## 4. Biochemical Synergies & Evidence Strengths
- **Anchor Elements (Highest Evidence Pillars)**: magnesium_threonate, apigenin, l_theanine, glycine, walker_65f_thermal_drop
- **Detected Biological Redundancies**: [object Object], [object Object]
- **Identified Longevity Gaps**: Morning ocular photon circadian anchoring (morning_sunlight) to set the 14-hour nocturnal melatonin timer

### ⚠️ Critical Stack Conflicts & Separation Advice
- **l_theanine vs magnesium_threonate**: In rare sensitive individuals, taking high-dose theanine (>300mg) without sufficient magnesium can induce vivid paradoxical dreaming or early waking.
- **glycine vs heavy_high_protein_dinner**: Large boluses of dietary branched-chain amino acids (BCAAs) compete for large neutral amino acid transporters (LAT1), reducing glycine central nervous system uptake.
