Electrolyte powder vs sports drinks

Sports drinks, electrolyte water, coconut water, tablets and powders all promise hydration. On the label they are very different. Here is how they compare on sodium, sugar and format.

The short answer

The biggest difference is sugar and sodium. Many sports drinks lead with sugar and carry modest sodium. Electrolyte powders tend to lead with sodium and carry little or no sugar. Electrolyte waters vary widely, and coconut water is naturally higher in potassium than sodium. Lula is an amino electrolyte powder: 1,000 mg sodium and 0.17 g sugars per scoop, no added sugar.

  • Sports drinks: usually sugar plus some salts. Built for taste and carbohydrate.
  • Electrolyte powders and tablets: usually more sodium per serving, less sugar. You add the water.
  • Compare per serving, and check whether a brand states minerals per serving or per litre.
The options

Five ways to get electrolytes in a drink

1. Sports drinks

The bottled drinks in the supermarket chiller. Most are built around sugar or other carbohydrate, flavour and some salts. That is deliberate: they are designed to deliver carbohydrate as well as fluid. It also means several grams of sugar per bottle, which is more than many people want in an everyday glass.

2. Isotonic drinks and powders

"Isotonic" describes concentration: a drink with roughly the same concentration of dissolved particles as the body's fluids. Most isotonic sports drinks get there with carbohydrate, so they are carbohydrate drinks first. Isotonic powders let you make the same drink yourself. More on the terms below.

3. Electrolyte water

Bottled water with minerals added. Some contain meaningful sodium; many add only small amounts for taste. Read the label per bottle before assuming it replaces much of what you sweat out.

4. Coconut water

Naturally contains potassium and smaller amounts of sodium, plus natural sugars. Cartons vary by brand and season, so check the label.

5. Electrolyte powders and tablets

A measured dose you add to your own water. Powders come in jars or sachets, tablets dissolve in a set amount of water. They usually carry more sodium per serving than sports drinks, and many have little or no sugar. Lula is an amino electrolyte powder in a jar.

The terms

Isotonic, hypotonic and hypertonic: what they mean

These words compare a drink's concentration with the body's own fluids. Concentration here means osmolality: how many dissolved particles, such as sugars and salts, are in each kilogram of water. Blood is normally about 275 to 295 mOsm/kg (StatPearls).

  • Isotonic: about the same concentration as body fluids.
  • Hypotonic: a lower concentration than body fluids. Plain water is the everyday example.
  • Hypertonic: a higher concentration than body fluids, for example drinks with a lot of sugar.

On a UK label, "isotonic" is a description, not a health claim. The authorised claims for sports drinks belong to "carbohydrate-electrolyte solutions", and they come with conditions: 80 to 350 kcal per litre from carbohydrate, with at least 75% of the drink's energy from high glycaemic carbohydrates such as glucose and sucrose, sodium of 460 to 1,150 mg per litre, and an osmolality of 200 to 330 mOsm/kg.

Isotonic powder or electrolyte powder?

An isotonic powder is a sports drink you mix yourself. Made up as its label directs, it is usually mostly carbohydrate with some salts, so it brings calories as well as electrolytes. Check the carbohydrate and sugars per serving on the label.

An electrolyte powder is built around minerals instead, with little or no carbohydrate. Lula is an amino electrolyte powder: one scoop has 1,000 mg sodium and 1.2 g of amino acids, with 0.17 g of sugars, 7.7 kcal and no added sugar. Lula does not claim to be isotonic.

Sugar

Why sports drinks contain sugar, and why Lula does not

In the classic oral-rehydration story, sodium is carried across the gut wall together with glucose, and water follows. That is why medical rehydration salts and many sports drinks pair sugar with salt. For long, hard efforts, carbohydrate is also fuel.

For an everyday glass, many people would rather skip the sugar. Lula has no added sugar and 0.17 g of sugars per scoop, from the natural peach, sweetened with stevia. Instead of sugar, we pair the electrolytes with 1.2 g of amino acids: taurine, glycine and alanine.

We list those amino acids as ingredients. We do not claim they make Lula hydrate faster or better. If you need carbohydrate on a long ride or run, take it separately, from food, gels or a carb drink. Our guides to electrolytes for runners and cycling cover how to keep the two apart.

