Sodium
Last updated: August 9, 2026
Benefits
An electrolyte that maintains fluid balance and supports nerve and muscle function. Most people get plenty, so the goal is a ceiling to stay under, not a target to reach.
How much you need
Sodium works differently from most nutrients here: the table below is a ceiling to stay under, not a target to reach. There's no added benefit to getting more of it once you're at this level — these are recommended daily maximums, drawn from the same NASEM tables as every other nutrient on this site.
| Life stage | Recommended daily limit |
|---|---|
| Children 1–3 | 1200 mg |
| Children 4–8 | 1500 mg |
| Boys 9–13 | 1800 mg |
| Girls 9–13 | 1800 mg |
| Males 14–18 | 2300 mg |
| Females 14–18 | 2300 mg |
| Men 19–50 | 2300 mg |
| Women 19–50 | 2300 mg |
| Men 51–70 | 2300 mg |
| Women 51–70 | 2300 mg |
| Men 71+ | 2300 mg |
| Women 71+ | 2300 mg |
| Pregnancy 14–18 | 2300 mg |
| Pregnancy 19–50 | 2300 mg |
| Lactation 14–18 | 2300 mg |
| Lactation 19–50 | 2300 mg |
Upper limit
For Sodium, this is the same number as the recommended daily limit above — there's no separate, higher "safe max" above the target, because the target itself is already a ceiling.
| Life stage | Tolerable upper limit |
|---|---|
| Children 1–3 | 1200 mg |
| Children 4–8 | 1500 mg |
| Boys 9–13 | 1800 mg |
| Girls 9–13 | 1800 mg |
| Males 14–18 | 2300 mg |
| Females 14–18 | 2300 mg |
| Men 19–50 | 2300 mg |
| Women 19–50 | 2300 mg |
| Men 51–70 | 2300 mg |
| Women 51–70 | 2300 mg |
| Men 71+ | 2300 mg |
| Women 71+ | 2300 mg |
| Pregnancy 14–18 | 2300 mg |
| Pregnancy 19–50 | 2300 mg |
| Lactation 14–18 | 2300 mg |
| Lactation 19–50 | 2300 mg |
Regularly exceeding this amount of sodium is linked to raised blood pressure, which strains the heart and blood vessels.

Frequently asked questions
How much Sodium should adult women stay under per day?
Adult women (19–50) should stay under 2300 mg of Sodium per day, per NIH/NASEM Dietary Reference Intakes.
How much Sodium should adult men stay under per day?
Adult men (19–50) should stay under 2300 mg of Sodium per day, per NIH/NASEM Dietary Reference Intakes.
Does pregnancy change how much Sodium you need?
No — the recommended amount stays at 2300 mg per day during pregnancy (ages 19–50).
Is there an upper limit for Sodium?
Yes — for adults 19–50, the tolerable upper limit is 2300 mg. Regularly exceeding this amount of sodium is linked to raised blood pressure, which strains the heart and blood vessels.

Good sources include Table salt, Naturally present in most whole foods, Broths and soups, Cheese, and Bread.
How Tavita handles this
Tavita logs Sodium from both the food you eat and the supplements you take, adding both into one running daily total. Because Sodium is a ceiling to stay under rather than a target to reach, the app shows it that way too — as an amount to watch, not a percentage of a goal to fill.
