LMNT Watermelon Salt brings a deliciously sweet and salty twist to your water, making every sip a refreshing treat. Try it with sparkling water and a squeeze of fresh lime, or add mint and a slice of watermelon for a cool, flavourful boost. Perfect for post-workout, summer days, or whenever you need a tasty refresh.

LMNT was founded by Robb Wolf to meet a critical need for a clean, high-sodium, zero-sugar electrolyte drink. After years on a low-carb diet, Robb realised that his performance was lacking due to insufficient salt intake. Popular products were filled with sugar and low on electrolytes, so he created his own formulation. LMNT was born from this journey, offering an effective product that has since helped thousands optimise their health by addressing the often overlooked importance of proper electrolyte balance.

While these zero-sugar sachets are a cleaner choice than most regular electrolytes, their natural flavourings do contain maltodextrin. As part of our Community Testing, we used glucose monitors to determine whether LMNT doses can be considered ketogenic-friendly — and we’re happy to confirm they can. With their 'more salt, not less' approach, they are a top choice for fuelling your body with the minerals it needs to function best.
