Lignans Shown to Reduce Hot Flash Frequency

Hot flashes are an unfortunate and uncomfortable result of the hormone shifts that occur during menopause and treatments are very limited. A recent study has found that taking a supplement of plant lignans that come from the Norway spruce could reduce the number of hot flashes in menopausal women by more than 50%.

Participants in the study included 22 postmenopausal women who were still experiencing hot flashes and not taking hormone replacement therapy to treat it. Over the course of eight weeks, those women took either 36 mg or 72 mg per day of the lignan supplement.

At the conclusion of the study, the researchers noted a 44% reduction in frequency of hot flashes in the low dose group and a 50% reduction in the high dose group. An even greater effect was seen on the frequency of severe hot flashes, which were reduced by 80% in the high dose group.

Researchers from Medicus Research conducted the study. It was published online ahead of print on December 10, 2013, in the Journal of the American College of Nutrition.

Lignans have been linked with many other health benefits, including preventing prostate cancer, preventing osteoporosis, improving brain function, preventing cardiovascular disease, improving immune function, reducing inflammation, and aiding reproduction.

If you are looking to increase your lignan intake, flaxseed has by far the highest lignan content of any food. You can also get more lignans in your diet through sesame seeds, sunflower seeds, broccoli and kale.
