Dr. Andy Galpin: The Optimal Diet, Supplement, & Recovery Protocol for Peak Performance

Galpin's clinic spans athletes from 115 lbs to 350 lbs — the flat-5 g convention breaks down completely at the extremes. He notes Darren Candow has run subjects at 20 g/day for years without safety signals. He also references cognitive benefits at higher doses as an additional rationale for going above 5 g. Unlike beta-alanine, creatine does not require an acute pre-workout dose — saturation is what matters, so timing is flexible.

Galpin notes objective improvements in multiple sleep metrics with magnesium supplementation, regardless of form. He has not seen large differences between bisglycinate, citrate, and threonate in practice. The sleep benefit appears robust and is measurable on clinical-grade sleep equipment his clinic uses. He also notes the bone-reservoir angle: bones are depleted of magnesium as a reservoir for the rest of the body, such that plasma magnesium stays 'normal' even when skeletal stores are exhausted — making standard blood tests misleading. Athletes eating meat-heavy, vegetable-light diets tend to be the most deficient in his practice.

Patrick introduced the McIlroy disuse-atrophy data: omega-3 pre-loading (4–5 weeks to achieve membrane saturation) cut disuse atrophy by roughly 50% in a cast-immobilization RCT, independent of anti-inflammatory effects — implying a direct anabolic sensitization mechanism where omega-3-enriched cell membranes respond better to amino acid signaling, mimicking some of the exercise stimulus even during disuse. Galpin finds this plausible and consistent with the 'healthier cell membrane does more things' framework. He notes most of his athletes are not already at high omega-3 indices, making the argument for supplementation even more practical.

Galpin describes deliberately giving un-warned friends beta-alanine as a joke — the tingling kicks in within minutes at higher doses and feels like rolling in grass. He used to tell people timing mattered but now splits the dose throughout the day instead. The paresthesia desensitizes with continued use. He notes beta-alanine is chronically effective — you cannot blind subjects in trials, but performance improvements in time-to-failure and total work done are well-replicated across decades of research. It is one of the few non-stimulant ergogenic aids with a clearly understood mechanism.

Galpin's team uses beetroot extract as a caffeine-free afternoon energizer — specifically for clients who are training at 4 PM and start flagging motivationally at 2 PM. They give them a beetroot hit at 2 PM to restore drive without the evening caffeine burden that would compress sleep. He also notes the under-appreciated cognitive component: nitric oxide improves cerebral blood flow, so the same dose that gives a gym pump also sharpens focus. He has not personally seen the argument for citrulline overcome the 'too stimulating' reports from some users, and prefers the slightly softer but still strong beetroot profile.

Patrick shared her personal protocol: she takes ~5.6 g/day prophylactically and escalates to 20–25 g at first sign of illness. She reports going from frequently sick to near-zero upper respiratory infections. She also gives her son ~5 g/day, reporting similarly dramatic reduction in illness frequency without his knowledge — ruling out placebo. Galpin's concussion/TBI review paper (with Tommy Wood and Federica Kasparek) cites glutamine as a key nutrient across the prevention and post-injury spectrum. Galpin's clinic uses 20 g/day (split) as the standard protocol for gut-issue clients, and notes the T-cell connection Patrick describes is mechanistically coherent: activated T cells use glutamine as alpha-ketoglutarate for mitochondrial energy.

Galpin notes rhodiola has a fraction of the research base of beetroot juice ('a pebble versus a mountain') but the available data on muscular endurance is compelling and the safety profile is excellent. He has used it for 10+ years. He finds it interesting that it can be blinded in studies — unlike caffeine, beta-alanine, or beetroot, subjects cannot tell they took it. The HRV reduction-per-bout effect is the clearest signal in his own athlete data: the same training stimulus causes less autonomic strain when rhodiola is in the stack. This is consistent with adaptogen framing — it is not blocking adaptation (unlike problematic antioxidants), but it may be making the adaptation process less energetically expensive.

Galpin changed his position on collagen after years of skepticism. The study that convinced him was a decade-old animal study showing radiolabeled hydrolyzed collagen peptides appearing intact at tendons — suggesting selective connective-tissue targeting. He now recommends it prophylactically for soft-tissue injury-prone athletes. He frames the decision in typical risk-benefit terms: no known downside physiologically, potential multi-system benefit (tendons, skin, joints), some reasonable evidence. The 30–60 min timing comes from Keith Barr's research showing that pre-exercise collagen ingestion coincides with exercise-induced increase in tendon blood flow.

