There is just so much confusing information out there when it comes to supplements, nutrition, technology and skincare. I can't begin to attack it all in one post.
Our cells are wired to protect themselves from viruses and invaders in addition to transporting nutrients. As we age the cells get stubborn and crankier and don't want to allow ANYTHING to pass through the membrane, the protective outer layer. The video above gives a very simple, yet complex demonstration of how nutrients get into the cells.
When I was formulating an oral anti-aging product, the labs and manufacturers told me the maximum percentage of a vitamin that could be absorbed is about 10-30%. There are so many factors why. Enzymes, available glucose, particle sizes and much, much more. I will be able to surpass these issues with technology in the future if P&G would take me on (hint. hint).
When it comes to skincare most of the particle sizes are too large to absorb. I demonstrate this in an old video from years ago below.
Finally please make sure you check out
this blog entry about Vitamins in Food versus Vitamins in Pills by Ron Lagerquist before you buy your next supplement. I also included the video below so you could learn more about studies done with popular supplements through the years and get some good sleep since it can be a bit dry to listen to.
