Rule 1 Casein - Made up of predominantly on micellar casein, Rule 1 Casein will give you 7 hours of night time fuel for your muscles to grow and recover. Rule 1 Casein allows the protein to feed your muscles during sleep. This form of casein is less acidic than other casein-based proteins, reducing the body’s tendency to increase its overall acidity from this protein powder.
When To Take Rule 1 Casein
Casein is generally seen as a nighttime protein. Quite the opposite to whey isolates and blends that digest within the hour, casein can take up to 8 hours. Some would use this slow-digesting protein in the day in an attempt to stay fuller for longer, however, such a slow-digesting milk-based product can cause stomach discomfort through the day. This is why casein has become almost exclusively known as a night-time protein. Your body takes full advantage of the 8 hour digestion while sleep, allowing the muscles to be fed over that period of time.
Rule 1 Casein Best Flavours
Rule 1 casein keeps things nice and simple with chocolate and vanilla, these flavours are easy to get down nice and quickly before bed and aren't too intrusive on other ingredients you may choose to add to your liquid dessert.

SLOW-RELEASE MICELLAR CASEIN FORMULA
Even in our fast-paced world, there are times when it pays to slow down. Take between meals and bedtime for example. During these occasions, you want a protein that takes its time. Something to hold you over until your next meal. A protein that breaks down more slowly, delivering its amino acids over several hours. R1 Casein is what you’re after.
Rule 1 Casein
- Does Rule 1 Casein include wheat or gluten?
No it does not contain gluten. Rule 1 Casein is gluten free. This is clearly marked on the product label.

I have it in the evenings of workout days.
In terms of taste i prefer the Maxxs; the R1 doesnt taste baaad its more of a neutral chocolate and definitely thicker and slightly more grainy than the Maxx's.
Maxxs tastes better but is slightly more expensive. Maxxs also has the Testosterone and GH boosters along with relaxants to help yah sleep.
This has some of the booster, like glutamine, but it all depends on what you want. Maxxs for growth and size, R1 more for weight management/loss IMO.
Side note; most night protein shakes ive tried, i wake up early and need to go bathroom. this i did not have the same result.
