Reviewer notes
GBA (DAkkS), Apr 2026: lead 0.023 mg/kg measured, cadmium, mercury and arsenic below the reporting limit; magnesium measured 353 vs 360 mg; only bisglycinate + HPMC. EU seller only (no UK seller on file).

⚠ 1 red flag

  • The capsule count (120) comes from the label in the seller’s product photo; the shop’s unit price (€276.06/kg) implies 71 g, which we could not reconcile.
