If you're into fitness, health, or simply looking for an everyday electrolyte product, you've probably heard about LMNT and Redmond Re-Lyte. These are two of the most popular electrolyte products on the market—and for good reason. Both brands make their products without any of the nasties like sugar, gluten, fillers, or artificial ingredients.

But how do you choose between LMNT and Re-Lyte? While the two share many similarities, there are key differences that might sway your decision depending on your preferences and needs. Below, we’ll break down those differences to help you decide which one deserves a spot in your routine.

Salt Source – Where Do They Get That Salty Goodness?

One of the most significant differences between LMNT and Redmond Re-Lyte lies in the type of salt they use. And believe us, not all salts are created equal!

LMNT

LMNT uses a high-purity salt sourced from the US, produced through a process called Evaporated Salt Production, also known as Solution Mining. This process involves injecting fresh water into underground salt deposits, dissolving it into a brine, and then boiling and evaporating it into pristine salt crystals.

Why does this matter? LMNT opts for this method to avoid traditional mining contaminants and microplastics found in sea salt. The result? A smaller chance of impurities contaminating your electrolyte mix. Plus, their method supports a more environmentally conscious approach to salt mining.

Re-Lyte

Re-Lyte features Redmond Real Salt, an entirely natural salt mined from an ancient seabed in Utah, USA. This salt is untouched by modern pollutants and comes packed with a wide range of trace minerals. For those who value the idea of completely natural and unaltered ingredients, Re-Lyte’s Real Salt might appeal to you.

Verdict: If purity and process matter to you, LMNT holds the edge with its modern evaporation method. However, if you lean towards natural, trace-mineral-packed ingredients, Re-Lyte’s Real Salt might be your winner.

Magnesium Type – Which Form Does Each One Use?

Magnesium comes in several different forms, and the two brands have taken different approaches to which ones they include.

LMNT

LMNT includes magnesium malate, a single, widely used form of magnesium, and nothing else alongside it.

Re-Lyte

Re-Lyte combines magnesium malate and magnesium glycinate. Magnesium glycinate is another commonly used form, and it's a popular choice in evening formulas. Combining the two forms is a thoughtful touch that gives the formula a bit more variety.

Verdict: Both products contain magnesium. Re-Lyte uses a multi-form blend and LMNT sticks to one form, so this one comes down to which approach you prefer.

Calcium Content

When it comes to calcium, Re-Lyte and LMNT differ slightly.

• Re-Lyte: Includes calcium in its formula.
• LMNT: Omits calcium, focusing instead on sodium, potassium, and magnesium.

If calcium is something you’re specifically looking for in an electrolyte product, Re-Lyte has you covered.

Packaging – Tubs or Sachets?

Convenience matters, especially if you want electrolytes on the go or prefer to stock up for home use.

• LMNT: Comes exclusively in sachets, making it ideal for travel, gym bags, or portion control.
• Re-Lyte: Offers both tubs and sachets, giving you more flexibility. Go for sachets if you’re on the move, or stick with the tub for an eco-friendlier option that’s perfect for home use.

Verdict: Re-Lyte offers both formats, so it covers more situations; LMNT keeps it to sachets.

Cost – What’s the Best Bang for Your Buck?

If you’re using them daily, price is undoubtedly a factor.

• Re-Lyte: Generally works out cheaper per serving, particularly if you opt for the tubs over sachets.
• LMNT: While slightly pricier per serving, fans argue that the quality and taste justify the cost.

Verdict: Re-Lyte is the more budget-friendly option, especially if you’re a regular user.

Shared Ground – Why You Can’t Go Wrong with Either

While LMNT and Re-Lyte have some key differences, they also share a lot, making either an easy choice. Both products are:

• Sugar-Free: Zero sugar, and keto-friendly.
• Free of Gluten and Fillers: No unnecessary add-ons—just clean ingredients.
• Artificial Ingredient-Free: No artificial colours, flavours or sweeteners in either formula.

No matter which you choose, you can trust you’re buying a carefully made electrolyte product from a brand that takes its ingredients seriously.

Which Should You Choose?

Ultimately, it comes down to your preferences and priorities.

• Go for LMNT if you want ultra-pure salt that’s carefully mined to avoid contaminants, or if magnesium malate is the form you prefer.
• Opt for Redmond Re-Lyte if you want naturally-mined salt, a multi-source magnesium blend, or more flexibility with packaging and cost.

Whichever you choose, you’ll end up with a sugar-free electrolyte product that fits easily into your routine.
