10 Best Sodium Supplements in 2026

With 750mg of sodium and 150mg of potassium per capsule, these pills provide a combined electrolyte dose designed for high sodium diets, such as those used in managing POTS. The unflavored, allergen-free formula offers a clean and convenient alternative to mixing powders, requiring no preparation or cleanup. Their portable, flip-top bottle and small size make them easy to carry and swallow for consistent intake throughout the day.

The trade-off is that each pill delivers less pure sodium than a dedicated 1000mg chloride tablet, so you might need to take more capsules to hit the same total. That makes Vitassium ideal for someone whose protocol calls for a combined sodium-potassium boost in a gentle, portable form, rather than someone solely seeking the maximum sodium per pill for the lowest cost.

Each tablet contains 390mg of sodium, a specific amount for those tracking their intake. With 240 tablets per bottle, this supply lasts longer than many alternatives, reducing the frequency of reorders. The product is made in a facility with NSF and GMP certifications, which provides a documented standard for its manufacturing process.

This product is all about the basics. It’s also just a plain tablet in a bottle, so if you need rapid absorption during activity or prefer a portable, single-serving format, you’d look elsewhere. This is the workhorse pick, effective, no-nonsense, and focused purely on delivering sodium chloride without extra cost or complexity.

A chewable tablet that starts working in under a minute makes sodium replacement a practical mid-activity task, not a chore. This format suits athletes in motion, runners, cyclists, hikers, who need to replace sweat losses without stopping to mix a drink. The inclusion of potassium, calcium, and magnesium rounds out the electrolyte profile, which is a thoughtful step beyond a basic salt pill. It’s a tool built for the specific scenario of managing sodium depletion during long, sweaty efforts where convenience is non-negotiable.

Your total supply volume is the main consideration here. With 60 tablets, you’re carrying a compact amount ideal for a race or a week of training, not a month-long stockpile. For someone needing high daily sodium intake outside of athletic contexts, like managing a prescribed high-sodium diet, a bulk option with far more servings per container would be more practical. The FastChews excel at their designed purpose: quick, no-fuss sodium for the athlete already in motion.

Each SaltStick capsule delivers a clean, zero-sugar electrolyte dose of 215 mg sodium, making it suitable for athletes monitoring carbohydrate intake. Its formula includes Vitamin D and is buffered, which the brand states can help reduce cramping from dehydration without causing stomach discomfort. The suggested use is one capsule with water every 30-60 minutes during activity, fitting a regimented hydration schedule.

The sodium content per capsule is 215 mg, which is less than the 750 mg in a single Vitassium Extra Strength pill for high sweat losses. Each SaltStick capsule contains a total of up to 660 mg of electrolytes from four key minerals. The product’s feature is its sugar-free, vegetarian formula designed for convenient dosing during workouts.

A single bottle containing 365 tablets of 1000mg sodium chloride makes this a practical, long-term supply for anyone on a professionally directed high-sodium protocol. It’s a straightforward, gluten-free source of elemental sodium for maintaining electrolyte balance and supporting hydration, designed for the user who values bulk convenience over a blended electrolyte profile. This is for the person who knows their sodium target and wants to hit it consistently without frequent reordering.

Its main limitation is its simplicity. That makes it an excellent foundational supplement, but you’ll need to ensure your other electrolyte needs are met separately. The bottle size, while efficient, is also one of the larger ones in the guide, so it’s better suited for a medicine cabinet than a gym bag.

A 1000mg sodium hit per serving makes these capsules a serious option for anyone who sweats heavily and needs a substantial, no-fuss electrolyte top-up. The formula bundles in meaningful potassium and a magnesium form chosen for nerve support, which speaks to a design for hard training or sauna sessions where cramp prevention is a priority. It’s a clean, sugar-free option that suits keto or fasting protocols where you want hydration support without breaking your fast.

Taking three capsules per serving is a noticeable commitment compared to single-pill alternatives. The 70mg of magnesium serves a supportive role rather than a therapeutic dose for a deficiency. For users who prioritize a combined electrolyte profile from a third-party tested, US-made supplement, these capsules offer a concentrated formula.

A buffered formula combining sodium and potassium is the defining feature here, making Thermotabs a logical pick for anyone whose electrolyte loss comes with significant sweating in the heat. The specific aim at preventing heat-related fatigue and cramps speaks directly to outdoor workers or endurance athletes in hot conditions, where potassium depletion often accompanies sodium loss. It’s a straightforward, no-mixing supplement designed for systematic, all-day replenishment rather than a single massive dose.

The product’s recommended use involves taking one tablet with water up to ten times a day, a dosing schedule that requires more frequent attention than single-ingredient options. This regimen is designed for managing a combined sodium and potassium deficit during sustained activity in heat. It is a tool specifically formulated for that balanced electrolyte loss, rather than a general-purpose supplement.

The blister-packed, waterproof design means these capsules stay intact in a sweaty pocket or a downpour, which is the entire point for someone trying to manage electrolyte loss on a long run or ride. This product is built for the athlete who sweats heavily and needs a no-fuss, portable salt source that won’t turn to mush, especially when relying on event feed stations where mixing a drink isn’t practical. Its digestion-friendly, artificial-ingredient-free formula is a thoughtful touch for gut stress during hard efforts, and the WADA batch testing provides a layer of assurance for competitive athletes.

The modest 15-count pack feels more like a race-day supply than a training staple for a true heavy sweater. Compared to a bulk option with hundreds of servings, you’ll be opening a lot of these small boxes over a season. It’s a premium, purpose-built solution for specific, high-sweat scenarios, not a cost-effective daily driver.

A formula that includes sodium, chloride, potassium, magnesium, calcium, and vitamin D3 covers the full spectrum of key hydrating minerals in one capsule. This simplifies a protocol for someone focused on comprehensive mineral balance rather than just sodium loading. It’s a logical pick for the tinkerer who wants to support muscle function and energy from multiple angles without juggling several individual supplements, especially given its sugar-free and third-party tested design.

The unspecified sodium amount makes it harder to compare directly to a targeted option for a high-sodium diet protocol. For someone who needs precise, high-dose sodium replenishment above all else, a simpler salt tablet might be the more calculable choice. But if your goal is general electrolyte support with the added benefit of vitamin D for absorption, this consolidated formula removes the guesswork.

Each tablet provides exactly 500 mg of sodium chloride, equivalent to 197 mg of sodium, which is clearly stated for precise tracking. This allows someone managing their intake for a medical protocol to know exactly how much they are taking per dose. It is a straightforward option for those who need a measured, simple salt supplement and don’t mind taking two tablets to reach one gram.

You get a lower sodium amount per pill. If you’re following a high-sodium protocol for something like POTS, you’d need several of these to reach the equivalent of one Vitassium Extra Strength capsule. That makes it less convenient for on-the-go use compared to a higher-dose option. For straightforward, no-fuss electrolyte replenishment after heavy sweating, however, the small tablet size and pure formulation are a pragmatic, budget-conscious choice.
