Vitalzym contains, among others, serrapeptase, papain and bromelain. These are protelytic enzymes
derived from biological sources. Serrapeptase was originally isolated from silkworms but now is commercially produced from genetically modified bacteria. Papain is derived from papaya and bromelain is an extract of pineapple root.
Although long used to aid in the digestion of proteins all of these also act as soft tissue anti-inflammatories. I use bromelain and serrapeptase but primarily for my sinusitis. When taken without food they break down think mucus produced in inflammed sinuses - they work great for me.
As for anti-inflammatory activity in muscles and tendons I find that curcumin, an extract of the curry spice turmeric to be *really* effective. It had substantially reduced pain I've had for years in the tendons in my hands, elbows and feet. Curcumin has no side effects under taken in extremely large quantities in which case
it may loosen the bowels somewhat. It also has many other beneficial long term effects.
There's good info on curcumin here: http://www.whfoods.com/genpage.php?tname=foodspice&dbid=78
I have found clinical studies that verify practically all of the claims for curcumin.
Hope the above helps...
By the way, both serrapeptase and bromelain are approved for use in some European countries, notably Germany for medical use, mainly for prevention of post-surgical inflammation.
