SPORT Carb adds Himalayan Pink Salt and Organic Coconut Sugar as transporters that drive KarboLyn® into muscles more efficiently, supercharging its athletic performance-enhancing benefits.

Flavored and sweetened with organic cocoa, vanilla bean, cinnamon, coconut palm sugar, yacon root, monk fruit and stevia, SPORT Carb is the cleanest, best-tasting sports carbohydrate drink.

Supplement Facts

SPORT Carb: The future of athletic carbohydrate supplementation.

The harder you exercise, the faster you burn through glycogen muscle fuel. Low muscle glycogen stores may limit your athletic advancement due to:

  • Performance crashes: Reduced muscle power and diminished endurance during training and competition; hitting the wall earlier
  • Muscle limitations: Without glycogen, muscle tissue is catabolized to produce energy; less energy also means slower muscle growth and recovery

Carbohydrates have long been used by athletes to prime muscle glycogen stores for peak performance and growth. But traditional carb sources have always had drawbacks:

  • Simple Carbs: Spike muscle energy quickly for intense shorter-duration bouts of exercise but may be followed by a net muscle energy crash
  • Complex Carbs: Load muscle energy for endurance and growth, but take a long time to absorb (up to 24 hours) and may cause bloating

NOW: SPORT Carb conquers carbohydrate muscle-loading challenges with KarboLyn® nutritional technology + Performance Lab® ultramodern design.

SPORT Carb KarboLyn® is bioengineered for enhanced carbohydrate fueling: Designed to a small molecular mass that absorbs quickly, but sustains muscle energy for 2+ hours.


SPORT Carb delivers all simple and complex carb benefits with none of the drawbacks:

  • Loads muscle with glycogen faster for quick strength
  • Sustains peak muscle power longer for extended endurance
  • Refuels muscle over hours to steadily power growth after exertion
  • No carb crashes, absorption delays, bloating or gastric distress

Universal Carbohydrate Sports Nutrition

Due to its fast-absorbing + sustained-release design, SPORT Carb is universal carbohydrate sports nutrition that can be taken by anyone at any time for all athletic goals.

Goal How to Take Athletic Performance Advantages
Strength 2-3 hours before training or competition 2+ hours of stim-free muscle energy; enhances training, competitive performance and ultimate muscle growth
Endurance Sip during training or extended exertion Tops off muscle glycogen for steady muscle energy in endurance athletics and extended bouts of physical exertion
Recovery Within 30 minutes post-workout Restores training-depleted muscle glycogen quickly for recovery, muscle growth and faster return to form
Growth Rest day Continues muscle-fueling during downtime to power the energy-intensive task of muscle repair and growth

Natural Organic Chocolate Taste

Who should take Performance Lab® SPORT Carb?

SPORT Carb can be taken by all types of athletes across all games, training regimens and competitions. It absorbs quickly, providing a fast source of energy that is ideal for powerlifting, other explosive movements, sprinting, etc. Because it has a sustained release that lasts two hours, it is also ideal for endurance activities like triathlons, long distance running, cycling, and competitions or tournaments that last all day. Finally, SPORT Carb can be taken after any exertion as the recovery supplement that reloads depleted glycogen muscle stores quickly and efficiently – thereby accelerating muscle recovery and return to peak form.

How do I take Performance Lab® SPORT Carb?

Mix 2 scoops (50 g) with 12 oz. (360 ml.) of water. Take 30 minutes before, during, and immediately after training and competition to support fast muscle energy, extended endurance, and robust growth and recovery. SPORT Carb is flavor-matched with SPORT Protein; they can be mixed together into a delicious 2-in-1 ergogenic drink.

Is Performance Lab® SPORT Carb safe?

Like other Performance Lab® supplements, SPORT Carb is designed to be safe for long-term daily use, without the need for cycling. SPORT Carb achieves this by using pure, potent ingredients that are dosed appropriately and in line with clinical research. SPORT Carb’s clean formula design – free of GMOs, gluten, soy, colorants, preservatives and other additives – is also well-tolerated by the body, and safe for long-term use. SPORT Carb avoids the use of caffeine and stimulants, further strengthening its safety and tolerability profile.

Why is there no caffeine in Performance Lab® SPORT Carb?

Some Carbohydrate supplements supply caffeine and other stimulants that may be poorly dosed or harsh. SPORT Carb is stimulant-free by design. Instead of caffeine, SPORT Carb enhances muscle energy with the cleanest, most effective carb on the market: KarboLyn®. For those who prefer caffeine, we recommend stacking SPORT Carb with Performance Lab® Stim.
