Keto Supplements: What You Need, What's a Myth, and What's a Waste of Money

Electrolytes are the #1 keto supplement because insulin drops on keto, causing your kidneys to excrete more sodium, potassium, and magnesium. This is what causes "keto flu." It's not a withdrawal. It's dehydration and mineral depletion.

Sodium: 3,000-5,000mg daily (add salt to food, drink bone broth, use electrolyte mixes). Most people on keto dramatically under-salt their food because they're used to being told salt is bad.

Potassium: 1,000-3,500mg from food and supplements. Avocados, leafy greens, and meat provide some. Supplement the rest.

Magnesium: 300-500mg daily (glycinate or citrate). Muscle cramps on keto are almost always magnesium deficiency.

Omega-3s are important because keto diets tend to be high in omega-6 fats (from nuts, seeds, some cooking oils). Balancing with 1,000-2,000mg EPA/DHA keeps inflammation in check.

Fiber drops significantly when you cut carbs. Most keto dieters get 10-15g daily when they need 25-35g. Psyllium husk (5g daily, zero net carbs) fills the gap without kicking you out of ketosis.

MCT oil (medium-chain triglycerides) is legitimately useful on keto, but it's not required. MCTs bypass normal fat digestion and go straight to your liver for ketone production. This can help maintain ketosis, provide quick energy, and improve mental clarity.

C8 (caprylic acid) is the most ketogenic MCT. Products labeled "C8 MCT oil" are more effective for ketone production than generic MCT blends. Start with 1 teaspoon and work up to 1-2 tablespoons. Too much too fast causes "disaster pants" (urgent, oily diarrhea). Not exaggerating. Start slow.

MCT oil adds 100-130 calories per tablespoon with zero satiety factor. If weight loss is your goal, don't add MCT oil to coffee thinking it's "free." Calories count even on keto. It's best used strategically: pre-workout for energy or when you need cognitive fuel during a fast.

Exogenous ketones (BHB salts or ketone esters) are the biggest hype in the keto supplement world. Taking ketones while eating carbs doesn't give you the benefits of ketosis. It just adds ketones to your blood alongside glucose. Your body will burn the glucose first and the ketones become expensive, bitter-tasting calories.

For people already in ketosis, exogenous ketones might slightly boost ketone levels. But you're already making ketones. You don't need to buy them.

Ketone esters used in research cost $30+ per serving and taste truly horrible. They're research tools, not practical supplements.

Raspberry ketones have nothing to do with ketosis. They're a compound that smells like raspberries. One rat study showed fat-cell effects at doses that would require a human to take insane amounts. Complete waste of money.

"Keto pills" that claim to "put you in ketosis" without changing your diet are scams. Full stop. Ketosis is a metabolic state from carb restriction. No pill creates it.
