For anyone managing POTS or other forms of dysautonomia, the daily ritual of salt intake can be exhausting. You’re told to increase sodium, but eating enough salty food to make a difference often means feeling bloated, nauseous, or just plain tired of pretzels. Vitassium’s Plus Strength capsules are designed to fill that gap, offering 500 mg of sodium and 100 mg of potassium per capsule in a form that’s easier to swallow than a handful of saltines. After weeks of incorporating them into a regular routine, here’s how they hold up in practice.
The first thing you notice is the capsule size. They’re not tiny, but they’re also not the horse-pill proportions some supplements go for. Most people will manage fine with a glass of water. The bottle itself is straightforward—plain white, with a clear label that lists the electrolyte content prominently. There’s no proprietary blend, no added sugars or artificial colors, which is refreshing for a medical-grade product. The capsules dissolve quickly, and they don’t leave an unpleasant aftertaste, which is more than can be said for some chewable electrolyte tablets.
In terms of actual use, timing matters. The label suggests taking them with meals, and that’s worth heeding. Taking a capsule on an empty stomach can cause a mild wave of nausea, especially if you’re sensitive to salt. But when taken with food, the effect is steady. Many users, including myself in testing, find that one capsule with breakfast and another with lunch helps maintain blood pressure and reduces the lightheadedness that often hits mid-afternoon. It’s not a dramatic, immediate fix—you won’t feel a sudden surge of energy—but over a week, the reduction in orthostatic symptoms is noticeable.
Vitassium is formulated specifically for POTS, and that’s evident in the sodium-to-potassium ratio. Most sports electrolyte tablets, like Nuun or Liquid I.V., focus on hydration for athletes and often contain significantly less sodium—typically 100–300 mg per serving. Vitassium’s 500 mg per capsule is a different ballgame. For someone with POTS who needs 5–10 grams of sodium per day, that means 10–20 capsules daily, which is a lot of pills. But for those who need a moderate boost—say, an extra 2–3 grams on top of a salty diet—two or three capsules a day are manageable.
One trade-off is the potassium content. At 100 mg per capsule, it’s low enough to be safe for most people, but it also means you’re not getting a significant potassium replacement. If you’re also on a potassium-sparing diuretic or have kidney issues, this is something to discuss with your doctor. And while the product is labeled “Plus Strength,” that’s relative to Vitassium’s original formula, which has 250 mg of sodium. It’s not a mega-dose; it’s just a higher-strength version of their standard pill.
Another limitation is the cost. A 200-count bottle runs around $30–35, which works out to about 15–17 cents per capsule. If you’re taking 6–8 capsules a day, that’s roughly $3–4 daily—not exorbitant, but it adds up over a month. Generic sodium chloride capsules from a pharmacy are cheaper, but they don’t include potassium, and they’re often harder to find in the right dosage. For many, the convenience and formulation justify the price, but it’s not the most budget-friendly option if you’re solely chasing sodium.
Who is this for? It’s a solid choice for anyone with a confirmed POTS diagnosis who struggles to meet sodium targets through diet alone. It’s also useful for people with orthostatic hypotension or those on medications like fludrocortisone that require higher salt intake. The capsules are vegan, gluten-free, and free of common allergens, which broadens their appeal. However, it’s not for athletes looking for a quick electrolyte replacement during a workout—there are better-tasting, faster-absorbing options with added carbohydrates. And it’s definitely not for people with hypertension, heart failure, or kidney disease, where high sodium intake can be dangerous.
In real-world use, Vitassium Plus Strength does what it claims: it provides a reliable, measured dose of sodium and potassium in a convenient format. It doesn’t cure POTS, and it won’t replace the need for hydration and physical countermeasures like compression garments. But as a tool to manage daily salt intake, it’s practical and well-designed. The lack of sweeteners or flavorings means it’s less palatable than a drink mix, but that’s a trade-off for precision and portability. If you’re tired of chasing salt with food and want a predictable way to hit your numbers, this is a reasonable option to consider—just be mindful of the dosing and talk to your healthcare provider first.
