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 + 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. 

Sodium - Regulates water in the body. It also plays an important role in maintaining the healthy function of muscles and nerves, and helps control blood pressure levels.

Potassium - Is important for regular digestive and muscular functioning in the body, and is vital for healthy heart function. Potassium enables our cells to absorb more water, therefore keeping the body hydrated.

Magnesium - Is essential for healthy immune system functioning. Magnesium helps increase bone strength and also helps the heart beat rhythmically by allowing it to relax between beats. Deficiency is common and can affect overall mood.

Calcium - Is responsible for many functions such as nerve transmission, muscle growth and contractions and ensuring a regular heartbeat. Calcium deficiency can result in the body taking calcium from the bones, resulting in weakened bones, and muscle cramps.

Chloride - Works with Potassium and Sodium to help balance acids in the body. Chloride aids the movement of fluid in and out of cells, and helps muscles contract effectively, and also keeps tendons and joints healthy.

withinUs TruMarine® Collagen - An Ultra-Pure, Premium-Select Grade marine collagen peptide. Provides the 3 amino acids essential for collagen production in the body - important for lean muscle gain, muscle recovery, reducing joint pain, and increasing overall health

Amazing product

I have been using this everyday to keep my hydrated for three years now- I love it! And my skin looks fantastic.

After 2 weeks my nails are so healthy and strong and my hair grows in thicker. I also love drinking this before bed as the magnesium in it relaxes me a bit but it’s good any time of day. Not gonna lie, I don’t like the taste but if I mix it with tea and more lemon, you can’t taste it at all. Very easy to digest as well. No upset stomach.

Perfect blend

I have tried many other brands of hydration mixed and this is hands down my favourite! The flavour is subtle, and it mixes so easily! This is now my new go-to for daily hydration.

Cannot live without….

I started using Rehydrate and LOVED it and my husband was so confused… until he tried it! Now he is a daily user as well and will remind me when it’s time to order more and has the individual packets on his desk at work. There is a noticeable difference in reduced thirst and energy levels immediately after consuming! It’s also been helping my postpartum hair regrowth and my skin has never looked better!

Just buy it!

This is one of my favourite products from withinus! It’s amazing in the summer when you need a boost on a hot day, so refreshing and hydrating!!
I take it now in the winter while breastfeeding to stay hrydrated and it makes me feel great!

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!).

Bradley Smith

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!
