Phosphatidic acid (PA) is a phospholipid that is naturally found in the human body and in certain foods such as soybeans and egg yolks. PA is involved in various cellular functions, including cell signaling, membrane structure, and lipid metabolism.
In protein powders, PA is commonly used as a supplement to promote muscle growth and improve athletic performance. Studies have shown that PA can stimulate the mTOR signaling pathway, which plays a crucial role in muscle protein synthesis. This can lead to increased muscle hypertrophy, strength, and power.
PA has also been shown to have other potential health benefits, including improving insulin sensitivity and reducing muscle damage and inflammation associated with exercise. However, more research is needed to fully understand these effects.
Phosphatidic acid is generally considered safe for consumption.
