Vitalzym is an enzymatic supplement. Enzymes are proteins present in the body to break down compounds that the body no longer has a need for. They are present in almost every biological reaction. As a result, proper enzyme levels are needed to eliminate toxins and to prevent build up of fats, proteins and other waste products within the body.

Vitalzym Direct Effects

According to the manufacturer and various sites that sell this supplement, Vitalzym is a completely natural product. The active ingredients are all enzymes and, because these enzymes naturally occur in the body and are present in the digestive tract, Vitalzym causes no side effects directly. The other main ingredients are maltodextrin, silicon dioxide and magnesium stearate, and are all used to either protect the active enzymes or to help keep them in tablet form until it reaches the intestines. The product also is not made with any gluten or lactose products and, as a result, should not cause any allergies.

Indirect Side Effects

Vitalzym is designed to supplement the body's enzymes and to aid in "detoxification". Detoxification can cause certain symptoms to appear; however, the most common detox side effect is softer stools and more frequent bowel movements. Other side effects include headaches and nausea or certain flu-like symptoms, such as aches and chills. Urine may also develop a distinct odor and a rash may appear on the skin (the location of the rash varies from person to person). (which is supervised by Medline and the NIH) also warns that detoxification can lead to diarrhea, dehydration, imbalances in minerals and problems with the digestive system.


One of the dangers of Vitalzym is that some of the enzymes that it contains can thin the blood. As a result, it can cause heavier than normal bleeding in women who are menstruating. According to Dr. Wong of, women who are taking VItalzym to shrink their fibroids also run the risk of surges in estrogen, which can also increase menstrual bleeding. Vitalzym's action as a blood thinner is especially serious for people who are already taking blood thinning medication or for patients with coagulation problems.
