FAQ
Where can I see a D3 + K2 Certificate of Analysis?
On each Lab verified product page we link the report we opened (lab name, date, batch where given, and the PDF or lab image). Start with the Lab tested D3 + K2 category or the comparison table; Lab verified products rank first.
Which D3 + K2 has the lowest heavy metals in your data?
Several EU reports show all four metals below the lab’s reporting limits, including edubily drops (GBA, Oct 2026), MoleQlar capsules and drops (GBA, 2026) and Sunday Natural 2,500 IU + 100 µg drops (GBA, May 2026: lead <0.020, cadmium <0.010, mercury <0.010, arsenic <0.040 mg/kg). Among measured (non-<) lead values, Bare Biology sprays report lead <0.050 mg/kg (Supplement Certified, May 2026) and Sunday Natural 5000 IU drops measured lead 0.19 mg/kg (GBA, May 2026), still far below the EU limit of 3.0 mg/kg.
Which lab-tested D3 + K2 can I buy from a UK seller?
Bare Biology Beam & Balance Vitamin D3 + K2 Peppermint and Unflavoured sprays (UK company; Supplement Certified / NRCI CoAs, 28 May 2026) and three Sunday Natural products on sunday-natural.co.uk (German brand with a UK shop): Vitamin D3 + K2 MK-7 2,500 IU + 100 µg drops, 5000 IU + 200 µg drops and Vitamin D3 5000 IU + K2 MK7 100 µg tablets (GBA Hamburg reports, May 2026). Check delivery origin and any import charges on EU-brand UK sites.
Where can I buy lab-tested D3 + K2 in the EU or Spain?
edubily (Germany) publishes GBA PDFs for its D3 & K2 Tropfen and Vitamin D3 mit K2 Kapseln; MoleQlar and VitaMoment (Germany) publish GBA reports for capsules and/or drops. We have not separately checked delivery to every EU country; use the seller link on each product page.
What can vitamin D and vitamin K claim under EU/UK law?
Authorised claims for vitamin D include that it contributes to normal absorption/utilisation of calcium and phosphorus, to the maintenance of normal bones, teeth and muscle function, and to the normal function of the immune system. Authorised claims for vitamin K include contribution to normal blood clotting and to the maintenance of normal bones. These claims are about the nutrients in general when the food is at least a source, not a brand. This page is not medical advice.
Is there a legal heavy-metal limit for D3 + K2 supplements?
Food supplements in the EU must stay under Regulation (EU) 2023/915 maximum levels: lead 3.0, cadmium 1.0 and mercury 0.10 mg/kg; Great Britain applies the same levels for supplements. There is no specific EU limit for arsenic in supplements. Every measured result on our Lab verified D3 + K2 list is within the three metal limits.
