DIY Electrolyte Drinks vs. Store-Bought: A Lab Comparison
Your grandmother’s nimbu-paani is a better electrolyte drink than Gatorade — and costs 95% less. Here are the actual sodium, potassium, sugar, and cost numbers to prove it.
Key Takeaway
A homemade electrolyte drink — 6 teaspoons sugar, half a teaspoon salt, one lemon, 1 litre water — matches the WHO ORS formula and costs ₹3–5 per serving. Gatorade costs ₹50 for a bottle with 32g of sugar (8 teaspoons) and less sodium than your nimbu-paani. A family of four saves over ₹32,000 per summer by going homemade.
The 3 PM May Collapse
It is 3 PM in May. You have been in and out of the sun, your shirt is salt-crusted at the collar, and you feel that specific kind of tired where even sitting down does not help. You grab a glass of water. Then another. Still feel terrible.
That is because water replaces fluid but not the sodium and potassium your body sweated out. The average Indian adult loses 0.5 to 1.5 litres of sweat per hour in peak May heat. That sweat contains roughly 900–1,400 mg of sodium and 150–300 mg of potassium per litre. You can drink 3 litres of water and still feel dizzy because your blood sodium is dropping.
This is the moment every Indian reaches for something — a Gatorade from the fridge, an Electral sachet from the medicine cabinet, or the nimbu-paani their mother swears by. But which one actually puts back what your body lost? And which one is just overpriced sugar water in a sporty bottle?
We pulled the actual nutritional data from labels, WHO documents, and USDA food composition databases. The results are not close.
What Your Body Actually Loses in Sweat
Sweat is not just water. It is a saline solution carrying electrolytes your body needs for nerve signalling, muscle contraction, and maintaining blood pressure. When you sweat heavily and replace only the water, you dilute the remaining electrolytes in your blood — a condition called hyponatremia.
This is why marathon runners who chug plain water sometimes collapse. It is also why your dadi instinctively adds namak to your nimbu-paani — she may not know the word “hyponatremia,” but she knows the fix.
The WHO recognised this in 1978 when it developed the Oral Rehydration Solution formula. The reduced-osmolarity version (2003) is now the global standard: it uses a precise glucose-to-sodium ratio that exploits a co-transport mechanism in the small intestine, pulling sodium and water into the bloodstream faster than IV drips in mild-to-moderate dehydration. The Lancet called it “potentially the most important medical advance of the 20th century.”

Store-Bought Showdown: Electral vs Enerzal vs Gatorade
Electral ORS
Verdict: Matches WHO ORS formula exactly. Medical-grade. The correct choice for diarrhoea, vomiting, or heatstroke. Not tasty, but that is not its job.
Enerzal
Verdict: Has 5 electrolytes (adds calcium and magnesium) but heavy on sucrose. Better than Gatorade, worse than Electral. The middle child nobody talks about.
*Exact per-litre values not disclosed on label; estimated from ingredient order and serving data.
Gatorade
Verdict: Designed for American athletes sweating through 3-hour football practices. For a Delhi commuter, it is overpriced sugar water in a sporty bottle. 54g of sugar per litre is more than a glass of Frooti.
The DIY Contenders: Nimbu-Paani, Coconut Water, WHO ORS
Nimbu-Paani + Salt
The classic Indian answer to summer heat. High sodium from salt, vitamin C from lemon, and you control the sugar. Add kala namak for extra minerals and that distinctive flavour. Your nani was right.
Best everyday option
Coconut Water
Nature’s potassium bomb — 250mg per 100ml is higher than any commercial drink. Low calorie, zero additives. But sodium is moderate, so pair it with salty food for complete rehydration.
Best for potassium
Homemade WHO ORS
The exact WHO formula made at home. 6 level teaspoons sugar + ½ teaspoon salt + 1 litre boiled-and-cooled water. Medically validated. Used by UNICEF globally. Costs less than a toffee.
Best for medical dehydration
The Sugar Problem Nobody Mentions
A single 500ml Gatorade contains 32g of sugar — that is 8 teaspoons. The WHO recommends no more than 25g of added sugar per day. One bottle puts you at 128% of your daily limit before you have eaten anything. Enerzal is marginally better but still sugar-heavy. If you drink two servings a day through summer, you are consuming the sugar equivalent of 3 extra rotis daily — purely from your “health drink.”
Why Sports Drinks Get Away With It
Gatorade was invented in 1965 for the University of Florida football team. Those players were sweating through 3–4 hours of intense training in Florida humidity, burning 3,000+ calories per session. For them, 54g of sugar per litre was fuel, not excess.
But in India, Gatorade is sold to office workers, college students, and weekend cricketers — people who need electrolytes but absolutely do not need 54g of sugar per litre. The marketing shows athletes. The consumption is mostly by people sitting in air-conditioned rooms who had one sweaty auto ride.
Electral uses dextrose (glucose) instead of sucrose, which is medically intentional. Glucose aids sodium absorption through a co-transport mechanism in the small intestine — this is the science behind ORS. But for everyday summer hydration, you do not need the full medical dose. Halve the sugar to 3 teaspoons per litre and you still get the transport benefit with half the glycaemic load.
Your ₹5 Summer Recipe (Two Versions)
Two recipes: one for medical-grade rehydration (diarrhoea, heatstroke, fever) and one for everyday summer hydration (office, commute, workout). The everyday version tastes better because it has less sugar and more lemon.
Medical-Grade ORS (WHO Formula)
Boil 1 litre of water and let it cool completely
Add 6 level teaspoons of sugar (about 13.5g)
Add ½ level teaspoon of table salt (about 2.5g)
Stir until fully dissolved. Do not add lemon (acid can interfere with medical ORS)
Sip slowly — 200ml every 15 minutes. Make fresh every 24 hours.
Cost: ₹2–3 per litre
Everyday Summer Nimbu-Paani
Take 1 litre of cold water (filtered or boiled-and-cooled)
Add 3–4 teaspoons of sugar (half the medical dose)
Add ½ teaspoon table salt + a pinch of kala namak
Squeeze in 1 full lemon (adds potassium + vitamin C + flavour)
Optional: pinch of sendha namak for extra minerals, or jeera powder for digestion
Refrigerate. Make fresh daily — do not store more than 24 hours.
Cost: ₹3–5 per litre
