Best Carb & Electrolyte Powders in Canada (2026) | Endurance Fueling Guide

Joe Clark | BSc Hons Sport Science

If you’re an endurance athlete looking for the best carb & electrolyte powder to fuel your performance, this is the guide for you. Here, we take the 8 brand leaders and compare them against real sweat loss science to determine which is best for performance. 

Comparing fueling products can be difficult due to inconsistent scoop sizes, serving sizes, and marketing claims. To address this, all products have been normalised to 30, 60 and 90 g of carbohydrate to compare each product at each fueling rate against the sweat loss data. 

The products analysed are:

  • Skratch: Hydration Sport Drink Mix
  • Skratch: Super High Carb
  • Tailwind: Endurance Fuel
  • Tailwind: High Carb Fuel
  • Maurten: Drink Mix 160
  • Maurten: Drink Mix 320
  • Precision Hydration: Carb & Electrolyte Drink Mix
  • Thrive: EnduraFuel

The effect of fueling on performance

The top brands compared here all recognize the importance of carbs and electrolytes, which is why they include both in their formulas. 

Research shows that consuming carbohydrates with electrolytes helps prevent fatigue and supports sustained endurance performance. In running, fueling during racing has been shown to reduce overall time by 3.9 minutes (~2%) (1), while another study found electrolytes decreased time by 7.9% (2). A meta-analysis of 50 studies in running and cycling found that carbohydrate intake of 30–80 g/h improves time trial performance by ~2.0%, with larger improvements observed in time to exhaustion (15.1 %, and even greater 54.2% improvement when already pre-fatigued) (3). 

Sweat Loss Science

Electrolytes lost in sweat

Data from a large study of 506 athletes, including cyclists, runners, and participants from various sports, showed that sweat losses typically range from 1.0 to 1.9 litres per hour of physical activity, depending on exercise intensity and climate with an average of 1.2 L per hour.

Research shows that the associated electrolyte losses for 1.2 L of sweat (average hourly losses) are as follows:

  • Sodium: 991 mg (3)
  • Potassium: 439 mg (4)
  • Calcium: 53 mg (5)
  • Magnesium: 12 mg (5)

I’ve included this data as a reference for analysing the electrolyte dosing of the products, and colour coded the tables relative to how the products perform against these values. 

For a deep dive into the data of sweat losses during exercise, read this article.

Sodium Content

Average sodium loss is ~991 mg per hour (3), however, 100% replacement while fueling isn’t necessary. Guidelines from ACSM, NATA, and DGE suggest ~700 mg of sodium per litre of fluid as optimal, alongside fluid intakes of 600 mL–1.2 L per hour. This equates to an optimal sodium intake during exercise of roughly 400–840 mg per hour.

Potassium Content

Average potassium loss in sweat is ~439 mg per hour (4). Again, complete replacement during training isn’t necessary; however, potassium losses are still meaningful, so the product should include some potassium to support replenishment. While there is less clinical data defining an exact optimal target, typical losses of ~439 mg per hour suggest that an inclusion of 100–200 mg is likely sufficient.

Calcium Content

Average calcium loss during exercise is ~53 mg per hour (5). Replenishment during exercise is not necessary to maintain performance, though small amounts are often included to help offset losses.

Magnesium Content

Average magnesium loss during exercise is ~12 mg per hour (5). Magnesium replacement during exercise isn’t essential for performance, but small amounts are often included to help offset losses and support overall intake, which is important for health.

 

Electrolyte Summary

If fueling at 30 g of carbohydrate, the best choices are:

  • Skratch Hydration Sport Mix
  • Precision Hydration Carb & Electrolyte Drink Mix
  • Thrive EnduraFuel
  • Tailwind Endurance Fuel

Each provides sufficient electrolytes at a 30 g per hour of carb fueling rate.

At 60 g and 90 g per hour, Tailwind High Carb Fuel also meets the minimum electrolyte requirements. 

Precision Hydration and Thrive EnduraFuel most closely reflect actual electrolyte sweat losses from exercise. Skratch Hydration Sport Mix delivers the highest total electrolyte content, particularly sodium, which may suit some athletes; however, it is overdosed in calcium and magnesium and slightly low in potassium.  Tailwind Endurance Fuel also provides a solid profile but is slightly lower in sodium and potassium. Overall, all four perform well from an electrolyte standpoint.

In contrast, Maurten Drink Mix 160, Drink Mix 320, and Skratch Super High Carb do not provide a complete electrolyte profile and fall short on sodium at most fueling levels, except at 90 g per hour. Given their cost, they offer limited value. The Maurten mixes are primarily maltodextrin and fructose with added sodium, while Skratch Super High Carb includes cluster dextrin, which may improve GI tolerance at very high intakes, but is unnecessary for most and comes at a higher cost.

Carb Type & Glucose: Fructose

A ~2:1 glucose to fructose ratio is generally considered optimal, as it maximises total carbohydrate absorption by utilising multiple intestinal transporters (SGLT1 for glucose and GLUT5 for fructose), increasing delivery to the working muscle (6). 

Cost

The table below shows the product costs; most usefully, it shows the net cost per 100 g of powder. I’ve ranked them in order of cost.

Overall Winners

Here is the overall results taking into account each category above. 

While the top four are all strong fueling choices, the overall winner is Thrive EnduraFuel as it most closely matches the sweat loss research, as well as providing the optimal carb type and good value for money - it is also the only product which is made in Canada. 

Each of the top four contains a complete electrolyte profile with dosages that align with scientific research on sweat loss values. Tailwind Endurance Fuel didn’t quite make the top three because it has less than a 2:1 glucose-to-fructose ratio, but other than that, it's a strong product.

The bottom three are simply carbs and sodium, so they don’t provide a complete fueling solution as they require a separate electrolyte supplement, yet they cost just as much, if not more in some cases.

Appendix: Nutrition Facts Panels

These are the original nutrition facts panels for each product, I’ve included them here for reference. In the analysis above, the values were normalised to 30, 60, and 90 grams of carbohydrate, since comparing these panels directly isn’t possible without first making them equivalent.
