Sodium citrate, explained.

Sodium citrate is a source of sodium and a useful formulation ingredient. Understanding its form helps you read the numbers without turning one ingredient choice into a miracle claim.

Sodium is only part of the ingredient

Trisodium citrate contains three sodium atoms per formula unit. The rest of its mass belongs to citrate and, for the dihydrate, water. Pure anhydrous trisodium citrate is approximately 26.7% sodium by weight; the dihydrate is approximately 23.5%. The same gram amount therefore delivers different sodium depending on the form. [1, 2]

Both examples use the proposed 2.5% trisodium-citrate inclusion. They assume pure ingredients. They are not a choice between two finished GEAR products or a lab-tested nutrition declaration.

Why consider citrate rather than chloride?

The proposed Natural update changes the sodium source from salt to trisodium citrate. This changes the formulation’s chemistry and gives us a different ingredient to assess in taste, dilution and tolerance testing. It does not establish that the finished mix will taste neutral or be easier on every gut.

Swapping equal weights does not automatically increase sodium: pure sodium chloride is around 39.3% sodium, more than either citrate form. The sodium amount depends on how much of each ingredient is used as well as its sodium fraction.

Concentration and intake are different

A sodium amount per powder portion does not tell you sodium per litre unless the mixing volume is known. It also does not tell you sodium per hour unless you know how much is consumed over that hour. Heat, sweat rate, sweat composition and other foods or drinks can change the context.

Sodium-dependent glucose transport is not a reason to match the drink’s sodium and glucose in a simple fixed molecular ratio. It does not, by itself, determine a person’s sweat replacement needs.

A buffer is not a dental guarantee

Citrate and citric acid can form a buffer system, but that does not tell us the finished drink’s pH, its total acidity or its effect on tooth enamel. Nor does it prove that the drink will settle an acidic stomach. Those are separate claims that need appropriate evidence.

What you will see before sale

The supplier’s ingredient form and sodium specification must be confirmed, followed by final nutrition and mixing instructions. Until then, the recipe explorer shows the calculated range rather than one unqualified sodium claim. The practical goal is clear information for your training plan.
