Grass Fed Hormone Free Micellar Casein


Muscle Feast Micellar Casein digests slowly to provide you with a sustained increase in amino acids to prolong muscle protein synthesis. Micellar casein is isolated from milk by filtration, preserving the structural integrity of the protein molecule. It provides 18.2-19.3g of protein per serving (depending on flavor). It has 3.4g of naturally occurring BCAAs per serving and offers many other biologically active compounds that have direct immune and physiological benefits. While it is best to take micellar casein before bed, it is also an ideal choice as a protein-rich snack.

Micellar Casein


What is Micellar Casein?

Unlike the whey isolates and concentrates Micellar Casein digests and absorbs more slowly. Because it is digested slowly and leads to a relatively sustained increase in amino acids, micellar casein seems to inhibit protein breakdown to a greater extent than whey protein and prolongs muscle protein synthesis (MPS) times. However, it does not elevate amino acid levels in the blood to the extent whey proteins do. Micellar casein, as opposed to caseinate, is isolated from milk by filtration rather than by use of acid or heat. This filtration method preserves the structural integrity of the protein and provides many biologically active compounds that have direct immune and physiological benefits.

What does the research say?

A study conducted by Boirie and Dangin gave subjects a 43-gram dose of casein and measured amino acid levels for several hours. The casein caused a gradual increase in amino acid concentrations, which remained elevated above baseline for 5 hours and had a positive effect on the whole body leucine balance. In another study, casein supplementation resulted in superior gains in strength and muscle mass, along with more significant fat loss, compared to whey.

Who can benefit from Micellar Casein?

Micellar casein is a good fit for anyone who wants a slower digesting protein source to prolong muscle protein synthesis times beyond that of whey proteins.

How quickly does it digest/absorb and raise amino acid levels?

When consumed, micellar casein elevates amino acid concentrations in the blood gradually and peaks out after ~30 minutes, at which point amino acid levels remain consistent and can last up to 7 hours depending on the dose taken.

When is the best time to take it?

Micellar Casein is best taken before bed to provide a sustained and prolonged release of amino acids to help the body maintain a positive nitrogen balance. It is also an ideal choice when an individual may go 4-5 hours without eating.

Great Product! I have been using this product for over 1 year and have recommended to fellow military members. Thanks!

Best casein (and protein company) out there

I've been looking for good casein powder for a while. ON makes some with good ingredients, but it's overpriced and is only 60-some percent protein. MyProtein makes casein, but it comes either unflavored or artificially flavored. And every other casein powder I've found falls into one of these categories: overpriced or bad ingredients.

I was pretty much sold on Muscle Feast when I found it, but I wanted to try some before buying it. I emailed the company, and Sean Gillespie offered to send me some samples free of charge, after some back and forth to determine what I was looking for. So top notch customer service, reasonable price, clean ingredients, high percentage protein, and on top of all that, a military veteran discount. I'll definitely continue buy my protein from Muscle Feast.

Quality casein

My trainer made me get casein while everyone told me it won’t taste the way whey shakes do, which is true, but the chocolate plus a tablespoon of almond butter tastes great! No problem taking it before bed and I don’t wake up starving.


Grass Fed Hormone Free Micellar Casein

Great Stuff

Got the chocolate flavor and really liked it. Alongside the isolate protein I think it makes for a great recovery tool in between workouts.
