What are the best post-workout recovery supplements in New Zealand?
For New Zealanders training hard — gym, CrossFit, golf, running, rugby, or simply weekend tramping — the three most evidence-backed recovery supplements are Magnesium Glycinate (muscle relaxation + deep sleep, the bigger lever for recovery), Green Lipped Mussel (joint and connective tissue anti-inflammatory), and L-Carnitine (mitochondrial recovery and lactate clearance).
The three pillars of evidence-based recovery
| Pillar | Mechanism | WIIP source |
|---|---|---|
| Sleep quality + muscle relaxation | Magnesium activates parasympathetic tone, glycine enhances deep sleep. Most muscle repair happens during slow-wave sleep. | Muscle Relax+ (400mg elemental Mg) |
| Joint and connective tissue inflammation | Green Lipped Mussel long-chain omega-3 + L-Carnitine reduces post-exercise CK and DOMS. | Joint Comfort+ (1,000mg GLM + 200mg L-Carnitine + 800 IU D3) |
| Cellular energy (NAD+ rebuild) | NMN converts to NAD+, which mitochondria need for ATP generation. Hard training depletes NAD+. | NMN Boost+ (500mg NMN) |
Clinical evidence
- Cordingley et al. 2019 Green Lipped Mussel oil reduced CK, ECC-induced muscle damage, and DOMS in a 28-day trial. PMID 31269630.
- Reno et al. 2020 magnesium supplementation reduced muscle soreness and improved recovery in trained athletes.
- Bannai 2012 glycine improves sleep quality, the foundation of recovery.
- Conze et al. 2017 L-Carnitine reduced markers of muscle damage post-exercise in older adults.
NZ practitioner protocol (general healthy adults)
- Daily morning: Joint Comfort+ 2 caps with breakfast (joint and inflammation baseline).
- Daily evening (1-2 hrs before bed): Muscle Relax+ 2 caps (sleep + muscle relaxation).
- Daily morning (optional): NMN Boost+ 2 caps if training 5+ times per week or aged 40+.
- WIIP Bundle = all three above with 10% off, the simplest stack for active people.
What this protocol replaces
- Generic BCAAs — redundant if you eat enough protein (no recovery benefit in fed athletes).
- Caffeine + creatine "pre-workouts" — these are pre-workout, not recovery.
- Cheap fish oil — many imported brands fail label-claim testing (low EPA/DHA, rancidity).
