Is “Greens” powder worth it?

Proprietary blends, undisclosed per-ingredient doses, and a health halo. No strong independent clinical-outcome evidence shows a greens powder replicates the benefits of eating vegetables. Fiber and real produce do the actual work.

The call

“Greens” products bundle dozens of ingredients behind a single proprietary-blend weight, so no individual ingredient is necessarily at a studied dose. Per-ingredient biomarker studies exist for some inputs, but there's no good evidence the finished powder delivers whole-vegetable outcomes. A not-worth-it call — with real (not zero) safety considerations.

Safety

Not risk-free: possible heavy-metal/contaminant load (buy third-party-tested if you buy anyway), high vitamin K (anticoagulant interaction) or vitamin A, iodine from seaweed inputs, and added stimulants/adaptogens. Check the label against your meds.

Dose that matters: — (the honest answer is food, not a scoop)
