8 Best Electrolyte Powders in Canada According to Science (2026)

How many electrolytes do you actually lose while sweating?

Data from a large research study including 506 athletes showed that typical sweat losses during exercise range from 1.0 to 1.9 litres per hour, depending on exercise intensity and climate (low intensity = 1.0 L/hour, moderate intensity = 1.5 L/hour, high intensity = 1.9 L/hour). Individual sweat losses varied from 0.6 to 2.6 L/hour, as people sweat different amounts.

Replacing lost electrolytes during exercise helps maintain normal muscle and nerve function, while also preventing imbalances that can cause fatigue, headaches, cramps, and nausea (1). Proper electrolyte intake supports hydration and improves overall performance (2, 3) making it important for anyone involved in prolonged or intense activity.

To keep this analysis simple, we’ll use 1 litre of sweat per hour as the reference point and provide the associated losses in sodium, potassium, calcium, and magnesium based on scientific literature. We can then analyze how a scoop of each product compares to the requirements for 1 hour of lower-intensity exercise.

Typical electrolyte losses per litre of sweat:

• Sodium: 826 mg
• Potassium: 366 mg
• Calcium: 44 mg
• Magnesium: 10 mg
• Total electrolytes: 1,246 mg

The 1 litre of sweat per hour value used here is based on lower-intensity exercise. For moderate activity, sweat loss averages 1.5 litres per hour; and for very intense or hot conditions, 1.9 litres per hour (1).

The electrolyte losses stated above are averages from studies - some people will lose more, some less, but this gives us a solid baseline for analyzing electrolyte products.

It’s also worth noting that losses in sodium have been reported as high as 6,000 mg in a single hour, and potassium as high as 581 mg (5). This highlights how individual sweat response, exercise intensity, and climate conditions play a huge role. I mention this because you’ll soon see just how under-dosed many of these electrolyte supplements are.

Now, we’ll look at how a serving of each product compares to the scientific losses per litre of sweat for sodium, potassium, calcium, and magnesium. I’ve also included the actual mineral ingredient for each electrolyte and given a colour-coded grade based on absorption and bioavailability (green = optimal, orange = sub-optimal).

Sodium

For every 1 litre of sweat, the average sodium loss is 826 mg (4). This graph compares the sodium content of each brand to this 826 mg benchmark. 

LMNT, Thrive, and Wakewater all get the sodium content right. LMNT goes slightly higher at 1,000 mg, which makes sense since many people sweat more than 1 litre per hour. Thrive and Wakewater are both formulated to match the average sodium loss per litre of sweat.

Biosteel, Cira, NUUN, Organika, and Hydralyte all miss the mark when it comes to sodium content. Sodium is the most important electrolyte to replenish during exercise and should be the foundation of any electrolyte supplement. If you exercise and sweat, I recommend avoiding these brands entirely. In my opinion, their products are mis-marketed and offer little value to active individuals.

It’s also worth noting that if you do not exercise and sweat, you do not need an electrolyte supplement. Based on the marketing of Organika and Cira, it appears their products are not aimed at athletes. This likely explains the low sodium content; they are targeting consumers who don’t need substantial electrolyte replenishment, making these products little more than a money grab.

The choices of sodium from all brands are effective and bioavailable. Sodium chloride (“table salt”), sea salt, and sodium citrate are all effective for hydration and electrolyte balance. Sodium chloride is the most common and well-researched.

Potassium

For every 1 litre of sweat, the average potassium loss is 366 mg (5). This graph compares the potassium content of each brand to this 366 mg benchmark. 

All brands use good choices of potassium, and there are no studies that state that any particular form is better absorbed. Potassium citrate and bicarbonate have a mild alkalizing effect, which may be desired by some. 

Calcium

For every 1 litre of sweat, the average calcium loss is 44 mg (6). This graph compares the calcium content of each brand to this 44 mg benchmark. 

Dose: Thrive, Organika, and Wakewater all meet the sweat loss dose for calcium. All other brands are under-dosed, with LMNT and Hydralyte not including any calcium at all. LMNT provides a rationale for not including calcium, which is discussed in the overall winners summary.

Calcium citrate, calcium lactate, and calcium bisglycinate chelate are all better absorbed than calcium carbonate, especially on an empty stomach (7). Calcium bisglycinate chelate and calcium lactate are superior for absorption, while calcium carbonate is the most common and least expensive form but is less bioavailable if stomach acid is low. Tricalcium phosphate is less commonly used and not as well absorbed, making it a sub-optimal choice.

Magnesium

For every 1 litre of sweat, the average magnesium loss is 10 mg (6). This graph compares the magnesium content of each brand to this 10 mg benchmark. 

Note that magnesium is not lost in large amounts through sweat. However, it is very important for muscle function, so many brands include it primarily as a supplement for health and performance, rather than to replace actual sweat losses.

Dose: All brands meet the magnesium sweat loss dose except for Biosteel and Hydralyte. LMNT, Thrive, Organika and Wakewater all elect for a 50-60mg dose, which is largely to act as a low dose magnesium supplement as well as to buffer sweat losses.

Magnesium glycinate, magnesium citrate, and magnesium malate are highly bioavailable forms that are gentle on the stomach, making them superior choices for supplementation. Dimagnesium malate is also an excellent option. In contrast, magnesium oxide is poorly absorbed and can cause gastrointestinal upset in higher doses, making it the least effective form (8).

Total Electrolytes

Here is a comparison of how each product measures up against the total electrolyte loss reported in the literature discussed above. For every 1 litre of sweat, the average total electrolyte loss is 1,246 mg, based on the research values for sodium, potassium, calcium, and magnesium. This graph compares the total electrolyte content of each brand to the 1,246 mg benchmark.

