Everything you need to know, distilled into one definitive resource.
If you're starting a carnivore diet or keto diet and feel terrible in week one, you are not failing. You are running on depleted electrolytes. The single most preventable failure point of the first two weeks is salt, magnesium, and potassium loss - and it has a clean, mechanical fix.
Why Electrolytes Are Non-Negotiable on Carnivore and Keto
When carbohydrate intake drops, your insulin level drops with it. Insulin is one of the hormones that tells your kidneys to retain sodium. When insulin falls, sodium gets excreted. Water follows sodium out. Potassium and magnesium follow the water. Within 48-72 hours, you can lose enough of all three minerals to feel like you have the flu.
This is not the diet failing you. It is a preventable mineral deficiency that responds to electrolyte replacement within hours.
The fix is not more carbs. The fix is electrolytes.
Carnivore & Keto Electrolyte Daily Targets
These daily targets prevent and resolve adaptation symptoms. They are higher than standard government guidelines - and intentionally so, because the standard guidelines assume a high-carb diet where sodium retention is maintained by elevated insulin.
Mineral
Daily Target
Best Food Sources
Supplement Notes
Sodium
5,000-7,000 mg (2-3 tsp salt)
Unrefined sea salt, bacon, bone broth, cured meats
Salt food liberally - no supplement needed
Potassium
3,500-4,500 mg
Beef (350 mg/100g), salmon, bone broth, avocado
Food first. High-dose K capsules can cause heart issues
Magnesium
300-400 mg elemental
Mackerel, leafy greens, dark chocolate (keto)
Magnesium glycinate at bedtime is the gold standard
Chloride
Paired with sodium
Unrefined salt naturally contains it
Adequate if salt intake is adequate
Calcium
800-1,200 mg
Hard cheese, sardines with bones, bone broth
Pair with vitamin D and K2 for absorption
The Salt Shot: A 60-Second Fix for Keto Flu Symptoms
The Salt Shot is the single most useful tool in the first two weeks of carnivore or keto. It works in under a minute. Keep a glass jar of pre-mixed Salt Shot in the fridge before you start.
How to make the Salt Shot
Measure ½ teaspoon of unrefined sea salt - Redmond Real Salt, Baja Gold, or Celtic sea salt.
Dissolve it in 4 ounces of warm (not hot) water. Warm water dissolves salt faster.
Stir until fully dissolved. No grit at the bottom.
Drink in a single swig. It tastes like seawater - that's correct.
When to take the Salt Shot
First thing in the morning during the first 14 days (replenishes overnight sodium loss)
30 minutes before any workout
At the first sign of a headache, lightheadedness, or fatigue
During hot weather or after sweat-heavy activity
When traveling by air (cabin air dehydrates rapidly)
Most people feel relief from acute symptoms within 30-60 seconds. If symptoms don't resolve within 10 minutes, take a second one. If they still don't resolve within 30 minutes, the cause may be magnesium rather than sodium.
The Salt-Under-the-Tongue Trick
This is the fastest sodium delivery method available short of an IV. When a craving hits - usually for sugar, even though you're not actually hungry - place a small pinch of unrefined salt directly under your tongue. The minerals absorb sublingually within 60 seconds, bypassing digestion entirely.
More than 90% of acute cravings in the first month of low-carb eating are mineral deficits in disguise. The brain reads sodium deficit as a generalized drive for flavored food, and the easiest flavored food in the modern environment is sugar. Replace the missing mineral and the craving dissolves.
Practical tip: Keep a small jar of unrefined salt in your bag or desk drawer. Effect typically appears within 5-10 minutes.
Sodium on Carnivore and Keto: How Much Salt Per Day
The short answer: 5-7 grams of sodium per day for most active adults on a low-carb or carnivore diet. That works out to roughly 2-3 teaspoons of unrefined salt across the day.
Why low-carb diets require more salt
On a standard high-carb diet, your average insulin level is elevated throughout the day. Insulin signals your kidneys to retain sodium. On a low-carb or carnivore diet, your insulin level drops to a healthy baseline. The kidney's sodium-retention signal weakens. Sodium is excreted more aggressively. This is why dietary recommendations designed for high-carb populations (like the standard 2.3g/day guideline) do not apply to low-carb eaters.
Research support for higher sodium on low-carb
The largest meta-analysis on sodium intake and cardiovascular outcomes, published in The Lancet (n=130,000 across 49 countries), found that moderate sodium intake of 3-5 grams per day was associated with the lowest cardiovascular event rate. Both very high (>7g) and very low (<3g) intake increased risk. This is the J-curve of sodium intake.
