Reviewers Say This High-Quality Collagen Powder Is Easiest On The Gut 

Collagen doesn't have many side effects, but one of the most common short-term gripes is an upset stomach. ​​It's all anecdotal at this point, but some individuals do report bloating, stomach upset, and fullness. Why do we bring this up? Well, we suspect it might have more to do with another triggering ingredient in a specific formula than collagen peptides in general. And if you're looking for a collagen powder with clean ingredients that won't leave you with an unsettled tummy (or a bitter aftertaste), you've come to the right place. 

And besides, collagen itself is associated with gut and digestive health benefits.* Take this two-phase clinical study1, for example, in which 40 healthy women took 20 grams of bovine collagen peptides each day, split into two servings. After eight weeks of collagen supplementation, 93% (13 out of 14 women) of those who completed the study experienced noteworthy improvements in digestion, including bloating and abdominal comfort.* 

That said, it's no wonder people (and their tummies) are loving this cutting-edge blend. Donna A., for example, finds mbg's collagen powder "very easy to drink with no aftertaste." As she shares in a review, "It agrees with my gut, which is usually a problem." Virginia S. found similar success: "I've tried other brands, and this was easiest on my stomach," she writes. Given the powder's stellar ingredients list and commitment to clean, high-quality standards, it's not difficult to see why. 

If you've experienced stomach upset from your collagen powder, you're not alone. While the side effect isn't too common, it is one of the more popular complaints—but it likely has to do with the "other" ingredients in your formula than the collagen itself. Perhaps try a different brand (ahem, like ours), or feel free to check out the rest of our vetted formulas.
