What the AI looks for in Glandular Extract Nutritional Supplements
- Organ type
- Prefer nutrient organs such as liver, heart, kidney and spleen over hormone-producing glands such as thyroid and adrenal. Nutrient organs act like concentrated food. Hormonal glandulars can contain active hormones in unknown amounts.
- Processing
- Freeze-dried, not heat-dried or solvent-extracted. Low-temperature drying preserves heat-sensitive nutrients and is the main quality marker in this category.
- Sourcing
- The label names the species and the grass-fed or pasture origin, for example New Zealand or Argentina. The source animal and the country of origin are the main differences between otherwise identical capsules.
- Ingredient list
- Only the organ and the capsule, with no proprietary blends or added herbs. Proprietary blends hide how much of each organ you actually get.
- Contaminant testing
- The brand publishes or provides third-party testing for heavy metals and microbes. Organ tissue can concentrate contaminants, and supplements are not pre-approved for purity.
Brands that matter
- Ancestral Supplements: The best-known freeze-dried single-organ and mixed-organ capsule range.
- Heart & Soil: Freeze-dried organ blends from regeneratively raised cattle.
- Perfect Supplements: Desiccated organ products, including powders.
What to avoid
- Products marketed to fix the thyroid, adrenals or metabolism.
- Proprietary glandular blends that do not state the amount of each organ.
- Labels with no species or country of origin.
- Taking liver or organ blends alongside high-dose vitamin A supplements.
Questions
Do glandular extracts support the matching organ in my body?
There is no good evidence that eating an animal gland supports your own gland. Organ meats are useful as nutrient sources, not as targeted organ therapy.
