What happened in this episode?
Thomas DeLauer describes his experiment eating roughly one ounce of liver weekly and frames it as a way to support mitochondrial energy, iron status, eyesight and methylation-related nutrient needs. He contrasts chicken liver and beef liver, claiming chicken liver has higher CoQ10 per 100g while beef liver is richer in retinol and certain B vitamins. He cites a CoQ10 supplementation trial in heart-failure patients and argues that obtaining CoQ10 from liver is more effective because it comes with “co-actors” such as iron, B vitamins and copper, while also recommending CoQ10 supplementation in some cases (including for people on statins, which he says deplete CoQ10).
DeLauer also presents liver as a superior iron source due to haem iron absorption and suggests some people may have cellular-level iron issues even with normal blood tests, pointing to symptoms such as cold hands/feet, brain fog and getting winded easily. On safety, he warns against eating liver daily, claiming excessive retinol can compete with vitamin D at a shared receptor and reduce calcium absorption, and advises taking vitamin D on non-liver days.
He further argues that synthetic folic acid may not convert well in people with MTHFR variants and claims unmetabolised folic acid can interfere with folate uptake, while liver provides active folate alongside B12. The episode includes an affiliate-style promotion for a C15 supplement (Fatty15) with a discount link, plus food-prep suggestions (light cooking, pâté, mixing into mince) and a closing pointer to a separate oysters video.
