Substances

15 substances in this food

Copper

Cofactor in redox enzymes; dopamine β-hydroxylase; iron metabolism interplay

Histidine

Essential AA; precursor to histamine; roles in enzyme active sites

Iron

Oxygen transport; dopamine synthesis (tyrosine hydroxylase cofactor)

Isoleucine

Essential BCAA; energy metabolism; complements leucine/valine

Leucine

Essential BCAA; mTOR signaling; protein synthesis; cognitive load support

Lysine

Essential AA; limiting in many cereals; complements legumes

Magnesium

Enzymatic cofactor (>300 reactions); neurotransmitters; mitochondria; redox balance

Manganese

Cofactor for MnSOD (SOD2); mitochondrial antioxidant defense

Methionine

Essential AA; precursor to SAMe via methylation cycle

Phenylalanine

Essential AA; precursor to tyrosine → catecholamines

Threonine

Essential AA; structural proteins; mucin production

Tryptophan

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

Valine

Essential BCAA; supports protein balance and neurotransmitter transport competition

Preparation Notes

  • Soak to reduce phytates and improve zinc bioavailability; soaking and sprouting reduces phytates in legumes/grains, improving non-heme iron and zinc bioavailability
  • Part of diverse nut/seed intake; dietary diversity (≥30 plant foods per week) supports microbial richness and resilience
  • Pair with animal proteins or vitamin C for better zinc absorption
  • Supports zinc sufficiency; zinc is critical for neurotransmitter modulation, synaptic plasticity, and antioxidant enzyme function

Biological Target Matrix

Biological TargetSubstanceContribution LevelTherapeutic AreasMechanism of Action
Hormonal ResponseMagnesiumContextual / minor contributorSupports calcium modulation along with vitamin D, taurine, phospholipids, and flavonoids; supports insulin sensitivity, sympathetic arousal, and mitochondrial excitability
InflammationCopperContextual / minor contributorParticipates in redox enzymes and antioxidant networks
InflammationLinoleic Acid (LA, n-6)Contextual / minor contributorEssential omega-6 fatty acid; precursor to arachidonic acid and eicosanoids; excessive n-6:n-3 ratios may skew toward pro-inflammatory eicosanoids
InflammationZincContextual / minor contributorSupports immune signaling; gut barrier integrity disrupted by nutrient deficiencies including zinc
Insulin ResponseMagnesiumContextual / minor contributorSupports insulin sensitivity and glucose metabolism; magnesium deficiency is associated with insulin resistance; supports enzymes involved in glucose metabolism
MethylationMethionineContextual / minor contributorEssential amino acid that forms S-adenosylmethionine (SAMe), the universal methyl donor for neurotransmitter synthesis and membrane phospholipid methylation
MethylationZincContextual / minor contributorDeficiencies 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 SupportIronContextual / minor contributorCritical for oxygen delivery to the brain via hemoglobin; supports mitochondrial function and energy production
Mitochondrial SupportMagnesiumContextual / minor contributorSupports enzymes involved in glycolysis and the Krebs cycle (processes that generate ATP from glucose); binds to ATP and all triphosphates in cells to activate them
Mitochondrial SupportManganeseContextual / minor contributorSupports mitochondrial antioxidant defense through MnSOD activity
Neurochemical BalanceCopperContextual / minor contributorCofactor in dopamine β-hydroxylase, supporting catecholamine synthesis; supports norepinephrine synthesis
Neurochemical BalanceIronContextual / minor contributorEssential cofactor for tyrosine hydroxylase, the rate-limiting enzyme in the conversion of tyrosine to dopamine; critical for catecholamine synthesis
Neurochemical BalanceMagnesiumContextual / minor contributorBroad cofactor for neurotransmitter synthesis and receptor modulation (e.g., NMDA, GABA); functions as an NMDA receptor antagonist and GABA receptor modulator; assists enzymes involved in synthesis of dopamine and serotonin
Neurochemical BalancePhenylalanineContextual / minor contributorEssential amino acid that converts to tyrosine and supports catecholamine synthesis (dopamine, norepinephrine); participates in LAT1 competition at the blood-brain barrier
Neurochemical BalanceTryptophanContextual / minor contributorPrecursor 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
Neurochemical BalanceZincContextual / minor contributorImportant 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
Oxidative StressCopperContextual / minor contributorIncluded in antioxidant enzyme networks; interacts with iron metabolism affecting oxidative stress
Oxidative StressLinoleic Acid (LA, n-6)Contextual / minor contributorEssential fatty acid; balance with omega-3s is emphasized for optimal inflammatory tone
Oxidative StressManganeseContextual / minor contributorEssential cofactor for MnSOD (SOD2), supporting detoxification of superoxide within the mitochondrial matrix
Oxidative StressZincContextual / minor contributorEssential mineral that serves as a cofactor for antioxidant enzymes; works synergistically with other antioxidants; heavy metals are detoxified by metallothionein (MT) metal carrier proteins that must bind with zinc and copper
Stress ResponseMagnesiumContextual / minor contributorHelps manage stress responses; combined with vitamin D reduced behavioral problems; synergy with zinc and omega-3s reported
