Product Benefits: Cellucor® C4® Smart Energy – 20 Sachets is a next-generation cognitive-enhancing energy drink designed to fuel both the body and the brain. Combining the physical performance benefits of the C4® series with clinically studied nootropic ingredients, this product delivers smooth, sustained energy, enhanced focus, and improved mental clarity — without sugar, crashes, or overstimulation. At its foundation is beta-alanine (CarnoSyn®), an amino acid that boosts muscular endurance by increasing intramuscular carnosine concentrations. While traditionally known for athletic benefits, beta-alanine also supports cellular function and antioxidant defense, making it suitable for daily energy and resilience. The core stimulant in the formula is caffeine anhydrous (200 mg) — a purified, fast-acting form of caffeine that enhances alertness, attention, motivation, and energy output. Unlike traditional energy drinks, C4® Smart Energy complements caffeine with L-theanine, a calming amino acid known to smooth out stimulant effects, improving focus without anxiety or jitteriness. A key differentiator is Cognizin® (Citicoline) — a highly bioavailable nootropic that supports memory, mental processing speed, and concentration. Citicoline increases levels of phosphatidylcholine in the brain, a critical nutrient for cell membranes and neurotransmitter function. This makes the product ideal not only for workouts, but also for mentally demanding tasks like studying, presentations, or long workdays. L-tyrosine further enhances cognitive resilience, especially under stress. It supports dopamine and norepinephrine production, neurotransmitters vital for motivation, reaction, and mental stamina. Whether facing a challenging workout or an intense day at the office, L-tyrosine helps users stay sharp and focused. To support metabolic function and reduce fatigue, the formula is enriched with B vitamins — including niacin (B3), pyridoxine (B6), and cyanocobalamin (B12). These micronutrients contribute to energy-yielding metabolism, nervous system health, and psychological performance. The product is free from sugar, aspartame, and artificial dyes. It is sweetened with sucralose and acesulfame potassium, making it suitable for calorie-controlled diets. The powder dissolves easily in water, creating a clear, refreshing beverage with clean taste and quick effect. C4® Smart Energy Sachets are ideal for:
Students during exam preparation
Office professionals needing clean energy without crashing
Creatives and entrepreneurs seeking sharp mental focus
Athletes or gym-goers preferring a non-creatine, cognitive-enhanced pre-workout
Travelers or shift workers dealing with mental fatigue and irregular hours
