How is IsoRel different from other soy isoflavone supplements?
IsoRel is produced from 100% whole soybean extract, which means that each capsule provides naturally occurring soy isoflavones (genistin, daidzin, and glycitin) in the same isoflavone ratio as found in soybeans. IsoRel provides 100 mg of soy isoflavones in only one small capsule per day.
Does IsoRel have side effects?
Although there are no expected side effects from IsoRel, a small percentage of individuals may experience gastrointestinal upset (constipation, diarrhea, bloating, or nausea).
Is there anyone who should not take IsoRel?
Yes. Do not take IsoRel if you are allergic or sensitive to soy and speak to your healthcare provider if you have a history of estrogen-positive breast cancer.
