What is in your Pao pereira product?

By Sylvie Beljanski

The Beljanski Foundation has fostered a great deal of research utilizing specific alkaloids found in the bark and leaves of certain plants. Among them, flavopereirine, an alkaloid found in the bark of Pao pereira (formerly known as PB-100), has been found, through research, to combat the proliferation of cancer cells. The Beljanski Foundation’s research has shown that the greater the potency of this alkaloid, the greater the benefit.

At The Beljanski Foundation, we want to use only the highest concentration of Pao pereira. That is why we had an independent lab conduct analysis of several Pao pereira  products and their concentration of Flavopereirine (the key alkaloid in Pao pereira) to source the best.

Therefore, a project was undertaken to compare a number of dietary supplements available worldwide that contain and advertise Pao pereira.

Comparison of various dietary supplements containing Pao pereira:

The Beljanski Foundation procured nine samples of dietary supplements from the United States and Europe for comparison. The objective was to compare the levels of flavopereirine to see if the beneficial compound in the products were similar in content across several brands. The nine intact, sealed bottles, were submitted to the same independent laboratory for analysis. The test method used, High Performance Liquid Chromatography (HPLC), was the same for all samples tested. The unused portions of the samples were returned to The Beljanski Foundation to be examined visually. All samples were found to be intact and not discolored or damaged.

The results of the testing were quite dramatic in regard to the flavopereirine content in each sample. Among the nine samples tested, ranging from almost nothing – to high quality.

Here are the results:

The results from the independent laboratory were graphed to clearly show the vast difference in Pao pereira products sold on the market


Most products advertised as Pao pereira products have in fact very limited amounts of flavopereirine with the exception of two Natural Source International, Ltd. products.

While The Beljanski Foundation cannot offer a definite reason for the drastic differences in flavopereirine content in the various products tested, it is most likely that there are differences in the manufacturing processes or in the materials used for production.

The research programs of The Beljanski Foundation have all been conducted with materials supplied by Natural Source International, Ltd., a company with principles based on quality and integrity, and also the only company respecting the extraction methods and the quality defined by Mirko Beljanski himself.

To sum things up

Knowing what’s actually in your supplements is often a challenge. There may be a less expensive version but there is a reason it is less expensive and when you are dealing with your health you should not have to worry about the quality of what you are putting in your body.

This is a living document

If you come across other products claiming to be Pao pereira extracts let The Beljanski Foundation know.
We will source the product, have it independently tested an published the results.

The Beljasnki Foundation is an independent reference for the quality of the products stemming from the research of Mirko Beljanski.
