Mitochondria

The powerhouse of the cell. How 36 trillion cells make energy, and every supplement and habit with real evidence for building, fueling, and protecting the machinery.

The short answer

Every cell spends ATP to do anything at all, and roughly 90% of it comes from mitochondria. An adult male runs about 36 trillion cells, a female about 28 trillion, each with hundreds to thousands of mitochondria. Usable energy is capped not by how much you eat but by how many mitochondria you have, how clean they run, and whether the electron transport chain has its cofactors. Exercise and sleep move those numbers more than any pill; the supplements below amplify them.

Glycolysis

Cytoplasm. Glucose splits into pyruvate. Net 2 ATP.

Krebs cycle

Mitochondrial matrix. Pyruvate is fully oxidized into NADH and FADH₂, the electron carriers.

Oxidative phosphorylation

Inner membrane. The electron transport chain pumps protons; ATP synthase spins them into ~28 ATP.

One glucose molecule yields 30 to 32 ATP in total, nearly all of it from the mitochondrial stage. CoQ10 is the shuttle between Complexes I/II and III. NAD+ and FAD are the carriers. Magnesium is bound to every ATP that does work. That is why the cofactor list comes first.

A Strong human evidenceB Good mechanism, moderate human dataC Promising, thin human data

Fuel the electron transport chain

Direct cofactors. Without these the chain runs short no matter what else you take; deficiency caps ATP output.

  • A
    Ubiquinol (CoQ10)100–300 mg with fat
    Carries electrons from Complex I/II to III. Falls ~50% by age 80; statins deplete it. Q-SYMBIO: 300 mg/day halved cardiac events in heart failure.
  • A
    Creatine monohydrate3–5 g daily
    Phosphocreatine regenerates ATP in seconds. The best-studied supplement in sports science; also helps cognition under sleep loss.
  • A
    Magnesium300–400 mg glycinate
    ATP only works as Mg-ATP. Roughly half of adults run low.
  • A
    B-complexB1, B2, B3, B5, B12
    B2 becomes FAD, B3 becomes NAD+, B5 becomes coenzyme A. Riboflavin is underrated; benfotiamine is the fat-soluble B1.
  • B
    NAD+ precursorsNMN or NR 250–1,000 mg
    NAD+ is the electron carrier Complex I runs on and what sirtuins need. Declines with age.
  • B
    Niacinamide (vitamin B3)250–500 mg; or niacin 25–100 mg
    Both are B3 and both feed NAD+, at a fraction of the price of NR. Niacinamide does not flush, so it is the daily form; plain niacin flushes above ~50 mg but is the only one that lowers LDL (at 1–2 g, under a doctor). High-dose niacin raised NAD+ and muscle strength in a 2020 mitochondrial-myopathy trial.
  • A
    Trace mineralsIron, copper, zinc, selenium, manganese
    Iron-sulfur clusters, Complex IV, superoxide dismutase. Only supplement iron if ferritin says so.
  • C
    Vitamin K2 (MK-7)100–200 mcg
    Acts as a mitochondrial electron carrier in some models, besides directing calcium.
  • C
    D-ribose5 g
    The sugar backbone of ATP. Small trials in heart failure and fibromyalgia.
  • B
    MitoQ / SkQ110–20 mg
    CoQ10 chemically targeted to accumulate inside mitochondria. Pricier than ubiquinol.

Build new mitochondria

Signals that switch on PGC-1α, AMPK, and the sirtuins, the pathways that drive mitochondrial biogenesis. Exercise does this best; these amplify it.

