A small study at the Stanford University School of Medicine tested the nutritional supplement known as "Fertility Blend" and found evidence to suggest that it may be effective in helping some women conceive. In a study of 30 volunteers, half the women took Fertility Blend 3 times a day and the other half took placebo. While none of the women in the placebo group conceived, 5 of the women in the supplement group became pregnant within 5 months and 4 went on to deliver healthy babies.
Researcher Lynn Westphal, MD, who reported her results the Journal of Reproductive Medicine (April 2004), said that if a larger study yielded similar results, then this supplement could give women another option before seeking in vitro fertilization. Among the ingredients in Fertility Blend is chasteberry, which has demonstrated improvement in ovulation and may restore progesterone balance. It is an amino acid that improves circulation to the reproductive organs.
