Overview

Ultima Replenisher has built its reputation on a simple promise: zero sugar, zero calories, zero artificial anything. In an electrolyte market increasingly populated by products containing sucralose, acesulfame potassium, or synthetic dyes, Ultima stands out as one of the genuinely cleanest formulas available. The ingredient list uses plant-based colors, organic stevia, and real fruit flavors across more than ten varieties. For ingredient-conscious consumers who have spent time reading labels and rejecting what they find, Ultima feels like a product designed specifically for them.

The formula includes six electrolytes (sodium, potassium, magnesium, calcium, chloride, and phosphorus) plus trace minerals and support vitamins including zinc and vitamin C. On paper, that is a more comprehensive mineral profile than most competitors offer. The problem is the quantities. Ultima contains just 55mg of sodium per serving, a fraction of what the body loses during even moderate exercise. For context, LMNT delivers 1000mg, DripDrop provides 490mg, and even the budget-tier Propel manages 160mg. At 55mg, Ultima is barely above what you would get from a glass of milk.

This makes Ultima a daily hydration product, not an athletic or recovery one. It excels at making your water taste better while adding a light mineral boost, and it does this without any of the ingredients that health-conscious consumers spend time avoiding. But anyone buying Ultima expecting it to prevent exercise cramps, combat heat exhaustion, or support performance during a long training session will be disappointed. The formula is deliberately gentle, which is simultaneously its appeal and its limitation.

Features Deep-Dive

The Clean-Label Gold Standard

Ultima's ingredient list is unusually transparent and genuinely free of the additives that populate most electrolyte products. There is no sucralose, no acesulfame potassium, no maltodextrin, no artificial colors, and no "natural flavors" hiding undisclosed compounds. The sweetening comes from organic stevia leaf extract. The colors come from real sources: beet juice, turmeric, and annatto. Every ingredient is listed with its specific amount.

This matters more than it might seem. Many products in this category market themselves as "clean" while burying sucralose in the fine print or hiding behind vague "proprietary blend" labels that obscure actual ingredient quantities. Ultima does none of this. The transparency extends to allergen declarations: the product is vegan, gluten-free, keto-friendly, paleo-friendly, soy-free, dairy-free, and non-GMO verified. For someone navigating multiple dietary restrictions, Ultima is one of the few electrolyte products that clears every common hurdle without compromise.

The trade-off is flavor intensity. Without sugar or artificial sweeteners to create the bold sweetness consumers are accustomed to from sports drinks, Ultima tastes noticeably lighter and more tart than competitors. The stevia provides mild sweetness, but the dominant flavor profile is citric acid tartness with fruit undertones. Some people love this restraint. Others find it underwhelming.

Six Electrolytes Plus Trace Mineral Support

While most electrolyte products focus on sodium and potassium with token amounts of magnesium, Ultima provides a broader mineral panel. The six-electrolyte formula includes calcium (20mg), phosphorus (8mg), and chloride (78mg) alongside the standard sodium, potassium (250mg), and magnesium (100mg). The addition of trace minerals and support vitamins (zinc, manganese, vitamin C) extends the formula beyond basic hydration into general mineral supplementation.

The magnesium content is worth noting. At 100mg per serving, Ultima delivers more magnesium than most competitors, which is relevant for the many people who are chronically under-consuming this mineral. Magnesium supports muscle function, sleep quality, and nerve signaling, and getting a meaningful dose through your daily hydration is a practical strategy. The potassium content at 250mg is also respectable, though still below the ~400mg that products like Redmond Re-Lyte or Transparent Labs provide.

The weakness is sodium, and it is a significant one. At 55mg per serving, Ultima provides less sodium than almost every competitor in this comparison. This is an intentional choice targeting people who already consume adequate sodium through food and want mineral support without adding more. But for anyone who exercises, sweats, or follows a low-sodium diet, 55mg is physiologically insufficient for meaningful rehydration. It is roughly the sodium content of a single celery stalk.

Format Flexibility: Stick Packs and Bulk Canisters

Ultima offers two purchase formats that serve different use cases. The stick packs ($1.05 per serving for a 20-pack) provide grab-and-go convenience for travel, gym bags, and office use. The 90-serving canister brings the per-serving cost down to roughly $0.33, making it one of the most affordable clean-label electrolyte options in bulk.

The canister format is where Ultima's value proposition strengthens considerably. At $30 for 90 servings, someone drinking one serving daily pays about $10 per month for clean-label electrolyte supplementation. That undercuts premium stick-pack brands like LMNT ($1.83/serving) by a factor of five. The canister comes with a scoop, and the powder dissolves quickly in cold water without clumping, a practical advantage over products that require vigorous shaking.

The flavor variety is also notable. With more than ten flavors including Lemonade, Grape, Passionfruit, Cherry Pomegranate, and Pink Lemonade, Ultima offers enough variety to prevent flavor fatigue across months of daily use. Variety packs in stick-pack format let newcomers sample multiple flavors before committing to a canister. One caution: the plant-based colors in darker flavors like Grape and Cherry Pomegranate can stain clear or white water bottles over time, particularly if the bottles are not washed promptly after use.

