## Overview

Optimum Nutrition Gold Standard 100% Micellar Casein offers 24 grams of slow-digesting protein per serving, enriched with nearly 5 grams each of BCAAs and glutamine. Designed for overnight muscle recovery and prolonged satiety, this premium chocolate-flavored powder supports sustained muscle repair and fullness through hours without food. Trusted by thousands, it’s the go-to choice for professionals seeking effective, high-quality nighttime nutrition.

## Description

Faster digesting protein is desirable immediately before and after exercise to help refuel recovering muscles, but slow digestion and absorption may be more beneficial at other times including bedtime when your body typically goes for hours without food. Casein products are acid sensitive and thicken in the stomach. Compared to some other proteins, it can take longer for our Gold Standard 100% Casein™ to be broken down into its amino acid subcomponents. By using only premium micellar casein as a protein source, we've created a formula that sets the standard for slow digesting protein support. 24g of Micellar Casein

Review: Siempre la mejor calidad de Gold Standard, tambien con un buen sabor. Relacion Precio / Calidad, un poco alto el precio. Pero considerando todo, vale la pena. Solo Optimum Nutrition para mi proteina! Caseina con Avena no esta mal y este sabor de chocolate hace la avena un poco mas aguantable... ;)
Review: I’m a huge fan of Optimum Nutrition whey, and this product did not disappoint either. The powder dissolves easily and mixes smoothly, with a chocolate flavor that tastes really good — definitely enjoyable to drink. One thing to keep in mind is that this casein requires more liquid per scoop compared to whey to achieve the desired consistency, but that’s typical for slow-digesting proteins. It works perfectly for overnight muscle recovery and helps keep you full longer. Overall, a high-quality casein protein that delivers on taste, mixability, and effectiveness. A reliable choice for anyone looking to support muscle recovery or stay satiated overnight.

## Questions & Answers

**Q: why this product wont dissolve in milk? i shake it over 30 second and i can still taste the powder so thick**
A: There’s your problem, shake for 45 seconds. You’re leaving all those reps on the table. Remember, explosive out but a controlled return. 12 shake reps should take you 45 seconds if you’re doing it right. And breath. Contract. Feel the muscles. Quit leaving those reps on the table.

**Q: does this have gluten in it**
A: Although it maybe doesn't have gluten, people with gluten sensitivities or Celiac Disease should avoid the enzyme, Casein. I have Celiac Disease and this would "kill" me!

**Q: My container did not have a scoop in it. How much powder to I use for a shake?**
A: It's approximately a 1/4 of a cup (not exactly), but I'd bet there's a scoop in the bottom of the container somewhere, they sometimes sink to the bottom of the container...  It's placed in these containers by a computer system, not a person so chances of a mistake are minimal.

**Q: Does anyone know if this is 100% Micellar?**
A: No, it has calcium caseinate as the second protein source.

Excellent product, delicious, the chocolate is flavoursome but not too rich, loads of protein and low calorie. My gym trainer told me Casein is best when using this as a meal replacement.
