Prolactin is a hormone that is associated with lactation (breast-feeding). In fact, for a nursing mother, the sucking of the infant releases prolactin, filling her breast with milk. Even during pregnancy, the levels of prolactin are increased, which causes enlargement of the breasts in preparation for breast-feeding.

High levels of prolactin are also responsible for increased sexual satisfaction. They can suppress the normal ovarian cycle, however. Too much prolactin is associated with hypothyroidism, emotional stress and can cause erectile dysfunction in males. In these situations, natural ways to lower prolactin can be utilized.

Testing Prolactin Levels

If you suspect your prolactin level is too high, you can have this tested by your physician. You will get a simple blood test. Physicians will often order a prolactin test when a pituitary tumor is suspected. Other results of high prolactin levels may include infertility, irregular menstrual cycles or breast milk production unrelated to child birth.

Take Vitex (Chasteberry)

Taking Vitex (or Chasteberry) will help to naturally lower your prolactin levels. This can be taken in a pill or in drops. It has been shown to be effective in treating infertility and irregular menstrual cycles. Vitex takes a while to build up in your body, so you will have to take it for up to 18 months to see the results. Take 1,000 mg of Vitex two or three times a day for best results.

Other Herbs and Vitamins

Vitamin tablets

Start taking B complex and Vitamin E regularly. Take the standard recommended adult daily dosage on the bottle you purchase.

Purchase minerals Bromine Iodine and Silicon Sulphur and begin to take a tablet of each once a day. Also, get the herbal supplements licorice root, ginger, cayenne and golden seal; take one caplet of each twice a day. These can all be obtained at a local health food store or online. All are supposed to lower prolactin levels over time in both men and women. Do not expect instant results. You may have to take them for a few months to a year before you see a change.

Consult your physician before taking any dietary supplements.
