We had a lot of options to pick from when it came to proteins, but at PROGENEX we want to provide the best in sports nutrition, so we chose a micellar casein protein powder to infuse PROGENEX Cocoon with. The ingredients in PROGENEX Cocoon have been shown in studies to:

  • Stimulate protein synthesis (Tipton, 2004)
  • Increase lean muscle mass and strength (Demling, 2000), (Willoughby, 2007)
  • Prevent muscle wasting (Boirie Y, 1997)
  • Speed recovery (Cermak, 2012)
  • Improve immunity (Gregory, 2008)
  • Enhance satiety (Abou-Samra, 2011)
  • Reduce blood pressure (Cadee, 2007)
  • Improve Sleep (Hartman, 1982)
  • Boost Mood (Thomson, 1982), (Levitan, 2000)


Nighttime recovery is crucial for daytime performance and success. PROGENEX Cocoon, the best micellar casein protein powder, combines just what your body needs for a deep, restorative, and reparative sleep so that you wake up feeling refreshed, rejuvenated, and recovered—ready to tackle stress, rise above the daily grind, and attack your most grueling workouts.PROGENEX Cocoon is a special nighttime formula featuring micellar casein and Metamorphagen™. Similar to the curds and whey that Little Miss Muffet ate in the popular nursery rhyme, our PROGENEX Cocoon nighttime recovery is packed with one of the best forms of protein available—casein. But better than that plain cottage cheese Miss Muffet was eating, Cocoon is tastier and longer lasting. As a slow digesting nighttime protein, the micellar casein stimulates protein synthesis through a sustained release of BCAAs (Leucine, Isoleucine, and Valine) and other amino acids throughout the night, promoting better sleep and muscle building while preventing muscle wasting. This slow, steady drip of amino acids is not only critical for protein synthesis but is also crucial for immune system support.Additionally, PROGENEX Cocoon is packed with tryptophan, that little piece of Thanksgiving turkey that leaves you just a tad drowsy. Tryptophan is an essential amino acid for protein production and is also a precursor to rest inducing hormones. Just 30 years ago, tryptophan studies proved that consuming it helped reduce sleep latency (the amount of time it takes an individual to fall asleep) while at the same time promoting better sleep. Tryptophan has even been shown to help individuals with sleep disorders such as insomnia or sleep apnea.
