Recovery supplements for Masters runners

I second it in some way

Twenty years ago, I saw a Harvard study that changed forever my perspective on supplements. Even back then, I wouldn't accept a study's conclusions because authors can be biased in how they analyse their data.

Anyway, the study looked at caffeine and concluded that it had no performance benefit. The individual data showed a strikingly different perspective. 80% of participants had no benefit or even a reduced performance with caffeine so the study concluded that caffeine had no benefit. However, the remaining 20% was a different story. 15% had a significant benefit. 5% had an outstanding benefit. Their cycling time to exhaustion increased by nearly 50%.

My takeaway was that for a variety of reasons, some people are underperformers and some are super performers when adding a supplement.

My point is that as we age, the cells in our bodies become less efficient. Your cells might be deficient in some nutrient and a specific supplement might provide a noticeable benefit, but it might provide no benefit to a friend at the same age and fitness. You are an experiment of one. The supplements listed in this thread might help you recover or they might not. You have to test them to find out.

I feel like I get better REM & deep sleep with ZMA. Plus it is super cheap. I take it with dinner for best results. YMMV.
