Beat fatigue at the source — the supplements that genuinely restore energy when something's missing, ranked honestly (most 'energy' pills do nothing).

Ranked Solutions

Ranked by how much each one actually moves the needle — our SAC Efficacy Score™. Supplements, protocols and gear compete in ONE ranking.

  1. Iron

    Supplement

    resolves a leading, fixable cause of fatigue when ferritin is low

    ⚑ only if iron-deficient
    • Effect size45%Moderate
    • Evidence40%Strong
    • Reliability15%Specific cases
    Why these numbers?

    Effect size: In non-anaemic women with low ferritin, 80 mg iron for 12 weeks cut fatigue by half versus placebo (Vaucher 2012). One of the most common and most fixable causes of tiredness — 6.6/10.

    Evidence: A well-run RCT plus a large deficiency literature: 8.6/10.

    Reliability: Only for low ferritin; iron in a replete person is harmful, not neutral. 5.6/10.

    The most fixable cause of constant tiredness.

    non-anaemic women with ferritin <50 — RCTCMAJ 2012 ↓

    Test first. Iron in a replete body is harm, not insurance.

  2. Vitamin B12

    Supplement

    restores energy + clears brain fog when B12 is low

    ⚑ biggest if B12 is low (vegans, older adults)
    • Effect size45%Moderate
    • Evidence40%Strong
    • Reliability15%Specific cases
    Why these numbers?

    Effect size: Deficiency causes genuine fatigue and brain fog and is common in vegans, older adults and metformin users; correcting it restores energy within weeks (Stabler 2013). 6.0/10.

    Evidence: Well-characterised deficiency medicine, few RCTs in the non-deficient: 8.4/10.

    Reliability: Pays only if you're low — test B12 or methylmalonic acid first. 5.8/10.

    Fog and fatigue with a blood test behind them.

    Pays only if you're low; then it pays big.

  3. Creatine Monohydrate

    Supplement

    replenishes cellular ATP for a broad, reliable anti-fatigue effect

    • Effect size45%Modest
    • Evidence40%Strong
    • Reliability15%Works for many
    Why these numbers?

    Effect size: Refuels cellular ATP; 8 g/day for 5 days reduced mental fatigue on repeated calculation tasks (Watanabe 2002), and the ISSN calls the safety record the cleanest in sport (Kreider 2017). A broad, reliable anti-fatigue effect — 5.2/10 for energy specifically.

    Evidence: Hundreds of trials, a handful on mental fatigue: 8.2/10.

    Reliability: Works in most people; vegetarians respond most. 7.6/10.

    Cellular ATP, refilled.

    8 gdaily × 5 days↓ mental fatigueon repeated tasks

  4. Pre-Workout

    Supplement

    acute caffeine-driven energy + focus boost

    ⚑ acute, and caffeine tolerance builds
    • Effect size45%Moderate
    • Evidence40%Moderate
    • Reliability15%Works for many
    Why these numbers?

    Effect size: Caffeine at 3–6 mg/kg lifts power and strength acutely (Grgic 2018); citrulline and tyrosine add focus and pump. The most reliable acute lift on this page — for training, not for the afternoon slump. 5.5/10.

    Evidence: Caffeine meta-analysed; the blend judged on disclosed doses: 7.4/10.

    Reliability: Tolerance and sleep cost; proprietary blends hide the doses. 6.8/10.

    A reliable lift, for the session.

  5. Rhodiola Rosea

    Supplement

    reduces stress-related fatigue + burnout in trials

    • Effect size45%Moderate
    • Evidence40%Moderate
    • Reliability15%Works for many
    Why these numbers?

    Effect size: SHR-5 extract reduced burnout-type fatigue and improved attention in a 28-day RCT (Olsson 2009); an open-label study in prolonged fatigue agreed (Lekomtseva 2017). 5.6/10.

    Evidence: One good RCT plus supportive open-label data: 7.4/10.

    Reliability: Standardisation (3% rosavins, 1% salidroside) decides whether you get the trial dose. 6.6/10.

    For the burnt-out, with a trial behind it.

  6. CoQ10 (Ubiquinol)

    Supplement

    mitochondrial energy support, clearest in older / statin users

    • Effect size45%Modest
    • Evidence40%Moderate
    • Reliability15%Works for many
    Why these numbers?

    Effect size: 300 mg for 8 days cut physical fatigue and improved performance in a crossover trial (Mizuno 2008), and it relieves statin-induced muscle symptoms in meta-analysis (Qu 2018). Clearest in older and statin users — 5.4/10.

