Enzymatic activity does not survive heat.
Enzymes are proteins. Their function depends on their three-dimensional structure. Above approximately 40-45°C, enzymatic proteins begin to denature - their structure unfolds and their biological activity ceases. Lipase, protease, amylase, and the full spectrum of organ-specific enzymes present in pancreatic and liver tissue are completely inactivated by heat processing. A heat-dried organ supplement delivers the label claim. It does not deliver the enzymatic activity. 10
Peptide integrity is equally temperature-sensitive. Thymic peptides - thymosin beta-4, thymulin, thymopoietin - are small signalling molecules whose biological activity depends on precise structural conformation. Heat exposure compromises this conformation. Freeze-drying at sub-zero temperatures maintains the complete three-dimensional structure of every peptide, enzyme, and bioactive compound from harvest to capsule. 11
Freeze-drying achieves stability without preservatives.
Freeze-drying reduces the water activity of organ tissue to below 0.3 - the threshold below which enzymatic degradation, oxidative damage, and microbial activity cease entirely. This is not dehydration. It is sublimation - ice converted directly to vapour under vacuum, leaving the biological matrix structurally intact with moisture removed. 12
The result is a stable, shelf-stable product that requires no preservatives, no heat stabilisers, and no anti-caking agents. Nothing is added. The organ tissue - with its complete bioactive matrix intact - is simply encapsulated. This is the only processing method consistent with delivering whole organ nutrition as nature designed it.
The label and the bioactivity are not the same thing.
Two liver supplements can show identical label claims - 500mg beef liver per serving - while delivering radically different biological value. One is heat-dried. One is freeze-dried. The retinol content may be comparable. The CoQ10 may be comparable. The enzymatic activity, the peptide integrity, the full spectrum of heat-labile bioactives - these are not comparable. 13
This distinction is not disclosed on supplement labels. It should be. Mykora freeze-dries every organ at sub-zero temperatures. We do this because it is the only method that preserves the complete biological argument for organ nutrition.
