GUEST SERIES | Dr. Andy Galpin: Optimal Nutrition & Supplementation for Fitness
Dr. Andy Galpin, a kinesiology professor at California State University, Fullerton, shares insights on optimal nutrition and supplementation for fitness enthusiasts. He delves into the benefits of creatine for muscle and cognitive performance, personalized supplement strategies, and the critical role hydration plays in enhancing physical and mental capabilities. Listeners learn about affordable supplements for recovery, the importance of sleep quality, and effective hydration techniques, ensuring they're well-equipped to boost their performance and well-being.

Creatine: Cheap, potent, everyday fuel
5:16 – 8:12
Creatine monohydrate (3–5 g/day) is foundational — boosts strength, power, recovery, bone health and brain metabolism. Take consistently (weeks) for tissue saturation; loading is optional. Great ROI for most people.
- Muscle & recovery
- Cognitive resilience (sleep deprivation help)
The brain loves creatine as a fuel.

Hydration matters more than you think
21:56 – 26:53
Even 2% bodyweight loss from sweat reduces accuracy, endurance and cognitive performance. Hydration is hormesis — both under- and over-hydration cause problems (hyponatremia from too much plain water).
- Check bodyweight pre/post workout
- Watch urine color & thirst
If you are under hydrated or dehydrated, then there is a clear negative effect on your body.

Galpin Equation — simple intra-workout plan
50:21 – 51:43
Drink about your bodyweight (lb) ÷ 30 in ounces every 15–20 minutes during exercise (≈2 mL/kg every 15–20 min). Sip steadily — smaller boluses reduce GI upset. After exercise, rehydrate with ~125% of fluid lost.
- Example: 200 lb → ~7 oz/15–20 min
Practical and evidence-based.
Caffeine & non-stimulant alternatives →
1:25:21 – 1:29:15
Caffeine (1–3 mg/kg ~30–45 min pre) enhances endurance and alertness — but too much (>5 mg/kg) impairs performance. Train tolerance carefully.
Non-stimulant ergogenics: beetroot/citrulline (NO boosters) and alpha‑GPC (focus) for late sessions when caffeine would harm sleep.
You don't really need to go and blister your brain with caffeine.

Sleep: the ultimate performance tool
2:04:31 – 2:07:41
Sleep underpins recovery, cognition and adaptation. Absolute Rest: diagnose biology, environment, psychology and pathology. Small changes (clean sheets, reduce bedroom CO2, tape mouth if mouth-breathing) yield outsized benefits.
- Treat environment first
- Use targeted interventions only when needed
When to use anti‑inflammatories & recovery stack
2:22:01 – 2:28:46
Follow the fitness–fatigue model: inflammation → proliferation → remodeling. Avoid dampening acute inflammation immediately post-exercise. Useful supplements by phase:
- Inflammation: omega‑3s (2–5 g) or curcumin cautiously
- Proliferation: glutamine (≈20 g/day split)
- Remodeling: prioritize calories & protein (~1 g/lb)
The post-exercise anabolic window is extremely real.
