Organ Meats

Overview

Organ meats (offal) are among the most nutrient-dense foods, providing high levels of B12, CoQ10, iron, and other brain-supportive nutrients. Organ meats (heart, liver), oily fish (sardines, mackerel), beef are top sources for CoQ10, and occasional offal consumption is recommended for nutrient density.

Substances

5 substances in this food

Choline

Acetylcholine precursor; methyl donor; phospholipid synthesis for membranes

Coenzyme Q10 (CoQ10)

Electron transport chain cofactor and antioxidant relevant to mitochondrial function

Vitamin A (Retinoids; β-Carotene precursor)

Neurodevelopment; immune regulation; antioxidant via carotenoids

Vitamin B12 (Cobalamin)

Methylation; myelin; mitochondrial odd-chain FA metabolism

Preparation Notes

• Source from grass-fed/pasture-raised when possible

Biological Target Matrix

Biological Target	Substance	Contribution Level	Therapeutic Areas	Mechanism of Action
Gut–Brain Axis & Enteric Nervous System (ENS)	Choline	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base	Choline is metabolised by gut bacteria; some strains (e.g. Lactobacillus) can produce acetylcholine. Microbial choline metabolism (e.g. trimethylamine) shows inter-individual variability and may influence host metabolism and gut–brain signalling.
Inflammation & Oxidative Stress	Choline	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Choline-derived betaine supports homocysteine remethylation; elevated homocysteine is linked to oxidative stress and inflammatory signalling. Phosphatidylcholine supports membrane integrity and cell signalling in immune and redox contexts.
Metabolic & Neuroendocrine Stress (HPA Axis & ANS)	Choline	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base	Choline supports hepatic VLDL assembly and lipid export; methyl donors (choline, betaine) may influence adenosine metabolism and HPA axis activity. Adequate choline status supports metabolic stability and stress physiology.
Methylation & One-Carbon Metabolism	Choline	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease	Precursor to trimethylglycine (TMG/betaine), a dietary methyl donor that helps recycle homocysteine to methionine via an alternative pathway; supports one-carbon metabolism alongside folate, riboflavin, and B12; influences methylation dynamics relevant to MTHFR and COMT activity
Methylation & One-Carbon Metabolism	Vitamin B12 (Cobalamin)	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease	Essential cofactor in remethylation of homocysteine to methionine, which is converted to S-adenosylmethionine (SAMe); works with B6, B2, and folate; contributes meaningfully to homocysteine reduction, especially in combination with omega-3 fatty acids
Mitochondrial Function & Bioenergetics	Choline	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Phosphatidylcholine and other choline-containing phospholipids support mitochondrial membrane integrity and energy metabolism; choline-derived betaine contributes to one-carbon status that can influence mitochondrial resilience
Mitochondrial Function & Bioenergetics	Iron	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Critical for oxygen delivery to the brain via hemoglobin; supports mitochondrial function and energy production
Mitochondrial Function & Bioenergetics	Vitamin B12 (Cobalamin)	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Crucial role in conversion of methylmalonyl-CoA to succinyl-CoA, a key step in mitochondrial energy production; deficiency leads to buildup of methylmalonic acid and odd-chain fatty acids, which are neurotoxic
Neurotransmitter Regulation	Choline	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Essential precursor for acetylcholine synthesis, supporting memory, learning, and neuroplasticity; supports membrane phospholipid biosynthesis (PC) which is critical for membrane fluidity and neurotransmitter receptor function; phospholipid methylation (PLM) alters membrane structure, facilitating faster neuronal recovery and influencing ion channel behavior in gamma oscillations linked to attention and cognition
Neurotransmitter Regulation	Iron	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Essential cofactor for tyrosine hydroxylase, the rate-limiting enzyme in the conversion of tyrosine to dopamine; critical for catecholamine synthesis
Neurotransmitter Regulation	Vitamin B12 (Cobalamin)	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Supports neurotransmitter production through methylation; essential for myelin synthesis
