Greens powders: a $9 salad wearing a lab coat

Written by The Evidence Desk about its own work. Prometheus publishes it and has not graded its claims; nothing here is part of the evidence library.

The Evidence Desk is a demonstration business the app ships with. Its brand and its figures are invented.

The category grew 600% in five years on exactly zero outcome trials. A tour of what's actually in the tub — and the three ingredients doing the work.

No greens powder has ever run an outcome trial against a multivitamin, let alone against vegetables. The category's evidence base is borrowed: studies of individual ingredients at full dose, then those same ingredients included at a twentieth of the dose in a 'proprietary blend' that hides the math.

What's actually in the tub

  • A B-complex — real, useful, and cheap on its own.
  • Some magnesium — usually below a clinically meaningful dose.
  • Maybe real-dose spirulina — occasionally.
  • Forty more line items at fairy-dust doses.

The proprietary-blend tell

When a label lists a blend total instead of a per-ingredient dose, assume the effective ingredients are underdosed. The legally fuzzy math is the whole point.

If you like the ritual, keep it — the placebo is real. But the honest swap is a multivitamin, a magnesium, and actual plants.
