Karbolyn
Fuel that keeps up.
Steady energy
No spike.
No crash.
Simple sugars hit hard and drop off fast. Karbolyn is a complex carbohydrate that absorbs quickly and releases evenly, so energy holds through the whole session.
Light on the stomach
Mixes clean.
Goes down easy.
Low osmolality means Karbolyn moves through the stomach quickly, so you get the carbs without the bloat or the sloshing.
Recovery
Glycogen, refilled.
Carbs restore the muscle glycogen you burn in training, so you show up ready for the next one.
Where it comes from
Corn. Rice. Potato.
That’s the carb.
