Why Regional Isotonic Drinks Matter More Here Than Elsewhere
In most Western running markets, isotonic and electrolyte drinks are a specialty-store purchase. Across Southeast Asia, the opposite is true: brands like 100Plus, Isoplus, and Sponsor are convenience-store staples that have been part of daily life for decades, which means they're almost always the easiest hydration option available on the actual day of a race -- at the finish-line table, the corner shop near your hotel, or the aid station itself.
That availability matters more than brand loyalty. A runner who trains with an imported electrolyte brand but can only find a regional one at a race in a smaller city is better off knowing what these local drinks actually contain and how they compare, rather than discovering the difference mid-race.
Malaysia and Singapore's 100Plus
100Plus has been Malaysia and Singapore's dominant isotonic drink since 1983, when F&N launched it to mark the company's 100th year in Asia -- it's been voted the top isotonic brand in both markets repeatedly since. It's officially endorsed by Malaysia's National Sports Council and has sponsored elite athletes across multiple sports, which is part of why it's the drink handed out at so many regional races.
The original carbonated formula and the newer 100PLUS Active (non-carbonated) cover slightly different preferences -- carbonation isn't ideal mid-run for most people, so Active is the better pick to actually drink while moving, with the original better saved for post-race.
Indonesia's Isoplus and Strive-Adjacent Nutrition
Isoplus, made by Indonesia's Wings Food, is one of the country's dominant isotonic brands alongside Pocari Sweat, built around a 7-ion formula and sold in small, race-friendly 350ml bottles. Wings has leaned further into running specifically with the Isoplus Run event series, which is as clear a signal as any that the brand sees runners as a core audience rather than an afterthought.
Indonesia is also home to Strive, generally credited as the country's first locally-produced energy gel -- worth knowing about even in a hydration-focused list, since pairing a local isotonic drink with a local gel is a genuinely all-Indonesian fueling strategy for anyone racing there.
Thailand's Sponsor and the Region's Pocari Sweat
Sponsor has been Thailand's leading sports drink for more than 30 years, made by TCP Group (also behind the original Thai formula that became Red Bull) and used as the official drink of the Thai national football team. Its newer Sponsor Isotonic line specifically targets the lower-sugar, quick-refresh profile that suits endurance activity better than the classic formula.
Pocari Sweat deserves a mention across the whole region rather than one country -- while the brand originates with Japan's Otsuka Pharmaceutical, it's manufactured and marketed so heavily across Indonesia, Malaysia, Singapore, and beyond that it functions as a de facto regional staple, sold in both ready-to-drink bottles and travel-friendly powder sachets.
