The Science Behind
SOS Rehydrate


Using the best in medical and sports science, SOS was engineered by a leading doctor, two former elite athletes, and a retired military medical officer with the purpose of combating dehydration to improve overall human performance.


Impact of

During a normal day we lose about two litres of water just through breathing, sweat, urine and bowel movements. When we exercise, we can lose up to two litres per hour.

While sweating, the two main electrolytes lost are: sodium (range 10-70 mEq/L) and chloride (range 5-60 mEq/L). 13 ...

Dehydration results in an increase in cardiovascular strain, with heart rate being shown to increase by 4 beats per minute for each percent loss in body weight. This corresponds with an increase in body temperature and the rate at which glycogen stored in the muscles is consumed.

When we first start to sense thirst, we are already close to 2% dehydrated. This can result in headaches, tiredness and fatigue which are further exacerbated without adequate rehydration and rebalancing of electrolytes. 6, 7, 8



Hydrating for

When fluid arrives at the first portion of the small bowel, the unique SOS formula activates our bodies' Sodium/Glucose co-transport system. As part of this process, one molecule of sodium is pulled from the small intestine into the blood vessels by a corresponding molecule of glucose. Consequently, due to osmotic forces in the body, water is absorbed as it always follows sodium.

The 'Sodium/Glucose co-transport system' was discovered by the medical community, and is used to combat mild to moderate dehydration, saving millions of lives all over the world. This method of delivery is called Oral Rehydration Therapy (ORT) and is fully endorsed by the World Health Organization (WHO) and UNICEF. 2 ...

SOS matches the global standard set by the WHO. 9 We have also been able to lower the osmolarity and stabilize the taste – a complex challenge that no other rehydration drink has currently managed.

SOS is as effective as an IV Drip at combating mild to moderate dehydration. 3, 4

Osmolarity is the balance between water and sodium in the body. The normal (isotonic) osmolarity is 290mmol/L. The lower the osmolarity, the faster the body can absorb water. High glucose concentrations can increase the osmolarity of drinks.

SOS’ osmolarity is 230mmol/L, which means we are a hypo-tonic drink. The most effective formula for water-absorption when compared to isotonic and hyper-tonic solutions. 11, 12

SOS’ osmolarity is 20% lower than the average hydration drink, 25% lower than the average coconut water, 50% lower than the average sports drink, and over 80% lower than the average soda. 2

SOS Sticks

In an independent osmolarity test, SOS attained far superior scores in both Osmolarity rating whilst retaining the lower sugar content.


Both the SOS Stick and SOS RTD achieve the lowest osmolarity ratings, and beat all competitors on lowest sugar content.

The right mix your body needs.


This is the main electrolyte of the body because it keeps a balance ...with water. Sodium enables muscle contraction and nerve impulse transmission, prevents “water intoxication” and hyponatremia (low sodium in the blood), and helps with blood pressure control. Sodium is the main electrolyte lost through sweat.


Is the main electrolyte that lives inside of the cells ... It is involved in the correct functioning of the kidneys and heart, digestive system as well as muscle and nerve conduction. With 20 mEq/L we can avoid the development of hypokalemia (low potassium), and prevent heart arrhythmias and muscle cramping.


Even though it is the fourth most abundant mineral in the body, ... magnesium is underestimated; up to 70% of the population is magnesium deficient. This element is needed for more than 300 biochemical reactions in the body such as, immune system support, muscle and nerve function, heart rhythm regulation, energy creation, and protein synthesis.


This essential trace element has many functions in the body ... In addition to aiding fluid absorption, Zinc has also been proven to bolster immune function, regulate neuron communication in the brain, benefit muscle repair and growth, regulate hormones, and promote healthy heart function. Zinc is required for over 300 biochemical reactions in the body and prevents numerous health complications associated with Zinc deficiency, including chronic fatigue, nerve dysfunction, and hair loss.


This electrolyte works as a buffer by controlling acidity in the body ... It helps to prevent cramping and fatigue due to lactic acid production. Once absorbed, citrate converts into three molecules of bicarbonate, which is the body’s natural acidity regulator.


Is the second electrolyte lost through sweat. This chemical is needed by ... the body for many metabolic processes. It also helps in the acid-base balance and nerve impulse transmission.


The main fuel of the body is glucose. Glucose, in the correct amount, ... is good for you. SOS contains the ideal amount and the right kind of sugars (sucrose and dextrose) to help enhance the water absorption process and provide a constant and healthy energy source.

Malic Acid

This compound plays a key role in increasing energy production, ... reducing muscle fatigue during exercise, and improving mental clarity. Though enhancing mitochondrial uptake and respiration, malic acid encourages oxygen consumption and thus energy production. Malic acid even enhances the body’s ability to produce ATP (energy) in low oxygen conditions.
