Fenugreek
Fenugreek is a herb that is often used by nursing mothers to increase their supply of breastmilk.The most common reasons for low milk supply are illness, fatigue, stress and returning to work. Often a decrease in supply is temporary but if you need a boost Fenugreek may help you. Although Fenugreek has been used for centuries by lactating mothers to increase milk supply its use in the United States is more recent and there are no controlled studies available about its use.

Fenugreek seeds


Fenugreek capsules containing ground seeds can be purchased from most health food stores. Capsules typically contain either
580 or 610 mg. A bottle of 100 capsules costs about $6 - $8. Some health food stores and food co-ops sell the capsules in
bulk form. Fenugreek tea can be used, but teas are considered less potent than capsules. Fenugreek tea has a somewhat
unpleasant bitter taste.

The Food and Drug Administration (FDA) provides only general guidelines on natural herbs, and fenugreek is included in
FDA's list of herbs generally regarded as safe. There has been no formal research on fenugreek, but an increasing amount of
observational and anecdotal evidence points to its efficacy. Because Fenugreek may be a uterine stimulant, however, it should
be avoided during pregnancy.
