Lamb

Overview

Lamb provides creatine, heme iron, and complete high-quality protein, supporting ATP recycling and neurotransmitter synthesis. Creatine: Supports ATP recycling in neurons; enhances working memory and cognitive processing speed; food sources include beef, lamb, pork, salmon, tuna, cod, scallops. Iron (heme & non-heme): Oxygen delivery to brain, dopamine synthesis; food sources include liver, beef, lamb, poultry, fish. Heme iron is 2-3× more bioavailable than non-heme iron.

Substances

4 substances in this food

Iron

Oxygen transport; dopamine synthesis (tyrosine hydroxylase cofactor)

Tryptophan

Serotonin/melatonin precursor; NAD+ pathway substrate; LAT1 transport dynamics

Tyrosine

Dopamine and norepinephrine precursor; LAT1 competition with LNAAs

Zinc

Cofactor in neurotransmission and antioxidant enzymes; dopamine modulation

Preparation Notes

• Choose grass-fed when possible for better fatty acid profile
• Gentle cooking preserves nutrients and prevents formation of advanced glycation end products (AGEs)
• Important for creatine and heme iron intake
• Part of diverse protein strategy
• Supports neurotransmitter synthesis through tryptophan and tyrosine content

Biological Target Matrix

Biological Target	Substance	Contribution Level	Therapeutic Areas	Mechanism of Action
Inflammation & Oxidative Stress	Zinc	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Supports immune signaling; gut barrier integrity disrupted by nutrient deficiencies including zinc
Methylation & One-Carbon Metabolism	Zinc	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease	Deficiencies in vitamins and minerals essential for methylation, such as folate, vitamin B12, and zinc, are correlated to ADHD symptoms; supplementing these micronutrients has shown potential in supporting methylation and reducing symptom severity
Mitochondrial Function & Bioenergetics	Creatine	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Supports ATP recycling via phosphocreatine system; buffers high-energy demand in neurons; enhances mitochondrial energy buffering
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
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	Tryptophan	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Precursor for serotonin and melatonin; brain entry competes at LAT1 with other large neutral amino acids (LNAAs); carbohydrate-rich, low-protein meals raise the plasma tryptophan:LNAA ratio because insulin pushes competing LNAAs out to muscles; can feed NAD+ synthesis via the kynurenine pathway
Neurotransmitter Regulation	Tyrosine	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Catecholamine precursor (dopamine, norepinephrine); brain transport via LAT1 competes with other LNAAs; iron is an essential cofactor for tyrosine hydroxylase, the rate-limiting enzyme in conversion of tyrosine to dopamine; cofactors include iron, B6, folate, omega-3s, and BH₄ (tetrahydrobiopterin) to support rate-limiting steps in catecholamine synthesis
Neurotransmitter Regulation	Zinc	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Important for DNA synthesis, cell division, and neurotransmitter regulation, particularly in modulating dopamine—a key neurotransmitter implicated in ADHD; acts as an allosteric modulator of the GABA receptor; supports glutamate regulation
