Raw Replenish Box

Electrolyte Formula


Sodium plays a number of important roles in your body:

* Aids in the absorption of nutrients in your gut
*  Helps maintain cognitive function
*  Helps maintain nerve impulse transmission and muscle contraction
*  Increases blood plasma volume
* Helps maintain a fluid balance in your body

The more blood you have, the less strain on your cardiovascular system as it works to deliver oxygen to your muscles and helps to dissipate heat to cool you down when you’re working hard. 

So yes, sodium is very important if you want to maintain your performance when it counts.

Many studies have shown that on average, athletes are losing 1000mg of sodium per 1 liter or 32 oz of sweat lost, with many athletes tested in the lab showing a loss upwards of that number. 

Because of this, athletes need to know and then replenish their sodium losses throughout their training and racing to keep their body functioning optimally. 

We chose 1000mg of Sodium per serving, because for most athletes, that is the minimum they need to replace per hour. 

We chose Sea Salt because it's less processed and contains more minerals than your regular salt. It is made up of 84% chloride, 16% trace minerals

We chose Sodium Citrate as it makes the solution taste less salty, and combined with our other sodium choice it will act as a mild buffer, reduce chloride atoms that sit in the gut and will lower the osmolarity of the solution you are drinking. 

Replenish will allow you to replace your sodium needs while keeping your gut and taste buds happy

Electrolytes, in particular sodium, is critical for elite endurance athletes. 

Sodium has a profound impact on performance and physiological efficiency and function. Replenish is designed to support:  

1. Hydration During physical activity, athletes lose sodium through sweat. This loss needs to be replenished to prevent dehydration. Sodium helps the body retain water, maintaining optimal hydration status. 

2. Muscle Function: An adequate level of sodium helps prevent muscle cramps, especially during long-duration events. Sodium ensures proper muscle relaxation and contraction cycles for sustained muscle performance.  

3. Body Temperature Regulation: Sodium is a key component of sweat. Sweating is the body’s natural cooling mechanism, and adequate sodium levels help maintain effective sweating, preventing overheating. Consistent sodium intake helps athletes adapt to hot and humid environments, which is critical for endurance events held in such conditions.  

4. Cognitive Function & Mental Performance: Maintaining electrolytes, in particular sodium balance, is essential for proper brain function, especially during long-duration endurance events. Electrolytes support cognitive processes, which are crucial for mental clarity and coordination during endurance activities. 

5. Nutrient Transport: Sodium is involved in the active transport of nutrients such as glucose and amino acids into cells. This process is vital for energy production and muscle repair, supporting endurance performance and recovery. 


Many studies have shown that, on average, athletes lose 1000 mg of sodium per liter (32 oz) of sweat, with some athletes exhibiting even higher losses in lab tests. Therefore, athletes need to replenish their sodium levels during training and racing to maintain optimal body function. We formulated Replenish with 1000 mg of sodium per serving because, for most athletes, this is the minimum amount they need to replace per hour. 

How to Incorporate Replenish Into Your Training Routine 

Your intensity of your training and how much you sweat, will play a crucial role in figuring out how much Replenish you will need to intake for training. 

1. For higher intensity training and high sweat rate sessions: Drink 1-2 Servings of Replenish with 20-30oz of water during training. 

2. For lower intensity training and less of a sweat rate sessions: Drink 1 Serving of Replenish with 20-30oz of water during training. 

3. Rehydration AFTER training: Drink 1 Serving of Replenish with 20oz water.


During sleep, you go hours without water and your body naturally  loses fluids through breathing and perspiration, leading to  dehydration by morning.  

Replenishing electrolytes in the morning is important for physical  and cognitive performance during the day, while combating  fatigue and further dehydration. Replenish not only rehydrates but  also restores your electrolyte balance, setting the foundation for a  day of enhanced focus and energy.  

We developed our Chocolate Replenish powder to be a delicious  way to add electrolytes to your mourning routine. Add to your  coffee, smoothie, or mix directly in water or milk. 

The science behind electrolytes

Electrolytes are crucial in the body for several reasons, as electrolytes play a  key role in various physiological processes. Daily electrolyte balance is critical  for:  

1. Cellular Function: Electrolytes like sodium are vital for cellular activities,  including nerve function, muscle contraction and heart function. 

2. Fluid Balance: Electrolytes help regulate the distribution and movement  of fluids within the body, ensuring cells (and ultimately every part of the  body) are properly hydrated. 

3. Nerve and Muscle Function: Electrolytes are essential for the proper  functioning of nerves and muscles. 

4. Hydration:Proper electrolyte levels are necessary for effective hydration.  Electrolytes help retain water in the body, and their imbalance can lead to  dehydration or overhydration, both of which can be harmful. 

5. Enzyme Activity:Many biochemical reactions in the body, including the  production of energy, depend on enzymes, which require certain  electrolytes to help them function correctly.  

6. Cardiac Function: Electrolytes such as sodium influence blood volume  and pressure and overall heart function.  

7. Transport of Nutrients and Waste: Electrolytes assist in the transport of  nutrients into cells and the removal of waste products out of cells. This is  essential for maintaining cellular health.  


Hydration is so much more than water. In fact, overconsuming water  without electrolytes can be a detriment. Electrolytes such as sodium,  magnesium, and potassium, are essential to hydration in the body. 

Consuming excessive amounts of water without adequate mineral  replenishment can actually reduce your body's sodium levels. It's  essential to keep a balance between water and electrolyte intake. 

Endurance Replenish has a specific combination of electrolytes for  optimal hydration and taste.  

Sodium Citrate: An alkaline form of sodium that offers better  absorption, a less salty taste, and improved stomach comfort.

Sea Salt: A natural source of sodium, rich in trace minerals..

Chloride: Works with sodium to maintain fluid balance and blood  volume. 

Replenish allows you to replace your sodium needs while keeping your  gut and taste buds happy.
