Cellucor – C4 Smart Energy RTD – Product Overview

C4 pops out another offspring in RTD for under the newly minted Smart Energy trademark. This time Cellucor has decided to foregot the bicep and abs shots and shoot for those dedicated to getting their brain and energy levels properly in gear each day or for a specific task.

Offering a few nootropic type ingredients over the more common pump, taurine, and mega dose caffeine type formulas from everyone else, they add the ever increasing researched Cognizin CDP choline at ~250mg ( some of the clinical research was done at this dose) to enhance memory, focus, and improve dopamine function. Since most everyone slamming energy drinks probably needs a little dopaminergic love this should feel much different then just a jolt of caffeine.

They also are choosing to supply caffeine sourced entirely from Green Tea extract under the trademarked InnovaTea which is 98% caffeine from green tea. Usually Green tea is around 50% extract in form and host some EGCG and L-Theanine along with it, but they choose to just get straight to the point.

They also include some basic B vitamins for energy and brain support and a little bit of N-Acetyl-L-Tyrosine for adrenal and stress support. This rounds out the formula nicely and at a $2.50 price point puts the Superbrain RTD right in play among other competitors. As we know when it comes to taste and flavors Cellucor does not mess around so expect this to be a solid 9 or 10 in the flavor department out of 10.