Sodium

Sodium: the number to check first

Sodium is the electrolyte you sweat out most, which is why it leads every electrolyte formula. On the labels above, per serving, it ranges from 300 mg to 1,000 mg. Lula, LMNT and Puresport Ultra each state 1,000 mg.

Higher is not automatically better. It depends on how much you sweat and what else you eat. One scoop of Lula a day is the label dose. If you have been told to limit salt, speak with your GP first.

Format

Electrolyte powder or tablets?

Tablets are pre-portioned and dissolve in a fixed amount of water, often with a fizz. They are light and easy to carry. On the table above, Nuun Sport states 300 mg sodium per 5 g tablet.

Powder lets you choose the water and mixes without fizz. A jar has no single-use wrappers per serving. Lula is a 130 g glass jar, 20 scoops, 1,000 mg sodium each.

Neither format is more effective. It is about how much sodium you want per serving, the taste, and how you carry it. For sachets, sticks and tablets in more detail, see jar vs sachets and tablets.

DIY

What about a homemade isotonic drink?

A pinch of salt and a squeeze of citrus in water is a time-honoured DIY electrolyte drink, and many recipes add juice or honey for sugar. It works as a drink, but the dose is a guess every time, and without measuring you cannot know its concentration, so you cannot tell whether it is isotonic. A measured scoop gives you the same sodium dose, every glass.

Our guide homemade electrolyte drink vs powder has a simple recipe and the maths behind a pinch of salt.

Good to know

Questions, answered

Is electrolyte powder the same as a sports drink?

No. Many sports drinks lead with sugar and carry modest sodium. Electrolyte powders usually lead with sodium and carry little or no sugar. Compare the labels per serving.

What does isotonic mean?

It means a drink has about the same concentration of dissolved particles as the body's fluids. Hypotonic means lower; hypertonic means higher.

What is an isotonic drink?

A drink, usually a sports drink, made to about the same concentration as body fluids, mostly with carbohydrate plus some salts. Isotonic powders are the make it yourself version.

Is an isotonic powder the same as an electrolyte powder?

Not usually. An isotonic powder is a sports drink you mix yourself, and it is usually mostly carbohydrate with some salts. An electrolyte powder is built around minerals, with little or no carbohydrate. Lula is an amino electrolyte powder with 0.17 g of sugars per scoop and no added sugar. It does not claim to be isotonic.

Is Lula isotonic?

Lula does not claim to be isotonic. It is an amino electrolyte powder, not a carbohydrate drink: 7.7 kcal and 0.17 g of sugars per scoop, with 1,000 mg sodium. We have not published an osmolality figure for it.

Can you make an isotonic drink at home?

You can mix water, a pinch of salt and some juice or sugar at home. Without measuring, though, you cannot know the drink's concentration, so you cannot tell whether it is isotonic. Our guide homemade electrolyte drink vs powder has a simple recipe.

Which drinks are high in electrolytes?

Electrolyte powders, sachets and tablets usually carry the most sodium per serving. Sports drinks, electrolyte waters and coconut water vary widely. On the labels we checked on 20 October 2026, sodium ranged from 300 mg to 1,000 mg per serving.

What is electrolyte water?

Bottled water with minerals added. Some carry meaningful sodium; many add only small amounts for taste. Check sodium per bottle on the label.

Is electrolyte water worth it?

It depends on the label. Some bottled electrolyte waters add only small amounts of minerals for taste. Check sodium per bottle if you are replacing sweat.

Is coconut water a good source of electrolytes?

Coconut water naturally contains potassium and some sodium, plus natural sugars. Amounts vary by brand, so check the carton.

Does Lula have less sugar than sports drinks?

Lula has no added sugar and 0.17 g of sugars per scoop. Many retail sports drinks list several grams of sugar per bottle. Check the label you are comparing.

Does Lula hydrate better than water or sports drinks?

We do not claim that. Lula is an electrolyte drink for hydration. We make no claim that it hydrates better or faster than water or any other drink.

Electrolyte powder or tablets: which is better?

Neither is more effective. Tablets are pre-portioned and fizzy; powders let you choose the water and usually carry more sodium per serving. Pick the format and dose that suit you.

Does Lula contain caffeine?

No. Lula is not a pre-workout, and it has no caffeine.
