Micellar Casein Protein, All Natural Pasture Raised Hormone Free Soy Free

- +

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.

*  Grass (Forage) Fed -Grass and forage shall be the feed source consumed for the lifetime of the ruminant animal, with the exception of milk consumed prior to weaning. The diet shall be derived solely from forage consisting of grass (annual and perennial), forbs (e.g., legumes, Brassica), browse, or cereal grain crops in the vegetative {pre-grain) state. Animals cannot be fed grain or grain byproducts and must have continuous access to pasture during the growing season. Hay, haylage, baleage, silage, crop residue without grain, and other roughage sources may also be included as acceptable feed sources.

Routine mineral and vitamin supplementation may also be included in the feeding regimen. If incidental supplementation occurs due to inadvertent exposure to non-forage feedstuffs or to ensure the animal's well being at all times during adverse environmental or physical conditions, the producer must fully document (e.g., receipts, ingredients, and tear tags) the supplementation that occurs including the amount, the frequency, and the supplements provided.

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.

Protein packed flavors

Micellar casein is the slowest digesting of Muscle Feast’s protein offerings. The high quality and slow-digesting characteristics of our natural micellar casein make it a great option to have right before bed for overnight muscle recovery. You can easily mix it with water or milk. You can even add it to some of your favorite fruits, oats, etc. to boost the protein content of snacks.

Both chocolate and vanilla variants come with 19 grams of protein per serving and leave a bold impression on your taste buds. With both offering a rich rush of flavor, these variants of natural micellar casein are definitely some of the best micellar casein options to try.
