Royal Jelly is a highly natural nutritional complexity food. Common bees take Royal Jelly in the first 3 days only, and then take pollen and honey after that, they live only 1 ~6 months. But the queen bees live 5 ~8 years and lay approximately 2,000 eggs a day because they take Royal Jelly all their lives. And this proves Royal Jelly can improve fertility and enhance longevity. People believe this product will do as much for humans as it does for bees.
Scientific analyses show that Royal Jelly contains high levels of vitamins D and E, it’s rich in amino acids, sugars, lipids, multi-vitamins, and most importantly, proteins, also it has ample levels of iron and calcium. All of these are essential to maintain and improve proper health and organ function, it is very clear to see how Royal Jelly can help with in assisting with fertility and longevity. My personal idea is that Royal Jelly + physical exercise like swimming and running would be doubtless a great help in improving your sex ability and longevity, especially for the aged.
Y.S. is a very good and reliable provider of bees product in USA. I bought lots of its product including Royal Jelly. Below is the Y.S. Royal Jelly I bought, mixed with pollen and propolis. Before I had pure Royal Jelly and it irritated my stomach, but I found Y.S. Royal Jelly mixed with pollen was mild to my stomach.
