Swanson Standardized Soy Isoflavones 750 mg, 120 Capsules

What is Swanson Standardized Soy Isoflavones?

Swanson Standardized Soy Isoflavones is a dietary supplement in capsules that provides 75 mg of SoyLife complex per capsule, standardized to 1.8% isoflavones. Each container holds 120 capsules, formulated to offer a concentrated supply of soy isoflavones, plant compounds that have been studied for their role in women's health, especially during menopause.

Soy (Glycine max) is a legume rich in isoflavones such as genistein and daidzein, which act as phytoestrogens. This product uses the exclusive SoyLife complex, which preserves the natural matrix of soy for optimal bioavailability. These substances may help mitigate some of the changes associated with declining estrogen during menopause, although the EFSA has only approved a specific claim for bone health.

Science-backed Benefits

Soy isoflavones have a health claim authorized by the EFSA: "Soy isoflavones contribute to the maintenance of bone mineral density in postmenopausal women"*. This effect is produced thanks to their ability to modulate the activity of osteoclasts and osteoblasts, helping to preserve the strength of the skeletal system. To obtain this benefit, a daily intake of 40-60 mg of isoflavones is recommended. Since this supplement provides 1.35 mg per capsule, it can be combined with soy-rich foods (tofu, soy drink) to reach the effective dose.

Furthermore, including soy isoflavones in the diet can contribute to a balanced diet that supports cardiovascular health. Although there is no specific health claim for the heart, soy-rich dietary patterns are associated with healthy cholesterol levels. The SoyLife complex also preserves other soy nutrients, such as proteins and saponins, which provide nutritional value.

*The health claim is authorized by the European Commission (EU Regulation 432/2012).
