Sodium is an electrolyte mineral involved in fluid balance, nerve signalling and muscle contraction. Most people get enough sodium from food, so supplement context matters.

Support

What Sodium does

Sodium is best understood through its main roles in normal body function. The exact relevance depends on diet, health context, dose and product suitability.

Fluid balance

Helps regulate fluid movement inside and outside cells.

Nerve signalling

Supports normal electrical signalling in nerves.

Muscle function

Works with other electrolytes in muscle contraction.

Sources

Where Sodium comes from

Food sources are usually the starting point. Supplements may be considered when intake, needs, testing or professional advice suggests extra support is appropriate.

Salt

Table salt and sea salt are major sodium sources.

Processed foods

Bread, sauces, packaged foods and snacks can be high in sodium.

Electrolyte products

Some hydration formulas include sodium for sweat-loss replacement.

Forms

Common forms and label language

Mineral products may use different forms. Check the exact form, amount per serve, directions, warnings and whether the mineral already appears in another formula.

Sodium chloride

Common salt form used in food and some electrolytes.

Sodium citrate

Used in some electrolyte and hydration products.

Sodium bicarbonate

Used in specific sports or alkalising contexts.

Electrolyte blends

Often paired with potassium and magnesium.

Safety

When to be careful

Minerals are essential, but more is not automatically better. Safety depends on dose, form, kidney function, medicines, age, pregnancy status and existing health conditions.

Blood pressure context

People with high blood pressure, kidney disease or heart disease should seek advice.

Not always needed

Most diets already contain enough sodium.

Sweat-loss context

Electrolytes may suit heavy sweating, heat or endurance activity, not casual daily overuse.
