Thirteen manufacturers across six countries. Marks are reproduced as supplied by each manufacturer and remain their property.
00 / Who makes it
Thirteen manufacturers, six countries.
Every Zandra product is made by one of these companies, to a specification we write and hold. Seven are in India, two in Slovenia, and one each in Sweden, Germany, Italy and South Korea. Some are among the largest producers in their field; AstaReal supplies the astaxanthin behind Astazandra, and Encube is a dermatology specialist, which matters for a company that is half dermatology.

How this list was checked
Every entry was verified against the manufacturer’s own site and, where possible, a regulator database in August 2026. Where a manufacturer supplied a certificate directly, the entry names the body that issued it. Where a company publishes none, or names a standard without naming the body that issued it, that is what this page says. One limit is worth stating: a US FDA listing is publicly searchable, but a TGA clearance is issued to the Australian sponsor rather than the manufacturer and is not published, so a TGA claim can be reported here but not independently confirmed by us or by you. We would rather show an incomplete audit than a tidy one.
01 / How they are chosen
The specification comes first.
A manufacturer is selected because it can meet a specification we have already written, not the other way round. Orals are made only at sites inspected against EU GMP or the equivalent standard of a PIC/S member authority. Topicals only at facilities compliant with ISO 22716. Where a manufacturer cannot hold a clinical dose in the format required, we do not reformulate downward. We change manufacturer.
01
Manufacturing floor
Pharmaceutical orals at sites inspected against EU GMP, or against the equivalent standard of a PIC/S member authority. ISO 22716 for topicals. Supplement lines at facilities holding a GFSI-recognised scheme, FSSC 22000 or IFS Food, or United States 21 CFR 111 supplement GMP.
02
Dosing
Dosed to European standards. We formulate to amounts the European Food Safety Authority (EFSA) has assessed for the nutrient, within its tolerable upper intake level where one exists. EFSA has not assessed our products.
03
Transparency
No proprietary blends. Full quantitative disclosure on orals. Full INCI on topicals, though not yet the concentration of each active.
04
Evidence
We state plainly what has and has not been trialled as a combination.
These four rows are self-assessed by Zandra and were last reviewed in August 2026. They are not certifications and no third party has awarded them. Met means it holds across every product and every manufacturer today. Partly met means it does not yet, and the row says where the gap is.
02 / What we bring
If you make something we should carry.
We in-license and register products for Ukraine, Uzbekistan, Georgia and India, and we sell them through our own field force rather than a third-party agency. If your product restores a depleted system and can carry a clinical dose, the conversation is short.
01
Registration
We hold registrations across four markets and take products through the dossier ourselves.
02
Our own field force
On payroll in every market, not contracted. The representative carries our name, not an agency’s.
03
In-licensing
We take on products that fit the Standard. We decline ones that do not, including profitable ones.
04
Contract manufacture
We do not offer it. We are the customer in that relationship, not the supplier.
Send the composition, the dose and the evidence. We will tell you in a week.
