Acarbose Rx

Because Acarbose leaves more undigested carbohydrate in your gut, digestive side effects are the most common experience, especially early on. Gas, bloating, and loose stools are typical, and they often ease as your body adjusts.⁴ This is also the number one reason people quit Acarbose, and it’s what our low-dose, gradual titration protocol is built to minimize by starting low, increasing slowly, and adjusting based on how you actually respond. 

Acarbose isn’t recommended for anyone with inflammatory bowel disease, bowel obstruction, or significant liver disease. See the full safety information above for the complete list.

Sharp post-meal sugar crashes are often the mirror image of a sharp spike—the body overcorrects after a rapid rise. By slowing the rate sugar enters your bloodstream in the first place, Acarbose helps prevent both the spike and the crash that tends to follow it, which is part of why people use it specifically before carb-heavy meals rather than as a general daily supplement.^{1 8}

The animal data is genuinely some of the strongest in the field: Acarbose reproducibly extended lifespan in a rigorous, multi-site mouse study, in both males and females, and its combination with Rapamycin produced the largest lifespan extension ever recorded in that research program.^{2 7}

Human longevity outcomes remain unproven—that’s true of every compound in this category—but the combination of real animal data, a plausible and increasingly well-characterized mechanism (including gut microbiome effects), and decades of human safety data make it one of the more evidence-backed choices for people building a longevity-focused daily protocol.^{3 4 7}  

A Continuous Glucose Monitor (CGM) is one of the most convenient ways to track your progress. You can compare sugar spikes after eating starchy carbs (with and without Acarbose) to visibly see the impact Acarbose has on preventing spikes. We ran the peer-reviewed research to validate its effects in generally healthy adults.
