The image of 3 tennis courts helps us to understand the enormous surface area presented by as little as 500 mg Renaltec®.
A tennis court is about 23 m long and 11 m wide so its area is about 260 m². Three tennis courts have a total surface area of about 750 m².
The manufacture of Renaltec® is an extremely complex process; the surface area in the balls is greatly enlarged by creating a system of channels inside them. This makes them into thoroughly porous balls with a great deal of internal branching. The total pore volume and what is known as the inner surface area are measured during quality control after Renaltec® has been produced. The inner surface area is the area available to adsorb substances such as indole.
Renaltec® has a surface area of about 1500 m²/g. Our daily dose of 500 mg, or half a gram, is where the image of the tennis courts (= 750 m²) comes from. This image is easier for most people to understand than the number alone.
The enormous surface area for adsorption is just ONE of the important properties ensuring the effectiveness of Renaltec®. Other, equally important, properties are the small pore size of 2 nm (selectivity), the charge on the inside of the micro channels in a Renaltec® ball and the smooth exterior enabling the ball to “roll” through the GI tract. It is the combined action of all these properties that makes Porus® One such an exceptional product.
