It starts with
the formula
Today, more than ever, any advantage should be your advantage. The science behind our C4 Energy and C4 Smart Energy gives you the daily edge to crush every obstacle and be ready for whatever comes next.
Brain

C4 Smart Energy
C4 Smart Energy sharpens your attention, boosting memory and performance.
Clean Energy
Innovatea®
INNOVATEA® Delivers the clean energy of naturally derived caffeine.
C4 Smart Energy also includes Innovatea®, naturally derived caffeine from Green Tea, free from pesticides, and Non-GMO project verified.
Focus + Attention
Cognizin®
Take Citicoline. It’s a naturally occurring nutrient in our brains, and it helps our neurotransmitters send signals across billions of synapses. When we are depleted of Citicoline, neurotransmission may suffers.
Cognizin® is a proprietary form of Citicoline, and the subject of numerous clinical studies, setting it apart from many other Citicoline ingredients
A clinically-studied ingredient, Cognizin boosts helps increase levels of phosphatidylcholine, an important phospholipid that helps protect brain membranes, and strengthen cell structure, maximizing enhance neurotransmitter output, and it supports healthy mitochondria, the cellular engines powering the brain.1
THE C4 SMART ENERGY BENEFIT IS GREATER MENTAL ENERGY, FOCUS AND ATTENTION.

N-Acetyl-L-Tyrosine
Natural Flavors
Free of artificial colors and flavors, C4 Smart Energy comes in a wide range of dynamic flavors including Cotton Candy, Electric Sour, Freedom Ice, and Peach Mango Nectar.
Body

C4 Energy
C4 Energy promotes endurance, hydration and heightened physical performance.
Explosive Energy
Caffeine Anhydrous
200mg of Caffeine Anhydrous delivers key pre-workout benefits.
From boosting the metabolism and promoting fat burning, it increases endurance, improves circulation, pain reduction and preserves muscles.
Natural Hydration
Betapower® Betaine
Naturally-derived from beets, BetaPower Betaine helps to support hydration and better physical performance.
- An increase of 30% in squat repetitions after a 7-day betaine intake.3
- An increase of 60% after a 14-day betaine intake.3
- A significant increase in the quality of repetitions performed (at reps performed at 90% of the subjects’ maximal performance) after 7-day and 14-day betaine intake.3
BetaPower Betaine delivers C4 Energy the power of beets—call it our super food.
Muscular Endurance
CarnoSyn®
Take CarnoSyn®. A clinically-studied form of Beta-Alanine, an amino acid found within our skeletal muscle tissue. CarnoSyn® is backed up by 55 studies that support its effectiveness in INCREASING MUSCULAR ENDURANCE, SUSTAINING PEAK POWER OUTPUT DURING ANAEROBIC TRAINING, AND REDUCING PERCEPTION OF FATIGUE*
- Cyclists saw a boost of 11.4% above baseline, in improved muscle endurance but while fatigued at the end of a time trial, compared to placebo, after 8 weeks of usage.2
- High-intensity interval training athletes increased their muscular endurance and better lean body mass in 6 week trial.2
Only C4 Energy features CarnoSyn®.
