Goji
TL;DR
Deep Yin and Blood tonic from the Shen Nong Ben Cao Jing. Lycium barbarum with LBP (Lycium barbarum polysaccharides) as the primary immune/metabolic fraction. Clinically validated macular protection (AMD RCT: significant MPOD increase at 0.25 eccentricity, p=0.029), metabolic improvements (HDL +10–15 mg/dL, fasting glucose −6–7 mg/dL), and improved neurological well-being. The only functional-food tier TCM Superior Herb — can be consumed as whole fruit daily.
Why it matters for Vitals
Goji is the most directly bioavailable TCM Superior Herb (whole fruit, daily food). The macular pigment optical density (MPOD) data is directly relevant to Vitals visual performance metrics. The HDL and glucose improvements from meta-analysis are clinically meaningful for metabolic coaching. The antioxidant capacity (LBP) provides foundational oxidative stress coverage that complements the more targeted mechanisms of other Superior Herbs.
Key Facts
| Status | OTC; functional food; GRAS |
| Class | TCM Superior Herb — Yin/Blood tonic |
| Primary mechanism | LBP aggressive lipid peroxidation mitigation; zeaxanthin/lutein macular protection; HDL ↑ + fasting glucose ↓ |
| Key benefits | AMD prevention (MPOD ↑), HDL ↑ 10–15 mg/dL, fasting glucose ↓ 6–7 mg/dL, neurological well-being |
| Dosing | 10–30 g/day whole dried berries OR 150–300 mg/day LBP extract; or aqueous decoction |
| Timing | Morning/mid-day with healthy fats (ensures optimal carotenoid/zeaxanthin absorption) |
| Cycling | Continuous — functional food tier; daily dietary use is standard |
| Main risks | STRICTLY contraindicated with warfarin — clinically documented ↑ INR → severe bleeding risk |
| Evidence level | Moderate — AMD RCT (n=27, 90 days); meta-analysis (5 RCTs, ~548 participants) |
Mechanism Summary
Macular protection: Extraordinarily high zeaxanthin and lutein content → absorbs oxidative UV/blue light within retina → protects ophthalmic structures. Goji is the richest common dietary source of zeaxanthin.
AMD RCT (n=27, 90 days, middle-aged 45–65):
- Significant ↑ macular pigment optical density (MPOD) at 0.25 eccentricity — p=0.029
- ↑ skin carotenoids (p=0.006)
- Delayed AMD progression
Metabolic improvements:
- HDL: +10–15 mg/dL (multiple RCTs)
- Fasting glucose: −6–7 mg/dL (multiple RCTs)
- No body weight change
Systemic antioxidant: LBP aggressively mitigates lipid peroxidation; 14-day RCT: improved subjective neurological performance + general well-being.
Drug Interactions
| Drug | Interaction |
|---|---|
| Warfarin | Clinically documented ↑ INR — STRICTLY contraindicated. Severe bleeding risk. |
Unique Contribution
The only “functional food” tier TCM Superior Herb — can be consumed as whole fruit daily. This makes Goji the most accessible and sustainable daily supplement in the Superior Herb matrix.
