Does anyone take them before bed as well?

I do. My reading leads me to believe this: They are the amino acids which cannot be synthesized by the body. BCAA's supplement the protein already in your body, making more of it "complete" and available to build tissue. It isn't so much WHEN, but that there's a steady stream available.
