Carnitine comparison: lab tests, heavy metals and price (UK + EU)
2 products, 1 lab verified: a current independent lab report we have checked. Others have an outdated report, reporting limits too high to be useful, or no report. Figures come only from published reports and seller pages; “—” means we have no data, never an estimate.
Public CoA is pass/fail without clear numeric metal values in extract — Partial.

Heavy-metal colours:0.01 Well under the EU limit (below half) or below detection▲1.6 Near the EU limit (half the limit up to the limit)■3.2 Over the EU limit0.30 Grey: no EU limit (arsenic), not tested, or the lab’s reporting limit is above the EU limitEU 2023/915 limits for food supplements: lead (Pb) 3.0, cadmium (Cd) 1.0, mercury (Hg) 0.10 mg/kg. Values in mg/kg. NT = not tested; c = calculated by us from µg per serving.
Pb = lead, Cd = cadmium, Hg = mercury, As = arsenic, all in mg/kg. “<” means below the lab’s detection limit. Pass* = certificate states compliance without a figure. — = no data. Label match = the lab measured the active content against the label. The lab name, full notes and per-serving details are on each product page.
