Why VFuel

Designed for the long haul.

Fast, Sustained Energy

Maltodextrin and glucose deliver rapid carbohydrate energy through dual absorption pathways, designed to support steady output throughout extended efforts — not just the first 30 minutes.†

No Added Fructose*

No high-fructose corn syrup, no added fruit sugar. Cool Citrus is formulated to be well-tolerated across long training days and race conditions. *Excluding trace amounts from lemon juice and natural flavors.

Amino Acid Complex†

Every pack contains L-Citrulline, L-Ornithine, and Taurine — amino acids studied for their roles in endurance performance, circulation support, and post-exercise recovery processes.

MCT Oil Included

Medium-chain triglycerides are included alongside carbohydrate sources, providing a fat-based energy substrate that metabolizes differently from long-chain dietary fats.

Electrolyte Support

Sodium Citrate, Magnesium Chloride, and Potassium Chloride are included to help replace key minerals lost through sweat during prolonged activity.

Made in Japan

Every batch is manufactured in Japan under strict quality standards, with a 24-month shelf life. Clean production from source to pack.

Same fuel. Same result.

Usage Guide

When to reach for Cool Citrus.

Long Runs (60+ min)

The clean citrus flavor is designed to stay palatable over repeated servings — ideal when flavor fatigue is a concern.

Cycling & Gravel

Easy to consume on the move. Works well alongside VFuel Drink Mix for a complete in-ride fueling strategy.

Trail & Ultra Running

Lemon-forward flavor is refreshing in warm conditions. Low gut load supports digestion during very long efforts.

Triathlon

Take pre-swim or on the bike leg. Pairs cleanly with water during the run portion.

Endurance Gels Cool Citrus

Suggested Timing

15–30 min before
Take one pack pre-activity to prime carbohydrate availability.
Every 45–60 min
Repeat throughout activity. Adjust to effort level and individual tolerance.
Always with water
Follow each gel with 4–8 oz of water to support absorption.

Target 30–60g of carbohydrates per hour during sustained efforts. Pair with VFuel Drink Mix to reach higher intake targets on long race days.

Transparency

Everything in the pack, and why.

VFuel uses a short, purposeful ingredient list. Every component is selected for a specific performance or palatability role — nothing added for appearance or margin padding.

Endurance Gels Cool Citrus

Full Ingredient Statement (FDA Order)

Maltodextrin, Water, Glucose, MCT Oil (Medium-Chain Triglycerides), Concentrated Lemon Juice, Natural & Artificial Flavor, Emulsifier (Sucrose Fatty Acid Ester), Sodium Citrate, L-Taurine, L-Ornithine Hydrochloride, Magnesium Chloride, L-Citrulline, Potassium Chloride, Salt (Sodium Chloride), Caffeine.

Maltodextrin
Primary Fuel
The primary carbohydrate source. A complex carbohydrate digested via the same gut transporter as glucose, supporting high carbohydrate uptake rates without intestinal overload.
Glucose
Fast Energy
Simple sugar absorbed directly and rapidly. Combined with maltodextrin to provide immediate plus sustained carbohydrate energy across an effort.
MCT Oil
Fat Substrate
Medium-chain triglycerides metabolize more rapidly than long-chain dietary fats, providing an additional energy substrate alongside the carbohydrate base.
Sodium Citrate
Electrolyte
Helps replace sodium lost through sweat. Also acts as a buffering agent and is milder in taste than sodium chloride alone.
L-Citrulline
Amino Acid
Precursor to arginine, which plays a role in nitric oxide production and circulatory function. Studied in endurance contexts for potential to support blood flow during exercise.†
L-Ornithine
Amino Acid
Involved in the urea cycle, which plays a role in clearing ammonia — a metabolic byproduct that accumulates during prolonged exertion.†
Taurine
Amino Acid
A conditionally essential amino acid associated with cellular hydration, electrolyte balance, and antioxidant functions during exercise stress.†
Magnesium Chloride
Electrolyte
Magnesium supports over 300 enzymatic reactions, including those involved in energy metabolism and muscle contraction. Losses through sweat are significant during long efforts.
Concentrated Lemon Juice
Natural Flavor
Provides the bright citrus flavor profile. Contains trace fructose inherent to the fruit — the only fructose source in this formula. *See fructose disclaimer.
Caffeine
Stimulant · 11 mg
At 11 mg per pack, a conservative dose roughly equivalent to a small sip of coffee. Designed to complement, not dominate, your fueling strategy.

What's not in the pack.

No Added Fructose*

No high-fructose corn syrup, no added fruit sugar. The only fructose present is from concentrated lemon juice — a trace amount inherent to the fruit itself. *Excluding trace amounts from lemon juice and natural flavors.

No Artificial Sweeteners

Sweetness comes from glucose and maltodextrin — not aspartame, sucralose, or stevia.

No Artificial Colors

Color comes from the ingredients themselves. No FD&C dyes or synthetic colorants.

No Gluten

Formulated without gluten-containing ingredients. Produced in a facility that processes other food items — consult your physician if you have celiac disease.

*Fructose-free: Cool Citrus contains no added fructose. Concentrated lemon juice contributes a trace amount of naturally occurring fructose inherent to the fruit. Athletes with severe fructose intolerance should consult a dietitian or physician before use. † These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.

FAQ

Common questions.

Most mainstream gels use a maltodextrin + fructose blend. VFuel Cool Citrus is formulated without added fructose, using maltodextrin and glucose instead. It also includes MCT Oil as a fat-based energy substrate, and a full amino acid complex (Citrulline, Ornithine, Taurine) that many gels omit. The result is a more complete endurance formula in a single packet.

We strongly recommend consuming each gel with 4–8 oz (120–240 ml) of water. Water helps dilute the concentrated carbohydrates, supports absorption across the intestinal wall, and keeps the formula from sitting heavily in your stomach. Taking gels without water during exercise is a common cause of gastrointestinal distress.

Cool Citrus contains approximately 11 mg of caffeine per pack — a conservative amount, roughly comparable to a small sip of coffee. This is intentionally low to allow you to stack multiple gels without accumulating a high caffeine load. If you need more caffeine support, Cafe Mocha contains approximately 32 mg per pack.

VFuel does not add fructose to its formula. However, concentrated lemon juice — used for flavoring in Cool Citrus — contains trace amounts of fructose inherent to citrus fruit. Athletes with severe fructose malabsorption or hereditary fructose intolerance should consult a dietitian or physician before use.

Yes — VFuel gels and drink mixes are designed to complement each other. The drink mix provides approximately 190 kcal per pack with high-concentration electrolytes; combining with a gel every 45–60 minutes can help you meet the 60–90 g/hr carbohydrate targets recommended for events lasting over 2 hours. Both products use non-fructose carbohydrate sources, so they stack cleanly.