For low-carb populations specifically, Virta Health recommends 3,000-5,000 mg of sodium daily. Diet Doctor's guidance is 4-7 grams. The carnivore community's working range tracks slightly higher (5-7g) because higher protein intake mildly increases sodium turnover.
How to hit your sodium target
Salt every meal liberally. Don't shake - pour. A ribeye can handle a quarter teaspoon of flaky salt.
One Salt Shot in the morning during your first 14 days (about 1.2g sodium)
One cup of salted bone broth daily (~500-800 mg sodium when well-salted)
Cured meats and bacon (check labels for sugar-free, no-seed-oil cure)
Pickled vegetables if you tolerate them (olives, pickles, sauerkraut - keto-friendly, not carnivore)
Magnesium on Carnivore and Keto: The Silent Mineral
Magnesium is the second-most-common deficiency we see. The symptoms of magnesium deficit are often mistakenly attributed to other causes.
Why magnesium is critical
Magnesium participates in over 300 enzymatic reactions in the body - energy production, muscle contraction, nerve transmission, sleep regulation, blood sugar control, and the regulation of sodium transport across cell membranes. It is not stored in large quantities and is depleted rapidly by stress, caffeine, alcohol, and intense exercise.
Modern soils are also depleted of magnesium. Most modern adults are mildly magnesium-deficient before they ever start a low-carb diet. The diet itself doesn't usually cause the deficit - it exposes it.
Daily magnesium target
Aim for 300-400 mg of elemental magnesium per day. "Elemental" matters - different magnesium forms contain different percentages of actual magnesium by weight.
Best magnesium forms (and which to avoid)
Magnesium glycinate: The gold standard. Highly absorbable, gentle on the gut, sleep-supportive. Take 300-400 mg at bedtime.
Magnesium malate: Good for fatigue and energy. Take in the morning.
Magnesium citrate: Works fast but has a laxative effect. Useful for occasional constipation; not ideal for daily use.
Magnesium oxide: AVOID. Only 4% bioavailable. The cheapest form, and the one most multivitamins use.
Topical magnesium chloride spray: Useful adjunct for muscle cramps and restless legs. Spray directly on calves at bedtime.
Magnesium deficiency symptoms
Leg cramps at night, especially in the calves
Restless legs, twitching, or muscle fasciculations
Difficulty falling asleep or staying asleep
Anxiety, irritability, or a feeling of being "wound up"
Constipation
Headaches that don't respond to a Salt Shot
Heart palpitations (always check with a clinician - palpitations have many causes)
Potassium on Carnivore and Keto
Potassium is usually the easiest electrolyte to hit through food. Meat is naturally potassium-rich - 100g of beef contains roughly 350 mg, salmon contains around 380 mg, and a cup of well-made bone broth delivers about 500 mg.
Daily potassium target
Aim for 3,500-4,500 mg per day. Two well-fed carnivore meals (e.g., a ribeye and a salmon fillet) plus a cup of bone broth gets most adults to target without supplementation.
Best potassium sources
Beef: 350 mg per 100g
Salmon: 380 mg per 100g
Pork: 340 mg per 100g
Lamb: 310 mg per 100g
Bone broth: ~500 mg per cup when well-made
Avocado (keto only, not carnivore): 487 mg per medium fruit
Spinach (keto only): 558 mg per cooked cup
Homemade Electrolyte Drink Recipe (Sugar-Free)
Commercial electrolyte powders often contain maltodextrin, dextrose, sucralose, or other additives that work against the diet. A homemade electrolyte drink is cheap, clean, and customizable to your specific deficit.
The base recipe (1 liter)
1 liter (4 cups) cold filtered water
1 teaspoon unrefined sea salt (~2,300 mg sodium)
½ teaspoon potassium chloride ("No-Salt" brand, optional, ~1,800 mg potassium)
100 mg magnesium glycinate or magnesium chloride flakes (optional)
Juice of half a lemon or lime, for flavor (keto only, omit for strict carnivore)
Optional: a drop or two of liquid stevia or monk fruit
Variations
Sodium-only quick fix: Just the salt + water. The bare-minimum Salt Shot scaled up.
Bone broth electrolyte: Replace half the water with bone broth. Provides sodium, potassium, magnesium, glycine, and collagen in one cup.
Pre-workout: Add a small splash of pickle juice for extra sodium and vinegar, which some athletes find prevents cramping.
Drink one liter across the day during your first two weeks. Reduce to half a liter or skip on rest days once adapted.
Best Salts for Carnivore and Keto Diets
The quality of your salt matters as much as the quantity. Standard processed table salt has been stripped of trace minerals, bleached, and combined with anti-caking agents. Unrefined ancestral salts retain a full spectrum of trace minerals.

