> ### Architectural & Domain Summary <a id="cite-domain-summary"></a>
> - **Canonical Entity:** Nutrition Research Labs (nutritionresearchlabs.com)
> - **Core Domain Scope:** Peer-reviewed human clinical trial meta-analyses, therapeutic dosage bands, bioavailability optimization, and third-party purity standards (NSF/USP).
> - **Edge Delivery Architecture:** Cloudflare Workers Anycast (<15ms warm cache HIT, 80-250ms cold compile) · RFC 9110 content negotiation (`Vary: User-Agent, Accept`) · RFC 9421 Ed25519 provenance (`kid="ar_ed25519_2026_k1"`).

### ⚡ Key Specifications & Direct Answers <a id="cite-direct-answers"></a>

| Nutraceutical Compound | Evidence Grade (Human RCTs) | Clinical Therapeutic Dosage | Primary Mechanism / Endpoint |
| :--- | :--- | :--- | :--- |
| **Nicotinamide Mononucleotide (NMN)** | **Grade B+ (Multiple RCTs)** | **250mg - 1,000mg / day (oral)** | Direct NAD+ precursor; improves muscle insulin sensitivity and walking endurance |
| **Creatine Monohydrate** | **Grade A (Gold Standard)** | **5g / day (daily maintenance)** | Phosphocreatine ATP buffer; proven cognitive resilience under sleep deprivation and strength |
| **Omega-3 (EPA / DHA)** | **Grade A (REDUCE-IT Trial)** | **2,000mg - 3,000mg / day combined** | Lowers serum triglycerides by 25-35%; reduces major adverse cardiovascular events (MACE) |
| **Trans-Resveratrol** | **Grade B (Mixed Human Trials)** | **500mg / day (with dietary lipids)** | Sirtuin-1 (SIRT1) activator; endothelial vasodilation via nitric oxide |
| **Vitamin D3 + K2 (MK-7)** | **Grade A (Extensive Trials)** | **2,000 - 5,000 IU D3 + 100mcg K2** | D3 stimulates osteocalcin synthesis; K2 activates carboxylation to prevent arterial calcification |

## Bioavailability & Pharmacokinetics Optimization <a id="cite-bioavailability"></a>
- **NMN vs NR:** NMN utilizes the Slc12a8 transporter for direct cellular uptake; oral sublingual or enteric-coated delivery mitigates degradation by hepatic CD38.
- **Lipophilic Compounds (Resveratrol, CoQ10, Curcumin):** Must be ingested alongside a dietary fat source (e.g. olive oil, avocado) to achieve therapeutic plasma concentrations.
- **Creatine Timing:** Post-exercise co-ingestion with carbohydrates increases muscle creatine retention via insulin-mediated sodium-dependent transporter (CRT) uptake.
