Legion Hydrate Ingredients (1,300 milligrams per serving)
Sodium (575 milligrams per serving)
Sodium is a naturally occurring mineral found in rocks, soil, water, and foods like meat, dairy, and vegetables. People have used it for millennia—mostly in the form of sodium chloride or “table salt”—to preserve and season food, trade as currency, and as part of cultural rituals.
Sodium plays many important roles in the body, but one of its most crucial is regulating fluid balance. It pulls water into the spaces around cells and into your bloodstream, and it signals your body to retain more of the fluid you drink, helping you stay hydrated.[1][2][3]
It also works with potassium to produce electrical signals by shifting in and out of cells, allowing your body to contract muscles, send nerve signals, and maintain a steady heartbeat.
Research shows drinking water with sodium can prevent dehydration during intense and prolonged exercise and thereby . . .
- Support endurance, especially when exercising in the heat[4][5][6]
- Support post-exercise rehydration[7][8][9][10]
- Help regulate core temperature during intense or prolonged exercise[11][12]
The clinically effective dose of sodium for supporting hydration depends on how much you lose through sweat.
Hydrate provides 575 milligrams per serving—enough to replace the sodium lost in about 0.7 liters of sweat, which is typical for 30-to-90 minutes of exercise. It also matches the concentration used in research showing benefits without pushing sodium intake too high.[13]

Potassium (115 milligrams per serving)
Potassium is a naturally occurring mineral found in rocks, soil, water, and many foods, especially apricots, lentils, and potatoes.
While sodium regulates fluid outside cells, potassium pulls water into them. This keeps fluid balanced on both sides of the cell membrane, helping with hydration and cellular function.
Potassium also moves in and out of cells to create the electrical charge that your body uses to contract muscles, send nerve signals, and keep your heart beating.
Research shows that drinking water with potassium alongside sodium can prevent dehydration during intense and prolonged exercise and thereby reduce fatigue and support endurance, focus, coordination, and muscle function.[14][15][16][17][18][19][20][21][22]
The clinically effective dose of potassium for supporting hydration depends on how much you lose through sweat.
Hydrate provides 115 milligrams per serving to maintain the same 5-to-1 sodium-to-potassium ratio typically lost in sweat.[23]

Magnesium (35 milligrams per serving)
Magnesium is a naturally occurring mineral found in rocks, soil, water, and foods like nuts, seeds, leafy greens, and legumes.
It’s involved in over 600 enzymatic reactions in the body, including those supporting muscle function, nerve signaling, energy production, and protein synthesis.[24]
Despite its importance, research shows that up to 30% of people don't get enough magnesium from their diet. Active people are especially at risk of deficiency, since exercise increases both magnesium needs and losses, creating a gap that can undermine physical performance.[25][26][27][28]
Research shows that supplementing with magnesium can . . .
- Support energy metabolism and muscle function[29][30]
- Improve strength and power[31][32][33][34]
- Reduce exercise-induced muscle damage[35][36][37][38]
Hydrate provides 35 milligrams of magnesium per serving, which is enough to replace what you typically lose during intense and prolonged exercise (but not enough to meet the recommended daily intake, so eat your vegetables).

Chloride (575 milligrams per serving)
Chloride is a negatively charged ion, or anion, that combines with elements like sodium and potassium to form common salts, such as sodium chloride (table salt) and potassium chloride.
It’s naturally found in water, in minerals like halite (rock salt), and in foods like seaweed, celery, and tomatoes.
Chloride works with sodium to move water into and around your cells, which helps regulate fluid balance throughout your body and keeps you hydrated. It also helps your muscles contract and your nerves communicate by maintaining proper electrolyte and pH balance across cell membranes.
While some research shows that chloride itself may improve hydration, the primary reason it’s in Hydrate is because it’s bound to sodium (as sodium chloride) and potassium (as potassium chloride).[39]
The clinically effective dose of chloride for supporting hydration depends on how much you lose through sweat.
Hydrate provides 575 milligrams of chloride per serving, which is enough to stabilize the sodium and potassium so they can be absorbed by your body.[40]

Naturally Sweetened and Flavored
While artificial sweeteners may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health.[41][42][43][44][45][46]
That’s why we use the natural sweetener stevia. Research shows that this ingredient is not only safe but can also confer several health benefits, such as supporting weight management, antioxidant activity, digestive health, and more.[47][48][49][50]

No Artificial Food Dyes, Fillers, or Other Unnecessary Junk
As with artificial sweeteners, studies show that artificial food dyes and fillers can cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[51][52][53][54][55]
That’s why we use natural coloring and flavoring derived from fruits and other foods as well as naturally derived ingredients for improving texture, enhancing shelf life, and facilitating the manufacturing process.

Unlike a supplement like creatine or vitamin D, an electrolyte supplement isn't recommended for everyone.
In fact, according to the current weight of the scientific evidence, most people will notice little or no benefit from an electrolyte powder beyond "tasty water."
That said, there is one group of people who can benefit: those who do long (60+ minute), sweaty workouts, typically in hotter environments.
If you're one of those people, this supplement may be worth adding to your regimen. If you’re not, however, it's almost certainly not worth it, unless your only goal is to make water easier to drink.↑
That’s 904 pages of scientific research that shows Hydrate works the way we say it does.↑
