Why is Sheep Placenta with Lycopene only widely available now if the health benefits have been known about for nearly 100 years?

The development of Live Cell Therapy has been developed over the years. However, Sheep Placenta was only available in injection form which made it an expensive therapy. Bio-technology has made it possible to extract the Sheep Placenta and keep the ingredients active in gel-capsules. This has reduced costs and opened up availability.
