The Best Electrolytes for Keto
Going keto makes your body flush sodium and water fast, and potassium and magnesium go with it. That mineral drop is the keto flu: the fatigue, headaches and cramps of the first weeks. The right electrolyte replaces it all, with zero sugar and zero net carbs.
The short answer
The best electrolyte for keto is zero carb, zero sugar, and complete. Athletic Insight Hydration replaces the sodium, potassium and magnesium that ketosis flushes out, without a single net carb to break your state.

Why electrolytes matter on keto
When you cut carbs, insulin falls. Low insulin tells your kidneys to release sodium, and water, potassium and magnesium follow it out. This is the well-known early keto water drop, and it carries your minerals out with it.
That loss is what people call the keto flu. The fatigue, headaches, brain fog and muscle cramps of the first week or two are almost always an electrolyte shortfall, not a sign keto is failing.
Food alone rarely keeps up, because cutting processed carbs also cuts a lot of hidden sodium. Replacing the full set is what makes the switch to fat for fuel smooth and keeps you steady.
What to look for
Zero net carbs & sugar
No maltodextrin, dextrose, or hidden carbs that spike blood sugar and knock you out of ketosis.
The depleted minerals
Sodium, potassium, and magnesium are the three keto flushes fastest. A complete formula covers all of them.
Energy through the switch
Magnesium and B vitamins support energy as your body adapts to burning fat instead of carbs.

What's in every serving
Five electrolytes in gentle citrate form, plus a B-vitamin complex. Everything ketosis flushes out, with zero net carbs to break your state.
Sodium
100mgSodium Citrate
The mineral you dump first when carbs drop. Replacing it is the single biggest fix for keto flu.
Potassium
200mgPotassium Citrate
Lost alongside sodium in the early keto water drop. Replacing it stops the cramps and twitches of adaptation.
Magnesium
20mgMagnesium Citrate
The mineral keto dieters most often fall short on. Citrate form absorbs far better than the cheap oxide most brands use.
Calcium
40mgCalcium Citrate
The fourth core electrolyte most formulas skip, supporting nerve signalling and muscle contraction.
B Vitamins
B1–B12Full B Complex
Support energy metabolism as your body switches from carbs to fat for fuel.
Citrate Forms
spaGentle Absorption
Every mineral uses the citrate form, which absorbs efficiently and sits easy on the stomach.
Built for keto
Stays in ketosis
Zero sugar, zero net carbs. Nothing to spike blood sugar or knock you out of ketosis.
5 electrolytes
Sodium, potassium, magnesium and calcium cover everything low-carb eating depletes, not just one or two.
Gentle citrate forms
Citrate minerals absorb efficiently and sit easy on the stomach, unlike harsh chloride or oxide forms.
Beats keto flu
Replaces the sodium, potassium and magnesium that drive adaptation fatigue, headaches and cramps.
How to use electrolytes on keto
Start in the morning
Mix one scoop into a large glass of water when you wake, to top up the minerals you lost overnight.
Add a second serving during adaptation
In the first few weeks of keto, a second serving in the afternoon smooths out the worst of the keto flu.
Drink to thirst and salt your food
Keep water and salt up alongside your electrolytes, since low carb flushes both faster than usual.
