma, aiming to uncover potential protective effects. Through a case-control approach involving groups with reflux esophagitis, Barrett's esophagus, and esophageal adenocarcinoma, we assessed the dietary intake of antioxidants and their relationship with these conditions.
Our findings revealed that a higher overall antioxidant intake was linked to a reduced risk of esophageal adenocarcinoma. Specifically, individuals with the highest vitamin C intake had a significantly lower risk of developing this type of cancer. However, while vitamin C also appeared to reduce the risk of reflux esophagitis, we found no strong connection between vitamin C and Barrett's esophagus, nor with other antioxidants such as vitamin E, carotenoids, zinc, copper, or selenium.
This suggests that while antioxidants could play a role in lowering the risk of esophageal adenocarcinoma, they might be more influential in terms of progression rather than initiating reflux conditions. Overall, our study highlights the potential significance of dietary vitamin C in addressing reflux issues but points out limitations when it comes to other forms of esophageal disorders.

No heartburn issues
86 people found this helpful
NOW brand doesn’t trigger heartburn or acid reflux in my wife. We’ve tried other vitamin C brands that caused her awful heartburn. We've been using NOW vitamin C for a while now (on our second bottle) and she hasn’t experienced any heartburn or acid reflux issues. The pills are not particularly small but are manageable. I can’t recall the last time I was sick, and I genuinely believe that taking vitamin C contributes to that. I typically take two tablets a day (2000 mg total), one with breakfast and another with dinner, and I increase to four when in crowded situations.

Great immune support
This vitamin C is fantastic as it does not cause acid reflux after I take it. It’s gentle on my stomach and great for my immune system.
