The drinks with the most sodium are vegetable juices, certain electrolyte and rehydration beverages, protein shakes, and softened tap water. A single 8-ounce glass of regular V8 vegetable juice contains 640 mg of sodium, which is nearly 28% of the 2,300 mg daily limit recommended by the FDA. Most sodas, teas, and coffees are surprisingly low in sodium, but the drinks that do contain significant amounts can add up fast if you’re not paying attention.
Vegetable and Tomato Juices
Vegetable juice is the biggest sodium offender in the beverage aisle. Regular V8 100% Vegetable Juice packs 640 mg of sodium into an 8-ounce serving. That’s more sodium than you’d get from a small bag of potato chips. Most store-brand tomato and vegetable juice blends fall in a similar range because salt is added during processing to enhance flavor and act as a preservative.
Low-sodium versions exist and make a real difference. V8’s low-sodium vegetable juice drops to 140 mg per 8-ounce glass, cutting roughly two-thirds of the sodium. If you drink vegetable juice regularly, switching to a low-sodium version is one of the simplest swaps you can make. Look for products labeled “low sodium,” which by FDA rules must contain 140 mg or less per serving.
Electrolyte and Rehydration Drinks
Sports drinks and rehydration solutions are designed to replace the sodium you lose through sweat, so they contain sodium on purpose. Standard sports drinks like Gatorade typically contain around 21 mmol of sodium per liter, which works out to roughly 160 to 200 mg per 12-ounce bottle depending on the brand. That’s moderate, but it adds up if you’re sipping bottles throughout the day without actually exercising.
Rehydration solutions like Pedialyte contain significantly more sodium, ranging from about 30 to 55 mmol per liter. The World Health Organization’s oral rehydration formula goes even higher at 75 mmol. These products are meant for illness or serious dehydration, not everyday hydration. Electrolyte tablets that you dissolve in water can also create solutions with substantial sodium, sometimes equivalent to 28 to 56 mmol per liter depending on the brand and dosage.
Protein and Meal Replacement Shakes
Pre-made protein shakes are a sodium source that catches many people off guard. An 11.5-ounce bottle of Premier Protein vanilla shake contains 250 mg of sodium, about 11% of the daily value. Other brands in this category tend to fall in a similar range, typically between 200 and 400 mg per bottle. If you’re drinking one or two of these daily as meal replacements, that’s a meaningful chunk of your sodium budget before you’ve eaten any solid food.
Softened Tap Water
If your home uses a water softener, your tap water may contain more sodium than you’d expect. Water softeners work by swapping minerals like calcium and magnesium for sodium, and the result can be significant. One study of households with softened well water found an average sodium concentration of 278 mg per liter, with some homes reaching over 400 mg per liter and a few exceeding 1,000 mg per liter. For comparison, municipal water that hasn’t been softened averaged about 110 mg per liter.
If you drink several glasses of softened water per day, you could be consuming a few hundred milligrams of sodium without realizing it. Some people install a reverse osmosis filter at their kitchen tap specifically to remove the sodium their softener adds.
Milk and Plant-Based Milks
Cow’s milk naturally contains about 46 mg of sodium per 100 mL, which works out to roughly 110 mg in an 8-ounce glass. That’s not dramatic, but it’s not zero either, and it’s easy to forget when you’re pouring milk on cereal or adding it to coffee multiple times a day.
Plant-based milks fall in a similar range. Almond milk averages around 40 mg per 100 mL, while soy milk tends to run slightly higher with a median of 60 mg per 100 mL, though some brands reach close to 100 mg per 100 mL. An Australian audit of plant milks found no statistically significant difference in sodium levels between plant-based and cow’s milk overall.
Effervescent Tablets You Dissolve in Water
This one surprises most people. Fizzy vitamin tablets and effervescent pain relievers use sodium bicarbonate to create their bubbles, and that adds a substantial amount of sodium to your drink. A study measuring effervescent vitamin supplements found they averaged about 284 mg of sodium per tablet, with vitamin C products averaging even higher at 378 mg per tablet. The highest single tablet measured contained 565 mg of sodium, nearly a quarter of your daily limit.
Effervescent pain medications are similar. Products like Alka-Seltzer contain around 445 mg of sodium per tablet, and some aspirin formulations designed for migraines or colds reach over 500 mg. If you’re dissolving two tablets as a dose, you could be drinking over 900 mg of sodium in a single glass. The sodium content is typically listed on the packaging, but many people never think to check.
Sodas and Soft Drinks
Regular sodas are actually very low in sodium. A 12-ounce can of cola contains just 11 mg, and pepper-style drinks like Dr Pepper are about the same. Diet versions tend to be slightly higher but still minimal: diet cola has around 29 mg per can, and fruit-flavored sodas come in at about 34 mg. Ginger ale sits at roughly 26 mg per 12-ounce serving. None of these amounts are worth worrying about from a sodium perspective.
Iced Teas and Bottled Teas
Bottled teas are among the lowest-sodium packaged beverages available. Most brands contain between 0 and 30 mg per bottle. Snapple Peach Tea has 10 mg per 16-ounce bottle, Gold Peak Sweet Tea has 10 mg per 18.5-ounce bottle, and some brands like Liquid Death iced tea and Just Ice Tea register at 0 mg. Even the higher end of bottled tea, like Uncle Matt’s Organic Sweet Black Tea at 30 mg per 8-ounce serving, is still well under any threshold worth tracking.
How to Read Sodium on Labels
The FDA sets the daily value for sodium at 2,300 mg. Percentages on nutrition labels are based on that number, so a drink showing 11% means it contains about 250 mg. Products labeled “low sodium” must have 140 mg or less per serving, and “very low sodium” means 35 mg or less per serving. These label rules apply to all packaged foods and drinks sold in the U.S.
The biggest sodium traps in the beverage world are regular vegetable juice, rehydration solutions used casually, protein shakes consumed daily, and effervescent tablets. Sodas, teas, and plain water (unless softened) contribute very little. If you’re watching your sodium intake, checking the label on anything that tastes salty, savory, or fizzy from a tablet is the best place to start.
