We have revolutionized the concept of healthy proteins.

Protein is essential for life and for muscle growth and maintenance. However, some types of protein can increase levels of pro-aging hormones like IGF-1, and many protein products contain additives that can compromise your health. The L-Protein Bar is different.
Formulated by longevity scientists behind the Prolon 5-Day Fasting Mimicking Diet (FMD), this bar provides clean, complete plant-based protein that nourishes your strength and vitality, without the additives that promote aging.
