Heme Iron, Ferritin, and Iron Regulation: Why Liver Is Different

Iron is one of the most misunderstood nutrients in human nutrition. It is essential for life, tightly regulated by the body, and potentially harmful when mismanaged. Public discussion around iron often swings between two extremes: fear of deficiency on one side and fear of overload on the other. Both perspectives miss the most important point. Iron is not meant to be “boosted” indiscriminately or avoided categorically. It is meant to be regulated. Understanding how the body absorbs, stores, and controls iron — and how food-based sources like liver differ from supplements — clarifies why iron-related confusion is so common and...

Vitamin A occupies a rare position in nutrition science. It is unquestionably essential for human health, yet frequently cited as potentially dangerous. This dual reputation has fueled polarized narratives: liver is either portrayed as a nutritional panacea or dismissed as a toxicity risk. Neither framing is accurate. Vitamin A is best understood not as a simple nutrient to be maximized or avoided, but as a biologically regulated signaling molecule. When examined through physiology, epidemiology, and food context, much of the fear surrounding liver consumption dissolves — not because toxicity is impossible, but because it is routinely misunderstood. This article examines...

Powder vs. Capsules: Which Organ Supplement Is Best for You?

Why Format Matters (But Nutrition Comes First) Organ supplements are one of the most powerful ways to bring back the nutrients missing from modern diets. Whether it’s liver, heart, kidney, cartilage, marrow, or the GI tract, organs deliver vitamin A, B12, iron, CoQ10, selenium, peptides, and enzymes that no multivitamin can match. But once you’ve decided to add organs to your routine, the next question is: should you take them as a powder or as capsules? The good news: both formats deliver the same nutrient-dense organs. The difference lies in how you want to use them. Capsules: Convenience and Consistency...

Organ Nutrition & Cognitive Decline: Natural Support for Memory, Focus & Brain Health

Your brain is your body’s command center — governing thought, memory, focus, and emotion. Yet as we age, it’s also one of the first places to show signs of decline. Brain fog, forgetfulness, and reduced focus aren’t just “getting older” — they’re symptoms of nutrient depletion and modern lifestyle stress. The good news? Nature built brain health directly into food. Traditional diets included organ meats — especially brain, liver, and heart — to fuel memory and mental clarity. Today, science confirms what our ancestors knew: organ nutrition provides unique compounds that no synthetic supplement can match. Here’s how organ supplements...
