Estroven® Safety
Estroven® has been on the market since late 1997, and all of its ingredients have been studied carefully based on the best scientific information available. There are no significant side effects associated with the recommended dosages of Estroven®.
Safety of Estroven's Formula
Estroven® products were tested to develop safety profiles. The tests were standard FDA-type toxicology studies. In these tests, very high doses of the Estroven® formula were used, and there were no significant adverse events or health problems. There were no negative effects — even at very high doses — on blood and on the thickness of the lining of the uterus, nor were there any uterine or cellular changes. Also, the clinical studies found no side effects from taking the individual ingredients that make up Estroven® products.
Before Estroven® was offered for sale to the general public, the Estroven® formula was given to nearly 300 women as part of an in-home usage test. The vast majority of these women who took Estroven® reported that the supplement "met or exceeded their expectations" based on their individual needs and experiences. Over the years, with tens of millions of Estroven® products sold, there have been very few consumer complaints, and none showing a causal connection between Estroven® and any significant negative health event. This confidence in the Estroven® suite of products, combined with the supporting science on the ingredients and our own toxicological reports, allow us to say that Estroven® products are safe.
Every batch of Estroven® produced undergoes extensive purity and potency testing. These tests are performed by qualified laboratories, which follow standards set by various scientific agencies, including the Food and Drug Administration (FDA), U.S. Pharmacopeia (USP), NSF, AOAC, and other standard-setting authorities. Estroven® formulas are also tested for shelf-life stability to be sure that the products will be as effective when you buy them as they were when they left the plant.
Safety of Estroven's Ingredients
The two primary ingredients in our products — isoflavones and black cohosh — have long and safe histories of use. A well-known and well-reputed vendor, Archer Daniels Midland Company, supplies the soy isoflavones used in our formula. In addition, there have been a number of clinical studies about the safety of isoflavones, as well as their positive and protective effects on cardiovascular and bone health.
There has been much safety research done on black cohosh. It is important to note that the kind of black cohosh used in Estroven® products is cimicifuga racemosa, the actual North American herb, rather than the Asian variety, which may not have the same degree of purity. Also, black cohosh does not have the same action in the body as estrogen, which means that it can be used by women who cannot take synthetic estrogens.
Other ingredients used in Estroven® include vitamins and minerals, all of which fall below the Safe Upper Limits as defined by the federal government, as well as various other herbs, which have a similar safety profile to isoflavones and black cohosh.
Using Estroven® with Synthetic Hormones
Estroven® contains phytoestrogens, or isoflavones, natural substances that can be taken safely with hormone replacement therapy (HRT). Phytoestrogens work with your body to support hormonal balance naturally, gently, and safely. Please consult your healthcare professional before taking Estroven® products with HRT.
Using Estroven® with Other Prescription Medicines
Although there are no known significant side effects associated with the recommended use of Estroven® with prescription medications, your medical history plays an important role in the effect that supplements have on your body. Please contact your healthcare professional before using Estroven® with other prescription medicines.
Potential Allergens in the Estroven® Formula
Estroven® does not contain artificial dyes, colors, preservatives, flavors, yeast, wheat, gluten, lactose, or animal products. Estroven® does contain soy, and a small percentage (about 3%) of the population is allergic to soy. Please consult your healthcare professional before taking Estroven® if you have any known allergies.
As with any nutritional supplement, please consult your healthcare professional before taking Estroven®.
