Ultima Replenisher has been hydrating its customers since 1996; long before the inception of most other brands we’ve reviewed. The longevity of the brand inspired confidence in the product even before trying it. For a company to survive for 25+ years means they are doing something right and is a sign that they’ve invested more in creating a quality product than perfecting a viral social media campaign. 

We also appreciated that the company didn’t make exaggerated claims about the effect of their electrolytes, like “cures hangovers instantly.” Instead, the company presents themselves as an everyday water enhancer that can used whether you’re active or laying low. Our team of reviewers found that Ultima Replenisher created a balanced and thoughtful product that addresses everyday hydration needs, validating the brands marketing.

The two characteristics of this product that stood out to our reviewers were flavor and quantity of electrolytes. Ultima comes in a variety of flavors ranging from lemonade to passionfruit and they’re all truly great-tasting. For those readers specifically looking for a delicious, 0 sugar, 0 carb electrolyte, you’ve found what you’re looking for. On top of that, Ultima comes jam-packed with electrolytes including sodium, chloride, magnesium, chloride amongst others. This is truly the “ultimate replenish-er.” See what we did there?

The only detractor, which is fairly minor (and common), was mixability. Ultima Replenisher required a bit more effort than other brands to get the powder fully dissolved. Given the stellar marks that the product received in every other category, we had no problem overlooking the mixability and happily muscled through the extra shakes or stirs. 

For those readers who are fasting, lowering carb intake or just looking for a good-tasting sugar-free electrolyte, your search stops here. Ultima Replenisher, with it’s electrolyte-packed, refreshing formula, will certainly come in handy whether you’re sweating it out in a workout class or looking for a drink to pair with your workday lunch.

You can’t go wrong having a few sticks of Ultima Replenisher on hand. Here, one of our reviewers gets ready to mix up a packet of the lemonade flavor while taking a walk in Central Park, NYC.


Ultima Replenisher had a noticeable effect for team members who took it as an everyday supplement. With all the electrolytes it packs, the obvious use case was taking it after a workout. Our reviewers found it restored energy and shortened recovery times when taken post run, bike ride and workout class. Interestingly, reviewers who tried Ultima as an every day supplement (with less physically taxing activities) also reported back “noticeable” results including improved mental energy and concentration. We loved how this product had a positive impact for both groups of testers. 

One of our reviewers who fit into the lower physical activity group enjoyed drinking Ultima Replenisher with her lunch during the work week in place of her usual coffee. This is a great reminder of the importance of boosting hydration even when you didn’t recently exercise.

“[Ultima Replenisher] was perfect for me… I felt more of a physical and mental boost than I get from my usual coffee. I liked how the energy carried into the early evening hours without any crash… The taste was great and made my boring weekday lunches more exciting.”  

While Ultima Replenisher is great for everyday applications and light exercise, it may not deliver the same results for more intense exercise due to its lower sodium content. If you’re someone who sweats a lot or routinely has workouts that last over 60 minutes, you may opt for a different product like LMNT or Liquid IV, both of which have a higher salt content. 

With that caveat in mind, it’s important to note that Ultima also sells all of their flavors in tubs of powder in addition to single serving packets. This affords you the flexibility to adjust the dosing depending on activity and personal preference. Maybe three quarters of a serving is a better fit for first thing in the morning, or one and a half servings after a workout. With the tub, you can experiment to find the dose your body responds best to.

Ultima Replenisher is the perfect electrolyte to restore energy after a light workout. Here, one of our reviewers gets ready to mix up some Ultima post paddle boarding.


As mentioned earlier, Ultima Replenisher is one of the best tasting electrolytes and offers a variety of flavors including: raspberry, blue raspberry, lemonade, pink lemonade, orange, grape, watermelon, and cherry pomegranate. The brand also likes to experiment with other, less common flavors. At the time of the most recent article update we’re seeing Appletini, Peach Bellini and Pina Colada… We need to try out these flavors ASAP! 

Lemonade was an all-around crowd pleaser and was especially pleasant mixed with ice on hot days. Pink lemonade and raspberry were also delicious alone or even with a meal. One reviewer commented that kicking his diet soda habit was easier when a cold glass of pink lemonade was substituted for soda at lunch time.


The Ultima Replenisher ingredient list is impressive and reinforces our perception that it’s a high quality product. It contains all of the top electrolytes including sodium, magnesium, calcium and phosphorus. On top of that, you’ll also get a boost of vitamin C, zinc, potassium, chromium, copper and more! All ingredients were present in small but sufficient quantities- you’ll get the post workout boost you need without compromising flavor. To earn the perfect 10/10 for this review category, Ultima Replensher was free of artificial flavors, sweeteners or colors. 

Ultimate Replenisher is one of the best electrolytes on the market. With 0 carbs, 0 sugar and 0 calories, yet high scores for effectiveness and taste, this a product that deserves shelf space in every kitchen. Find out for yourself how Ultima Replenisher can improve your energy levels and output.
