"It's a multi-enzyme digestive supplement containing 14 different enzymes, most of which your body already produces naturally."
Claims vs Evidence
MODERATE0 of 3 claims supported by evidence.
"help digest different types of foods"
Partial
Enzymes act locally in gut; effectiveness in healthy adults unproven.
Based on: Proteases, Lipase, Amylase, Cellulase, Glucoamylase, Lactase
"ensure complete digestion of carbohydrates, fats, proteins, and fiber"
Stretch
Word 'complete' is overstated; human GI tract already produces these enzymes.
Based on: Full Spectrum pH Protease Blend, Lipase Blend, Amylase, Cellulase Blend
"enzyme levels based on a typical meal"
Unsupported
No clinical evidence supports these specific dose ratios for human digestion.
