Eighty:20 contains a ratio of micellar casein (80%) to whey (20%) naturally found in milk. The blend of anti-catabolic slow absorbing protein (micellar casein) and anabolic fast absorbing protein (whey) was specifically formulated by reviewing new emerging and historic protein research for advanced lean muscle support.
The combination of micellar casein and whey stimulates muscle protein synthesis (MPS) for six hours, inhibits muscle protein breakdown (MPB), and has been scientifically proven to have greater nitrogen retention than whey or micellar casein alone.
It’s a common misconception fueled by product marketing that whey should only be consumed post workout and micellar casein only around bedtime. It is important to understand that this is not an accurate representation of the facts.
Research has proven that adding micellar casein to whey will not inhibit the fast absorption of whey or the desirable slow absorption of micellar casein.
For example, leucine from whey appears in blood plasma rapidly and is associated with an increase in whole body protein synthesis during the first 180 minutes (anabolic properties) with no significant effect on protein breakdown.
To complement whey protein, micellar casein results in a slower leucine appearance in blood plasma sustained over several hours, with smaller increases in whole body protein synthesis and significant and sustained decreases in muscle protein breakdown (anti-catabolic properties). Net whole body leucine is greater after ingesting micellar casein vs. whey.