Galpin describes his research-lab experience with oral sodium bicarbonate as memorable: subjects were in such GI distress that they could not stay far from the bathroom. The PR Lotion solves this entirely. He positions sodium bicarbonate (oral or topical) and beta-alanine as two different approaches to the same problem — muscle acidosis — with beta-alanine being the chronic intracellular approach and sodium bicarbonate being the acute extracellular approach. Both are validated; choice depends on GI tolerance and preference.

Galpin's personal wind-down signal is reading obscure sports blogs — something clearly non-work-related that gives his brain permission to stop processing. He uses hunting and outdoor videos. His wife's signal is completely different. The point is individual — whatever cognitive activity signals 'this is your time, stop being productive.' He connects the 'wake up at 2–3 AM and cannot get back to sleep' pattern directly to insufficient wind-down index the night before. He also advocates waking at most once to urinate (ideally zero) — more than once per night indicates either too much fluid pre-bed or a ventilation/nasal issue that is disrupting sleep maintenance.

Galpin distinguishes between soreness from a training error and soreness from a well-structured progressive program. For training errors, no supplement can fix it — the input (training program) was wrong. For appropriate soreness from good programming, blood flow acceleration works dramatically. He lists six modalities that all operate through the same fundamental mechanism — blood circulation — and says pick your price point: free (light jog), cheap (bath), mid-range (compression boots), premium (Firefly). The fascial version of pain (IT band, fascia-specific soreness) has a slightly different intervention — horizontal tissue-gliding (voodoo floss, cupping) rather than vertical compression — because fascial pain is a glide-and-slide restriction problem, not a blood-flow problem.

Subjects trained in the morning, fasted, then waited at least an hour post-training before eating. Despite that, muscle mass and strength gains were not significantly different from the control group — the bodies adapted. The signal that something was wrong was performance decline in leg volume work toward the end of the 8-week block and higher subjective fatigue scores over time. Galpin suspects muscle glycogen was slowly leaking down across the study. He notes that if TRE subjects had shifted their fasting window to evenings instead of mornings, both the fatigue and GI distress problems (600 g carbs in 8 h was 'destroying GI') would likely have been attenuated.

Galpin describes the peer-review response: 'Everybody knew it was going to happen — you're just like, okay, how we're like, well, I don't know. We don't have this.' The team offered several plausible mechanisms: choline's role in cell membrane integrity, omega-3s improving amino-acid transporter function, vitamin D's known anabolic signaling. None were tested in the study. The finding is consistent with the broader evidence that whole food always outperforms isolated macronutrient fractions when the comparison is direct. Galpin's clinic defaults to whole-food protein for all clients.

Galpin's clinic does not use CWI primarily for muscle-growth athletes. They use it for stress inoculation, nervous system resilience, and breathing mechanics training. For pure recovery from soreness (not adaptation), CWI does work — water immersion beats cryotherapy, and cryotherapy beats cold showers. He personally has a freezer-chest cold plunge at home but does not prescribe it daily. He also notes that CWI can worsen sleep and raise allostatic load in people already under chronic stress — meaning the cold is a stressor, and if the bucket is already overflowing, adding CWI makes it worse.

Galpin's team used multi-metric wearables during the COVID-19 era with NFL and NBA athletes. An algorithm combining respiratory rate, body temperature, and a few other variables flagged athletes as COVID-positive days before they had any symptoms — with high accuracy, even at wrist-level accuracy. He now considers respiratory rate the leading edge of his recovery monitoring stack. He notes that true overtraining (weeks-to-months to recover) is far rarer than people think; the real hazard zone for most hard-chargers is non-functional overreaching — where performance declines and does not bounce back after a few days off.

Galpin's California home regularly hit 2,200 ppm by 7 PM with four humans and two dogs in a closed 2,400-square-foot house. His solution was starting the ventilation process hours earlier — opening doors and windows in the afternoon to let CO2 clear before bedtime. He recommends CO2 monitors as standard equipment sent to all his athletes. He pairs this with nasal patency (allergens, gravity, and mouth-breathing as secondary compounders) and recommends Flonase or nasal dilator strips for people whose noses block up only at night — a gravity and allergen issue, not a chronic one.

Some athletes have a natural standard deviation of 5 ms; others fluctuate 20 ms normally. Both can be healthy. The width of the range is itself diagnostic — a very narrow range may indicate nervous system rigidity while a very wide range may indicate instability. Galpin's team has pulled HRV tracking from clients who become anxious about daily variation, because the psychological cost outweighs the physiological data value. He also notes that wearable companies change their HRV algorithms, causing apparent score shifts that have nothing to do with the athlete's physiology.
