Key Takeaways
GLP-1s reduce food and fluid intake, which may make hydration harder to maintain.
Dehydration on GLP-1s can be subtle at first, so it helps to watch for changes in thirst, urine color, energy, and how often you're drinking.
Water should come first, but electrolytes can be helpful when intake is low, sweating increases, or digestion changes.
AG1 Pro can fit into a daily GLP-1 routine when you add it to your morning glass of water.*
Taking a GLP-1 can help you feel full sooner and stay satisfied longer, which reduces overall calorie intake.1 But when you feel full sooner, it's also easy to drink less when you're eating less.
Your body still needs fluid for normal body temperature regulation, digestion, circulation, and kidney function—even when your appetite and thirst feel quieter than usual.
Hydration can also become harder if GLP-1-related digestive changes affect your routine, which is why health experts generally recommend paying closer attention to hydration, daily nutrition, and how your digestive system is responding while taking a GLP-1.1,2
There is no single water intake amount that fits everyone. Body size, activity level, climate, sweat loss, diet, and health status all affect fluid needs.
As a general reference, the National Academies set adequate water intake at about 125 ounces (3.7 liters) per day for men and 91 ounces (2.7 liters) per day for women, which includes water from beverages and food.3 That equals 11 glasses of water for women and 15 glasses of water for men every day. However, that doesn't mean everyone needs to drink that exact amount from a water bottle alone. Soups, smoothies, fruits, vegetables, and other beverages can all help contribute.
On a GLP-1, the more useful goal is consistency. If your thirst is lower than usual, try intentionally spreading fluids across the day instead of waiting until you feel thirsty.
Electrolytes are minerals like sodium, potassium, and magnesium that help support fluid balance, nerve signaling, and muscle function.3
So, should you drink electrolytes on a GLP-1? Perhaps, but it depends—electrolytes may be useful when you are drinking less than usual, sweating more, eating smaller meals, or dealing with digestive changes. They can also help make water more appealing if plain water feels difficult to drink at times.
That said, additional electrolytes do not need to be an automatic part of your routine every day. Some electrolyte products contain high amounts of sodium, which can add up in excess if you are already getting enough through food.
For most people, it's better to start with water and nutrient-dense meals, then use electrolytes when hydration is harder to maintain because of lower intake, sweating, heat, travel, or digestive changes.
Adequate GLP-1 hydration works better when you include it in routines you already have.

One final tip: If you are trying to rehydrate after a low-intake day, go slowly. Small, steady sips are usually easier than drinking a large amount all at once.
AG1 Pro is mixed with 10 to 12 ounces of cold water, making it easy to incorporate into your daily routine. While the water you drink contributes to your daily fluid intake, AG1 Pro is formulated to provide foundational nutrition.*
AG1 Pro is built on AG1 Next Gen and includes 80+ ingredients, including vitamins, minerals, prebiotics, probiotics, phytonutrients, creatine monohydrate, Ca-HMB, and zinc carnosine. It is formulated to complement reduced intake and help fill nutrient gaps that may occur with GLP-1 use, while also supporting muscle preservation and gut barrier health.*
Start your day with AG1 Pro as part of a routine that keeps daily nutrient support and consistent nourishment easier to maintain.*
