Dual-carb fuel for endurance with real electrolytes and no stimulants.
Raw Nutrition Fuel is a no-nonsense endurance drink focused on the big two for long hauls: carbs to keep you going and electrolytes for hydration. It's not some stim-packed pre-workout dressed up as endurance gear. This is straight-up intra-workout fuel to help you hold your pace when sessions drag on, sweat pours out, and your energy tanks start running low.
The heart of it is the carb setup. Each scoop gives you about 24-25g of carbs in a 1:0.8 glucose-to-fructose ratio from maltodextrin, cane sugar, and fructose. Here's why that ratio rocks: glucose uses one gut transporter (SGLT1), fructose another (GLUT5). Mixing them lets your body absorb and burn more carbs than a straight glucose drink. Sip this repeatedly during long workouts, and you can bump up your hourly carb intake, keeping muscle fuel and blood sugar steady to fight that end-of-session drag.
Electrolytes are straightforward, not overdone. You get around 300mg sodium per serving, with 230-240mg chloride. Chloride doesn't get much hype, but it's crucial—it's a key electrolyte outside cells, teaming with sodium and potassium for fluid balance, acid-base stuff, and keeping nerves and muscles firing right. For sweaty athletes, sodium and chloride are the hydration MVPs. There's also a bit of magnesium, calcium, and potassium, but doses are low—magnesium's just 4-5mg, way under the 310-420mg daily supplement range, calcium

Key Highlights
- 24-25g quick carbs per serving—that's the power here. It matters because when carbs run low, your performance tanks fast, and this gives you a handy amount to sip through the hour instead of one big dump.
- 1:0.8 glucose-to-fructose ratio—a smart setup backed by studies. These sugars use different gut paths, so you get better carb flow and steady energy for those longer pushes.
- Made for sipping during workouts, not just a one-shot deal. The serving's easy to handle repeatedly, packing enough carbs to hit your hourly goals.
- 300mg sodium per serving—a solid base for sweaty sessions. Sodium helps keep fluids in check and makes you want to drink more during long efforts.
- 230-240mg chloride per serving—sodium's key teammate that's often overlooked. It keeps fluids balanced and muscles/nerves humming, making this a legit endurance drink.
- No stims at all—no caffeine, no heart pounding, no drop-off. Perfect for races, late workouts, doubles, or stacking with your regular pre without extra buzz.
- No hidden blends—the main drivers are right there. Unlike vague labels, you see the carb and electrolyte plan clear as day.
- Informed Sport certified—big plus for serious or tested athletes. It means it's checked for banned stuff, which beats fancy claims any day.

Who Is This For?
- Runners going over 60-75 minutes who need tolerable fuel on the move. The 1:0.8 glucose-to-fructose carbs boost hourly intake, with sodium and chloride handling sweat.
- Cyclists and tri folks on long rides or combos where energy drops before legs do. 24-25g carbs scale easy, stim-free keeps pacing real for race practice.
- HYROX and CrossFit grinders in long conditioning who want liquid energy over gut bombs. Quick carbs fuel repeats, electrolytes help in sweaty spots.
- Field-sport players in camps or doubles burning glycogen fast without stim overload. Boosts capacity without caffeine hitting sleep or recovery.
- Combat athletes in volume sessions needing steady output without jitters. Carbs and electrolytes fit pads, drills, rounds better than stim pre's.
- Folks with a separate pre who skip double stims in hydration. Value's from carbs and electrolytes, not buzz.
How to Use
Mix one serving in water and sip during your workout, not gulp it down. For 45-60 minute sessions, one's often plenty; for tougher endurance, bump servings per hour based on your size, sweat, and carb needs. Shaker's best for even mixing—beats stirring. Add more water for lighter flavor and easier gut feel, especially in heat. Start early to stay ahead on energy. Great fasted too, filling in what you skipped. Stacks with creatine, extra electrolytes, or caffeinated pre. No cycling needed—it's fuel, not stim stuff. Keep it sealed, cool, and dry for best taste.
What to Expect
First 0-10 minutes, it's easy drinking—not heavy like food. No buzz, no shakes, no fake pump since this is about fuel flow, not revving your nerves. 10-30 minutes in, you feel more even keel if you sip early, not some huge surge. From 30-90 minutes and on, that's Fuel's sweet spot: energy holds steady, pace sticks, hydration feels solid vs. plain water. Days 1-7, you figure your sip rate and hourly scoops more than any build-up. Weeks 2-4, the real perk is nailing long sessions with reliable fueling instead of winging it.

Frequently Asked Questions
What makes Raw Nutrition Fuel an endurance formula instead of a pre-workout?
Its core performance drivers are 24-25g of carbohydrates in a 1:0.8 glucose-to-fructose ratio plus a practical electrolyte profile anchored by about 300mg sodium and 230-240mg chloride. There are no stimulants, so the formula is built to maintain energy and hydration during longer sessions rather than create a short-lived CNS boost.
How many carbs are in each serving of Raw Nutrition Fuel?
Each serving provides roughly 24-25g of carbohydrates, depending on source panel formatting. That amount is useful because it lets athletes build a structured hourly fueling plan by scaling servings based on workout duration and intensity.
Why does the 1:0.8 glucose-to-fructose ratio matter?
Glucose and fructose use different intestinal transporters, primarily SGLT1 and GLUT5. Combining them allows more total carbohydrate absorption and oxidation than relying on a single carbohydrate source alone, which is why this approach is favored in modern endurance fueling.
Does Raw Nutrition Fuel contain caffeine?
No. This is a stimulant-free formula, which makes it easier to use during races, long aerobic sessions, evening training, or alongside a separate caffeinated pre-workout.
Is one serving enough for a long workout?
For shorter sessions or lighter fueling needs, one serving may be enough. For longer endurance work, most athletes will need multiple servings per hour or additional fuel sources, because one 24-25g serving is a building block rather than a full-hour solution for high-demand efforts.
Are the electrolytes fully dosed like a dedicated hydration product?
The sodium and chloride amounts are the meaningful part of the electrolyte profile here. The magnesium, calcium, and potassium are present in very small amounts and are not clinically dosed as standalone mineral supplements.
Can I stack Raw Nutrition Fuel with a pre-workout?
Yes, and that is one of its biggest advantages. Because Fuel is stim-free, it pairs cleanly with caffeinated pre-workouts, creatine, or amino acids without duplicating stimulant load.
When should I drink Raw Nutrition Fuel?
It works best when sipped during training and started early in the session rather than saved for when fatigue already hits. Endurance fueling is most effective when you stay ahead of depletion instead of trying to reverse it once performance is already dropping.
Is this a good race-day option?
It can be, especially for athletes who have already tested it in training. The glucose-fructose setup and stim-free profile are race-appropriate, but all carbohydrate products should be practiced before competition to confirm GI tolerance.
What about the listed vitamins and iron?
Vitamin C, vitamin D, and iron appear on the panel, but the provided data does not disclose their amounts. Because of that, they should be treated as secondary details rather than primary reasons to choose the product.
