Highly recommend
It’s a very good product, same as all other GNC products I’ve used. The B vitamins and caffeine really give you a boost of energy. After taking daily for a few weeks I noticed more mental clarity, and after a few months I noticed somewhat sharper vision. Definitely take with food as directed.

Excellent Product that performs as advertised. Highly recommend for active lifestyles. Keyword-SPORT
As a personal trainer and retired Marine this product exceeds my demands. It clearly fulfills it's purpose as a SPORT DAILY Multivitamin with the added bonus of caffeine and beta-alanine. If one READS the label, something I highly recommend before ingesting anything, it clearly states what is in this particular product. GNC offers alternatives to the Sport One Daily located on the same shelf so do your research. Overall excellent product that performs as advertised.
