What the AI looks for in Liver Extract Nutritional Supplements
- Vitamin A awareness
- Check that the vitamin A content per serving is stated, and keep total preformed vitamin A from all sources within the adult upper limit. Liver is the most concentrated food source of preformed vitamin A, and chronic excess is toxic.
- Drying method
- Freeze-dried, not heat-processed or defatted with solvents. Freeze-drying best preserves the nutrients you are buying liver for.
- Source
- The species and grass-fed origin are stated on the label. This is the main quality difference between single-ingredient liver capsules.
- Contaminant testing
- Third-party heavy-metal testing is available from the brand. The liver filters toxins, so purity testing matters more here than for muscle meat.
Brands that matter
- Ancestral Supplements: The best-known freeze-dried grass-fed liver capsule.
- Perfect Supplements: Desiccated liver in both powder and capsule form.
- Heart & Soil: Also sells liver-focused organ capsules.
What to avoid
- Liver capsules bundled with proprietary herbal "detox" blends.
- Products that do not state the source animal or country.
- Stacking liver capsules with a multivitamin that contains high retinol.
Questions
Does liver supplement support my own liver?
No. It is a nutrient source rich in vitamin B12, vitamin A and iron, not a liver-health treatment.
