                                According to the Food and Drug Administration (FDA), artificial hormones are not added directly into milk during processing. However, some conventional dairy cows are treated with a synthetic hormone called recombinant bovine somatotropin (rBST), which can lead to higher levels of certain natural hormones in their milk. This has led to consumer interest and confusion about whether milk sold in the grocery store contains added hormones, and what it means for your health.
