𝗬𝗘𝗦, 𝗜𝗧'𝗦 𝗦𝗔𝗟𝗧𝗬❗ - 𝗕𝗘𝗖𝗔𝗨𝗦𝗘 𝗜𝗧'𝗦 𝗘𝗙𝗙𝗘𝗖𝗧𝗜𝗩𝗘 – Water is essential but often falls short in replenishing your body. Most electrolyte sachets or tablets lack the necessary levels of salt to replenish your body, and some even contain high levels of sugar - this is in contrast to Free Soul Hydrate which contains an advanced salt formulation, with zero sugar inclusion.
𝗧𝗛𝗜𝗡𝗞, 𝗙𝗘𝗘𝗟 & 𝗣𝗘𝗥𝗙𝗢𝗥𝗠 𝗔𝗧 𝗬𝗢𝗨𝗥 𝗕𝗘𝗦𝗧 – Dehydration causes a range of different issues, but water alone isn't enough to replenish essential minerals. Hydrate delivers an advanced electrolyte blend with Sodium, Potassium, Magnesium, Vitamin C, Calcium, and Zinc in a delicious lemon and orange twist.
𝗡𝗢𝗧 𝗢𝗡𝗟𝗬 𝗙𝗢𝗥 𝗣𝗢𝗦𝗧-𝗪𝗢𝗥𝗞𝗢𝗨𝗧 – Dehydration can happen for various reasons, not only during a workout. Electrolytes are commonly included in hydration products, and staying hydrated can support overall wellness, whether before the gym, after a run, or as part of a daily routine.
𝗡𝗨𝗧𝗥𝗜𝗧𝗜𝗢𝗡𝗜𝗦𝗧 𝗙𝗢𝗥𝗠𝗨𝗟𝗔𝗧𝗘𝗗 – Unlike other electrolyte powders & tablets, our electrolytes are free from sucralose, colouring, artificial flavours, and added sugar. Each sachet is loaded with goodness — 1,000mg of Sodium, 300mg of Potassium, 70mg of Magnesium, 40mg of Vitamin C, 52mg of Calcium, 2.5mg of Zinc and absolutely Zero Sugar!

Why We Love It

Zero sugar, clean formula.
All six essential electrolytes.
Hydrates 4X more effectively.

Main Highlights

The Humantra Difference - Keeping your body properly hydrated is one of the most important things you can do for your health. After realizing that most electrolyte formulas are loaded with sugar and gut-disrupting artificial ingredients, and only contain a few of the 6 essential electrolytes, we set out to create a best-in-class electrolyte powder that also tastes amazing.
Built for Everyone - Whether you’re an athlete looking for peak performance or a newbie who wants to experience the energy and clarity of being well-hydrated, optimum hydration is the #1 starting point that you need to address.
Zero Sugar, Clean, Complete, and Effective - Our plant-based, sugar-free electrolyte and antioxidant drink mix with all 6 essential electrolytes and 100% natural ingredients. It’s a completely CLEAN, artificial-free formula that won’t disrupt your gut and hydrates 4X more effectively than water alone.
6 Essential Electrolytes - There are 6 essential electrolytes—and our bodies need all of them. Most hydration support brands and leading sports drinks are incomplete, only containing 2 to 4 per formula. We've created a complete electrolyte powder formula with all 6 electrolytes to hydrate you 4X more than leading sports drinks.
Our Mantra - We never take shortcuts. You’ll always get exactly what you need and nothing that you don’t. And we’ll never use artificial ingredients or fillers. Every Humantra formula is made with your health in mind, with the highest quality standards in the industry.
