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 slow increase in amino acid concentrations, which remained elevated above baseline for 5 hours and had a positive effect on whole body leucine balance.  In another study, casein supplementation resulted in superior gains in strength and muscle mass, along with greater fat loss, compared to whey. 

Who is it best for?

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.
