Synthetic Progesterone Warning Label
Ona's Natural Progesterone is in compliance with California's Proposition 65 law which lumps natural progesterone together with its many synthetic forms, known as progestins.
Because synthetic progestins have been found to be dangerous and are only available by prescription, the law requires a cancer warning on each of the product labels regardless if they are natural or not.
Ona's Natural Progesterone is not synthetic, and is safe, effective, and available over-the-counter.
Avoid contact with eyes. For external use only. Discontinue use on any area that is affected negatively.
