Electrolytes

Electrolyte loss is the #1 cause of the 'keto flu'. When insulin drops, your kidneys excrete sodium rapidly — and sodium loss pulls magnesium and potassium with it. Replenishing these daily is non-negotiable on keto.

Electrolytes products

LMNT Electrolyte Packets

Top Pick

1,000mg sodium, 200mg potassium, 60mg magnesium. Zero sugar, zero carbs.

The gold standard for keto electrolytes. Sodium-forward ratio matches what keto dieters actually lose.

View on Amazon

Magnesium Glycinate (400mg)

Highly bioavailable magnesium form that doesn't cause digestive issues.

Most keto dieters are deficient. Supports sleep quality, muscle recovery, and insulin sensitivity.

View on Amazon

Potassium Chloride Salt Substitute

Used as a cooking salt replacement. Provides potassium without pills.

Easiest way to add potassium naturally through cooking without supplementing separately.

View on Amazon

Himalayan Pink Salt

Unrefined salt with trace minerals. Add liberally to food and water.

Sodium is the most critical electrolyte to replace on keto. Don't fear salt — you need more of it.

Healthy Fats & Oils

Fat is your primary fuel on keto. Not all fats are equal — prioritize stable saturated and monounsaturated fats for cooking, and use MCT oil to boost ketone production rapidly.

Healthy Fats & Oils products

MCT Oil (C8/C10)

Top Pick

Medium-chain triglycerides that convert to ketones faster than any other fat.

Rapidly raises blood ketones, suppresses hunger, and provides quick cognitive fuel. C8 is the most ketogenic.

View on Amazon

MCT Oil Powder

Same benefits as MCT oil in a powder form. Easy to mix into coffee or shakes.

Better tolerated than liquid MCT for beginners. No digestive discomfort when starting.

View on Amazon

Grass-Fed Ghee

Clarified butter — pure fat with zero casein or lactose. High smoke point.

Ideal for high-heat cooking. Higher CLA and butyrate content than conventional butter.

View on Amazon

Extra Virgin Olive Oil

Cold-pressed, unrefined. Rich in oleic acid and polyphenols.

Best oil for cold use — dressings, drizzling. Do not use for high-heat cooking.

View on Amazon

Avocado Oil

Neutral flavor, very high smoke point (520°F). Ideal for cooking.

The best all-purpose cooking oil on keto. Stable at high heat, rich in monounsaturated fat.

View on Amazon
Protein Sources

Protein on keto should be adequate but not excessive. Aim for 25% of calories from protein to preserve muscle without triggering gluconeogenesis. Quality and bioavailability matter.

Protein Sources products

Whey Protein Isolate

Essential

90%+ protein, minimal lactose and fat. Fast-digesting.

Best post-workout protein. Look for unflavored or naturally sweetened with zero added sugar.

View on Amazon

Collagen Peptides

Hydrolyzed collagen from bovine sources. Dissolves in hot or cold liquid.

Supports joints, skin, and gut lining. Not a complete protein but pairs well with whey.

View on Amazon

Canned Sardines in Olive Oil

Wild-caught, zero carbs, loaded with omega-3s and protein.

One of the most nutrient-dense keto foods available. Cheap, shelf-stable, anti-inflammatory.

View on Amazon
Supplements

A handful of supplements have strong evidence for supporting ketogenic adaptation, reducing deficiency risk, and improving body composition outcomes.

Supplements products

Vitamin D3 + K2 (5,000 IU)

Top Pick

Fat-soluble vitamins best absorbed with dietary fat — ideal for keto timing.

Most people are deficient. D3 supports immunity and mood; K2 directs calcium to bones.

View on Amazon

Omega-3 Fish Oil (EPA/DHA)

2–4g combined EPA + DHA daily from triglyceride-form fish oil.

Reduces systemic inflammation, improves lipid profiles, and supports brain function on keto.

View on Amazon

Creatine Monohydrate (5g/day)

The most researched sports supplement. Enhances strength and muscle retention.

Keto can deplete muscle creatine stores. Supplementing maintains performance during adaptation.

View on Amazon

Berberine (500mg)

Plant alkaloid with insulin-sensitizing and glucose-lowering effects.

Enhances fat loss and metabolic health. Often called 'natural metformin' in research literature.

View on Amazon

Zinc + Copper

Paired for proper balance. Zinc supports testosterone and immune function.

Keto dieters eating lots of red meat may be zinc-rich but copper-deficient without pairing.

Ketone Testing

You can't manage what you don't measure. Testing blood ketones is the only accurate way to confirm you are in ketosis. Urine strips are convenient but unreliable after the first few weeks.

Ketone Testing products

Keto-Mojo Blood Ketone Meter

Top Pick

Dual blood ketone + glucose meter. Tests BHB and glucose with one device.

The most accurate and cost-effective way to confirm ketosis. Strips are cheaper than competitors.

View on Amazon

Biosense Breath Ketone Monitor

Non-invasive acetone breath meter. No strips or blood required.

Best for daily monitoring without ongoing strip costs. Correlates well with blood BHB over time.

View on Amazon

Ketone Urine Strips

Dip strips that detect acetoacetate in urine. Cheap and easy.

Useful during the first 1–2 weeks. After fat adaptation, urine strips become unreliable.

Keto Snacks & Foods

Real, whole foods are always preferred. But these shelf-stable and convenient keto foods make it easier to stay on track when you are traveling or short on time.

Keto Snacks & Foods products

Epic Meat Bars

Recommended

Whole-food meat bars with 1–3g net carbs. No soy, no gluten.

Best grab-and-go keto protein snack. Cleaner ingredient list than most protein bars.

View on Amazon

Lily's Dark Chocolate Chips

Stevia-sweetened chocolate with 1–3g net carbs per serving.

Satisfies chocolate cravings without spiking blood sugar. Great for keto fat bombs.

View on Amazon

Pork Rinds (Chicharrones)

Zero carbs, high fat and protein. Extremely crunchy.

The ultimate keto chip replacement. Also high in glycine, which supports collagen synthesis.

View on Amazon

Whisps Cheese Crisps

100% parmesan or cheddar baked into crisps. 1g carb per serving.

Satisfying crunch with no fillers. Great with dips like guacamole or sour cream.

View on Amazon
Energy & Focus

Keto naturally improves focus and mental clarity once fat-adapted. These products extend and enhance that effect — particularly useful during the adaptation window when energy can dip.

Energy & Focus products

Bulletproof Ground Coffee

Classic

Lab-tested for mycotoxins. Clean single-origin coffee for bulletproof preparation.

Provides sustained energy without a glucose spike. Pairs perfectly with MCT oil and ghee.

View on Amazon

Four Sigmatic Mushroom Coffee

Coffee blended with lion's mane and chaga mushroom extracts.

Lower caffeine than regular coffee with added nootropic benefit from lion's mane for focus.

View on Amazon

Exogenous Ketone Salts (BHB)

BHB salts that raise blood ketones for 2–3 hours without dietary restriction.

Useful during keto induction to ease adaptation symptoms. Not a replacement for dietary ketosis.
