When you boil an egg, you have the  clear film lining eggshells. This is Eggshell Membrane. Our Eggshell Membranbe powder is branded by Eggbrane. Read more about it on Eggbrane.com.

Native Eggshell Membrane is the same as Undenatured Eggshell Membrane. Native / undenatured Eggshell Membrane is in it’s original and bioactive form. 

It is different and not the same as hydrolyzed Eggshell Membrane Collagen, which is enzymatically hydrolysed en treated with heat. Heat destroys many of the important micronutritients

Collagen Type I is the most common collagen in the body and in mainly found in hair, skin and connective tissue.

Type V collagen is essential for the fibrillation of Type I & III collagen and tissue quality. 

Type V collagen contributes to the bone matrix, corneal stroma, and the interstitial matrix of muscles, liver, lungs, and placenta.

*KLAUS VON DER MARK, in Dynamics of Bone and Cartilage Metabolism (Second Edition), 2006

Vitamin C contributes to the normal development of collagen for the function of bones and cartilage.

Hyaluronic acid is the main component of the synovial fluid and is also found in cartilage. The Synovial Fluid prevents the cartilage surfaces from rubbing against each other. With increased stress on the joint and with increasing age, the viscosity (lubricity) of the synovial fluid changes. Due to its enormous capacity to store water, hyaluronic acid is partly responsible for keeping the cartilage elastic and flexible. We only use low molecular weight hyaluronic acid for our products.

In our factory in Groenlo, the Netherlands, we collect the eggshell membranes and process them through our patented production technology. Our unique extraction technology allowes us to extract ingredients at a low ambient temperature. This leaves us with the ingredients being in their original & biologically active shape.

For the best possible results, permanent usage is generally recommended. The recommendation is based on comfirmed values and on scientific studies of Eggshell Membrane powder.
