The general recommendation for adult women is less than 2,300 mg of sodium per day, which equals about 5.75 grams (roughly one teaspoon) of table salt. The American Heart Association suggests an even lower target of 1,500 mg of sodium for optimal heart health. Most American women far exceed both numbers, with average intake hovering around 3,300 mg daily.
The Daily Limit in Practical Terms
Sodium and salt aren’t the same thing. Table salt is about 40% sodium by weight, so you need to multiply sodium milligrams by 2.5 to get the equivalent in salt. That means the 2,300 mg sodium cap translates to about 6 grams of salt, and the stricter 1,500 mg target works out to roughly 3.75 grams. For perspective, a single teaspoon of table salt contains about 2,300 mg of sodium, so the standard recommendation essentially means keeping your total daily intake to one teaspoon or less from all sources combined.
Your body actually needs very little sodium to function properly. Less than 500 mg per day is enough to maintain nerve signaling, muscle contraction, and fluid balance. Getting too little sodium is extremely unlikely for anyone eating a typical diet, since the vast majority of sodium comes from processed and restaurant foods rather than from the salt shaker at home.
Why These Numbers Matter for Women
Reducing sodium to recommended levels has a measurable effect on blood pressure. In a clinical trial published in the Journal of the American Heart Association, people who lowered their sodium to guideline levels saw their systolic blood pressure (the top number) drop by about 9 mmHg compared to a control group. Diastolic pressure dropped by 4 to 5 mmHg. That magnitude of change is comparable to what some blood pressure medications achieve, which makes sodium reduction one of the most impactful dietary changes you can make for cardiovascular health.
For women specifically, high sodium carries an additional risk that often goes unrecognized: bone loss. Sodium and calcium share the same transport pathway in the kidneys, so when your body excretes excess sodium, it pulls calcium out with it. This creates a negative calcium balance that forces the body to pull calcium from bones to keep blood levels stable. The effect is especially pronounced after menopause, when lower estrogen levels reduce the kidneys’ ability to hold onto calcium. A postmenopausal woman on a high-sodium diet loses more calcium per unit of sodium than a premenopausal woman eating the same amount.
Salt and Your Menstrual Cycle
If you notice bloating, swollen ankles, or breast tenderness in the days before your period, sodium plays a role in how severe those symptoms get. During the luteal phase (the roughly two weeks between ovulation and your period), rising progesterone levels increase capillary permeability, allowing more fluid and protein to leak from blood vessels into surrounding tissue. At the same time, the hormones that regulate fluid retention, including aldosterone, spike significantly. Women with premenstrual syndrome show exaggerated increases in these fluid-regulating hormones compared to women without PMS.
The result is genuine salt and fluid retention during the second half of your cycle. While this is a normal hormonal process, eating more sodium during this window amplifies the effect. Keeping sodium intake steady throughout the month, rather than giving in to salty cravings, can reduce the severity of premenstrual bloating.
During Pregnancy
Pregnancy isn’t a reason to drastically restrict salt, but it’s also not a time to eat freely from high-sodium foods. The general guidance for pregnant women is 2,000 to 3,000 mg of sodium per day, which is close to the standard recommendation. Rigid salt restriction during pregnancy is not necessary and can actually be counterproductive, since your blood volume increases substantially and sodium helps maintain that expanded fluid balance. The practical advice: cook with reasonable amounts of salt but limit highly processed snack foods and packaged meals, which tend to deliver sodium in large, concentrated doses.
Where the Sodium Actually Comes From
About 70% of the sodium in the average American diet comes from packaged, processed, and restaurant foods. This is why someone who never adds salt at the table can still be well over the daily limit. Bread and rolls are one of the largest contributors, not because a single slice is particularly salty, but because most people eat several servings a day. Deli meats, pizza, canned soups, cheese, sandwiches, and condiments like soy sauce and salad dressing round out the list.
Reading nutrition labels is the most reliable way to track your intake. Look at the sodium line and the serving size. A frozen meal that appears to contain 600 mg might actually list that as one of two servings per container, putting the real total at 1,200 mg, more than half your daily budget in a single sitting. Foods labeled “reduced sodium” still contain significant amounts; the label only means they have 25% less than the original version.
The 1,500 mg vs. 2,300 mg Debate
The 2,300 mg ceiling comes from the Dietary Guidelines for Americans and represents the upper limit for healthy adults. The American Heart Association’s 1,500 mg target is more aggressive and aimed at ideal cardiovascular health. There is no reliable evidence that eating less than 1,500 mg per day poses a risk for most people, so erring on the lower side is generally safe.
The exception is people who lose large amounts of sodium through sweat: competitive athletes, outdoor workers in extreme heat, and similar cases. For these individuals, the 1,500 mg floor may not apply, and sodium needs should be adjusted based on activity level and sweat losses. For most women working desk jobs or doing moderate exercise, staying between 1,500 and 2,300 mg is the range to aim for.
