What do I need to buy?
Everything you need to mix this at home. We primarily recommend Nutricost-brand products (made in GMP-compliant, FDA-registered facilities, third-party tested) and fall back to NOW Foods or BulkSupplements for the few ingredients Nutricost doesn't stock. Each row shows the same product across Nutricost, iHerb, and Amazon — sorted by unit price, with the cheapest highlighted.

Tailwind High Carb is a different product from regular Tailwind Endurance Fuel (the 100g scoop here is roughly 4x the carbs of a standard Tailwind scoop). When comparing notes against Tailwind Endurance Fuel reviews online, those are about the moderate-carb formula — the High Carb is the recent SKU aimed at the elite end of carb intake.
DIY wins
- 90g of 2:1 dextrose + maltodextrin + fructose for ~50¢ vs $2.75 retail — the cleanest DIY copy in the high-carb premium tier.
- Robust 660mg sodium dose is genuinely useful for hot-weather coupled fueling — and easy to replicate at home with sodium citrate.
- No proprietary chemistry to miss. No hydrogel, no Cluster Dextrin, no trade-secret blend.
Where Tailwind Nutrition still earns its price
- Pre-measured sachet logistics are real value for race-day pacing and feed-zone handoffs.
- Brand-consistent flavor across batches is harder to nail at home, especially for fruit-forward profiles.
- If you're already on Tailwind for the broader product line (Endurance Fuel, recovery products), brand loyalty has its own value.
Is Tailwind Nutrition High Carb Endurance Fuel actually worth it?
Tailwind High Carb Endurance Fuel is Tailwind's answer to the high-carb premium tier — Skratch Super High-Carb, Maurten 320, SiS Beta Fuel — using a fundamentally different design choice. Where Maurten and SiS bet on the 2:1 dual-transporter optimum and Skratch bets on Cluster Dextrin's ultra-low osmolality, Tailwind picks 2:1 as the carb ratio (well-tested at moderate-to-high intakes) and uses dextrose, maltodextrin, and fructose — all commodity ingredients you can buy in 5-pound bags on Amazon.
What the formula actually is: 90g of carbs split across dextrose, maltodextrin, and fructose, with about 660mg of sodium plus modest potassium and magnesium per 100g scoop. The 2:1 ratio (60g glucose-equivalent : 30g fructose) is the older O'Brien & Rowlands optimum that's well-supported up to roughly 90g/hr — exactly the dose this product targets. It's a deliberately conservative formulation: no novel chemistry, just well-tested sugars at well-tested ratios.
Where Tailwind High Carb earns its product position is the electrolyte design. 660mg of sodium per serving is more than double what Maurten 320 ships with and ~150x what SiS Beta Fuel ships with after the 2021 reformulation. For long, hot rides where sweat sodium losses dominate, that coupled fuel-and-electrolyte design is genuinely useful — you don't need a separate electrolyte product running alongside the bottle.
Economics: $2.75 per 100g scoop is moderate for the high-carb premium tier (Maurten 320 is $3.75, Skratch Super High-Carb is ~$5.24, SiS Beta Fuel is $2.70). DIY at matched macros — bulk dextrose + maltodextrin + fructose + sodium citrate + a touch of magnesium — runs about 50 cents per scoop. The difference is the brand, the packaging, the flavor consistency, and the convenience of pre-measured single-serving sachets. The chemistry is identical.
The case for DIY is strongest on this product. Tailwind High Carb is, by design, a non-novel formulation — the brand isn't claiming proprietary chemistry, just a well-tested combination of commodity sugars at the right ratio. There's no hydrogel to miss, no Cluster Dextrin to substitute, no proprietary blend behind a trade secret. Match the ratio, match the sodium dose, and the drink in your kitchen is the drink in the sachet.
What's in this recipe?
Each ingredient links to a deeper guide — what it is, how it works in your gut, and where to buy it in bulk.
- Maltodextrin
The glucose-polymer workhorse in almost every high-carb sports drink — same energy as dextrose, far lower osmolality, nearly tasteless.
- Fructose
The GLUT5-transported sugar that lets you push past the 60 g/hr glucose ceiling — pair with maltodextrin at ~1:0.8 for the modern dual-transporter formula.
- Sodium Citrate
A smoother-tasting sodium source than table salt — the alkalising buffer commercial drinks use to dose sodium without the bite.
- Potassium Chloride
The cheapest, densest source of potassium for sports drinks — same form LMNT, Tailwind, and Precision Fuel use.
- Magnesium Malate
The magnesium form LMNT chose for Recharge — highest elemental-Mg fraction of any common powder, clean taste, well-tolerated.

Frequently asked questions
Why does Tailwind use 2:1 instead of 1:0.8 like Maurten and SiS?+
2:1 is the older O'Brien & Rowlands research optimum — well-tested up to ~90g/hr, which is exactly what Tailwind High Carb doses. The 1:0.8 ratio's measurable advantage shows up most clearly at intake rates above ~80g/hr where dual-transporter utilization is the rate-limiter. At Tailwind's targeted dose, 2:1 is well within the absorption envelope. It's a defensible engineering call, not a worse one.
Is the 660mg of sodium in one scoop too much?+
It's a high single-serving dose, but matched to the use case. For long, hot rides where you're losing 800-1500mg of sodium per hour in sweat, two scoops of Tailwind High Carb per bottle plus another bottle of plain water gets you toward those sodium targets without juggling salt tabs separately. For cool conditions or low sweat-rate athletes, two scoops will taste salty — you'd want to dilute or pair with a less-salty drink.
What's the simplest DIY shopping list?+
Bulk dextrose (~$15 per 5lb), bulk maltodextrin (~$25 per 8lb), crystalline fructose (~$15 per 2lb), sodium citrate (~$15 per 1lb), and optional citric acid for tartness and flavor extracts. Per scoop: roughly 30g maltodextrin + 30g dextrose + 30g fructose + ~1.5g sodium citrate (delivering ~400mg sodium) + a pinch of salt for the rest. Total: ~50 cents per matched scoop.
How does Tailwind High Carb compare to Skratch Super High-Carb?+
Both target ~100g/hr fueling but with different chemistries. Skratch leans on Cluster Dextrin (HBCD) at a 12:1 glucose-to-fructose ratio for ultra-low osmolality at high concentrations. Tailwind High Carb uses dextrose + maltodextrin + fructose at a 2:1 ratio for the well-tested dual-transporter range. Per gram of carb at retail, Tailwind is meaningfully cheaper. Per gram at home, both are cheap, but the Skratch DIY needs HBCD (~$50-80/kg) where the Tailwind DIY needs only commodity sugars.
Can I just use Gatorade powder for this?+
Sucrose-and-dextrose-based commercial sports drinks (Gatorade, Powerade) hit a roughly 2:1 ratio naturally because sucrose is 1:1 glucose-fructose and dextrose adds glucose. The catch is concentration — they're formulated at ~6% concentration for hydration, not the higher-concentration carb dose Tailwind High Carb targets. To turn Gatorade powder into a 90g/scoop drink you'd need to roughly triple the per-bottle dose, which the brand isn't engineered for. Bulk DIY with proper ratios is more accurate.
Will it taste like Tailwind?+
Closer than you'd expect. Tailwind's flavor profile (lemon, raspberry, etc.) comes from real-fruit powders and citric acid that are cheap to add at home. Without flavoring, the DIY scoop tastes mildly sweet and a little salty — adding a pinch of citric acid and a few drops of natural fruit extract gets you in the same family. Tailwind's specific flavor IP is the part you can't perfectly replicate, but the underlying drink is the same drink.
