Meet Wonderbelly’s Founding Bellies
Our mission is to create clean digestive health medicine in sustainable packaging, so you always feel good about feelin’ good.
HI, I'M LUCAS. The co-founder and CMO of Wonderbelly.

Here’s the section where I get to tell you about my story, and to be honest, it’s a lot to digest. Sorry, I had to. Now I’m going to put the puns away and get real, because not all of it is easy to stomach. Ok, ok, now I swear that was the last one...

I’ve had digestive health issues for quite some time, and though I’ve always been aware of the root cause, it took me a long time to feel comfortable talking about it. I developed bulimia, an eating disorder, when I was 15 years old and suffered from it for more than 10 years. I fortunately recovered in my twenties, but by that time, I had developed a pretty problematic digestive system including conditions like GERD (chronic heartburn/acid reflux) and Barrett’s Esophagus (Read more about Lucas’ journey here)

For years after I recovered, I treated my symptoms with a wide variety of digestive health products until I became aware of some of the ingredients that went into them. I wanted to treat my gastric problems without the extra additives, artificial dyes and chemicals used to make these digestive health products. Plus, it’s not like I enjoyed the taste of any of these old pharmaceutical products anyways. But once I opened my eyes to the ingredients going inside my body, I became motivated to find an alternative solution. The problem was that there really wasn’t one. So my brother, Noah, and I started Wonderbelly to create the products that we couldn’t find.

Wonderbelly’s mission is to provide clean, sustainable and effective digestive health medicine, starting with common, everyday heartburn. With the help of top professionals in the pharmaceutical industry and gastroenterologists, we developed our first product, Wonderbelly Antacid: a non-GMO, clean ingredient antacid, free of talc, dyes, gluten, dairy, common allergens, synthetic sweeteners, and artificial flavors. But we didn’t stop there. I’ve always been passionate about protecting the environment, and after realizing that basically all pharmaceutical products come in virgin plastic packaging, we committed to using 100% plastic-free packaging for all Wonderbelly products!

Our vision is for all people to treat their digestive health issues without dumping junk into their bodies or our planet. Wonderbelly Antacid is step one of that vision.

Will Wonderbelly Antacid work for me?

Wonderbelly Antacid’s active ingredient is calcium carbonate. Calcium carbonate is an antacid that can relieve heartburn, acid indigestion, sour stomach, and upset stomach associated with these symptoms and is found in many of the leading brands on the market such as Tums, Rolaids, and Alka-Seltzer. If you are experiencing other symptoms or your symptoms persist for more than two weeks, you should consult with your doctor or pharmacist to determine the appropriate treatment option.

How long does it take for my order to ship?

Orders will usually ship within 1-2 business days. We process and ship orders Monday through Friday, not including holidays, in the order that they were received.
