• Relief from hot flashes*
• Helps manage mood & energy swings*
• Helps alleviate night sweats & promotes restful sleep*

Best EstroG-100 features a patented, clinically proven blend of three herbal extracts that together offer relief for uncomfortable feelings associated with menopause.* Research has shown this combination to promote healthy management of hot flashes, night sweats, nervous irritability, dizzy spells, vaginal dryness, numbness and tingling, occasional emotional discontent, and occasional fatigue and sleeplessness.* Unlike some common menopause formulations with ingredients that bring safety concerns, EstroG-100 has a track record of safety, and the herbs in it have a long history of use in Asia.*

About two-thirds of women develop uncomfortable feelings prior to, during, or after menopause.9 Sleep disruptions, nervous tension, sadness, occasional fatigue, and vasomotor discomforts (hot flashes/cold sweats) are all commonly reported by women. EstroG-100® may help cope with such menopause-related discomforts.

EstroG-100® was tested on pre-, peri-, and post- menopausal American women in a randomized, double blind, placebo-controlled trial. The 64 participants took either 514 mg of EstroG-100® or a placebo tablet every day for 12 weeks.10 To be eligible for the study, women had to have moderate or severe menopausal discomforts as identified by the Kupperman menopausal index (KMI), a questionnaire that measures changes in uncomfortable feelings associated with menopause. Potential benefits were assessed by KMI questionnaires at 6 weeks and at 12 weeks. The KMI evaluates a number of menopausal parameters, including hot flashes/cold sweats, paresthesia (numbness and tingling), sleep interferences, nervousness, melancholia (sadness or gloom), vertigo (dizzy spells), occasional fatigue/weakness, palpitation (pounding of the heart), formication (sensation of crawling of the skin) and muscle or joint discomforts. A separate questionnaire assessed changes in vaginal dryness.

By the end of the study, the average KMI score was significantly lower (indicating improvement) in the EstroG-100® group, compared to the placebo group. Vaginal dryness was also significantly improved in the EstroG-100® group. The individual KMI scores that improved (compared to the control group) were hot flashes/cold sweats, paresthesia, sleep interferences, nervousness, melancholia, vertigo, occasional fatigue/weakness and muscle or joint discomfort. The EstroG-100® group had no major adverse effects. Importantly, this group showed no increase in estrogen or follicle stimulating hormone (FSH) levels. Researchers attributed these impressive benefits to the diverse bioactivity of the non-estrogenic compounds in the three plants that make up EstroG-100®.

Previous research on EstroG-100® was conducted in Korea, where for centuries these three plants have been traditionally used to promote health. In a randomized, double blind, placebo-controlled trial of 48 perimenopausal women, half were given capsules containing a combination of the herbs in EstroG-100® as the major ingredient (also in the capsules were amino acids, vitamins & minerals, and soy).11 After 3 months, there was significantly greater improvement in this group over the placebo group. These researchers subsequently reported that in vitro (in an experimental culture system) extracts of all three plants showed estrogen-regulating activity.12 Furthermore, the mixture of all three showed greater activity than individual extracts, which suggested potential synergistic activity of the three herbs of EstroG-100®.


The Best Choice

Several other dietary supplement ingredients have been researched for their potential to help alleviate discomforts associated with menopause/perimenopause. Unfortunately, these results have been mixed—ingredients that may by useful for one type of menopausal discomfort may not offer support for others.9,13 EstroG-100®, in contrast, shows evidence of benefit for numerous menopause/ perimenopause discomforts, as well as for vaginal dryness.
