You Don't Need Sugar to Hydrate: Electrolyte Absorption Explained
Do you really need sugar to stay hydrated?
The short answer is NO; however, the topic is more complex than that. To fully understand why sugar is often associated with hydration, it helps to know how the body absorbs fluids and electrolytes.
Hydration 101: Fluid & Electrolyte Balance
Maintaining proper fluid balance is essential for healthy skin, consistent blood flow, smooth digestion, and overall well-being. Fluid balance largely relies on your intake of fluids and electrolytes.
For example, adequate sodium intake helps regulate brain function, blood volume, and other processes that distribute water throughout your body.*
Therefore, a healthy hydration goal goes beyond just drinking 8 glasses of water. It's about consuming and absorbing just the right amount of fluids and electrolytes to keep your body functioning smoothly.
Now, let's discuss whether sugar plays any role in achieving this balance.
Does sugar help with hydration?
In the 1960s, Dr. Robert Crane, known as the father of glucose-based rehydration, concluded that glucose helps transport water and sodium through the gut and into the bloodstream.
Crane's "cotransport hypothesis" was later proven by the discovery of a protein in the small intestine called sodium-glucose cotransporter 1 (SGLT-1). This protein operates as Crane theorized: when glucose is combined with fluids and salt, SGLT-1 enhances the absorption of all three components.
How the SGLT-1 cotransporter works
Glucose + sodium + water are absorbed together — which is why brands add glucose and call it "essential."
As a result, sports drinks and hydration brands include glucose as the key ingredient, "implying" that it's essential for hydration.
Can sugar dehydrate you?
Yes, other types of sugar, commonly found in sugary beverages, processed foods, and even dietary supplements can dehydrate you.
While glucose can aid hydration by enhancing water and sodium absorption, other sugars like sucrose (table sugar) and high fructose corn syrup don't offer the same benefits. Unlike glucose, fructose does not help absorb electrolytes and can actually disrupt the body's fluid balance. Research shows that excessive fructose consumption can increase urination and impair cellular water transport, leading to further dehydration.*
For most people, sugar isn't necessary for daily hydration. Although glucose can be beneficial in specific situations involving extreme dehydration—such as during intense exercise or illness—its marginal hydration benefits are often outweighed by the downsides of consuming extra sugar.
Unfortunately, many hydration and supplement brands load their products with sugar for “enhanced absorption” and flavor. Sure, taste matters, but it shouldn't come at the expense of your health.
Their sugar content might not appear concerning at first glance—typically 5-6 grams per serving—however, when you realize that some of these servings are only 8 grams in total, you'll be surprised that these so-called "healthy products" are made up of 70-80% sugar!🤮
What's actually in a typical sports drink
~5–6 g of sugar in an ~8 g serving. Root'd, by comparison, has 0 g.
Root'd MULTI VS Traditional Vitamins and Hydration Drinks
At Root'd, we put your wellness first by crafting supplements that are both effective and enjoyable. We use natural sweeteners like monk fruit, which provides a touch of sweetness without the sugar crash and offers additional health benefits you can feel good about.
While most hydration and sports drinks use sugars to boost vitamin + electrolyte absorption, our formula uses an innovative blend of enzymes + probiotics to promote absorption.* This gives you added hydration and ZERO sugars.
Root'd is an extremely potent vitamin drink, designed to nourish and give you everything you use when you move and replenish what you lose.*
Root'd vs. a traditional sports drink
🥤 Root'd MULTI
- Sweetened with monk fruit
- Enzymes + probiotics for absorption*
