Soy protein supplementation reduces exercise-induced metabolic biomarkers such as triglycerides, uric acid, and lactate, and improves antioxidant status compared to whey protein in long-term studies.
Soy protein is not just about muscle; it actively helps your body handle oxidative stress and metabolic strain from exercise. It reduces lactate, uric acid, and triglycerides more effectively than some other sources. This makes it a smart choice for overall metabolic health alongside muscle building.
SP consumption promoted the reduction of exercise-induced metabolic/blood circulating biomarkers such as triglycerides, uric acid and lactate. Better antioxidant capacity against oxidative stress has been seen with respect to whey protein in long-term studies.
Why this rating
Based on systematic review of multiple RCTs showing consistent reduction in biomarkers and antioxidant benefits.
