Recovery & Biohacking Stack
Stack the recovery tech and supplements that move the needle, layered the way Greenfield actually runs his day.
Greenfield is the archetypal biohacker: he layers light, heat, cold and PEMF on top of training, sleep and a low-carb, nutrient-dense diet, with a targeted supplement stack. His philosophy is to optimise what you are already doing. The devices are big-ticket; the foundations (sleep, contrast therapy, a few supplements) carry most of the benefit.
Why it works▼
Full-body red light therapy
Used for mitochondrial support, skin and recovery; he layers it onto things he is already doing.
Hot-cold contrast therapy
His single most-used recovery tool: vascular training plus a stress-resilience hit.
Refuel: recovery shake and electrolytes
Replaces what training burns and kick-starts repair.
Core supplement foundation
The best-evidenced supplements he keeps coming back to.
Down-regulate for sleep
Shifts you to the parasympathetic state that lets deep sleep happen.
PEMF therapy
Used for cellular recovery and sleep onset. Evidence is emerging, not settled.
Greens and antioxidant support
A convenient micronutrient backstop, not a replacement for vegetables. Evidence varies by ingredient.
Fasted morning training and a low-carb, nutrient-dense diet
The unglamorous base under all the gear: movement, real food, metabolic flexibility.
High-end therapies
Listed to describe his approach. We do not sell or dose prescription or clinic-only interventions.
- Hard trainers and high-stress lifestyles
- People plateaued who want to dial in recovery
- Gadget-inclined optimisers (with the budget for devices)
- Anyone building a home recovery setup
- Many devices have limited or emerging evidence; nail the basics (sleep, training, diet, cold/heat) before buying gear
- Cold and heat: cardiac conditions or pregnancy, clear it with a doctor
- Peptides, hyperbaric oxygen and similar are prescription or clinic-only; we do not sell or dose them
- Supplement evidence varies (for example, oral glutathione absorption is debated); consult a doctor or pharmacist
- Note: some items he discusses, such as nicotine, are addictive and are intentionally excluded here
