Pao pereira tree (Pau pereira / Geissospermum) and Beljanski research

Pao pereira tree (Pau pereira / Geissospermum vellosii) Pao pereira bark was studied by Mirko Beljanski at the Pasteur Institute

Victim of its success, Natural Source International’s Pao pereira formula prepared according to Professor Beljanski’s proprietary extraction processes, has sparked several companies interest in the field of dietary supplements, especially in Europe for several years. Those companies are advertising new products made of “Pao”, claiming to have the same proprietary benefits than Beljanski’s formulation, quoting even his name to promote them.

Are those products as good as the Beljanski® products?

To answer this question objectively, The Beljanski Foundation ordered anonymously those products from various companies selling them across Europe (Luxembourg, Belgium, Spain…) including Natural Source International. All the products were stored, analyzed under identical conditions and evaluated by a certified laboratory specialized in quality control. To analyze those products, the laboratory used high-performance liquid chromatography (HPLC), a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. Here, it was to reveal in each of the products, the presence and amount of Flavopereirine, the active compound in Pao Pereira. The results revealed that the concentration of Flavopereirine used in the products sold by these companies was far inferior to the one used by Mirko Beljanski when conducting his research except for Natural Source International, which is the only company who conducts a correct extraction of the active ingredient to provide the necessary concentration.

These companies provide products claiming to have the same properties than the Beljanski® products when obviously the analyses showed the opposite.

While this practice has been known in Europe for a few years, it is a relatively recent phenomenon in the US. Again The Beljanski Foundation asked an independent and certified laboratory to analyze two new products distributed in the US market by a pharmacy located in Miami (Rainforest Pharmacy). The first one, in liquid form, contained a very low concentration of Flavopereirine, 90% less than in Beljanski’s formulation. In the second product, in capsules form, Flavopereirine was not even detectable.

It appears that those two products were made of Pao pereira leaves unlike the Beljanski® products made of Pao bark, which may explain the significant differences in terms of Flavopereirine concentration. If these leaf extracts may have some interest, it is not reported on their packaging. But one thing is sure: they cannot be compared to Beljanski’s formulation, and should not claim to have the same properties and effect.
