1g funcional sugar (glucose);

withinUs™ ReHydrate + TruMarine® Collagen contains 1g of organic cane sugar solely for functional purposes, which is almost 20 times less than the conventional sports drink. Glucose is the most common form of sugar and is used in the body for energy. Glucose enhances sodium and water transport across the upper intestinal wall and into the bloodstream. The organic, Non-GMO Project Verified cane sugar in ReHydrate + TruMarine® Collagen is used to optimize the absorption of electrolytes and water, hydrating the body better than water alone. Without the 1g of functional sugar, our body would not be able to adequately absorb and metabolize the minerals and nutrients.

How to enjoy ReHydrate + TruMarine® Collagen

Add 1 stick pack of withinUs™ ReHydrate + TruMarine® Collagen to your water daily - during or after exercise, while travelling, or after being in the heat/sun to hydrate your body completely. ReHydrate can also help prevent and speed up recovery from illness, aid lean muscle gain, and help reduce joint pain. 

Frequently Asked Questions

Is drinking water just as effective as taking an electrolyte?

No. Drinking water alone when you are already dehydrated will actually cause further dilution of electrolytes in your body, and potentially a complete depletion of electrolytes causing further dehydration.

Consuming electrolytes prevents dehydration, not only because of the water it provides but also because the electrolytes stimulate your body to hold onto water. When you are exercising, or outside on a hot day, getting enough fluid is vital for keeping your body temperature down, and if you are an athlete, being hydrated is essential for optimal performance.

Why is sugar included in ReHydrate + TruMarine® Collagen?

Glucose is the main fuel source for the body and needs to be replenished after dehydration in order to help the body restore balance and recover. The 1g of organic cane sugar per serving included in ReHydrate + TruMarine® Collagen serves a functional role enabling the electrolytes to be absorbed into your body quickly and efficiently.

Can children take ReHydrate?

withinUs™ ReHydrate + TruMarine® Collagen has been formulated with organic, Non-GMO ingredients and the best absorbed electrolyte minerals sodium, potassium, calcium, magnesium and chloride. Our current recommended daily serving is based on adult consumption (up to 4x per day). The amount of sugar is far less than conventional sports/electrolyte drinks on the market. Children are not advised to consume the product in the same quantities as adults but can absolutely find benefit in our ReHydrate + Collagen. 1 stick pack of ReHydrate should suffice, however, please consult your healthcare practitioner prior to use if there are any additional questions or medical concerns.

    I got Rehydrate at Costco last week. I love it! I use it daily. It is a great drink after a spin session, weight workout or afternoon snowshoeing outing. I will be purchasing more of this!
