The Format Tradeoff
Sachets are convenient - one packet, one bottle, no measuring. Tubs require a scoop but offer dramatically better cost-per-serve. Australian pricing in mid-2026 shows the gap clearly: sachet single-serves often cost 3-5× per serve compared to the equivalent dose from a tub of the same brand.
Real-World Numbers
A 30-serve tub of Dr.Hydrate at brand-direct pricing comes out to roughly $1.50-$2.00 per serve. The same brand's sachet packs come closer to $3-$4 per serve. Staminade tubs at Coles/Woolworths sit around $0.50-$0.70 per serve. LMNT single-serve sachets are roughly $2.50-$3.50 per sachet depending on bulk and shipping.
Why You'd Pick Sachets Anyway
The convenience math is real. A sachet in a bag for travel, a single-serve at the gym, or a precise-dose option for someone tracking electrolyte intake all justify the premium. Sachets also pack flat for backpacks, suitcases, and pockets.
Hybrid Buying
A common pattern: a tub at home for daily use plus a small pack of sachets for travel, gym days, or hot training. This optimises for both cost and convenience.
The Direct-to-Consumer Edge
Australian DTC brands like Bulk Nutrients and True Protein tend to offer the lowest cost-per-serve through their bulk-bag SKUs. Subscribe-and-save options shave further. If price-per-serve matters and you're using a product regularly, DTC bulk is the lever.
Frequently Asked
Are sachets worth the extra cost?
For travel and gym-bag portability, often yes. For at-home daily use, a tub is dramatically cheaper per serve. Many people own both formats of the same brand.
What's the cheapest electrolyte product per serve in Australia?
Supermarket-channel tubs (Staminade) and direct-to-consumer bulk bags (Bulk Nutrients) sit at the low-cost end - often under $1 per serve.
Why are sachets so expensive?
Sachet packaging costs more per serve than bulk tubs. Some sachet brands also use premium ingredients (high sodium, niche sweeteners) that add to the cost.
