Ancestral-nutrition products are sold almost entirely on provenance. That makes provenance the thing most worth verifying — and the thing most often asserted without evidence. Seven questions will tell you what you are actually buying.
1. Which country, and can it be documented?
New Zealand and Australia dominate credible grass-fed supply because pasture feeding is the default rather than a premium programme, and both maintain national traceability schemes. Ask for the country of origin on the Certificate of Analysis, not in an email.
2. Grass-fed, or grass-fed and grain-finished?
"Grass-fed" is not a protected term in every market. Cattle raised on pasture and then grain-finished for the last 90–120 days are still described as grass-fed by some suppliers. Ask specifically whether the animals were grass-fed for life.
3. Freeze-dried or heat-dried?
This is the largest quality variable and the easiest to obscure. Freeze-drying below 45°C preserves heat-sensitive cofactors and enzyme activity. Spray and drum drying are cheaper and faster, and degrade both. Colour is a rough tell — well-made freeze-dried liver powder is a deep reddish brown, not grey or near-black.
4. Defatted or undefatted?
Defatting extends shelf life and improves flow, but strips fat-soluble vitamins — which for liver means much of the vitamin A that buyers are paying for. Undefatted material retains them and demands more careful storage. Neither is wrong; the answer must simply match your product claim.
5. What is the BSE/TSE status?
Any credible supplier provides a BSE/TSE-free statement referencing the country's official risk classification. New Zealand and Australia both hold negligible-risk status. If a supplier cannot produce this document quickly, that is itself informative.
6. Is there a full microbiological panel?
Organ powders are animal-derived and require a complete panel: total plate count, yeast and mould, E. coli, Salmonella and Staphylococcus aureus. Insist on lot-specific results. A generic specification sheet is not a test result.
7. Can the lot be traced to a facility?
Ask for the abattoir or processing facility on the Certificate of Analysis. Suppliers who genuinely control their supply chain can name it. Repackagers usually cannot, because they do not know.
Storage matters after delivery
Freeze-dried organ powders are hygroscopic. Once a container is opened, ambient moisture begins to degrade both colour and nutrient content. Store sealed below 25°C, away from light, and reseal immediately after sampling. Typical shelf life is 24 months unopened.
Our organ powders are New Zealand and Australian sourced, grass-fed for life, freeze-dried below 45°C, and every lot ships with country of origin, facility identification and a full microbiological panel.
