REDMOND Re-Lyte Kids Hydration Electrolyte Mix Powder, Pink Lemonade 7.62 oz

Free Shipping

Why We Love It

Tangy, sweet flavor kids adore.
Hydration tailored for young bodies.
Clean ingredients parents can trust.

Main Highlights

TANGY SWEET LEMONADE. Classic lemonade gets a fruity, strawberry upgrade with Re-Lyte Kids Pink Lemonade! Tangy meets sweet in this refreshing treat that keeps you hydrated for epic adventures, from mastering math problems to ruling the playground. It's a winning combo that captures the fun flavor (and memories!) of summer any time of year.
SPECIFICALLY FOR KIDS. We partnered with pediatricians to develop Re-Lyte Kids with the specific hydration needs of little ones in mind. Each serving has a little less than half of the electrolytes you'd find in a serving of Re-Lyte Hydration. But it’s also a big hit with grown-ups who are just looking for a lighter, less salty hydration mix. With the same clean ingredients and essential electrolytes, it’s perfect for adults looking for gentler electrolyte levels and a little more sweetness.
WHO LIKES CRANKY KIDS? Kids can become dehydrated faster than adults. When kids sweat, they lose essential electrolytes like sodium, potassium, and magnesium. These electrolytes support energy, muscle function, focus, and even mood. Without the right balance, kids can quickly feel tired, unfocused, or just plain cranky. Re-Lyte Kids is designed to replenish these electrolytes, helping kids stay active, focused, and happy. Its formula is made specifically for young, growing bodies.
INGREDIENTS PARENTS CAN TRUST. Parents can trust Re-Lyte Kids' clean ingredients, since it is made with mineral-rich Real Salt, no added sugar or artificial dyes and uses real fruit and vegetable extracts for its vibrant colors.

Restores electrolyte balance quickly.
Contains seven essential vitamins.
Perfect for travel hydration.

Bursts with the juicy taste of ripe, freshly picked strawberries topped with decadent notes of whipped cream.
𝟳 𝗘𝘀𝘀𝗲𝗻𝘁𝗶𝗮𝗹 𝗩𝗶𝘁𝗮𝗺𝗶𝗻𝘀 𝗮𝗻𝗱 𝗠𝗶𝗻𝗲𝗿𝗮𝗹𝘀 – Includes B vitamins such as B3, B5, B6 and B12 that contribute to normal energy-yielding metabolism and to the reduction of tiredness and fatigue.

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.
