When does supplementation timing really matter for performance?
As a former athlete, i spent countless hours on the field and in the gym, always looking for that extra edge. The conversations around supplementation timing seem to evolve, and I find myself reflecting on what I used to do back in the day. I read a lot of studies lately, like Schoenfeld and colleagues' work on protein timing (2013) where they discuss how nutrient timing can impact muscle protein synthesis (MPS). The effect sizes they found suggest that timing might matter, especially for those who train intensely.
Then I came across another paper by Helms et al. (2019) that examined the efficacy of protein timing. They concluded that while there are benefits, especially for serious lifters, the overall picture is more nuanced than the 'anabolic window' hype. It seems that consistent daily protein intake has a greater impact than the specific timing around workouts. I wonder if this applies across the board to other supplements like creatine or beta-alanine.
So my question is, when does the timing of supplementation genuinely impact performance versus when is it more about the total intake? For those of us who are no longer in the competitive arena but still pushing our limits, what should we really focus on? Is it more about being consistent with our intake or paying attention to when we take it? I'd love to hear thoughts from those who dive deep into the research.
Thanks for your insights!
