Energy Supplements

Does anyone take drink coffee or take an energy supplement to workout? I take 1/3 of a 5 hour energy each morning and it has L phenylalanine. Is that bad to take even in such small amounts?

Phenylalanine interferes with absorption of L-dopa. Also energy drinks are high in sugar which can be harmful to your gut health. If you click on the phenylalanine box above, there are links to other posts.
