Why Organ Supplements Are Not Multivitamins: A Biological Systems Perspective
Posted by PrimalRx Team on
Organ supplements are often described as “natural multivitamins.” The comparison is understandable. Both aim to provide micronutrients. Both appear in capsule form. Both are used to address gaps in modern diets. But biologically, the comparison collapses almost immediately. Multivitamins and organ supplements are built on entirely different models of human nutrition. One is a product of early deficiency science and industrial standardization. The other reflects how nutrients have always been delivered to human physiology: as integrated biological systems, not isolated inputs. Understanding this difference requires moving beyond ingredient lists and into how the body actually absorbs, regulates, and uses nutrients....

Heme Iron, Ferritin, and Iron Regulation: Why Liver Is Different
Posted by PrimalRx Team on
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 Toxicity vs Deficiency: Where Liver Actually Fits in the Evidence
Posted by PrimalRx Team on
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...

Organs vs Bone Broth, Collagen, and Fish Oil: What’s Really Best?
Posted by PrimalRx Team on
Introduction: The Great Supplement Showdown If you’ve spent time in the health and wellness world, chances are you’ve tried (or at least considered) bone broth, collagen powders, or fish oil. These supplements dominate shelves and social media — each promising stronger joints, better skin, or reduced inflammation. But if you’ve cycled through all of them and still felt something was missing, you’re not alone. The truth is, while each of these supplements offers benefits, they often provide only pieces of the nutritional puzzle. For complete, bioavailable nutrition, nothing compares to organ supplements, which deliver vitamins, minerals, lipids, and peptides together...
