What daily sodium limit do adults have?
Most public health guidance sets the recommended daily sodium limit for adults at 2,300 mg per day (about 1 teaspoon of salt) as an upper limit for the general population. This aligns with U.S. dietary guidance intended to reduce risk of high blood pressure and cardiovascular disease.
Are there lower sodium limits for people with high blood pressure or risk factors?
Yes. Many guidelines encourage people with hypertension and some at-risk groups (for example, older adults, people with diabetes, or those with chronic kidney disease) to aim for 1,500 mg per day if possible, because reducing sodium can lower blood pressure in these populations.
Is the limit the same for everyone?
No. The “best” target can differ based on health status. Healthy adults often use 2,300 mg/day as the maximum, while clinicians may recommend 1,500 mg/day targets for people who need tighter blood-pressure control.
How to interpret sodium limits on food labels
Dietary sodium limits are based on sodium (not salt). Nutrition labels list sodium in mg per serving, so the daily number depends on how much you eat. Processed and restaurant foods are often the main sources of sodium.
Why does sodium matter?
Higher sodium intake is linked to increased blood pressure, which raises risk for heart disease and stroke. Lowering sodium can reduce blood pressure, especially in people with hypertension.

No sources were provided with the question, so I can’t cite specific documents here. If you tell me which country or guideline set you mean (e.g., U.S. Dietary Guidelines, WHO, UK), I can match the exact adult daily sodium limit to that standard.
