LMNT vs Dr. Berg: Which One Replaces What You Sweat Out?

If you are comparing LMNT vs Dr. Berg, I would not start with which one has more electrolytes on the label. I would start with a much more practical question:

What are you actually trying to replace?

For heavy sweaters, the answer is usually sodium. For someone doing fasted training, sugar and calories matter more. And if potassium is your priority, the comparison changes completely.

For this comparison, I’m using LMNT Drink Mix and Dr. Berg Sports Hydration Electrolytes, because the Dr. Berg sports formula is specifically positioned around exercise and contains 500 mg sodium and 1,000 mg potassium per serving. LMNT

Here is where the two products become genuinely different.

Sodium: Sodium Replacement Angle

This is the biggest difference between LMNT and Dr. Berg.

LMNT gives you 1,000 mg of sodium per stick. Dr. Berg Sports Hydration gives you 500 mg. LMNT

That means one LMNT serving delivers twice as much sodium as one Dr. Berg serving.

After a sweaty workout, that matters more than the impressive-looking total electrolyte count on the front of the package.

Imagine finishing a two-hour hike in hot weather with your shirt soaked through. Your immediate electrolyte problem is not necessarily that you need an enormous amount of potassium. You need to replace the minerals you actually lost in meaningful quantities.

LMNT gives you 1,000 mg sodium in one stick, so it is the more aggressive sodium-replacement option.

Dr. Berg gives you 500 mg, which can be useful, but you may need two servings to reach the sodium supplied by one LMNT stick.

That creates a simple practical distinction:

LMNT = more sodium per serving.

Dr. Berg = less sodium per serving, but considerably more potassium.

For someone who sweats heavily and primarily wants sodium replacement, I would choose LMNT.

Potassium: Heavy-Sweater Angle

This is where Dr. Berg flips the comparison.

Dr. Berg Sports Hydration provides 1,000 mg potassium per serving, compared with 200 mg in LMNT. Dr. Berg

That is a fivefold difference.

So if you are looking at the label and thinking, “Dr. Berg has way more electrolytes,” this is probably the number you’re noticing.

But there is an important practical distinction.

Heavy sweating does not automatically mean you should choose the product with the highest potassium number. Your sweat contains electrolytes in different proportions, and sodium is generally the mineral that becomes especially important to replace during substantial sweating.

That is why LMNT deliberately emphasizes sodium, with a 1,000 mg sodium and 200 mg potassium formula. LMNT Electrolytes

Dr. Berg takes the opposite approach: 500 mg sodium + 1,000 mg potassium. Dr. Berg

So the question is not simply “Which has more potassium?”

Dr. Berg clearly wins there.

The better question is:

Will that extra potassium solve the problem you actually have?

If your main concern is replacing sodium after heavy sweating, I would still lean toward LMNT.

If you specifically want a much larger potassium contribution, Dr. Berg becomes more interesting.

Sugar: Fasted-Training Angle

Neither product is designed around traditional sugary sports-drink carbohydrates.

LMNT contains zero sugar, while Dr. Berg Sports Hydration also lists 0 g total sugar and 0 g added sugar. LMNT

That makes both considerably easier to fit into a fasted-training routine than a conventional carbohydrate-heavy sports drink.

But there is a small difference worth noticing.

Dr. Berg’s sports formula lists 4 g total carbohydrate, despite having zero sugar, while the LMNT formula is marketed as zero sugar and its core electrolyte formula contains no meaningful sugar load. Dr. Berg

So if your definition of fasted training is simply “I don’t want sugar,” both work.

If your definition is “I want the lowest possible caloric/carbohydrate input while getting electrolytes,” LMNT has the cleaner positioning.

There is also an LMNT Raw Unflavored option that the company describes as containing zero calories. LMNT Help Center

For strict fasted training, that is the version I would look at first.

Taste: Aftertaste

Taste is not just the first sip.

The more useful test is what happens 30–60 seconds later.

LMNT has a deliberately salty flavor profile because you are drinking a very high-sodium formula. Its ingredients vary by flavor, but the formula uses salt, magnesium malate, potassium chloride and, in flavored versions, acids, natural flavors and stevia. LMNT Help Center

That means LMNT can leave you with a noticeable salty/mineral finish.

Dr. Berg also uses stevia, but its flavor profile is built around ingredients such as citric acid, fruit flavors and potassium citrate, alongside its Himalayan salt and magnesium citrate. Dr. Berg

The interesting part is the mineral balance.