    Evidence: Small crossover trial plus a solid statin meta-analysis: 7.6/10.

    Reliability: Ubiquinol after 40, with a fat-containing meal; young replete people notice little. 6.4/10.

    Mitochondrial cofactor, clearest over 40.

    300 mgCoQ10 × 8 days↓ fatigue+ ↑ performance

    For statin users and the over-40s, not for the young and rested.

    CoQ10 (Ubiquinol) · 6.4
  7. Electrolyte Powder

    Supplement

    restores energy specifically when the cause is dehydration / electrolyte loss

    ⚑ only when fatigue is electrolyte-driven
    • Effect size45%Modest
    • Evidence40%Moderate
    • Reliability15%Specific cases
    Why these numbers?

    Effect size: Dehydration of 2% bodyweight measurably impairs performance and perceived effort (Sawka 2007). When fatigue is fluid- or sodium-driven — heat, fasting, low-carb — replacing electrolytes restores it fast. 4.2/10, because that's a narrow cause.

    Evidence: ACSM position stand and heat-stress physiology: 6.4/10.

    Reliability: Only helps when dehydration is the cause; sugary formulas add calories for nothing. 5.2/10.

    When the fatigue is fluid, this fixes it in an hour.

    For heat, fasting and low-carb — not as a daily habit.

  8. Multivitamin

    Supplement

    fixes the fatigue that comes from genuine micronutrient gaps; no energy boost if you are already replete

    ⚑ energy lift mainly if you were deficient
    • Effect size45%Small
    • Evidence40%Limited
    • Reliability15%Specific cases
    Why these numbers?

    Effect size: Fixes the fatigue that comes from real gaps — a high-dose B-complex with C and minerals cut mental fatigue in healthy men over 33 days (Kennedy 2010) — but adds nothing if you're replete. 3.8/10.

    Evidence: A few placebo-controlled trials on mood and fatigue: 5.6/10.

    Reliability: Responders are the people with a shortfall; that's who should take it. 5.6/10.

    Insurance for gaps, not a stimulant.

    Test iron, B12 and D first — they're the gaps that cost energy.

  9. Cordyceps (C. militaris)

    Supplement

    mechanistically coherent energy story; human trials are small, mixed and lack replication

    ⚑ militaris fruiting body with disclosed beta-glucan only
    • Effect size45%Small
    • Evidence40%Preliminary
    • Reliability15%Narrow
    Why these numbers?

    Effect size: A coherent mitochondrial story and two small trials: Cs-4 improved metabolic threshold in older adults (Chen 2010) and C. militaris improved high-intensity exercise tolerance after 3 weeks (Hirsch 2017). Everyday energy was never the endpoint. 4.0/10.

    Evidence: Small exercise trials, no replication at scale: 4.6/10.

    Reliability: Species and beta-glucan content vary wildly between products: 4.4/10.

    Coherent mechanism, small trials.

    4 gC. militaris × 3 weeks↑ VO₂max+ time to exhaustion

  10. NMN / NAD+

    Supplement

    raises NAD+; subjective energy benefit not demonstrated in humans

    ⚑ early / mixed human evidence
    • Effect size45%Small
    • Evidence40%Limited
    • Reliability15%Narrow
    Why these numbers?

    Effect size: NMN reliably raises blood NAD+ (Irie 2020; Yi 2023) and improved a 6-minute walk in one 60-day trial — but a felt everyday-energy benefit has not been shown in humans. 3.8/10.

    Evidence: Small human trials with biomarker endpoints: 4.8/10.

    Reliability: Product purity and dose vary; long-term data is thin: 4.2/10.

    Raises the biomarker, not yet the feeling.

  11. Bee Pearl / Bee Pollen

    Supplement

    popular energy/vitality claims rest on small, preliminary or test-tube studies, not human RCTs

    ⚑ bee/pollen allergen — spot-test first; royal jelly riskiest
    • Effect size45%Small
    • Evidence40%Preliminary
    • Reliability15%Narrow
    Why these numbers?

    Effect size: A dense micronutrient matrix with a long traditional record — but the energy and vitality claims rest on small, preliminary or test-tube work, not human RCTs (Denisow 2016). 3.2/10.

    Evidence: Reviews of composition and animal data, no human energy trial: 3.2/10.

    Reliability: Composition varies by hive and season, and pollen allergy is a real risk: 3.6/10.

    Tradition, not trials.
