Digestive enzymes

Digestive enzymes are from 3 sources,

Animals,plants,microbes.

Animal sources include,

Pancreatic,pepsin,trypsin,chyme trypsin.

Pancreatic is most widely used and has most of the enzymes necessary for digestion in small intestine.

It has protease to breakdown proteins into aminoacids,amylase to to cleave complex carbohydrates to simple sugars,lipase to break down lipids.

Plant sourced enzymes

Bromelain( from pineapple)

Papain from papaya

Ficinfrom fig tree latex

Actinidin from kiwi fruit 

These are proteolytic enzymes which break down proteins

They also help reduce inflammation.

Papain is contraindicated in Pregnancy.

Microbial sourced enzymes

Usually from fungi and bacterial sources can be used by vegetarians,vegans.

They survive well in stomach.

The microbial enzymes include Amylase,glucoamylase,protease,lipase and various saccharidases.

The latter include lactase to digest lactose,Alfa- galactosidase ( for digesting beans,legumes,Cruciferous vegetables.

These also have cellulose to digest cellulose,along with hemicellulase ,xylanase,pectin apse imp 

for digesting plant components.

Formulas with high cellulose activity( 2000-4000CU is of big help in digesting legumes and high fiber 

plant foods.
