The Claim
In trained individuals, an 8-week daily supplementation of 54 grams of casein protein, consumed either in the morning or evening, does not significantly affect muscular strength or endurance, as assessed by 1-repetition maximum in the bench press and the number of repetitions to failure at 60% of 1-RM, when resistance training routines remain constant.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you're already working out, taking 54 grams of casein protein every day for 8 weeks—whether in the morning or at night—won’t noticeably change your strength or how long you can keep lifting weights, as long as your workouts stay the same.
See the scientific wording
In trained men and women, 8 weeks of 54 grams daily casein supplementation—whether taken in the morning or evening—has no significant effect on muscular strength or endurance, as measured by 1-repetition maximum bench press and repetitions to failure at 60% of 1-RM, when training routines are unchanged.
What the research says
1 studyStudy: Casein Protein Supplementation in Trained Men and Women: Morning versus Evening
The study looked at whether taking casein protein in the morning or night affects fitness in people who already exercise, and found no big changes in body or performance, which matches the claim.
