Sodii Supplements Australia

Sodii is an Australian electrolyte brand producing a single concentrated hydration formula – sodium, potassium and magnesium in ratios designed to reflect what the body actually loses in sweat. Minerals are sourced from Lake Deborah, a salt lake in Western Australia, rather than synthesised from industrial mineral compounds. The formula is built for everyday use – heat, exercise, travel and situations where fluid and electrolyte intake has been low.

The defining characteristic is sodium concentration. Sweat contains roughly four to five times more sodium than potassium, but most commercial hydration products lead with potassium, glucose, or both. Sodii centres sodium at a level that more closely mirrors actual sweat composition – making it a more precise tool for replacing real losses, not just adding electrolytes in a general sense.

Product Range Primary Application
Electrolyte Hydration Sodium, potassium and magnesium replacement for sweat loss, heat, exercise and travel
Key principle: Sodii leads with sodium because that is the electrolyte lost most heavily in sweat – the formula is built around sweat physiology, not around sports nutrition convention.

If you have not used Sodii before, the sample sachet is the practical starting point – same formula, no commitment. For regular use, the choice between the 30-pack sachets and the tub comes down to routine: sachets suit travel and portability, the tub is more cost-effective for home or desk use. The formula is identical across all formats.

Why shop Sodii at Fairfield Nutrition

We don’t stock everything – we stock what we’d use. Sodii products are stocked at Fairfield because the formulation is built around actual sweat physiology rather than sports marketing convention, and because Lake Deborah is a traceable, single-source Australian origin – not a blend of synthetic mineral salts with no clear provenance.

Most electrolyte products in this category differ only by flavour, sweetener type and branding. Sodii’s distinguishing characteristic is its sodium-to-potassium ratio – a deliberate formulation choice based on what sweat composition actually looks like, not what tastes most familiar or sells most easily. That kind of precision in a simple product is what earns a place in Fairfield’s range.

Everything ships from Melbourne. No international delays, no customs surprises. If something is out of stock, we tell you.
