The Func. Lab Salty Electrolytes: Ingredients, Sodium and Price

What are the ingredients in The Func. Lab Salty Electrolytes?

The Citrus label lists seven ingredients, in this order: edible common salt, magnesium gluconate, tartaric acid, citric acid, stevia (INS 960), silicon dioxide and natural citrus flavour. Indian labels list ingredients by descending weight, so the order itself is information — salt, the sodium source, comes first.

Each one has a visible job on the panel. Salt supplies the 1,000 mg of sodium. Magnesium gluconate supplies the 70 mg of magnesium. Tartaric and citric acid give the drink its tartness. Stevia sweetens it without sugar, which is how the panel shows 0 g. Silicon dioxide is an anti-caking agent that keeps the powder free-flowing, and the citrus flavour is the Citrus variant’s name ingredient.

One thing on the panel has no counterpart in the list: the label declares 210 mg of potassium, but no potassium source — no potassium chloride, citrate or gluconate — appears among the seven ingredients. The potassium is real: the brand’s own July 2025 Eurofins report on the Citrus batch finds 41,300 mg/kg, which is 231 mg in a 5.6 g sachet (lab reports). So the discrepancy is with the ingredient list, which is incomplete, not with the panel figure. The tub’s back panel (read 17 August 2026) lists the same seven ingredients, worded “Salt” and “Stevia” without the INS number.

How much sodium is in Func Lab Salty Electrolytes?

1,000 mg per 5.6 g sachet, supplied by edible common salt, the first ingredient on the label. That places it at the top of this database: of the 23 products that declare a numeric sodium figure, only Unived Daily Hydration declares more, at 1,020 mg, while UP&RUN Advance and Unived Elite Hydration Mix also declare 1,000 mg. Two of the 1,000 mg sachets are sugar-free — Func Lab and UP&RUN Advance — and Func Lab is the cheaper of the pair at ₹29.67 a serving against ₹36.60.

The tub says to mix a sachet into 400–600 ml of cold water (the nutrition panel itself gives no volume). That makes the drink 1,667–2,500 mg of sodium a litre, depending on which end of the range you pour.

Is The Func. Lab Salty Electrolytes an ORS?

No. WHO-formula oral rehydration salts are defined by the pairing of glucose with sodium, and Salty Electrolytes carries no glucose — its panel declares 0 g sugar and stevia as the sweetener. It is an electrolyte drink mix, not an ORS.

The contrast with Electral, the reference WHO-formula ORS in this database, is visible on the two labels:

	Func Lab Salty Electrolytes	Electral ORS
Sachet	5.6 g in 400–600 ml (tub)	21.80 g, made up to 1 litre
Glucose	none (0 g sugar)	13.5 g dextrose anhydrous
Sodium declared as	1,000 mg per sachet	75 mOsmol/L

The two sodium declarations are not directly comparable: Electral’s label states a molarity for a fixed one-litre dilution, while Func Lab states milligrams a sachet with a 400–600 ml range on the tub. We print each as its label gives it rather than converting one into the other. For how the two formats differ as a class, see ORS vs sports drinks and the Electral page.

Is Func Lab Salty Electrolytes sugar-free?

Yes, by its own panel: 0 g total sugar and 0 g added sugar, alongside 2 g of carbohydrate and 9 kcal per sachet. Sweetness comes from stevia (INS 960), a non-caloric sweetener, so nothing in the sweetening contributes sugar.

Our sugar-free category admits any product declaring 0.1 g of total sugar or less per serving; Func Lab clears that cut-off at a flat 0. The practical difference between this and a sugared mix is one of format: with no glucose in the sachet there is no glucose–sodium co-transport in play, which is the mechanism sugared sports drinks and ORS are built around. Which format suits a given run is a question for your own numbers, not this page.

Is there an unflavoured Func Lab electrolyte?

Yes. Unflavored is one of the seven listed flavours, alongside Citrus, Orange, Raspberry, Pineapple, Berry Blast and an Assorted pack.

One caveat, and it applies to every number on this page: our panel is transcribed from the Citrus label only. The unflavoured variant’s own panel has not been read, so we do not claim its figures are identical — flavour variants of the same product do sometimes differ. The other unflavoured electrolyte powder in this database is Sharrets, a different shape entirely at 347 mg sodium per scoop.

What does Func Lab Salty Electrolytes cost per serving?

On amazon.in a pack of 15 sachets sells at ₹445, which is ₹29.67 a serving; at the printed MRP of ₹500 it is ₹33.33. The brand’s own site lists 15 sachets at ₹449 and 30 at ₹869. Prices were checked on 6 August 2026 and change often — treat the date as part of the number.

Within this database’s per-serving spread — ₹9.73 for Carbamide Forte’s effervescent tablets at the cheap end to ₹135.00 for Liquid I.V. Sugar Free at the dear end, across the 40 products with a numeric per-serving price — ₹29.67 sits in the middle band. The fuller picture, including what each rupee buys in declared sodium, is on the price-per-serving page.

Is Func Lab Salty Electrolytes worth buying?

As a label-fact verdict rather than an endorsement: ₹29.67 a serving buys the equal-highest declared sodium in this database (1,000 mg), with 0 g sugar and only 9 kcal — and among the sugar-free sachets at that sodium level it is the cheapest. That shape suits sessions where sweat loss is the point of the purchase; it is a lot of sodium for casual sipping through the day.

Two caveats. The declared 210 mg of potassium has no named source in the ingredient list — the brand’s 2025 lab report finds it, so the list is what is short, not the powder. And the brand’s most recent published Citrus report (Eurofins, July 2026) measures 678 mg of sodium a sachet against the 1,000 mg declared; the July 2025 report measured 969 mg. One sample each — see the lab reports section for every published figure.

Buyers on amazon.in rate it 4.4 from 101 ratings (ASIN B0FQ59G1RG, read 6 August 2026).
