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 Target | Substance | Therapeutic Areas | Mechanism of Action |
|---|---|---|---|
| Hormonal Response | Magnesium | Supports calcium modulation along with vitamin D, taurine, phospholipids, and flavonoids; supports insulin sensitivity, sympathetic arousal, and mitochondrial excitability | |
| Inflammation | Copper | Participates in redox enzymes and antioxidant networks | |
| Inflammation | Linoleic Acid (LA, n-6) | Essential omega-6 fatty acid; precursor to arachidonic acid and eicosanoids; excessive n-6:n-3 ratios may skew toward pro-inflammatory eicosanoids | |
| Inflammation | Zinc | Supports immune signaling; gut barrier integrity disrupted by nutrient deficiencies including zinc | |
| Insulin Response | Magnesium | Supports insulin sensitivity and glucose metabolism; magnesium deficiency is associated with insulin resistance; supports enzymes involved in glucose metabolism | |
| Methylation | Methionine | Essential amino acid that forms S-adenosylmethionine (SAMe), the universal methyl donor for neurotransmitter synthesis and membrane phospholipid methylation | |
| Methylation | Zinc | 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 Support | Iron | Critical for oxygen delivery to the brain via hemoglobin; supports mitochondrial function and energy production | |
| Mitochondrial Support | Magnesium | Supports 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 Support | Manganese | Supports mitochondrial antioxidant defense through MnSOD activity | |
| Neurochemical Balance | Copper | Cofactor in dopamine β-hydroxylase, supporting catecholamine synthesis; supports norepinephrine synthesis | |
| Neurochemical Balance | Iron | Essential cofactor for tyrosine hydroxylase, the rate-limiting enzyme in the conversion of tyrosine to dopamine; critical for catecholamine synthesis | |
| Neurochemical Balance | Magnesium | Broad 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 Balance | Phenylalanine | Essential amino acid that converts to tyrosine and supports catecholamine synthesis (dopamine, norepinephrine); participates in LAT1 competition at the blood-brain barrier | |
| Neurochemical Balance | Tryptophan | 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 | |
| Neurochemical Balance | Zinc | 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 | |
| Oxidative Stress | Copper | Included in antioxidant enzyme networks; interacts with iron metabolism affecting oxidative stress | |
| Oxidative Stress | Linoleic Acid (LA, n-6) | Essential fatty acid; balance with omega-3s is emphasized for optimal inflammatory tone | |
| Oxidative Stress | Manganese | Essential cofactor for MnSOD (SOD2), supporting detoxification of superoxide within the mitochondrial matrix | |
| Oxidative Stress | Zinc | Essential 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 Response | Magnesium | Helps manage stress responses; combined with vitamin D reduced behavioral problems; synergy with zinc and omega-3s reported |
