## Abstract

Oral rehydration solutions (ORSs), methods of preparing ORSs and methods of delivering rehydration therapy are disclosed herein. In some embodiments, an ORS includes a non-starch viscosity enhancing polymer and a sodium salt. The ORS may include at least approximately 50 millimoles of dissolved sodium per liter. Other embodiments may be described and/or claimed.

## Claims

### Claim 1

An oral rehydration solution (ORS) for drinking by a human, comprising:
a non-starch viscosity enhancing sodium salt polymer; and
a second sodium salt different from the non-starch viscosity enhancing sodium salt polymer;
wherein the ORS comprises at least approximately 50 millimoles of dissolved sodium per liter.

### Claim 2

(canceled)

### Claim 3 (depends on 1)

The ORS of claim 1, wherein the ORS comprises sodium alginate.

### Claim 4

(canceled)

### Claim 5 (depends on 2)

The ORS of claim 2, wherein the ORS comprises between approximately 0.1 and approximately 0.25 wt %.

### Claim 6 (depends on 1)

The ORS of claim 1, wherein the ORS comprises less than approximately 90 millimoles of dissolved sodium per liter.

### Claim 7 (depends on 1)

The ORS of claim 1, further comprising a potassium salt.

### Claim 8 (depends on 7)

The ORS of claim 7, wherein the ORS comprises between approximately 15 and approximately 25 millimoles of dissolved potassium per liter.

### Claim 9 (depends on 1)

The ORS of claim 1, further comprising a citrate salt.

### Claim 10 (depends on 9)

The ORS of claim 9, wherein the ORS comprises between approximately 8 and approximately 12 millimoles of dissolved citrate salt per liter.

### Claim 11 (depends on 1)

The ORS of claim 1, wherein the ORS comprises between approximately 50 and approximately 80 millimoles of dissolved chloride per liter

### Claim 12 (depends on 1)

The ORS of claim 1, further comprising less than approximately 115 millimoles of dissolved glucose per liter.

### Claim 13

(canceled)

### Claim 14 (depends on 13)

The ORS of claim 13, further comprising citric acid.

### Claim 15 (depends on 13)

The ORS of claim 13, further comprising hydrochloric acid, ascorbic acid, lactic acid, or L-glutamine.

### Claim 16 (depends on 1)

The ORS of claim 1, wherein a pH of the ORS is between approximately 3.5 and approximately 5.5.

### Claim 17 (depends on 1)

The ORS of claim 1, further comprising citrus flavoring, and wherein the pH of the ORS is between approximately 3.5 and approximately 4.5.

### Claim 18 (depends on 1)

The ORS of claim 1, further comprising a non-sugar sweetener.

### Claim 19 (depends on 1)

The ORS of claim 1, wherein the ORS does not include sucrose or fructose.

### Claim 20 (depends on 1)

The ORS of claim 1, wherein the ORS comprises approximately 70-75 millimoles of dissolved sodium per liter, approximately 65 millimoles of dissolved chloride per liter, approximately 75 millimoles of dissolved glucose per liter, approximately 20 millimoles of dissolved potassium per liter, and approximately 10 millimoles of dissolved citrate per liter.

### Claim 21

A method of preparing an oral rehydration solution (ORS) for drinking by a human, comprising:
in a vessel, dissolving a sodium salt, a potassium salt, glucose, and a citrate salt in water;
after the dissolving, introducing a non-starch viscosity enhancing sodium salt polymer into the vessel while agitating contents of the vessel to dissolve the non-starch viscosity enhancing sodium salt polymer;
after the introducing, adding an acid to the contents of the vessel until a target pH is reached, the target pH between approximately 3.5 and approximately 6, and the contents of the vessel comprise at least approximately 50 millimoles of dissolved sodium per liter.

### Claim 22 (depends on 21)

The method of claim 21, wherein the non-starch viscosity enhancing sodium salt polymer is introduced into the vessel in granule or crystalline powder form.

### Claim 23 (depends on 21)

The method of claim 21, wherein the non-starch viscosity enhancing sodium salt polymer comprises sodium alginate and the acid comprises citric acid.

### Claim 24 (depends on 21)

The method of claim 21, further comprising adding between approximately 2 and approximately 10 grams of non-sugar sweetener to the contents of the vessel per liter of ORS.

### Claim 25 (depends on 21)

The method of claim 21, further comprising adding a citrus or vanilla flavoring to the contents of the vessel.

### Claim 26 (depends on 21)
