Nuun vs LMNT: The Best Electrolytes and Why

Recent advances in hydration science have revealed that proper hydration involves far more than simply drinking water. Our understanding has evolved to recognize the crucial role that mineral forms, ratios, and bioavailability play in maintaining optimal hydration status.

This comprehensive analysis explores how LYTES, LMNT, and Nuun stack up against one another and which deserves the top spot. 

ESSENTIAL ELECTROLYTES - WHAT ARE THEY?

At their core, electrolytes are minerals that carry an electrical charge when dissolved in water. These charged particles play essential roles throughout our body, from maintaining proper fluid balance to enabling nerve signals and muscle contractions. The primary electrolytes our body needs include sodium, potassium, magnesium, calcium, and chloride. Each serves specific functions:

Sodium: The primary electrolyte in our blood, sodium regulates fluid balance and blood pressure while enabling nerve impulse transmission. Our bodies lose significant amounts of sodium through sweat, making it crucial for athletes and active individuals.

Potassium: Working in concert with sodium, potassium helps maintain proper cell function and heart rhythm. It's essential for muscle contractions and helps prevent cramping.

Magnesium: This mineral supports over 300 enzymatic reactions in the body, including energy production and muscle relaxation. The form of magnesium used in supplements significantly impacts its absorption and effectiveness.

Chloride: Often overlooked, chloride works with sodium to maintain proper fluid balance and helps produce stomach acid for digestion.

NUUN VS LMNT VS LYTES

Let's examine how each product approaches electrolyte supplementation, understanding the reasoning behind their formulation choices:

NUUN: THE ACCESSIBLE OPTION

Zero Sugar Hydration Tablets

$0.75/serving

Key Features:

• Sodium: 200mg (as sodium bicarbonate + sea salt)
• Calcium: 30mg
• Potassium: 125mg
• Magnesium: 20mg (as magnesium oxide)
• Chloride: 75mg
• Sweetener: Tapioca syrup solids

Sport Powder

$1.50/serving

• Sodium: 300mg (as sodium citrate + sea salt)
• Calcium: 15mg (as calcium citrate)
• Potassium: 150mg (as potassium citrate)
• Magnesium: 25mg (as magnesium citrate)
• Chloride: 40mg 
• Sweetener: Stevia Leaf Extract

NUUN'S FORMULA: 

Nuun's formulation represents a moderate approach to electrolyte supplementation, suitable for daily use and light activity. Their use of effervescent tablets creates carbonic acid, which some research suggests might enhance mineral absorption. However, their choice of magnesium oxide, while cost-effective, typically shows lower bioavailability compared to other forms.

LMNT: BASIC HIGH-SODIUM APPROACH

$1.50/serving 

• Sodium: 1,000mg (sodium chloride) 
• Potassium: 200mg 
• Magnesium: 60mg (magnesium malate)
• Sweetener: Stevia leaf extract 

UNDERSTANDING LMNT'S FORMULA: 

LMNT's high sodium content reflects research showing that active individuals and those following ketogenic diets often require significantly more sodium than traditional guidelines suggest. 

LYTES: PREMIUM HYDRATION

$1.50/serving 

• Sodium: 1,000mg (pink Himalayan salt)
• Potassium: 310mg
• Magnesium: 105mg (magnesium glycinate) 
• Chloride: 1,860mg
• Sweetener: Organic monk fruit
• Notable: Zero carbs, zero sugar, premium mineral forms

THE SCIENCE BEHIND LYTES

LYTES' use of pink Himalayan salt represents a holistic approach to mineral supplementation. Beyond just sodium and chloride, this form provides 84 trace minerals that act as cofactors, potentially enhancing the absorption and utilization of the primary electrolytes.

Magnesium glycinate —this form bonds magnesium to glycine, an amino acid that facilitates better absorption across cell membranes and typically causes fewer digestive issues than other forms.

At a quick glance, LMNT and LYTES both have less ingredients when compared to Nuun. 

UNDERSTANDING WHY FORMS AND BIOAVAILABILITY MATTER

Modern research has revealed that effective hydration depends on three key factors: mineral form, electrolyte ratios, and ingredient purity. These elements determine how well our bodies can absorb and utilize electrolytes, ultimately affecting hydration effectiveness and cellular function.

MINERAL FORMS MATTER

The Foundation of Absorption The bioavailability of minerals—how effectively our bodies can absorb and use them—varies dramatically based on their form. This principle is exemplified in LYTES' formulation choices:

SODIUM: PINK HIMALAYAN SALT VS PROCESSED SALT 

While standard supplements often use basic table salt, LYTES utilizes pink Himalayan salt, providing 84 trace minerals that enhance electrolyte absorption and cellular function. These trace minerals serve as cofactors, improving the body's ability to transport and utilize the primary electrolytes effectively.

MAGNESIUM GLYCINATE VS BASIC FORMS

LYTES' use of magnesium glycinate represents a significant advancement over the magnesium oxide or citrate found in conventional supplements. This form bonds magnesium to glycine, an amino acid that facilitates superior absorption across cell membranes while minimizing digestive discomfort.

Making an Informed Choice

When selecting a hydration supplement, consider these factors in order of importance:

1. Activity Level and Sweat Rate: Higher intensity activities require more comprehensive electrolyte replacement.
2. Dietary Restrictions: Keto dieters typically need more sodium; those fasting should avoid sugars.
3. Digestive Sensitivity: Some mineral forms and sweeteners may cause digestive issues in sensitive individuals.
4. Price Sensitivity: Premium ingredients typically come with higher costs.

INVEST IN QUALITY WITH PREMIUM HYDRATION

At $1.50 per serving, LYTES matches the price of competitors like LMNT and Nuun's Sport Powder.

While the cost is similar, LYTES uses premium forms of minerals like magnesium glycinate and pink Himalayan salt, which are generally better absorbed by the body. This gives you better value in terms of actual electrolyte absorption, even at the same price point.

TL;DR

Here's our opinion: 

LYTES outperforms Nuun by providing significantly higher electrolyte content (1,000mg vs 200mg sodium) and using premium magnesium glycinate instead of poorly absorbed magnesium oxide, while matching Nuun Sport's price point at $1.50 per serving.

 Compared to LMNT, LYTES offers superior mineral forms through pink Himalayan salt's 84 trace minerals versus basic sodium chloride, and delivers 75% more magnesium (105mg vs 60mg) in a more bioavailable form.

While both LMNT and Nuun use stevia, which can cause digestive issues in some people, LYTES uses clean monk fruit sweetener that's gentler on the stomach.

Unlike Nuun's added sugars and LMNT's basic mineral forms, LYTES provides a zero-sugar formula with premium ingredients that enhance absorption and effectiveness, making it the most comprehensive option for both athletes and everyday users.
