Casein Protein 

According to a 1968 study in The Journal of Clinical Investigation, getting enough sleep is a must for gaining muscle because that’s when your growth hormone (GH) levels peak. That’s where casein comes in. A major protein found in milk; casein protein is a better choice than traditional whey due to its slow digestion and absorption rate.  

Prostar 100% Casein by Ultimate Nutrition provides a sustained amino acid release for up to seven hours, with 24 grams of protein and 60% of your daily calcium needs per serving. Plus, it’s available in three delicious flavors; chocolate creme, strawberry, and vanilla cream.  

You could literally treat yourself and build muscle while you sleep. What could be more epic for your gains than that? 

Flaxseed Oil 

According to a 2023 article in the European Journal of Medical Research, flaxseed provides essential fats that may help enhance recovery and fat loss. These healthy fats help slow digestion, preserving muscle fiber protein while you sleep.  

Try Ultimate Nutrition Flaxssed Oil for an optimal balance of Omega-3 and Omega-6 fatty acids, helping increase metabolic rate and improving metabolism. 

Arginine  

You might know arginine as the amino acid you take right before workouts to get that incredible pump. Arginine boosts nitric oxide levels during activity, but it also helps promote a greater GH release during sleep according to a 2020 article in Nutrients.

Glutamine 

Another star amino acid for sleep, glutamine prevents muscle breakdown, boosts immunity, and can even help increase fat burn. It can also help release GH, just like arginine.

ZMA 

ZMA is a combination of zinc, magnesium aspartate, and vitamin B6. It’s a triple threat for increasing testosterone, boosting immunity, and promoting brain health, all of which benefit muscle growth and overall health.
