Most healthy adults should aim for less than 2,300 mg of sodium per day, and many heart‑health organizations encourage a stricter target of around 1,500 mg per day, especially if you have high blood pressure or heart disease.

How Many mg of Sodium per Day?

Quick Scoop

  • General upper limit for adults: < 2,300 mg sodium/day.
  • Ideal target for better heart and blood pressure health: ~1,500 mg/day for most adults, especially if you have hypertension, heart disease, diabetes, or kidney issues.
  • What your body actually needs : roughly 200–500 mg/day just to function, so most of us eat far more than necessary.
  • Average intake today: many people get around 3,300–3,400 mg/day or more , well above recommended limits.

Group Recommended sodium per day (mg) Notes
Healthy general adult population < 2,300 mg Common upper limit in guidelines and on food labels.
Best for heart & blood pressure health ~1,500 mg Often advised as an “optimal” goal to lower chronic disease risk.
People with high blood pressure, heart disease, kidney disease, diabetes (ask your doctor) ≤ 1,500 mg (commonly advised) Stricter limits can help control blood pressure and reduce complications.
World Health Organization adult guideline < 2,000 mg Global recommendation for adults to reduce cardiovascular risk.
Body’s minimum physiological need ~200–500 mg Enough for nerve function and fluid balance; typical diets far exceed this.
Average intake in many countries ~3,300–4,300 mg Roughly 1.5–2× guideline limits.

Why the Limit Matters (In Plain Language)

Too much sodium pulls extra water into your bloodstream, which raises the volume of blood your heart has to pump and increases pressure on your blood vessel walls. Over time, that higher pressure stresses the heart, damages vessels, and raises the risk of heart attacks, strokes, and kidney disease.

Many people think “I don’t salt my food much, so I’m fine,” but most sodium comes from processed foods like breads, sauces, soups, frozen meals, and restaurant food, not just the salt shaker.

How Much Sodium Is That in “Real Food”?

Here’s a rough feel for what daily totals can look like:

  • 1 teaspoon table salt ≈ 2,300 mg sodium.
  • A typical restaurant meal can easily be 1,500–2,500 mg or more in one sitting, depending on the dish and portion size.
  • Bread, breakfast cereals, deli meats, cheese, canned soups, soy sauce, bottled dressings, and snack foods are common “stealth” sources even when food does not taste very salty.

So if your goal is 1,500–2,300 mg/day, a single salty meal can take up most of your daily allowance.

Simple Ways to Stay in the Safe Range

You don’t need perfection, but steadily cutting back makes a real difference.

  1. Check labels.
    • Look for products where sodium is closer to 5% Daily Value (DV) per serving (low) rather than 20% DV or more (high).
  1. Cook more at home.
    • Use herbs, spices, garlic, lemon juice, and vinegar instead of relying on salt for flavor.
  1. Choose “low sodium” or “no salt added” versions.
    • Especially for soups, canned beans, canned vegetables, sauces, and broths.
  1. Rinse canned foods.
    • Draining and rinsing canned beans and vegetables can wash away some of the sodium.
  1. Watch portions of salty foods.
    • Deli meats, cheeses, chips, instant noodles, frozen dinners, and restaurant meals add up quickly.

Quick FAQ

Is less than 1,500 mg/day dangerous?
For most healthy people, there is no strong evidence that staying between about 1,000–1,500 mg/day is harmful, and major heart organizations use 1,500 mg/day as a beneficial goal. If you have specific medical conditions, follow your clinician’s guidance.

Do athletes need more sodium?
Heavy sweating (endurance sports, hot climates, certain jobs) can increase sodium needs, and some people may be advised to replace losses more aggressively, but this should be individualized with a sports or medical professional.

Bottom line: For most adults, “How many mg of sodium per day?” translates to aim for under 2,300 mg and, if you can, move toward 1,500 mg —mainly by cutting back on processed and restaurant foods.
