Product description
What’s included: a 2 lb container of 100% micellar casein protein powder in Chocolate flavor. This formula uses micellar casein — a milk-derived protein that digests more slowly than whey — to provide prolonged amino acid release over several hours.
Serving facts and nutrients: each scoop supplies 24 grams of micellar casein protein and about 9 grams of naturally occurring essential amino acids (EAAs). The powder also contributes key minerals, delivering approximately 85 mg of magnesium and 11 mg of zinc per serving to complement daily protein intake.
How to use: mix one scoop with 8–14 fl oz of cold water, milk, or another preferred beverage. Use less liquid for a thicker, milkshake-like consistency or more liquid for a thinner drink. It’s commonly used 30–60 minutes before bed or as a between-meal protein boost to help support overnight recovery and longer-lasting fullness.
Texture and mixing: the product is designed to dissolve with minimal equipment — it can be mixed in a glass with a spoon or blended in a shaker or blender. Expect a creamy, somewhat dense texture typical of slow-digesting casein powders.
Pros
- Sustained amino acid release for overnight recovery
- Provides EAAs plus magnesium and zinc per serving
- Creamy, milkshake-like texture when mixed cold
Cons
- Thicker, slightly grainy mouthfeel compared with whey
- Some find the flavor on the sweeter side
- Takes more vigorous mixing than whey to dissolve fully
VerdictA dependable micellar casein powder formulated for steady overnight amino acid delivery. It supplies 24 g of slow-digesting milk protein per scoop, a useful dose of essential amino acids, and added magnesium and zinc. Texture leans toward thick and slightly grainy, but it mixes into a satisfying, creamy shake when prepared cold. Recommended for anyone seeking longer-lasting satiety and steady musc

Leanne Henderson 5/5
Tasty chocolate, a little grainy
Flavor is enjoyable and it mixes well in room-temperature water with a shaker. Texture is mildly grainy, which I expected. Container has extra headspace but you still get the full weight of product.

Helped correct low protein levels
Added this after bloodwork showed low protein; levels normalized within a month. No digestive issues and it dissolves quickly in water, with a pleasant taste and minimal aftertaste.

Good flavor, easy on the stomach
Smooth taste and not overly thick. Easy to drink and doesn’t cause bloating for me. I’ll buy more when I run out.

Charlotte 5/5
Chalky but filling
A touch chalky, but tastes fine when mixed with milk. The aftertaste isn’t my favorite, but mixing with PB2 helps. It keeps me full and doesn’t upset my stomach.

Thickens in almond milk
Love the flavor. It thickens a lot when mixed with almond milk and doesn’t dissolve perfectly by hand, but a blender or milk frother sorts it out.

Overnight recovery and sustained fullness
Designed for slow digestion, each 33–34 g serving gives 24 g of micellar casein and 9 g EAAs to aid muscle repair while you sleep. Low in fat and sugar, it mixes with water or milk depending on your texture preference.

Reliable slow-release protein
This micellar casein offers a steady amino acid release ideal for bedtime. Each serving provides 24 g of casein for prolonged recovery and around 9 g of EAAs. Keeps you full longer and supports overnight muscle repair.

Great for a bedtime shake
Makes a thick chocolate shake that’s perfect before sleep. If you like sweet treats, it can double as a dessert replacement.

BT 4/5
Keeps me satisfied all day
I switched from whey and prefer the longer-lasting effect. One scoop carries me from breakfast to dinner. It blends with effort and produces a thick, milkshake-like drink I enjoy.

Disappointed with flavor intensity
I expected a milder taste but found it overwhelmingly strong. A regular shaker couldn’t thin it enough for me; despite the high protein, I regretted this purchase.
