🏋️ Is Soy Milk Suitable for Muscle Growth?

🧪 What the Science Says:

“Soy protein supplementation is effective at increasing lean body mass in response to resistance training in both men and women.”
— Messina et al., Nutrients (2010)

“Ingesting 20–30g of soy protein post-exercise can stimulate muscle protein synthesis similarly to whey.”
— Phillips et al., Applied Physiology, Nutrition, and Metabolism (2011)

🏁 Verdict:

✅ Yes, soy milk is a solid plant-based option for muscle gain, particularly when combined with strength training and adequate protein intake. While whey may offer a slight edge in MPS, soy remains the best vegan-friendly milk alternative for muscle-building purposes.