Summary

In summary, only LMNT, Thrive and Wakewater come close to matching the electrolyte losses per litre of sweat. The other brands are massively under-dosed.

Non-Medicinal Ingredients

This is an overview of the quality of the non-medicinal ingredients used, not the electrolytes themselves.

Top marks here are achieved by using all natural ingredients, which are given to LMNT, Biosteel, Thrive, NUUN, and Organika. I’m not removing any marks for the number of ingredients, as, for example, the natural ingredients lecithin, rice hull, and dextrose are all clean, safe ingredients and are used for these products’ individual formulas.

Overall, Hydralyte is by far the worst here, using sucralose and mannitol for sweetener (both artificial), as well as maltose and pregelatinized starch. Second worst is Cira, with artificial flavours and sucralose. Wakewater drops the ball here a bit, as they have a fantastic product which is let down slightly by using artificial flavour.

I’ve penalized Cira, Wakewater, and Hydralyte for using artificial ingredients, as there’s really no need for artificial flavours or sweeteners in a product like this. Natural flavours and stevia work well with an electrolyte powder.

For anti-clumping, silicon dioxide is used by Cira, Wakewater, and Hydralyte. Although not widely considered unsafe, it isn’t an absolute necessity for an electrolyte powder. Thrive uses rice hull instead, which is completely natural and a clever solution to prevent clumping in their tub format. Brands using sachets don’t need any anti-clumping agents, as clumping tends to occur over time when stored in tubs - this is why LMNT and Organika don’t use any.

Product Comparison: Cost

Now, moving on to cost. Below, I have included the cost per serving. Bear in mind when analysing this comparison that only LMNT, Thrive, and Wakewater contain anywhere near an effective dose of electrolytes.

LMNT, Biosteel, Organika, Cira, Wakewater all use sachets (although convenient, they are more expensive due to the individual packaging).

NUUN and Hydralyte both use a effervescent tablet (although convenient, they are very under-dosed)

Thrive uses a tub of powder with a scoop, this is aimed at providing better cost effectiveness with a 75 serving container coming in at only $0.93/serving. Biosteel, Cira and Organika also do tub options. 

Overall Winners

To determine the overall ranking, I ranked each product by category (sodium, potassium, calcium, magnesium, total electrolyte content, ingredient selection), assigning 8 points for first place and 1 point for last place. I then summed the points and converted them into a percentage. No points were awarded for taste, but I discuss the taste of the top three winners in the next section. I also didn’t factor in cost here, as I wanted the rankings to reflect product quality alone. The different products use various delivery methods (sachets, effervescents, tubs), so I didn’t include this either, to avoid confusing the overall results.

Top three winners analysis

This analysis discusses the merits of the top three winners (Thrive, Wakewater, and LMNT). The other brands are so underdosed, that they aren't worth considering for true electrolyte replacement.

🥇Thrive Hydrate (first place, 47 points)

Thrive Hydrate takes the win for best electrolyte powder due to its scientifically optimised electrolyte ratios (800 mg sodium, 300 mg potassium, 50 mg calcium, 50 mg magnesium), the ideal total electrolyte dose, the use of only natural ingredients, and being by far one of the most cost-effective options at $0.93 per serving. The taste is also the best of all options, with well-balanced sweetness, saltiness, and acidity. This product took time and effort to design, being based on scientific literature, combined with clever formulation using only natural ingredients. By using a tub instead of sachets, it comes in at less than half the cost per serving of Wakewater and LMNT.

🥈WakeWater (second place, 41 points)

Wakewater is a great product. The electrolyte ratio is perfect and is the same as Thrive Hydrate (800 mg sodium, 300 mg potassium, 50 mg calcium, 50 mg magnesium). The only reason Wakewater scored lower than Thrive in the product analysis is that they use artificial flavours and silicon dioxide, whereas Thrive uses natural alternatives for both of these ingredients. Wakewater also comes in at $2.40 per serving vs Thrive’s $0.93 per serving, which is a significant difference. The taste of Wakewater is very good, with a good balance of sweetness and saltiness - my only comment is that it’s very acidic, which some people like, but it was a little strong for me and gave me slight heartburn.

🥉LMNT (third place, 38 points)

LMNT takes third place. The product is a solid option, although is not Canadian made like the Thrive and Wakewater. The main reason LMNT dropped to third is because the product contains no calcium. The science of sweat loss is clear: calcium is lost in significant amounts, with around 44 mg per litre of sweat (3). LMNT claim they don’t include calcium due to links between calcium supplementation and cardiovascular disease. However, this evidence is weak, inconsistent, and mostly based on non-athletic populations taking high-dose calcium supplements (600–1500 mg). In reality, someone sweating and receiving 50 mg of calcium per scoop of electrolyte powder is at no risk of increased heart disease.

LMNT is also extremely expensive ($2.75 per serving) for what is essentially a packet of salt. There’s no real reason for it to cost this much. It’s simply because they are a brand leader and people will pay the premium, much like AG1 and greens powders.

Finally, in regards to taste, LMNT tastes like drinking salt water. This is fine if you enjoy that taste, but I found it overwhelming and had to dilute the packet in over 1L of water to make it palatable.

Update September 2026: We’re currently developing Thrive Hydrate stick packs for convenient, travel-friendly single servings. They’ll use the same formula as the tub and are launching soon. The tub will remain the most cost-effective option, while the stick packs will offer a more convenient way to take Hydrate on the go.
