For most of human history, organ meats were the most prized part of the animal — the parts reserved for the strongest, the most honoured, the most revered. Modern food culture discarded them. The nutritional science is bringing them back.
Heart — Cellular Energy
Heart is one of the richest dietary sources of CoQ10 — a compound essential for mitochondrial energy production. Your mitochondria are the power generators inside every cell, and CoQ10 is the fuel that keeps them running at full capacity.
Heart is also exceptionally high in protein, haem iron, zinc, and B vitamins — making it one of the most complete single foods available for athletic performance and recovery. Gram for gram, it outperforms muscle meat on almost every nutritional metric.
Liver — Nature's Multivitamin
Liver is the single most nutrient-dense food on earth. It contains more B12, vitamin A, iron, and choline per gram than any other whole food — and in forms your body absorbs immediately and efficiently.
Vitamin A for immune function and cellular repair. B12 for nerve function and energy metabolism. Haem iron at up to 30% bioavailability. Choline for neurotransmitter synthesis. No supplement stack comes close to what a small amount of high-quality liver delivers.
Kidney — The Mineral Profile
Kidney is exceptionally rich in selenium — a trace mineral critical for thyroid function, antioxidant defence, and immune health. It also provides zinc, B12, and iron in highly bioavailable forms.
Thyroid health underpins metabolism, energy regulation, and hormonal balance. Selenium is one of the most commonly under-consumed minerals in the modern diet. Kidney is one of the easiest ways to address that.
Spleen — The Overlooked Powerhouse
Spleen is extraordinarily rich in haem iron — making it one of the most effective whole food solutions for iron deficiency and the fatigue, brain fog, and poor recovery that accompany it. It also provides unique peptides associated with immune regulation and red blood cell production.
Most people have never intentionally eaten spleen. Every Wildfang bar contains it — freeze-dried, flavourless, and delivering its full nutritional profile intact.
Why Wildfang Uses Grass-Fed Tasmanian Organs
The nutritional profile of organ meats varies significantly based on how the animal was raised. Grass-fed, pasture-raised animals produce organs with higher concentrations of fat-soluble vitamins, CoQ10, and omega-3 fatty acids than grain-fed equivalents.
Wildfang sources its organ complex exclusively from grass-fed Tasmanian farms — freeze-dried to preserve every nutrient, ground into a fine powder, and completely undetectable in flavour. All the ancestral nutrition. None of the barrier to eating it.
The Bottom Line
Our ancestors didn't eat organ meats because they had no other option. They ate them first because they instinctively understood they were the most valuable part of the animal. Modern nutritional science has confirmed what that instinct already knew.
