Soybean carbohydrate improved blood vessel function in aged mice

In 20-month-old mice, 12 weeks of supplementation restored blood vessel relaxation controlled by the vessel lining and reduced signs of inflammation.In 20-month-old mice, 12 weeks of supplementation restored blood vessel relaxation controlled by the vessel lining and reduced signs of inflammation.
