Homemade Electrolyte Drink: A Precise g/L Recipe with Canadian Ingredients

Search for a homemade electrolyte drink recipe and you'll find the same vague instructions everywhere: "a pinch of salt, a squeeze of lemon, a spoonful of honey." That's a lemonade, not an electrolyte formulation. If you sweat through training sessions, work outdoors in the summer, or simply want to stop paying premium prices for flavoured salt water in single-serve pouches, you can mix a proper electrolyte drink yourself — with a scale, four or five ingredients, and exact grams-per-litre dosing.

This guide gives you a precise, repeatable formula using citrate salts, the same forms used in commercial hydration products. All ingredients are available in Canada, shipped from Quebec, so no cross-border orders or currency conversion.

TL;DR: A basic homemade electrolyte drink uses roughly 6 g of salts and sugar per litre: 2.5 g sea salt, 1 g potassium citrate, 0.5 g magnesium citrate, 30 g sugar and 1.5 g citric acid. A Light version uses half the salts; an Intense endurance version raises carbohydrates to 60-80 g/L with a 2:1 maltodextrin-to-sugar blend.

Why citrates instead of table salt?

You could build an electrolyte drink from table salt (sodium chloride) alone, but citrate salts have real advantages for a drinkable formulation:

• Taste: sodium chloride tastes aggressively salty at effective doses. Sodium citrate delivers the same sodium with a milder, slightly tangy profile — the reason it's the base of most commercial hydration mixes.
• Solubility: citrates of sodium, potassium and magnesium dissolve readily in cold water. Some other mineral forms (oxides, carbonates) sink to the bottom of the bottle.
• Buffering: citrate buffers acidity, letting you add citric acid for a bright taste without making the drink harsh.

What are the five ingredients?

• Sodium citrate — your main sodium source. Sodium is the electrolyte lost in the largest amounts through sweat.
• Potassium citrate — the second electrolyte, lost in smaller amounts than sodium.
• Magnesium citrate — smaller amounts still; a well-tolerated, soluble form at drink-level doses.
• Sugar (sucrose) or dextrose — carbohydrate is a standard component of oral rehydration-style formulas; it also sets the sweetness and contributes to the osmolality of the finished drink. Maltodextrin works too if you want lower sweetness at the same carb load.
• Citric acid — for taste. Without it, the drink tastes flat and slightly soapy. With it, it tastes like a sports drink.

Optional: coconut water powder adds natural potassium and a pleasant flavour base.

What is the formulation table per litre of water?

Two profiles: Light for everyday hydration or moderate activity, and Intense for long or hot training sessions with heavy sweating.

Elemental values are approximate — the exact sodium, potassium or magnesium content per gram depends on the specific salt form and hydration state of your powder. Check the certificate of analysis (COA) of your batch for precise numbers.

For scale: one litre of the Intense profile contains roughly the sodium of a large restaurant meal — useful context when you set your sodium target and run a taste panel on the formula.

How do you prepare it step by step?

1. Weigh, don't scoop. A pocket scale with 0.01 g precision costs about the same as two tubs of commercial electrolyte mix. Volume measures (teaspoons) are unreliable for powders of different densities.
2. Dissolve the citrates first in a small amount of warm water — they dissolve faster than in cold.
3. Add sugar and citric acid, then top up to 1 L with cold water.
4. Taste and adjust the citric acid in 0.25 g increments. Flavour is personal; electrolyte content is not — keep the salts as dosed.
5. Refrigerate and use within 48 hours, since the mix has no preservatives.

Make a dry concentrate instead

Multiply the recipe by 20, blend the powders thoroughly in a sealed container, and weigh out ~24 g (Light) or ~56 g (Intense) per litre when needed. Store the blend airtight — citric acid and citrates are hygroscopic and will clump in humid conditions.

What are the common mistakes?

• Too much magnesium. Magnesium citrate carries a distinct bitterness and is the first ingredient to unbalance the taste profile. Stay near the table values; more is not better.
• Skipping carbohydrate entirely. Zero-sugar versions are fine on taste, but carbohydrate is part of the classic oral rehydration composition. If you want low-calorie sweetness, a tiny amount of sucralose handles the taste while you keep 5–10 g/L of dextrose in the formula.
• Eyeballing potassium. Potassium is the one to treat with respect. Follow the dosage, and if you have kidney issues or take medication affecting potassium levels, talk to a healthcare professional before using any electrolyte product — homemade or commercial.
• Using bath-grade Epsom salt or other non-food powders. Only use food-grade (FCC/USP) ingredients with a COA. Our guide on buying food-grade bulk ingredients in Quebec explains what to check.

What is the honest cost per serving?

Single-serve electrolyte pouches commonly retail between $1 and $2.50 per portion in Canada. Mixed from bulk ingredients, a litre of the Light profile uses under 25 g of powder total — a few cents of citrates and citric acid plus the sugar. Even accounting for the scale and your time, the per-portion cost drops by an order of magnitude, and you control exactly what's in the bottle: no dyes, no flavour system you didn't choose, no "proprietary blend."

How do businesses go from kitchen recipe to product?

If you're a gym, a sports team, a juice bar or a beverage startup, this same formulation logic scales linearly: g/L becomes kg per 1,000 L. All the ingredients above are available by the kilogram, in 1 kg to 25 kg formats, with B2B pricing, shipped across Canada. Note that commercially sold electrolyte beverages in Canada may fall under Health Canada's supplemented foods framework depending on composition and claims — factor labelling requirements into your product plan before launch.
