Great product
Love all the Genexa products. These antacids are so much better than Tums. They taste great and work really well.

Clean Ingredients & Easy to Take 👍🏻✨ Nice Alternative to Chalky Tablets ⭐✨
We’ve been using this for a few months now, and it’s been a convenient option to keep on hand when I need quick, everyday support after meals. Pros: the chewable tablets are easy to take, the clean ingredient approach is reassuring, and the tablets don’t have a chalky texture compared to some similar products. I also like that they’re individually easy to carry for home or travel. Cons: the flavor may be a little mild if you’re used to stronger-tasting chewables, and you do need to follow the suggested serving size carefully. Tip: keeping a small bottle in your bag or nightstand makes them easy to reach when needed, especially when you’re away from home or traveling. I recommend the Genexa Clean Antacid Chewable Tablets, and I hope you find this review helpful 👍🏻

Review of Improved Flavor (plus great effectiveness!)
In response to negative reviews about the flavor, Genexa recently made some product updates. I first ordered this in July 2025 and the taste was so-so. I reordered in November of 2025 surprised to see a change in shape, taste, and texture. These aren’t supposed to be candy, but the taste is a bit better now. I never had major complaints with the first bottle, though. Also, they are now less chalky, so that’s a plus. As far as effectiveness goes, I have been very pleased! I’ve struggled with acid reflux increasingly in the latter half of my pregnancy and these antacids have been a lifesaver (effectiveness has not changed with the update)! I particularly struggled with being woken in the middle of the night by painful acid reflux. A great fix/preventative step for me is to take one tablet right before bed and I haven’t been woken by pain since!

Not the best tasting
These are not the best tasting but I like that they are better ingredients so I will continue to purchase them! The taste isn’t horrible, just definitely not as good tasting as the alternative brand

Great antacid
Love these. The taste is good considering why you are taking it. Relief from heartburn/indigestion is quick. Lid could be better, it tends to snap off.

these taste like dirt
Yes these work for indigestion. Yes,these are clean with no colors & fillers. They also taste like potting soil smells. My daughter and I both think these taste like dirt. Not gonna get these again at the high price
