Clams

Overview

Clams provide very high levels of taurine (raw clams: ~240–520 mg/100 g) and vitamin B12, supporting neurotransmission, methylation pathways, and cardiovascular health. Among shellfish, clams and mussels are particularly rich in taurine, which regulates calcium signaling, antioxidant defense, and neurotransmission Wójcik et al. 2009. Vitamin B12 from clams is essential for methylation, homocysteine recycling, and neurotransmitter synthesis. Clams also supply iron, zinc, and selenium.

Substances

5 substances in this food

Iron

Oxygen transport; dopamine synthesis (tyrosine hydroxylase cofactor)

Taurine

Osmoregulator; GABA modulation; mitochondrial membrane stabilizer; anti-inflammatory

Tryptophan

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

Tyrosine

Dopamine and norepinephrine precursor; LAT1 competition with LNAAs

Vitamin B12 (Cobalamin)

Methylation; myelin; mitochondrial odd-chain FA metabolism

Preparation Notes

• Best prepared with gentle cooking to preserve nutrients
• Sustainable seafood option
• Important for taurine and B12 intake; B12 is essential for methylation, homocysteine recycling, and neurotransmitter synthesis
• 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
Metabolic & Neuroendocrine Stress (HPA Axis & ANS)	Taurine	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base	Buffers HPA axis dysregulation; reduces cortisol; supports stress resilience
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	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	Taurine	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Protects mitochondrial function under oxidative stress; stabilizes mitochondrial membranes; supports ATP 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	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	Taurine	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Modulates calcium handling; influences GABAergic tone; supports neurotransmitter balance
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	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
