BRS6(KC2) - Stress-Response Micronutrient & Lipid Sufficiency

(Distinct micronutrient cofactors and membrane lipids; shared-pool status unresolved)

1. Ambition

Maintain adequate micronutrient and membrane-lipid status while keeping their distinct cofactor, oxygen-handling, structural, and signalling roles scientifically separate.

2. Core Nutritional Requirements

3. Evidence Base

Summary

The sources establish that micronutrients perform varied cofactor, energy-metabolism, oxygen-handling, and neuronal roles, while EPA and DHA contribute to membrane structure and signalling (Tardy et al., 2020; Kennedy, 2016; McNamara and Carlson, 2006). They do not identify one interchangeable “stress-response” resource, demonstrate that availability of these nutrients jointly limits HPA-axis and autonomic recovery, or justify combining micronutrient cofactors with long-chain omega-3 membrane lipids as a single nutritional bottleneck.

• Constraint and membership boundary: Biochemical importance does not make magnesium, vitamin C, B vitamins, iron, zinc, EPA, and DHA members of one pool; their cited roles are materially different (Tardy et al., 2020; McNamara and Carlson, 2006).
• Evidence and measurement boundary: The reviews describe nutrient functions and possible deficiency consequences, but they do not measure a shared resource, joint limitation, or common dose-response across the connected mechanisms (Tardy et al., 2020; Kennedy, 2016).
• Biological relevance and provision limitation: Adequacy of each nutrient may matter in its own biological context, yet these sources do not show that supplementation in replete people improves cortisol rhythm, vagal recovery, or autonomic function (Tardy et al., 2020; McNamara and Carlson, 2006).

5. Connected Mechanisms

The connections below remain proposed scope only. The reviewed corpus does not establish that the listed mechanisms draw on one shared micronutrient-and-lipid constraint.

Functional Mechanisms

• BRS6(FM2) - HPA Axis Rhythm & Cortisol Regulation
• BRS6(FM3) - Autonomic Balance & Vagal Recovery Capacity

Primary Mechanisms

• BRS6-FM2-PM4 - Cortisol Rhythm Regulation
• BRS6-FM3-PM6 - Sympathetic Activation & Parasympathetic Recovery
• BRS6-FM3-PM7 - Vagal Tone / HRV Regulation