Pricing Analysis

Ultima's pricing splits dramatically between formats. Stick packs at $20.99 for 20 servings ($1.05 per serving) are competitively priced against similar single-serve options but unremarkable. The real value lives in the 90-serving canister at roughly $30, which brings the per-serving cost to approximately $0.33, making Ultima one of the cheapest clean-label electrolyte products available on a per-serving basis.

For comparison, Propel beats Ultima on price at $0.35 per serving, but Propel contains sucralose, acesulfame potassium, and artificial colors. Among products with genuinely clean ingredient lists, Ultima's canister pricing is hard to beat. Redmond Re-Lyte in tub format runs about $0.77, Transparent Labs Hydrate costs $0.75, and LMNT has no bulk option at $1.83. The caveat is that Ultima delivers far less electrolyte content per serving than any of these competitors, so the per-milligram cost of actual minerals is less favorable than the headline price suggests.

The stick packs make sense for trial purposes and travel, but the canister is where Ultima becomes a genuine value proposition. Subscribe-and-save options through the brand's website and Amazon further reduce the cost by 10-15%, pushing the per-serving price below $0.30. For someone who wants clean daily hydration without premium pricing, the canister format is the clear play.

Who Is This For?

Ultima Replenisher works best for:

• Ingredient-label readers and clean-eating advocates who have sworn off artificial sweeteners, synthetic dyes, and vague proprietary blends, and want an electrolyte product that matches the standards they apply to their food
• Desk workers and light-activity daily hydrators who want their water to taste better and provide a gentle mineral boost without needing the high-sodium, performance-oriented formulas designed for serious athletes
• People managing multiple dietary restrictions such as keto, paleo, vegan, gluten-free, or soy-free, who struggle to find electrolyte products that clear all their restriction hurdles simultaneously
• Budget-conscious clean-label buyers who purchase the 90-serving canister for roughly $0.33 per serving and want to avoid paying the premium stick-pack prices that brands like LMNT charge for similar ingredient purity

Who Should NOT Use This

Ultima Replenisher might not be the right choice if:

• You exercise regularly and need meaningful sodium replacement because 55mg of sodium per serving is insufficient for any activity that produces noticeable sweat, and relying on Ultima as your primary electrolyte source during workouts could leave you under-hydrated despite feeling like you are supplementing
• You expect sports-drink-level sweetness or flavor boldness since Ultima's stevia-and-citric-acid flavor profile is deliberately subtle and tart, which many people accustomed to Gatorade, Liquid I.V., or even flavored water find underwhelming or sour
• You use clear or white water bottles and do not wash them immediately because the plant-based colors in darker flavors can leave visible staining that builds up over multiple uses, particularly in textured or frosted bottle interiors

Bottom Line

Ultima Replenisher is the electrolyte product for people who care more about what is not in their hydration than what is. The ingredient list is genuinely spotless, the flavor variety is extensive, and the bulk canister pricing makes it one of the most affordable clean-label options available. But 55mg of sodium means this is a daily wellness product, not a performance or recovery tool. If you want clean hydration for your desk, your commute, or your leisurely walk, Ultima delivers. If you want electrolytes that actually keep pace with your sweat rate, you need to look elsewhere.

FAQ

Can I use Ultima during exercise or sports?

You can, but you should not expect it to replace what you are losing. At 55mg of sodium per serving, Ultima provides roughly 5-10% of what a moderately active person loses per hour during exercise. For a casual 30-minute walk or a light yoga session, Ultima adds a pleasant flavor and a gentle mineral boost. For anything involving substantial sweating, running, cycling, HIIT, or outdoor activity in heat, you would need to drink 10+ servings to match the sodium delivery of a single LMNT packet. That is not practical. Use Ultima for daily hydration and switch to a higher-sodium product for actual workouts.

Why is the sodium content so much lower than other electrolyte products?

Ultima designed its formula for people who already consume adequate sodium through their diet and want broad mineral support without adding more sodium. The average American consumes 3,400mg of sodium per day through food, well above the recommended 2,300mg. Ultima's perspective is that most people do not need more sodium; they need the other minerals (potassium, magnesium, calcium) that are commonly under-consumed. This philosophy makes sense for sedentary or lightly active people eating standard diets. It does not hold up for athletes, keto dieters, fasters, or anyone in a high-sodium-loss scenario.

Is the 90-serving canister a better deal than stick packs?

Significantly. The canister brings the per-serving cost from $1.05 down to roughly $0.33, a 68% savings. The only reasons to choose stick packs are if you are sampling flavors for the first time, need single-serve portability for travel, or want the convenience of pre-measured portions. For home use or office use where you have a scoop and a water bottle, the canister is the obvious choice. One canister lasts three months at one serving per day, making it a low-commitment purchase despite the higher upfront cost. The powder stays fresh for at least a year when the lid is kept sealed.
