Micellar Casein
NutraBio · 25g Protein · 120 Calories · 2lb · $45.99
NutraBio Micellar Casein is a 100% micellar casein protein that digests slowly over several hours, built to supply a steady release of amino acids overnight or between long gaps in meals.† Each 32.5g scoop delivers 25g of protein, 120 calories, 2g of carbs, and 0.5g of fat with no proprietary blends, no fillers, and full label transparency — NutraBio’s standard.† It is the slow protein to pair with a fast whey, taken before bed to support recovery while you sleep.†
Per 1-Scoop (32.5g) Serving
Overnight Recovery
Slow amino release supports muscle recovery through the sleeping hours.†
Steady Amino Supply
Supports a sustained amino acid level for 5 to 7 hours instead of a short spike.†
Supports Lean Muscle
Casein before bed is one of the most-studied strategies for supporting muscle protein synthesis overnight.†
Appetite Control
The gel-forming digestion is filling, which helps late-night hunger on a cut.†
Fills Meal Gaps
A scoop between widely spaced meals keeps protein steady on long work days.†
Thick, Dessert-Like Shake
Casein mixes thick; blended with a little milk it eats like pudding, which makes it an easy nightly habit.
Serving Parameters
Mix 1 scoop with 8 to 12 oz of cold water or milk and drink 30 to 60 minutes before bed, or between meals when the next protein feeding is several hours away.† Casein mixes thicker than whey — use more liquid for a thinner shake, or less and let it sit in the refrigerator for a pudding texture.
Use 1 serving daily as a night-time protein, or up to 2 servings to cover long gaps between meals. Pair it with a fast whey like Precision Protein after training; the two proteins cover opposite ends of the recovery window.† Store in a cool, dry place with the lid tight. On a cut, the bedtime casein shake doubles as the dessert that keeps late-night hunger from breaking the diet; on a bulk, blend it with whole milk and peanut butter for a slow-digesting 400-calorie meal before sleep.† Either way the goal is the same: no 8-hour gap in amino acid supply while the body does its repair work.†
Micellar Casein is the slow protein. Add the fast one for post-workout, sleep support for the same window casein covers, and creatine for the training that drives it all.

What is NutraBio Micellar Casein?
NutraBio Micellar Casein is a 100% micellar casein protein powder sold in a 2lb tub. Each 32.5g scoop delivers 25g protein, 120 calories, 2g carbs, 1g sugar, and 0.5g fat, with no proprietary blends or fillers. It digests slowly to support overnight recovery and a steady amino acid supply.†
What is the difference between casein and whey?
Both come from milk. Whey digests fast — amino acids peak within about an hour — which suits post-workout. Casein forms a gel in the stomach and releases amino acids over 5 to 7 hours, which suits bedtime and long gaps between meals.† Most lifters use both.
When should I take Micellar Casein?
30 to 60 minutes before bed is the standard use. It also works between meals when the next protein feeding is hours away. It is not the best choice immediately post-workout — use a fast whey there.†
Will casein help me build muscle?
Casein before bed supports muscle protein synthesis through the night, when you would otherwise go 7 to 9 hours without protein.† Combined with training and adequate daily protein, it supports lean muscle and recovery.†
Does casein cause fat gain?
No more than any other 120-calorie food. Casein is high protein, low carb, and nearly fat-free; the calories count toward your daily total like anything else. Many users on a cut use it specifically because it is filling at night.†
What flavors are available?
Pre Nutrition stocks NutraBio Micellar Casein in Alpine Vanilla, Dutch Chocolate, and Strawberry Ice Cream. Use the flavor selector above.
Is NutraBio Micellar Casein lactose-free?
No. Micellar casein is a dairy protein and contains milk. It is lower in lactose than whey concentrate, but users with lactose intolerance should assess tolerance with a half scoop.
