    Animal-Based Micronutrients: Adequacy Wins, Toxicity Ceilings, and Electrolytes

    Meat covers B12/zinc/heme iron well; strict carnivore risks C/Mg/K/iodine gaps. Organs fix gaps and create retinol/iron/copper excess risk. Fruit upgrades C.

    Paul Saladino Human Evidence: Surveys, Trials Gap, and What Lennerz Actually Is

    Human evidence for carnivore/animal-based is mostly self-selected surveys and anecdotes—not hard-outcome RCTs. Never call Lennerz a Harvard clinical trial.
