We've all seen the new study on D-AA and the subsequent bunch of anti-supplement bloggers talking about how it doesn't work.
What most people probably didn't notice is a key difference between the material used in the two studies that show it does work:
D-Aspartate, A key element for the Improvement of Sperm Quality
The role and molecular mechanism of D-aspartic acid in the release and synthesis of LH and testosterone in humans and rats
And the one showing it does not:
D-Aspartic Acid supplementatoin combined with 28 days of heavy resistance training has no effect on body composition, muscle strength, and serum hormones associated with the hypothalamo-pituitary-gonadal axis in resistance trained men.
That difference being?
The studies in favor of DAA are using chelated Sodium DAA
Baylor only used straight DAA for their study
Why does this matter?
Because D-AA on its own without a mineral chelate has horrible bioavailability.
A quick survey of the nutraplanet store shows the following awesome companies that are selling the right type of DAA:
SNS DAA
E-Pharm TestForce
AI Sports DAA
Purus D-Pol
A few brands that are selling inferior DAA:
USPLabs DAA3K
SS DAA
NP Bulk DAA
