Field Guide 11 — Supplement Shopping

The list that works is four items long. Everything else is supplemental noise.

Four supplements have substantial, repeated evidence for healthy training adults: creatine, caffeine, whey protein, and vitamin D if you are deficient. The evidence-based stack runs around twenty to thirty pounds a month; the typical influencer stack runs 150 to 400. Supplements are the most aggressively marketed corner of fitness, and almost everything on the shelf is decoration around those few things that actually do something. The shopping strategy fits on an index card: walk into the store with a list, buy nothing that is not on it, leave. Brad's cabinet holds twenty-three products; Susan's holds three; their training outcomes are identical. This is the filter you should have had before your first trip down the supplement aisle.
