Works very well. Upset stomach quite often. Helps with minor aches and pains and the effervescence helps settle the tummy when I've eaten too much, alka seltzer will make i feel better in 5 minutes, even if just a little. I love this stuff. Especially if I have a stomach ache.

[This review was collected as part of a promotion.] I took this when I had a headache and muscle aches from a cold. It did wok to relieve the pain, but so could barely choke it down because the taste was awful. It literally tastes like a crushed up aspirin dissolved in water. I would not purchase unless Alia Seltzer added flavor to make it taste better.

I have only ever used this whenever I have had stomach issues. This honestly works effectively and quickly for me. I guess I never paid too close attention to see that it can also be used for heartburn (good to know) and other ailments. I cannot speak to those but if ever you have a stomach ache grab one of these.

[This review was collected as part of a promotion.] I've been using Alka-Seltzer for years now and they've always helped me with my headaches and any body pain. I recommend this product for anyone who suffers from any pain. I'll be positing this on my Instagram too. I give it 5 starts!

[This review was collected as part of a promotion.] I have mixed feelings about this product… so let's start with the positive first… I tried this product for the first time after a super intense weekend at the gym which left me with a terrible tension headache. Enter Alka-Seltzer. For some reason watching and hearing the tablet dissolve was so satisfying and provided quick headache relief.. however the taste was terrible and I had a hard time finishing my glass of water…. "I received these products complimentary from Influenster for testing purposes".

[This review was collected as part of a promotion.] I have a very sensitive stomach and don't tolerate ibuprofen in pill form well. This is a great alternative, providing quick pain relief without causing stomach discomfort. Within an hour my joint pain was reduced!

[This review was collected as part of a promotion.] I like keeping these in my bag for on the go, they are prepackaged so you can easily just throw it in your purse. It's a huge box of them too so it'll last you quite a while give or take how often you use them!

I know these are supposed to be used for heartburn, but with the quarantine, I've been desperate to find ways to keep my 4 year old daughter entertained, and these little tablets have led to lots of science fun. Today's adventure was making a "snowstorm in a jar". She loves her alka-seltzer tablets.

[This review was collected as part of a promotion.] I took these tablets while suffering from a mild headache. Preparation was simple. I do wish it had a better flavor, but I was impressed at how quickly my headache was gone. Despite not caring for seltzer flavor too much, I would definitely use these tabs again as they really did work to reduce my headache.

[This review was collected as part of a promotion.] This stuff works amazing! I never knew what it was, other than like heartburn relief! It helps with headaches,heartburn, stomach pain, etc! I would buy this now that I have used this product before!
