The Marketing Claim & The Catch
A typical 30 sachets (180 g total) pack of LMNT Electrolyte Drink Mix is about £42.00 in wellness & supplements. That is a snapshot, not a live Amazon price — listings, sizes and deals move. The marketing line is that you are buying a finished lifestyle product, not a weighed chemical.
On the pack: Zero sugar clinical electrolyte ratio; and 1,000 mg sodium, 200 mg potassium, 60 mg magnesium per pack.
The catch: Costs over £1.40 per sachet for about £0.06 worth of common mineral salts. Food supplement comparison, not medical advice.

- “1,000 mg sodium, 200 mg potassium, 60 mg magnesium per pack”
Proprietary Blend & Dosage Breakdown
The labelled active is Sodium chloride, potassium chloride, magnesium malate at 100%. Everything else in the pack is citric acid, stevia and natural flavours.
Even when the pack is sold as “pure” or ready-to-use, the dose that actually does the work is Sodium chloride, potassium chloride, magnesium malate. The rest is how they get it into a bottle you will pick up.
This is a food-supplement comparison, not a medicine. Proprietary blends, gummies and resins make it hard to see milligram-level doses. The teardown below uses the labelled active and a bulk equivalent you can weigh or capsule yourself.

Active ingredient and cheaper alternative — FAQ
What is the active ingredient in LMNT?
LMNT Electrolyte Drink Mix is labelled as Sodium chloride, potassium chloride, magnesium malate at 100%. The carrier is Citric acid, stevia and natural flavours. Pack size: 30 sachets (180 g total). The bulk equivalent we index is DIY high-potency electrolyte raw stack (CAS 7647-14-5 / 7447-40-7).

Used at the listed working strength (2.5 g fine rock salt (1,000 mg Na) + 380 mg potassium chloride (200 mg K) + 400 mg magnesium malate (60 mg Mg) in 750 ml water), the dupe is the same chemistry as the branded pack for food-supplement use as labelled — not as a medicine. That is not a blanket all-clear: read the supplier SDS, wear the listed PPE, keep acids away from hypochlorite, and follow UK HSE/COSHH rules. Wellness teardowns are supplements, not medicines.
