Ranked by how much each one actually moves the needle — our SAC Efficacy Score™. Supplements, protocols and gear compete in ONE ranking.
Creatine Monohydrate
Supplementmore power for repeated high-intensity efforts (less for steady-state)
7.6/10SAC Efficacy Score™- Effect size45%Moderate
- Evidence40%Very strong
- Reliability15%Works for most
Why these numbers?
Effect size: Creatine adds power to repeated high-intensity efforts — surges, hills, sprints — and improves body composition (Branch 2003); steady-state endurance barely moves and a kilogram of water weight can cost a runner. 6.0/10.
Evidence: The best-studied sports supplement; ISSN position stand on safety and efficacy (Kreider 2017): 9.0/10.
Reliability: Works in most people; the water weight is the trade-off for pure endurance athletes. 8.4/10.
Power for the surges, not the cruise.

Creatine Monohydrate · 7.6Beetroot (Dietary Nitrate)
Supplementimproved time-trial performance + time-to-exhaustion via the nitrate to NO pathway (Lansley 2011)
⚑ depends on actual nitrate dose, which most labels do not disclose6.9/10SAC Efficacy Score™- Effect size45%Moderate
- Evidence40%Strong
- Reliability15%Works for many
Why these numbers?
Effect size: 500 ml of beetroot juice improved 4-km and 16-km cycling time-trial performance by ~2.8% via the nitrate-to-nitric-oxide pathway (Lansley 2011); a 2017 meta-analysis confirms a small but real endurance benefit (McMahon 2017). 6.0/10.
Evidence: Dozens of controlled trials pooled, effect consistent in recreational athletes: 8.0/10.
Reliability: Recreational and sub-elite athletes respond; highly trained endurance athletes gain less, and mouthwash kills the effect. 6.4/10.

Beetroot (Dietary Nitrate) · 6.9Pre-Workout
Supplementbeta-alanine + citrulline + caffeine improve high-intensity endurance + output
⚑ at clinical doses, not proprietary blends6.9/10SAC Efficacy Score™- Effect size45%Moderate
- Evidence40%Strong
- Reliability15%Works for many
Why these numbers?
Effect size: Caffeine improved endurance performance by ~2–4% across 46 studies (Southward 2018); beta-alanine and citrulline add high-intensity capacity and blood flow when dosed honestly. 5.8/10.
Evidence: Caffeine's endurance effect is meta-analysed; the blend is judged on disclosed doses: 8.0/10.
Reliability: Tolerance, GI upset on the run and hidden doses in proprietary blends: 7.0/10.
Caffeine does the heavy lifting — the rest must be dosed.

Supplementmore output in the 30–180 s effort window (carnosine buffer)
⚑ the 30–180 s effort window only6.6/10SAC Efficacy Score™- Effect size45%Moderate
- Evidence40%Strong
- Reliability15%Specific cases
Why these numbers?
Effect size: Chronic beta-alanine raises muscle carnosine and improves exercise capacity in the 30-second-to-10-minute window across 40 studies (Saunders 2017) — the buffer for the final surge. 5.8/10.
Evidence: A large meta-analysis: 7.8/10.
Reliability: Helps high-intensity intervals and finishing kicks; little for 3-hour steady efforts. 5.6/10.

- Evidence40%Strong
- Reliability15%Specific cases
Why these numbers?
Effect size: A 2% bodyweight fluid loss measurably impairs aerobic performance, more so in heat (Sawka 2007); sodium replacement sustains plasma volume on long, hot sessions. 5.5/10.
Evidence: The ACSM position stand and heat-stress physiology: 7.8/10.
Reliability: Pays on efforts over ~90 minutes, in heat, or for heavy sweaters; adds nothing to a cool 45-minute run. 6.0/10.

Supplementless exercise-induced inflammation; sustains training volume

- Evidence40%Moderate
- Reliability15%Works for many
Why these numbers?
Effect size: Omega-3 reduced the inflammatory response to eccentric exercise (Jouris 2011) and has consistent, modest effects on recovery and training tolerance in athletes (Philpott 2019). Volume, not speed — 4.8/10.
Evidence: Small trials and a 2019 review: 7.6/10.
Reliability: Reliable in athletes with low fish intake; 1–2 g/day for 6+ weeks. 7.0/10.

Omega-3 (EPA/DHA) · 6.3Magnesium Glycinate
Supplementfewer exercise cramps + better recovery (replaces sweat losses)
⚑ mainly if depleted / cramping5.9/10SAC Efficacy Score™- Effect size45%Modest
- Evidence40%Moderate
- Reliability15%Specific cases
Why these numbers?
Effect size: Magnesium status affects muscle function and exercise recovery (Nielsen 2006), but the Cochrane review found no clear benefit of magnesium for exercise cramps in the general population (Garrison 2020). Replacing sweat losses is the honest case — 4.6/10.
Evidence: Good physiology review against a cautious Cochrane null: 7.6/10.
Reliability: Low-magnesium athletes respond; the cramp claim does not hold for the replete. 5.4/10.
Replaces what you sweat out — cramps are another story.

- Evidence40%Moderate
- Reliability15%Specific cases
Why these numbers?
Effect size: Two weeks of CoQ10 raised muscle CoQ10 and modestly improved time to exhaustion in trained and untrained subjects (Cooke 2008); the anti-fatigue crossover agrees (Mizuno 2008). Small — 4.4/10.
Evidence: Small trials, mixed results elsewhere: 7.0/10.
Reliability: Older and statin-treated athletes respond most; young athletes barely. 5.2/10.

⚑ only militaris fruiting body with disclosed beta-glucan is worth buying4.4/10SAC Efficacy Score™- Effect size45%Modest
- Evidence40%Preliminary
- Reliability15%Narrow
Why these numbers?
Effect size: Three weeks of C. militaris improved VO₂max and time to exhaustion in a small crossover (Hirsch 2017); Cs-4 improved metabolic threshold in older adults (Chen 2010). Small, unreplicated — 4.2/10.
Evidence: Two small trials, mixed elsewhere: 4.6/10.
Reliability: Species and beta-glucan content vary wildly between products: 4.4/10.

Cordyceps (C. militaris) · 4.4BCAAs
Supplementmay blunt central fatigue + support recovery on long/fasted sessions (Blomstrand 2006); effect is modest
⚑ mostly an intra-workout convenience for fasted/endurance/low-protein cases4.1/10SAC Efficacy Score™- Effect size45%Small
- Evidence40%Limited
- Reliability15%Narrow
Why these numbers?
Effect size: The central-fatigue hypothesis — BCAAs compete with tryptophan at the blood-brain barrier and may delay the 'I'm done' signal on long, fasted sessions (Blomstrand 2006) — is coherent but has never produced a reliable performance gain in trained athletes. 3.4/10.
Evidence: Mechanistic and small-trial support, no meta-analysis showing faster times: 5.0/10.
Reliability: Only plausible when protein intake is low or the session is fasted; redundant on top of whey. 4.0/10.
A coherent theory without a stopwatch to back it.
