withinUs™ ReHydrate + TruMarine® Collagen contains 1g of functional organic cane sugar. 

The organic cane sugar in our electrolyte blend is solely for function.

The organic, Non GMO Project Verified cane sugar is used to optimize the absorption of electrolytes and water.

You may see sugar-free electrolyte blends on the market, but the absence of sugar makes them less effective in hydrating your body efficiently. A solution of water + glucose (sugar) + sodium (salt) hydrates your body better than water alone.

Each carefully selected mineral in withinUs ReHydrate + TruMarine® Collagen is included in citrate form. Citrate state minerals are proven to be more effective and bioavailable, and also work to control acidity in the body.

Hydrolyzed Marine Collagen (Ultra-Pure TruMarine® Collagen from wild caught fish scale), Sodium Chloride, Potassium Chloride, Calcium Citrate, Magnesium Citrate, Sodium Citrate, Potassium Citrate, Organic Cane Sugar, Citric Acid, Organic Tropical Flavour, Organic Rebaudiana Leaf

Finally found it!

I had searched for so long for an electrolyte with low sugar, and no artificial sweeteners. Plus the addition of collagen that is fairly low odor. This is an amazing product, and tastes great!

ReHydrate is a must for me during workouts, after a late night, while travelling and whenever Im feeling dry. I like the subtle taste and that it isn’t sweet. Great product!

I purchased this product just over a month ago and I just love it. Taste is great and actually makes me drink more water. Even others in my family are using it. Will definitely keep on purchasing.

Collagen love!

I use this every single day in my water bottle that I take to the gym. Love both flavours! And also love that this collagen is completely odourless. I tried collagen previously that made my water STINK. Never happens with WithinUs. I’ve been a dedicated WithinUs user for a few years now and I will never stray.

I love a scoop of the ReHydrate and Collagen in a glass of water after my workouts. It’s great for rehydration and I’m in love with the new Tropical flavour! I’ll even put in a glass of hot water before bed (it’s better than tea!).

I regularly use the ReHydrate before or after workouts and soccer matches. Not only has it helped me recover, it’s all-but-eliminated the cramps I used to suffer from afterwards. I regularly restock on withinUs products to make sure I don’t run out!


I can’t live without the Rehydrate.. as someone who has issues with getting enough water each day, and was dealing with brittle nails and hair from a hormonal disease, I was trying multiple products to combat those. I now keep a jar of Rehydrate on my desk at work, and at home, and feeling so much better, plus get so many comments I am looking younger and my hair is so healthy and shiny. This is now a life staple! Would love to try more products to incorporate into my daily routine!
