Protease

A natural digestive enzyme that breaks down protein into absorbable amino acids, reducing bloated fullness.

What it is

Protease is a digestive enzyme that breaks down protein from foods like meat, eggs, and dairy into smaller building blocks called amino acids. Supplemental protease is made through natural plant fermentation (the natural process bacteria use to break down fibre) and works across different stomach acid levels. This ensures protein digestion starts quickly so your body can absorb key nutrients.

Also known as: Acid Protease, Digestive Protease

Key benefits

  • Breaks complex dietary proteins into simple amino acids your body can use for muscle repair.
  • Reduces heavy fullness, gas, and indigestion after high-protein meals.
  • Makes protein from food easier to absorb so you get full nutritional value.

Amplified by probiotics

Protease breaks protein into smaller pieces so undigested food does not rot in your lower bowel and cause gas. The amino acids released by protease feed friendly gut bacteria. In turn, probiotics produce nourishing compounds and support a healthy mucus layer on your gut wall, helping your body absorb amino acids comfortably.

Typical dose

10,000–50,000 HUT/day

The evidence

Evidence: strong

Human studies show that taking protease enzymes increases amino acid levels in your blood after meals. Research confirms it speeds stomach emptying and eases symptoms of indigestion after protein-rich meals. (Oben et al. 2008, J Int Soc Sports Nutr) (Roxas 2008, Altern Med Rev)

Safety & who should check first

Protease enzymes are very safe and well tolerated. Speak to a doctor or pharmacist first if you have active stomach ulcers or are taking prescription digestive medication.
