When most people think about bulking supplements, their minds jump straight to protein powders, creatine, or mass gainers. But Chris Bumstead, Mr. Olympia himself, drops a truth bomb that flips the script—digestion is king.

In this video, Cbum cuts through the noise. The #1 focus for effective bulking isn’t just how much food you eat, it’s how well your body uses it. If you’re force-feeding yourself six times a day but your digestion is wrecked, you’re not growing—you’re just bloated and uncomfortable.

Chris lays out his go-to stack for optimizing digestion and making sure every bite counts. At the center of it all? GDAs—glucose disposal agents. These help your body efficiently shuttle carbs into your muscles rather than letting them float around or get stored as fat. Cbum mentions two standout products: Evil Log by Hany Rambod, which combines digestive enzymes with GDA ingredients, and Glucose by Revive MD, a stronger standalone GDA formula.

Both options work to make your meals more effective by supporting insulin sensitivity and nutrient partitioning. He also stresses that he’s never touched insulin—something some bodybuilders use to drive more nutrients into their muscles—but prefers safer, natural methods to achieve similar effects.



Next up: digestive enzymes and betaine HCl. Chris explains that many people simply don’t have optimal stomach acidity, especially when consuming high amounts of protein like a bodybuilder does during a bulk. These supplements take the load off your gut, making the digestion process smoother, faster, and more effective.

The bottom line? If your stomach isn’t working at 100%, your gains won’t be either.

Chris sums it up with a reminder every lifter should hear: when digestion is off, bloating sets in, appetite crashes, and soon you’re missing meals. And when that starts happening consistently, your whole bulking phase starts to fall apart.

So if you're trying to grow, build mass, and pack on real size—take care of your gut first. Because as Chris says, “Digestion is absolutely everything.”
