Consuming 25g of potato protein isolate twice daily (totaling 1.6g protein/kg/day) stimulates muscle protein synthesis at rest and further augments it when combined with resistance exercise in young women.

If you are a young woman looking to build muscle, consuming 25g of potato protein isolate twice a day (totaling 1.6g of protein per kg of body weight) will stimulate muscle growth even when you are not exercising. Adding resistance exercise will boost this effect further. This makes potato protein a viable, high-quality alternative to animal-based proteins for muscle building.

GoodSupportsHIGH confidence
Ingestion of PP stimulated MPS by 0.14 ± 0.09 %/d at Rest, and by 0.32 ± 0.14 %/d in the Exercise limb... Consuming PP to increase protein intake to levels twice the recommended dietary allowance for protein augmented rates of MPS.

Why this rating

Randomized controlled trial with a parallel-group design, though limited by a small sample size (n=24) and short duration (14 days).
