In the case of natural supplements, it is important to first understand why we feel strongly about transdermal delivery - absorbing nutrients  through the skin.

Doctors around the world are calling transdermal delivery "the delivery system of the future."  It has been discovered that a high absorption rate of many supplements can be achieved when delivered through the skin - usually as a cream. (The physical size of the supplement's molecule plays an important role).  The reason for this is when supplements are delivered transdermally, they go directly to the blood-stream, initially bypassing the liver.  The result can mean as much as 95% of the supplements get to the cells where they are needed.*

Conversely, studies have shown when some substances are taken orally, as little as 5% make it to the cells where they are needed.  This is because of the stomach, liver and digestive system excreting and discarding much of them. 

Think about that for a moment 95% vs. 5%.  This is why we believe transdermal delivery can be a much more effective alternative for many supplements.
