Glass Bottles

• No plastic to outgass into the product
• Progesterone Cream contains water
• Oxygen in the water can also oxidize Progesterone

• Progestelle Oil contains NO Water to oxidize the progesterone for a longer shelf life, a year or more

We use glass bottles because plastic has the potential to outgass into the product.  Oxygen breaks down and oxidizes progesterone.  Progesterone Creams contain water.  Water also contains oxygen.  This oxygen has the potential to degrade the progesterone.  Plastic is also semi permeable to oxygen in the atmosphere.  However, Progestelle does not contain water.  Progestelle uses a glass bottle, not plastic.  Oxygen has a smaller chance of degrading the Bioidentical Natural Progesterone in Progestelle.
