Frequently asked questions

What does the Sodium intake calculator actually compute?

It takes Age (years) and derives Upper limit and Ideal limit from them. The calculation is live as you type, so the result updates on every change.

What information do I need to provide?

A single value: Age (years). Nothing else is required — no account, no file upload.

Can you show a worked example?

With Age (years) = 30, the calculator returns Upper limit = 2,300 mg and Ideal limit = 1,500 mg. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

When would I actually use this?

Planning meals against a target, checking whether a habit covers the recommended intake, and translating a label into what it means for the day.

What is the most common mistake?

Treating a daily target as a daily requirement. Reference intakes are population averages over time; a day above or below one means nothing on its own.

How accurate is it, and what are the limits?

Upper limit follows the FDA daily value (2,300 mg; lower for children under 14). The ideal limit of 1,500 mg reflects the American Heart Association target. Needs vary; general information, not medical advice.

What is the difference between the Sodium intake calculator and the Fiber intake calculator?

This one returns Upper limit and Ideal limit; the Fiber intake calculator returns Recommended fiber. That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

Daily sugar intake calculator is the closest one after this: Find your WHO free-sugar limit from your daily calorie intake.

What else is worth having open alongside it?

Water intake calculator and Protein intake calculator — they come up in the same task often enough to be worth a second tab.

Where do the figures come from, and how current are they?

Reference intakes come from public health bodies (EFSA in Europe, the NIH and USDA in the United States) and differ between them. They describe populations, not you, and are not medical advice.
