Enzymes: Powerful Yet Safely Controlled

Your body makes enzymes so powerful they could digest you from the inside. That's why they're

created in an inactive "safe mode," like a locked weapon. Take Pepsin, the protein-smasher

in your stomach. It's born as harmless Pepsinogen. Only when it hits your stomach acid

does it activate and start breaking down your steak, not your stomach lining.

The same goes for Trypsin in your intestine; it's switched on right where it needs to

work. It's a perfectly timed chemical demolition crew, turning big food

molecules into tiny fuel pieces your body can actually use.
