KETO VERDICTYES

Casein protein powder is keto-friendly, typically ~2–4g net carbs per 100g with ~80g protein. Unlike whey’s fast absorption, casein digests slowly for sustained amino acid release—great for nighttime or between-meal protein while maintaining ketosis.

WHY IT'S KETO-FRIENDLY

  • Low net carb content (~2–4g/100g) is highly keto-compatible
  • Slow-digesting protein provides ~6–8 hours of amino acid release
  • Complete amino acid profile supports muscle synthesis and recovery
  • Ideal pre-bed or between meals to prevent overnight muscle breakdown
  • Generally gentler glucose/insulin impact than fast-absorbing proteins
  • Useful during intermittent fasting windows to preserve lean mass

HEALTH BENEFITS

  • Complete protein with all nine essential amino acids
  • Forms a stomach gel that may enhance satiety
  • May contain casomorphins with calming effects for some individuals
  • Supports muscle recovery and growth over extended periods
  • Can reduce muscle protein breakdown during sleep
  • Provides calcium and phosphorus for bone health

PREPARATION SUGGESTIONS

NIGHTTIME SHAKE

Blend with heavy-cream and keto sweetener before bed to sustain amino acid availability overnight.

PUDDING

Mix with almond-milk-unsweetened and rest 5–10 minutes to thicken; top with almonds and cacao nibs.

SLOW-RELEASE SHAKE

Blend with coconut-milk-full-fat and mct-oil for a steady-energy mid-day shake.

KETO BAKING

Use unflavored casein to add structure/protein to low-carb muffins, brownies, or pancakes.

POST-WORKOUT MIX

Combine with whey-protein (fast) for immediate + sustained amino delivery.

PEANUT BUTTER PROTEIN BARS

Stir with peanut-butter, coconut oil, and keto sweetener; chill into bars for easy snacks.
