Title: I noticed no effect from using this supplement
Review: Figured I'd try DL-Phenylalanine since I was feeling a bit lethargic and this product is supposed to "support an alert state" as well as reduce pain and help with memory. Well, I felt none of these benefits. I think taking vitamins B12 or a B complex are actually better, add a cup of coffee and you're good to go.
Is this product review negative?
