Casein protein by Legion Athletics is one of the bestselling protein powders on the market for several reasons:
- It’s digested slowly, resulting in a steadier, more gradual release of amino acids into the blood. 
- It’s absorbed well by the body.
- It’s rich in essential amino acids, which are vital to recovery and muscle building.
- It tastes good.
Like whey, casein protein comes from milk, and research shows that it’s just as good as whey for general supplementation needs. 
Unlike whey, however, casein digests slowly—one serving of CASEIN+ provides your body with muscle-building amino acids for up to eight hours.
This means CASEIN+ is particularly suited to prebed nutrition, when your body’s muscle-building machinery normally lies dormant for a number of hours.
By having a serving of a slow-burning protein like casein before you go to bed, you keep that machinery humming throughout the night, and research shows this improves postworkout recovery and increases muscle and strength gains over time. 
For instance, in a study conducted by scientists at Maastricht University, 15 young, active men were divided into two groups:
- Group one drank 40 grams of casein protein 30 minutes before going to bed.
- Group two drank water 30 minutes before going to bed.
Everyone did the same lower-body workout and otherwise ate the same throughout the day, and then, researchers took blood samples throughout the night to measure protein absorption and muscle protein synthesis rates.
They found that most of the protein eaten before bed was absorbed and that protein synthesis was 22% higher in group one.
Although this study didn’t directly measure muscle growth, it’s almost guaranteed that the presleep protein intake would lead to more muscle growth over time, as muscle protein synthesis is the key mechanical driver of muscle gain.
When we set out to create CASEIN+, we wanted to achieve several things.
We wanted to maximize the amount of protein per scoop and minimize the carbohydrate and fat.
If you’re like us, you don’t like “wasting” calories on carbs and fat in protein powders. We’d rather eat those calories, not drink them.
We wanted it to contain no artificial sweeteners or flavors, GMOs, or other unnecessary junk.
While artificial sweeteners may not be as harmful as some people claim, research suggests that regular consumption of these chemicals may indeed be harmful to our health. 
The safety of MSG is the subject of ongoing scientific discussion, but research shows that some people experience uncomfortable symptoms upon eating it and that it can be neuroactive in the brain when consumed in high dosages. 
And GMO foods certainly aren’t as dangerous as alarmists would have us believe, but there are unanswered questions about how they might affect our health when consumed in large amounts over time.
We wanted it to come from cows that weren’t treated with hormones or antibiotics.
Similar to artificial sweeteners, milk from cows treated with such drugs may not be as bad as we’ve been told, but there is scientific evidence that it may increase the risk of disease in humans. 
We wanted it to have an outstanding taste and mouthfeel.
Too many all-natural protein powders taste mediocre at best, so we wanted to create something you will actually look forward to drinking.
Well, that’s exactly what we’ve done with CASEIN+.
