Only phosphatidic acid from soya speeds up muscle growth
A daily dose of 750 mg phosphatidic acid helps strength athletes build up strength and muscle mass faster. Sports scientists at the University of Tampa come to this conclusion in a sponsored study.

Effects
An asterisk (*) represents a significant effect in terms of the training period ('before' versus 'after') and a number sign (#) represents a statistically significant effect derived from phosphatidic acid versus the placebo treatment. Phosphatidic acid led to an extra increase in lean body mass and muscle strength.
Mechanism
S-PS = soy-derived phosphatidylserine; S-PI = soy-derived phosphatidylinositol; S-PE = soy-derived phosphatidyl-ethanolamine; S-PC = soy-derived phosphatidylcholine; S-PA = soy-derived phosphatidic acid; S-LPA = soy-derived lysophosphatidic acid; DAG = diacylglycerol; G3P = glycerol-3-phosphate; E-PA = egg-derived phosphatidic acid.
As you can see, phosphatidylserine, lysophosphatidic acid and phosphatidic acid from soya are mTOR boosters, while phosphatidic acid derived from eggs has little effect.
"This could be due to the composition of the phosphatidic acid molecule", the researchers suspect. "For instance, Foster et al. have reported differing effects of phosphatidic acid based upon the structure of its fatty acid components; wherein, two saturated fatty acids promoted storage, yet one saturated and one unsaturated fatty acid promoted signaling."
"Thus, the higher unsaturated fat content of soy may explain these observations. This suggests that soy derived phosphatidic acid, lysophosphatidic acid, and phosphatidylserine are superior agonists of mTOR signaling, and therefore, they appear to be suitable candidates for augmenting the effects of resistance training on muscle mass."
