Reviewer notes
Partial report: PLENUM Dr. Born (Ennepetal) analysis NAVI/16/10/25, 16 Oct 2025, batch 30067925095-1, reports metals only as “below” values at or near the legal limits (lead <3.0, arsenic <1.0, cadmium <0.5, mercury <0.1 mg/kg), so it shows compliance but not how low they are; microbiology unremarkable. A separate analysis (17 Oct 2025) measured 10.9 mg zinc per daily dose. EU seller (Germany).

⚠ 5 red flags

  • Metals are reported only as “below” values at about the legal limits, so the report shows compliance but not actual levels.
  • Report is from 16 Oct 2025 (about a year old).
  • Contains ashwagandha: see our ashwagandha safety note (Denmark bans it in food; Germany and France advise some groups not to take it).
  • The seller markets this product for men; we do not repeat marketing about hormones or libido. The only authorised testosterone claim in the UK and EU is that zinc contributes to the maintenance of normal testosterone levels in the blood.
  • The sample was sent in by the brand: check the batch number on your pack.
