We Were Tired of TUMS

So We Made It Better

Heartburn is tough.

Finding a clean, tasty and sustainable antacid to soothe it is tougher.

Meet Wonderbelly

A maximum strength (1000mg calcium carbonate), instant relief antacid for heartburn, acid indigestion and upset stomach.


Heartburn Dilemma

Heartburn is tough. What’s tougher is finding clean and healthy medication to deal with it. Your antacid should not:

Contain junk ingredients like TALC, Titanium Dioxide,
and Food Colorings

Taste like chalk and kill your appetite further more

Be packaged in plastic that becomes bad turtle food

Instead we took Wonderbelly antacids to the next level:

After 4 days, Strawberry Milkshake has already banished my heartburn issues. I have become so accustomed to that icky feeling that I forgot what it was like to feel heartburn relief! I’ve already ordered another WonderBelly variety pack. I’m HOOKED!

Much Better Option!!

I’m so glad there’s a better-for-you antacid option now! I’ve been using Tums for years and when I hit 30, it felt like I was needing them all the time. Me and my friends felt much better about taking Wonderbelly (quite a few of us have stomach issues, love that for us), vs Tums and some of the other options on the market. Great product – worked as advertised and was definitely a better/cleaner option! I will definitely reach for Wonderbelly moving forward.

Hated TUMS But Had Reflux...TGFWonderbelly

Never had issues until recently (getting old) but when i used TUMS i decided I would just deal with it bc of the consistency and taste. Tried all 3 flavors and tbh, I like them all! Well done, appreciate the help!

Meet Noah & Lucas

Hi y’all!

I’m Lucas, co-founder of Wonderbelly. I struggled with bulimia for over 10 years which resulted in a pretty problematic digestive including a condition called GERD which is basically chronic acid reflux and heartburn.

I’ve tried everything to from dramatic lifestyle changes, supplements and holistic remedies to try and soothe my GERD symptoms but at the end of the day, it was pharmaceutical products like TUMS and Zantac that were the most effective.

Even though I never fully enjoyed the taste of TUMS, it got the job done. However, after a recall of the medication, Zantac, due to a carcinogenic ingredient, I ended up looking at the back of my TUMS bottles as well and noticed they contained ingredients like talc, titanium dioxide, polyparabens, artificial sweeteners and endless amounts of dyes. I was familiar with those ingredients and their reputations so I had no interest in putting them into my body. So I put together a team of top knotch pharmaceutical professionals, gastroenterologist and came up with Wonderbelly.

The goal was to create an equally effective product as TUMS by using the same active ingredient but eliminate the unnecessary stuff like talc, artificial dyes, artificial flavors, parabens and titanium dioxide. While we were at it, we decided to improve the taste, make it less chalky and put it in 100% plastic-free packaging. If we were going to make a change for the better, we wanted it to be in every aspect.