With 1,000 mg potassium and 500 mg sodium, Dr. Berg’s taste profile is not trying to deliver the same aggressively salty experience as LMNT.

So if you dislike a strong salty finish, Dr. Berg may be easier to drink.

If you actually like the salty taste that comes with a high-sodium electrolyte mix, LMNT makes more sense.

Convenience: Mixing Speed

Both products are designed around the same basic routine:

open → pour → add water → shake/mix → drink.

LMNT recommends mixing one stick into roughly 16–32 ounces of water, while Dr. Berg recommends one stick in 16 ounces. LMNT Electrolytes

So there isn’t a dramatic preparation difference.

The more practical difference is concentration.

Put LMNT into only 16 ounces and you’re getting a very concentrated 1,000 mg sodium drink.

Put Dr. Berg into 16 ounces and you’re getting half that sodium but five times the potassium.

For someone carrying electrolyte packets during a trek, gym session or long day outside, both are convenient.

LMNT wins if you want a high-sodium dose in one packet.

Dr. Berg wins if you want a high-potassium formula without carrying multiple products.

Price: Cost Per Sodium Delivered

This is where looking only at the price of one box can be misleading.

The current listed price I found for LMNT is $45 for 30 sticks, or about $1.50 per serving. LMNT

Dr. Berg’s 30-stick Sports Hydration box is listed at $28.99, or roughly $0.97 per serving. Dr. Berg

At first glance, Dr. Berg looks much cheaper.

But your requested metric is more useful:

Cost per sodium delivered

LMNT

• $1.50 per serving
• 1,000 mg sodium
• About $1.50 per 1,000 mg sodium

Dr. Berg

• ~$0.97 per serving
• 500 mg sodium
• About $1.93 per 1,000 mg sodium

So Dr. Berg costs less per packet, but LMNT gives you more sodium for the money when sodium itself is the thing you’re buying.

That’s an important distinction.

Cheaper packet ≠ cheaper sodium.

If your goal is specifically sodium replacement, LMNT has the better economics based on these listed prices.

If your goal is potassium, the calculation changes dramatically because Dr. Berg delivers 1,000 mg potassium per serving. Dr. Berg

Drawback: Extra-Calorie Problem

This is where neither product behaves like a sugary sports drink.

Dr. Berg Sports Hydration lists 20 calories per serving, with zero sugar. Dr. Berg

LMNT’s flavored mixes are positioned as zero-sugar electrolytes, while the company notes that some LMNT products contain very few calories; its Raw Unflavored version contains zero calories. LMNT

So if you’re finishing a workout and thinking:

“I only want electrolytes. I don’t want another drink that adds meaningful calories.”

LMNT has the advantage, particularly Raw Unflavored.

Dr. Berg’s 20 calories aren’t huge in the context of a normal diet, but they become relevant if you’re deliberately keeping your intake extremely low during fasted training.

This is one of those situations where the difference looks tiny on paper but matters to a specific user.

LMNT vs Dr. Berg: The Practical Verdict

I wouldn’t call one universally better.

They are built around different priorities.

Choose LMNT if:

• Your main goal is sodium replacement.
• You sweat heavily.
• You want 1,000 mg sodium in one serving.
• You train fasted and want zero sugar.
• You prefer a stronger sodium-focused formula.
• You don’t want to drink two packets just to reach 1,000 mg sodium.

Choose Dr. Berg if:

• Potassium is your priority.
• You want 1,000 mg potassium per serving.
• You want a lower-cost packet.
• You prefer a less sodium-heavy electrolyte profile.
• You want substantial potassium alongside magnesium and sodium.

My pick by situation

Situation	Better choice
Heavy sweating + sodium replacement	LMNT
Maximum potassium per serving	Dr. Berg
Fasted training	LMNT
Zero sugar	Both
Lowest packet price	Dr. Berg
Cost per 1,000 mg sodium	LMNT
High sodium in one serving	LMNT
High potassium in one serving	Dr. Berg
Avoiding calories completely	LMNT Raw Unflavored

The biggest mistake in this comparison is saying “Dr. Berg has more electrolytes, so it must be better.”

It has dramatically more potassium.

LMNT has dramatically more sodium.

Those are two completely different selling points.

If I were choosing specifically for a long, sweaty workout where sodium replacement is the main job, I’d take LMNT. If I wanted an electrolyte powder primarily because I wanted a large potassium dose, I’d take Dr. Berg.

And that is the real difference: LMNT is the sodium-heavy tool; Dr. Berg is the potassium-heavy tool.
