Why the first low-carb week hits so hard
Cutting carbs drops your insulin, and your kidneys respond by releasing the water and sodium they were holding. That flush is why the scale moves so fast in the first week, and it is why the headache, fatigue, and fog usually arrive on day two or three.
Most people feel it for a few days to about a week. How rough it gets tracks closely with how much sodium you replace while your body adjusts.
Signs you are running low
- A dull headache that starts a day or two after you cut carbs
- Fatigue and heavy legs that sleep does not fix
- Brain fog and trouble holding focus at work
- Muscle cramps, often in the calves at night
- Dizziness or a head rush when you stand up
- Irritability and cravings that feel out of proportion
What actually shortens it
Sodium leads the list, because it is the electrolyte the carb cut pushes out fastest. Drinking more plain water without replacing salt can thin what is left and leave you feeling worse.
A pinch of salt in water helps and costs nothing, though it is hard to dose and gives you nothing else. A purpose-built mix lets you hit a real sodium target alongside potassium and magnesium, the two minerals low-carb eaters tend to run short on next. Sugar is the one thing to leave out, since it works against the diet you just started.

Where Saltivate fits
Saltivate front-loads the mineral keto burns through fastest: 800mg of sodium per serving, plus 240mg potassium and 60mg magnesium, with zero sugar and zero carbs, so it does not touch ketosis.
Raw Unflavored is plain, with no sweetener or flavoring added, and its roughly 2g of salt lightly seasons a glass of water. The flavored mixes use OnoSweet, a Reb M fermented from rice rather than pulled from the stevia leaf, so there is no bitter aftertaste.
- 800mg sodium per serving, the mineral a carb cut flushes first
- Zero sugar and zero carbs, so it will not stall ketosis
- 240mg potassium and 60mg magnesium round out what low-carb depletes
- Raw Unflavored is plain, and mixes into water, coffee, or broth

Easy to drink, Tastes like nothing!
I wasn't sure what to expect, so I was so pleased that not only was the unflavored very satisfying in it's taste, but the flavored samples really caught me by surprise. Every electrolyte flavor I tried in the past was pretty awful, flavor so intense...
I have been running for 15 years and stopped drinking sport drinks and replace it with a grape cranberry 100% juice mixed with water however I found that in the Texas heat i would feel slightly dizzy and light headed after I stopped running during...

Common questions
How long does keto flu last?
Most people feel it for a few days to about a week, starting a day or two after they cut carbs. It tends to ease as your body adjusts to running on fat and as you replace the sodium the switch flushes out. If it drags on well past a week, or the symptoms are severe, that is worth raising with your doctor.
Do electrolytes help with keto flu?
Keto flu symptoms track closely with the sodium, potassium, and magnesium you lose when insulin drops and your kidneys release water and salt. Replacing them is the part you can act on today. Saltivate gives you 800mg sodium, 240mg potassium, and 60mg magnesium per serving with zero sugar, so it fits inside the diet.
How much sodium do I need on keto?
Low-carb eaters lose more sodium than usual because the diet flushes water and salt. Saltivate provides 800mg per serving, far more than most drink mixes. Start with one serving and adjust to how you feel. If you watch your sodium for any health reason, talk to your doctor first.
Will electrolytes break ketosis?
No. Every serving is zero sugar and zero carbs. Raw Unflavored has no sweetener at all, and the flavored mixes use OnoSweet, a zero-calorie Reb M. Fasting as well? Our electrolytes for fasting guide covers how it fits a fasting window.
Can I just use table salt?
Salt in water does replace sodium, and plenty of people start there. It is hard to dose consistently, and it leaves out the potassium and magnesium that low-carb eating also depletes.
Get ahead of the flush
Replace the sodium the first low-carb week strips out: 800mg per serving, zero sugar, no aftertaste. Pay with an HSA or FSA card at checkout, no paperwork needed.
