Dark Chocolate
Overview
Dark chocolate (70%+ cocoa) provides flavanols and polyphenols that support cognitive function, though heavy metal content increases with cocoa percentage. Polyphenol sources include berries, green tea catechins, cocoa flavanols, cranberries, and pomegranate. While dark chocolate has high antioxidants, heavy-metals increase with cocoa content; adding milk content raises available Ca/Zn to reduce intestinal absorption of cadmium and lead.

Substances
Preparation Notes
- Choose 70%+ cocoa for higher flavanol content
- Consider higher-milk/lower-cocoa options to reduce heavy metal absorption
- Select low-Cd/Pb origins with strong post-harvest controls
- Pair with calcium/zinc sources to reduce metal absorption
Biological Target Matrix
| Biological Target | Substance | Contribution Level | Therapeutic Areas | Mechanism of Action |
|---|---|---|---|---|
| Inflammation & Oxidative Stress | Zinc | Contextual / minor contributor | Supports immune signaling; gut barrier integrity disrupted by nutrient deficiencies including zinc | |
| Metabolic & Neuroendocrine Stress (HPA Axis & ANS) | Magnesium | Contextual / minor contributor | Helps manage stress responses; combined with vitamin D reduced behavioral problems; synergy with zinc and omega-3s reported | |
| Methylation & One-Carbon Metabolism | Zinc | Contextual / minor contributor | 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 | Iron | Contextual / minor contributor | Critical for oxygen delivery to the brain via hemoglobin; supports mitochondrial function and energy production | |
| Mitochondrial Function & Bioenergetics | Magnesium | Contextual / minor contributor | 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 | |
| Neurotransmitter Regulation | Iron | Contextual / minor contributor | Essential cofactor for tyrosine hydroxylase, the rate-limiting enzyme in the conversion of tyrosine to dopamine; critical for catecholamine synthesis | |
| Neurotransmitter Regulation | Magnesium | Contextual / minor contributor | 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 | |
| Neurotransmitter Regulation | Zinc | Contextual / minor contributor | 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 |
