Electrolyte powders, decoded
Updated 11 August 2026 · VegEco editorial desk
Standard LMNT electrolyte drink mix does not contain caffeine — its unflavoured and flavoured sticks are sodium, potassium and magnesium with no stimulant. The brand has sold a separate caffeinated line, so check the specific product name on the sachet. Across the category, the questions that matter more are how much sodium a serving carries, whether you need it at all, and whether the flavouring and colouring are plant-based.
What to look for
- Sodium per serving
- High-sodium formulas carry around 1,000 mg per stick — appropriate for endurance sessions, heat work or heavy sweating, and excessive for a desk day.
- Do you need one?
- For everyday hydration, water and normally salted food cover electrolyte needs. Powders earn their place past roughly an hour of hard sweating, in heat, during illness with fluid loss, or on very low-carbohydrate diets.
- Sugar or no sugar
- Sugar-free formulas suit low-carb and fasting use. During long endurance efforts, some carbohydrate actually improves fluid absorption and performance.
- Vegan check
- Look at the colours (carmine in reds), any capsule shell (gelatin), and added vitamin D (D3 is usually lanolin-derived unless labelled lichen-sourced).
- Cost versus DIY
- A quarter-teaspoon of salt, a pinch of potassium salt and a squeeze of citrus in 500 ml of water reproduces most of the formula for pennies.
Matching the format to the situation
High-sodium sugar-free sticks
Best for Endurance training, heat, keto
Replaces the sodium lost in heavy sweat without added sugar.
Watch out: Too salty and unnecessary for sedentary days; watch total daily sodium.
Balanced low-sodium tablets
Best for General daily use and travel
Modest sodium and potassium, easy to carry, no measuring.
Watch out: Check the tablet is not gelatin-coated and colours are plant-based.
Carbohydrate + electrolyte mix
Best for Sessions over 90 minutes
Glucose co-transport speeds sodium and water absorption and supplies fuel.
Watch out: Not suited to fasting or low-carb protocols.
Unflavoured powder
Best for Adding to food or squash you already like
No sweeteners, no colours, nothing to check on the flavouring.
Watch out: The salt hit is undisguised — dilute more than you expect.
DIY salt and citrus
Best for Cost-conscious everyday hydration
1/4 tsp table salt, a pinch of potassium chloride and lemon in 500 ml is a functional oral rehydration base.
Watch out: Not a substitute for medical oral rehydration solution in serious illness.
Coconut water
Best for A whole-food option after moderate exercise
Naturally potassium-rich with some sodium and carbohydrate.
Watch out: Low sodium relative to sweat loss — add a pinch of salt for hard sessions.
Frequently asked questions
Does LMNT have caffeine?
The standard LMNT Recharge electrolyte drink mix contains no caffeine. The company has offered a separate caffeinated product line, so read the specific sachet or product page before assuming.
Are electrolyte powders vegan?
Most are, since the minerals are inorganic salts. Check red and pink flavours for carmine, tablets for gelatin, and any added vitamin D3 for a lichen (vegan) source.
Is 1,000 mg of sodium per serving too much?
It depends entirely on sweat losses. It is reasonable during prolonged exercise or heat exposure and excessive as a routine daily addition for most people, especially with high blood pressure.
Do I need electrolytes on a plant-based diet?
Plant-based diets tend to be high in potassium and magnesium and often lower in sodium. If you train hard and cook without much salt, a modest electrolyte addition around sessions can help.
