Protein supplements taken with meals was found to be more effective at improving resistance training compared to taking them between meals, according to a systematic review published in the journal Nutrition Review. On the other hand, protein supplements taken between meals may be more effective at increasing overall body mass.
A team of researchers from Purdue University aimed to evaluate the effect of protein supplement intake with meals and between meals on resistance training-induced body composition changes in adults. In conducting the study, the research team looked at a total of 34 randomized controlled trials with 59 intervention groups. All of the participants in the intervention groups were healthy adults with an average age of 19 years and older. Protein supplements, including bovine colostrum, casein, rice, soy, and whey, were included if they were isolates, concentrates, or hydrolysates taken alone or in combination with other nutrients and sources of proteins.
Results revealed that protein supplements consumed with meals increased lean mass, reduced fat mass, and increased the ratio of lean mass to fat mass over time better than when protein supplements were taken in between meals. On the contrary, taking protein supplements in between meals resulted in more body mass increases compared to consuming protein supplements with meals.
“The decrease in fat mass fits within the results of this systematic review, which showed a consistent increase in lean mass and an inconsistent change in body mass. Since lean mass consistently increased and body mass change was inconsistent, it follows that fat mass would decrease,” explained the research team.
In conclusion, taking protein supplements with meals may be more effective for weight control than consuming them between meals in adults who are undergoing a resistance training routine. The findings of the review indicated the importance of timing of protein supplement intake, which relies on the body weight and body composition goal of a person. (Related: Feeling old?

There are three common forms of protein powders: concentrates, isolates, and hydrolysates. They come from a variety of sources. Here are some types of protein powder supplements you can try:
