Vyvanse and d spastic acid

[Robbie Balboa]

So I am prescribed vyvanse for ADHD. I occasionally use it as a preworkout. My question is, would the addition of d aspartic acid lower the effect of vyvanse since it is acidic?

No; you need to avoid hydroxy acids like citric acid (in citrus fruits that mess with amphetamine's absorption). DAA is a dicarboxylic acid. They're different classifications.
