Summary

This product consists solely of soy protein isolate, which is a highly processed form of soy. While it provides a high protein content, the amino acid profile is less optimal compared to animal-based proteins, and there are concerns about phytoestrogens affecting hormone balance. The minimal ingredient list is a positive aspect, but the processing level and potential hormonal concerns slightly reduce its overall rating.
