Sodii vs Thortz: An Australian Buyer's Comparison
Sodii and Thortz are both electrolyte brands available in Australia, but they are built for different jobs. Sodii is an Australian-made, sugar-free electrolyte blend designed for everyday hydration, keto and low-carb diets, sold in sachets and tubs. Thortz is a New Zealand-founded brand built specifically for endurance athletes, with effervescent tablets and a higher-sodium formula aimed at long training sessions and race day. If you want daily hydration, Sodii is the closer fit. If you are training for hours at a time and losing a lot of sodium through sweat, an endurance-focused formula like Thortz is worth a look. LYTES stocks the full Sodii range, Thortz is not currently part of our catalogue.
What is Sodii?
Sodii is an Australian electrolyte brand built around organic Australian lake salt, NASAA certified and HASTA tested. Its Everyday Hydration Salts range is formulated with zero sugar, which is why it's popular with people on keto and low-carb diets as well as anyone who just wants a straightforward daily electrolyte without added sweeteners. It comes in flavoured and unflavoured sachets and tubs, and LYTES stocks the full range.
What is Thortz?
Thortz is a New Zealand-founded sports nutrition brand best known for effervescent electrolyte tablets aimed at endurance athletes, think distance running, cycling and triathlon. Because endurance training and racing can mean hours of heavy sweating, Thortz formulates with a higher sodium content than most everyday electrolyte products, dropped into a bottle of water as a fizzing tablet rather than mixed as a powder. It isn't currently part of LYTES' catalogue.
How do the formulas actually differ?
The biggest differences come down to format and intended use rather than ingredients alone. Sodii is a powder, in single-serve sachets or a mix-at-home tub, dosed for everyday hydration and general low-carb or keto use. Thortz is an effervescent tablet, dosed higher in sodium to match what an endurance athlete loses through prolonged, heavy sweating during long sessions or races. Neither is "wrong", they're built to solve different problems: one for daily hydration, one for high-output endurance sport.
Format also changes how you'd actually use each one day to day. A Sodii sachet tips straight into a water bottle or glass, no fizzing or waiting, and a tub lets you measure out exactly as much or as little as you want per glass. A Thortz tablet needs to fully dissolve before drinking, which takes a minute or two, fine for a training bag or race belt where you're carrying tablets rather than a tub, less convenient if you just want a quick glass with breakfast.
Cost per serve is another practical difference worth knowing before you buy. Sodii's sachets and tubs are priced for daily, ongoing use, mixing into water you're already going to drink. Endurance-specific tablet formats like Thortz are typically priced and packaged around race and training kit budgets rather than everyday grocery-style hydration, so buyers are usually comparing them for a specific training block or event rather than as a year-round staple.

Which one suits you?
If you want a zero-sugar electrolyte for daily use, a keto or low-carb lifestyle, or general hot-weather hydration, Sodii's everyday dosing and Australian availability make it the simpler choice. If you're training for hours at a stretch and losing a lot of sodium through sweat, an endurance-oriented, higher-sodium product like Thortz is built specifically for that load. Not sure which format or flavour suits you yet? Start with a variety pack rather than committing to a full-size tub.
It's also worth saying these two categories aren't mutually exclusive. Plenty of people use an everyday electrolyte like Sodii for daily hydration and reach for a higher-sodium endurance product only around long sessions or race day. If your training load is genuinely heavy, ask whether you actually need endurance-level sodium every day, or only on the days that call for it, since that changes which product makes sense as your daily default.

Frequently asked questions
Is Sodii available internationally, or just in Australia?
Sodii is an Australian brand sold through Australian retailers, including LYTES, which means faster dispatch and no import wait compared with ordering an overseas brand.
Does Sodii contain sugar?
No. Sodii's Everyday Hydration Salts are formulated with zero sugar, which is why the range suits keto and low-carb diets.
What's the difference between a Sodii sachet and a tub?
They're the same formula. Sachets are pre-measured and convenient for on-the-go use, while a tub works out cheaper per serve if you're mixing at home.
Is Thortz suitable for everyday hydration, or only sport?
Thortz is formulated around the higher sodium losses of endurance training and racing, so its dosing runs higher than most everyday electrolyte products. It can be used day to day, but it's built with endurance athletes in mind first.
Can I try a few Sodii flavours before committing to a full tub?
Yes. The Salty Variety Pack includes a mix of flavours in single sachets, the easiest way to find a favourite before buying a bigger tub.
Can I use Sodii and an endurance-specific electrolyte like Thortz together, on different days?
Yes, plenty of people do exactly this, an everyday zero-sugar option like Sodii for daily use, and a higher-sodium endurance product on long training days or race day when sweat losses are much greater than usual.
