Vitamin Shoppe - Multi-Enzyme, 600 tablets

Also, most enzyme products just give the weight of the enzymes and not the activity. This product label has both. The problem with just listing weight is that 1 mg of a 1,000 LU/g (LU=lipase units, a measure of lipase activity) lipase will not digest nearly as much fat as 1 mg of 120,000 LU/g lipase. So it is possible that a 100 mg enzyme formula can actually digest more food than a 500 mg one.

The strength of the enzymes in this formula is as follows:
Pepsin - 1:10,000 (this Pepsin can, in the lab, digest 10,000 times its weight in protein)
Amylase - 57,000 U/g
Lipase - 120,000 LU/g
Papain - 2,000 USP units/mg (not on label, but I asked them)
Protease - 200,000 HUT/g
Bromelain - 600 GDU/g
Cellulase - 20,000 FCC units/g

Take note that one serving is actually two tablets, and the amounts of enzymes listed in the ingredients list are for two tablets, not one. Overall, this is a good formula that is around half the price of Health Food Store enzymes, and is, in some cases, twice as powerful. I have used digestive enzymes for about three years now and the results have been better digestion and fewer digestive problems. The only drawback to this formula is that certain enzymes in the formula are not enteric coated to ensure survival of the enzymes in the acid environment of the stomach. However, newer research suggests enzymes inactivated in the stomach are often reactivated in the intestine.
