OHTA'S ISAN Antacid Herbal Powder Single USE16 Packets for USA -Made in Japan

One of the best antacids I’ve tried and very effective when used occasionally. However, it doesn’t seem to work as well if I use it too often. Still a great product to keep on hand when needed.

This really works. While it doesn't smell good when you first put in your mouth, the herbal power helps with reducing acid in less than one hour. I strongly recommend!

Amazing, so gentle on my sto.ach and works very fast after drinking. My stomach feels so much relief and ease. It smells very good with the natural ingredients included.

I first tried OHTA’S ISAN about 10 years ago during a trip to Japan when I had really bad stomach pain after a long day of eating and walking. A local shop owner recommended it to me, and I still remember how fast it worked — within moments the discomfort was gone. Since then I’ve been hooked, but it was always hard to find back home, so I was honestly so happy to see it available here. Now I keep a few packets in my bag for those days when I overeat or get acid reflux from coffee or late-night meals. It works quickly and I don’t need to keep taking more throughout the day. The powder has a strong herbal, slightly salty taste, but I’m used to it and the relief is totally worth it. If I could suggest one thing, it would be a bigger pack for frequent users like me. Overall, this is still my most trusted stomach remedy after all these years — five stars without hesitation.
