BRS1(FM3) - Cholinergic Function (Attention & Cognitive Precision)
1. Definition
Provision of dietary choline and cholinergic support relevant to attention, working memory, and cognitive precision.
2. Intervention Breakdown
Food-State Dominant
3. Functional Role
↑ choline availability; ↑ acetylcholine synthesis support; ↑ cholinergic signalling context
4. Mechanistic Basis (Implementation of PMs)
Dietary choline and phospholipid context for acetylcholine synthesis support.
PM3 governs Acetylcholine Synthesis Support.
Together, these PMs operationalise BRS1(FM3) as coordinated cholinergic substrate support.
5. Underlying Mechanisms and Requirements
5.1 Cofactors and Substrates
| PM | Cofactors | KC substrates |
|---|---|---|
| BRS1(PM3) | B5, B12, folate | choline, dietary protein, tryptophan, tyrosine, LNAAs (KC1) |
5.2 PMs (Primary Mechanisms)
5.3 KCs (Key Constraints)
5.4 Cross-BRS Links
- None listed
6. Dietary Levers
Diet
- Choline ← eggs, liver, beef
- Phosphatidylcholine ← eggs
7. Lifestyle Levers
Lifestyle
- Meal timing and protein–carbohydrate composition may modulate neurotransmitter bias where relevant to this FM.
- Sleep regularity and stress-load management may influence downstream neurotransmitter tone (broader modifiers).
8. Scoreable Inputs & Modulation Signals
These inputs are used within the BRAIN Diet ontology to generate evidence-constrained estimates of plausible BRS1 support. They are not direct measures of clinical efficacy.
