Hydration isn’t just about drinking more water, it’s about replacing the electrolytes your body loses through sweat so your muscles fire properly, your energy stays stable, and your performance doesn’t crash mid-workout.

Two of the most talked-about electrolyte mixes today are LMNT elecrolyte and Skratch Labs, and although both aim to improve hydration, they approach the problem from two totally different angles. If you’re comparing LMNT vs Skratch Labs, the real question begins with the ingredients. What’s inside each formula determines everything: absorption speed, sodium balance, gut comfort, and how well each mix works for different types of training.

LMNT Ingredients and Nutrition Facts

LMNT uses a minimal, high-electrolyte formula built for athletes who sweat heavily, train in hot environments, or follow low-carb or fasted nutrition. Here are its ingredients in point-paragraph form:

• Sodium (1000 mg) – a very high amount of sodium designed to quickly replace sweat loss, prevent muscle cramping, maintain blood volume, and support fast rehydration during intense or hot-weather workouts, especially for heavy sweaters or endurance athletes who experience large sodium drops.
• Potassium (200 mg) – helps regulate nerve impulses, prevents muscle fatigue, supports electrolyte balance, and maintains proper hydration inside the cells during training sessions.
• Magnesium (60 mg) – reduces muscle tightness, supports relaxation and recovery, improves hydration efficiency, and helps the body use electrolytes more effectively under stress.
• Zero Sugar – contains absolutely no glucose, which makes it perfect for keto, fasting, low-carb athletes, and anyone avoiding insulin spikes; however, the lack of sugar means hydration absorption is slower than mixes with glucose.
• Zero Calories – delivers pure electrolytes without energy intake, ideal for fasted morning training, weight cutting phases, metabolic flexibility, or athletes who don’t want carbs during workouts.
• Simple Ingredient Base (salt, magnesium malate, potassium chloride, citric acid, natural flavors) – no fillers, artificial sweeteners, dyes, or unnecessary additives; a clean, functional formula focused only on replenishing essential minerals fast.

This combination gives LMNT an aggressive electrolyte profile made for athletes who need maximal sodium with no carbs. It is not designed for fueling — only hydration and mineral replacement.

Skratch Labs Ingredients and Nutrition Facts

Skratch Labs takes a balanced, endurance-centered approach using real fruit, natural sugars, and electrolytes designed for efficient absorption. Here are its ingredients written in your requested point-paragraph style:

• Sodium (380 mg) – a moderate level of sodium created for steady, endurance-friendly hydration that athletes can drink repeatedly without feeling overly salty or bloated during long training sessions.
• Potassium (39 mg) – helps regulate fluid balance, supports muscle function, prevents dehydration fatigue, and keeps electrolyte levels stable during multi-hour endurance sessions.
• Magnesium (21 mg) – supports hydration pathways, helps prevent muscle tightness or cramps late into long workouts, and improves overall electrolyte efficiency.
• Calcium (17 mg) – assists in muscle contraction, nerve signaling, and overall endurance performance, especially in long runs or long rides where repeated muscular activation is constant.
• Sugar (19 g from cane sugar + real fruit) – a small, strategic amount of glucose that speeds up fluid absorption using the sodium-glucose co-transport system, giving faster hydration and mild energy support without upsetting the stomach.
• Calories (~80 per serving) – functional fuel designed to help maintain energy, glycogen levels, and hydration efficiency for athletes training 60 minutes or more.
• Real Fruit Powder – provides natural flavor, better digestion, and clean taste without artificial sweeteners or dyes; supports long-term sipping comfort during extended endurance workouts.

Skratch is engineered for hydration + fuel, meaning it helps the body move water faster while providing light, steady energy for endurance athletes.

Comparing LMNT vs Skratch Labs: Calories and Energy Support

LMNT delivers 0 calories, which is ideal for fasted training, keto, cutting phases, or athletes who want electrolytes without any glucose or carb intake. It keeps hydration clean and simple without influencing energy levels or blood sugar.

Skratch delivers around 80 calories, which become beneficial during endurance activities where the body needs a small amount of carbohydrate to maintain performance, mental clarity, and hydration speed. These calories are functional, not filler, helping athletes sustain long-duration efforts.

If you need fuel, Skratch wins.
If you want pure electrolytes, LMNT wins.

LMNT vs Skratch Labs: Sugar Strategy

LMNT contains zero sugar, making it perfect for athletes avoiding carbs or following nutritional plans that require low insulin response. This keeps the drink extremely clean but removes the rapid hydration effect that glucose provides.

Skratch contains 19 grams of sugar, which is used intentionally to accelerate absorption and provide gentle energy during long rides or runs. This amount won’t cause a crash — it’s just enough for performance enhancement, not sweetness.

If you want faster hydration and a light energy lift, Skratch is better.
If you want sugar-free and carb-free electrolytes, LMNT is your mix.

Skratch Labs vs LMNT: Electrolyte Strength

LMNT has very high sodium (1000 mg), making it superior for heavy sweating, hot climates, CrossFit, HIIT, and strength work. It prevents electrolyte depletion quickly and keeps water in the body longer.

Skratch has balanced electrolytes (380 mg sodium plus small amounts of potassium, magnesium, and calcium), which is ideal for long, steady endurance training where athletes need consistency and gut comfort over power.

LMNT is for maximum replacement.
Skratch is for long-duration hydration.

Skratch VS LMNT: Vitamins and Minerals

LMNT focuses only on the big three electrolytes — sodium, potassium, magnesium — making it clean but minimal.

Skratch includes additional minerals like calcium, plus trace nutrients from real fruit powder, giving it a slightly broader nutritional profile. This supports muscle function during long efforts.

For added micronutrient support, Skratch wins.
For pure electrolytes, LMNT wins.

Which One Fits Different Training Styles?

If you’re doing long endurance training like running, cycling, triathlon, or multi-hour workouts, Skratch Labs performs better because it hydrates faster, fuels lightly, and stays gentle on the stomach for hours.

If you’re doing high-intensity training like CrossFit, weightlifting, HIIT, sauna work, or you sweat heavily, LMNT is stronger because it replaces huge sodium losses and prevents cramping more effectively.

If you’re training keto or fasted, choose LMNT.
If you’re training 60+ minutes or need steady energy, choose Skratch.
