Young Living is forced by California law to include this warning on its bottle.
We appreciate your concern regarding California’s Proposition 65 warnings which are legally required to be on our Progessence Plus product. Proposition 65 requires that products sold in California which carry any ingredients deemed to the California legislature to be hazardous to health must carry the warning you see on our label.
In the case of Progessence Plus, California requires the warning on all progesterone-containing products. However, California law does not distinguish between the synthetic medroxyprogesterone which is the cause of California’s concern, and the natural progesterone which we derive from yams and which are widely used in the health industry. Both are generically referred to as “progesterone,” which is the ingredient name in California’s list. If you would like further information on this topic, we recommend you contact your healthcare professional for further information.