The naked salt rule
Choose salt that looks alive: grey, pink, amber, off-white - but never pure white. Pure white salt has been processed beyond what your biology requires. Real unrefined salt clumps slightly because it retains moisture and minerals. The free-flowing pure-white salt in standard shakers has been industrially processed and combined with sodium aluminosilicate or calcium silicate as anti-caking agents. Keep it out of your kitchen.
Added dextrose (sugar - sometimes added as a stabilizer for iodine)

The Daily Electrolyte Protocol
This is the timed protocol that maps onto a typical day for an active adult during the first 30 days of carnivore or keto.
Morning (within 30 minutes of waking)
Salt Shot: ½ tsp unrefined salt in 4 oz warm water
One cup of well-salted bone broth, optional
Pre-workout (30 minutes before exercise)
Salt Shot or 8 oz electrolyte water
Skip if exercise is light or under 30 minutes
During training (sessions over 60 minutes)
Sip electrolyte water containing sodium, potassium, and magnesium
Sweat losses can exceed 1,000 mg of sodium per hour during intense exercise
Throughout the day (every meal)
Salt food generously with unrefined salt
Trust your taste buds - "needs more salt" is your body talking
Drink water to thirst, not on a schedule
Bedtime
300-400 mg magnesium glycinate
Optional small pinch of salt if nighttime cramps are a pattern
Seasonal adjustments
Summer / hot climates: Push to the high end of sodium targets (7g). Sweat-driven loss accelerates fast.
Winter: Maintain baseline (5-6g). Bone broth becomes the seasonal carrier - warm, salted, and nourishing.
Air travel: Cabin air is desert-dry. Take a Salt Shot before boarding and again after landing. Bring a small jar of salt.
Frequently Asked Questions
How much sodium do I need on the carnivore diet?
5,000-7,000 mg per day (roughly 2-3 teaspoons of unrefined salt) for active adults during the first 30 days. This is significantly higher than standard government guidelines because low-insulin diets cause the kidneys to excrete more sodium. People with congestive heart failure, salt-sensitive hypertension, or kidney disease should consult a clinician first.
How much sodium do I need on keto?
Same range as carnivore: 5,000-7,000 mg daily for most active adults. Diet Doctor's recommendation is 4-7 g; Virta Health's is 3,000-5,000 mg. The exact number depends on activity level, climate, and individual sweat rate.
What are the best electrolytes for the carnivore diet?
Sodium from unrefined sea salt (Redmond Real Salt, Baja Gold, or Celtic), magnesium glycinate at 300-400 mg before bed, and potassium from food (beef, salmon, bone broth). Avoid electrolyte powders containing maltodextrin, dextrose, or artificial sweeteners.
How do I make a homemade electrolyte drink?
Mix 1 teaspoon unrefined sea salt and ½ teaspoon potassium chloride into 1 liter of water. Add 100 mg magnesium glycinate. Optionally add a squeeze of lemon (keto) or omit for strict carnivore. Drink across the day during the first two weeks of adaptation.
Why do I get leg cramps on keto?
Almost always magnesium deficiency, sometimes compounded by sodium loss. Take 300-400 mg of magnesium glycinate 30 minutes before bed. Magnesium glycinate is the most bioavailable form and is gentle on the gut. If cramps persist, add a topical magnesium chloride spray on the calves.
How long do I need to take extra electrolytes?
The intensive protocol (Salt Shot in the morning, daily magnesium, salted bone broth) is most important during the first 14-30 days. After that, salt your food liberally, take magnesium glycinate at bedtime if you have any deficiency symptoms, and reach for the Salt Shot only on hot days, before workouts, or during travel.
Can I drink too much salt water on keto?
In healthy adults with functioning kidneys, excess sodium is excreted in urine. Acute symptoms of too much salt (nausea, increased thirst, bloating) are mild and resolve quickly. Real risk exists for people with CHF, kidney disease, or salt-sensitive hypertension. Anyone in those categories should follow a clinician-directed sodium target.
What's the best salt for the keto diet?
Redmond Real Salt is our daily-cooking pick - sourced from an ancient sea bed in Utah, free from modern ocean pollutants, with 60+ trace minerals. Baja Gold has the highest trace mineral density. Celtic Sea Salt is rich in magnesium. Himalayan Pink is the affordable everyday option. All five are better than processed table salt.
The Bottom Line
If you take only one thing from this guide, take this: the first two weeks of carnivore or keto are not the diet failing you. They are a preventable mineral deficiency with a clean, mechanical fix.
Salt your food. Take a Salt Shot in the morning. Take magnesium at night. Eat your meat and your broth.
The rest is patience. Two weeks of consistent electrolyte protocol delivers most adults to the other side of adaptation. From there, the diet largely takes care of itself.
