Pao pereira comparative study

Knowing what is actually in your supplements is often a challenge. There may be a less expensive version but there is a reason it is less expensive. 

Don’t be fooled by low cost products that offer just a fraction of the extract you need. There can be a huge difference in concentrations between various extracts available on the market, as shown in a comparative study conducted by an independent laboratory commissioned by The Beljanski Foundation.

The Beljanski Foundation is often contacted by people looking for guidance to buy the right extracts as per Mirko Beljanski’s specifications. Therefore, The Beljanski Foundation purchased several products available on the market advertised as Pao pereira products, to measure their concentration in flavopereirine (the key alkaloid in Pao pereira). All the Pao pereira products were analyzed anonymously by an independent lab and tested using the same techniques.

Natural Source International dramatically surpassed all of its competitors. That’s why reputable research entities choose Natural Source International’s products for their research.