  • B
    PQQ10–20 mg
    Activates CREB and PGC-1α so the cell builds more mitochondria. Trials show better sleep, less fatigue, sharper attention.
  • B
    Pterostilbene / resveratrol50–100 mg / 150–500 mg
    SIRT1 and PGC-1α activators. Pterostilbene absorbs far better than resveratrol.
  • B
    Berberine500 mg 2–3× with meals
    AMPK activator with metformin-like effects on blood sugar, which itself lowers mitochondrial ROS.
  • C
    Quercetin / fisetin500 mg / 100 mg
    Flavonoids with senolytic effects: they help clear worn-out cells.
  • C
    Hydroxytyrosol10–25 mg or olive oil
    Olive polyphenol that upregulates PGC-1α.
  • B
    EGCG (green tea)300–400 mg or 3 cups
    Catechin that supports biogenesis and fat oxidation.
  • A
    Nitrate (beetroot)1 cup juice
    Lowers the oxygen cost of exercise; more ATP per breath.
  • C
    Shilajit250–500 mg
    Fulvic acid; one study showed it amplified CoQ10. Weak evidence.

Clear damaged mitochondria

Mitophagy and autophagy. Old, leaky mitochondria produce more ROS and less ATP; clearing them makes room for healthy ones.

  • B
    Urolithin A500–1,000 mg
    Made by gut bacteria from pomegranate ellagitannins; most people make little. Trials show better muscle endurance and mitochondrial gene expression in older adults.
  • B
    Spermidine1–6 mg (wheat germ extract)
    Autophagy inducer tied to longevity in population studies.
  • B
    Taurine1–3 g
    Stabilizes mitochondrial tRNA. A 2023 Science paper linked falling taurine to aging and showed health gains in animals. Cheap.
  • B
    Sulforaphane20–40 mg (broccoli sprout)
    Strongest dietary Nrf2 activator: switches on your own antioxidant enzymes.

Protect the membranes

Mitochondria are the largest source of reactive oxygen species in the body. These defend the inner membrane and rebuild glutathione, the master antioxidant.

  • B
    Alpha lipoic acid (R-ALA)300–600 mg
    Cofactor for pyruvate dehydrogenase, recycles vitamin C, E, and glutathione. Pairs with ALCAR in the classic Ames protocol.
  • B
    Acetyl L-carnitine (ALCAR)500–1,500 mg
    Shuttles fatty acids into mitochondria for burning. Crosses the blood-brain barrier better than plain carnitine.
  • B
    L-carnitine tartrate1–2 g
    Same carrier, the form muscle prefers. Take ALCAR for brain, tartrate for training.
  • A
    Fish oil (EPA + DHA)1–2 g EPA/DHA
    Incorporates into mitochondrial membranes, lowers inflammatory signaling. Strongest in people with metabolic dysfunction or heart disease.
  • A
    NAC + glycine (GlyNAC)600–1,200 mg NAC + 1–3 g glycine
    Baylor trials in older adults: restored glutathione, improved mitochondrial function, lower oxidative stress. Strong recent data.
  • B
    Astaxanthin4–12 mg
    Spans the full membrane bilayer. Good for exercise recovery.
  • B
    Melatonin0.5–3 mg at night
    Mitochondria make their own. A potent mitochondrial antioxidant, not only a sleep hormone.
  • B
    Curcumin500 mg phytosome
    Nrf2 activation and inflammation. Needs piperine or a phytosome form to absorb.
  • A
    Berry polyphenolsA cup a day
    Anthocyanins activate Nrf2. Whole food beats megadosed isolated antioxidants, which can blunt the useful ROS signal from exercise.

Alternative fuel

Ketones skip glycolysis and enter the Krebs cycle directly, yielding more ATP per unit of oxygen.

  • B
    MCT oil1–2 tbsp
    Converts to ketones within an hour. Start small or it will send you to the bathroom.
  • C
    Ketone esters10–25 g
    Instant ketosis without fasting. Expensive and taste terrible; elite endurance data is mixed.

Adaptogens

Worth knowing, thinner evidence, mostly subjective fatigue measures.

  • C
    Cordyceps1–3 g
    Modest VO₂max data.
  • C
    Rhodiola200–400 mg
    Fatigue and stress; morning only.

Experimental: read before touching

Low-dose methylene blue works as an alternative electron carrier in the transport chain. Real mechanism, real risk: it is an MAOI and can cause serotonin syndrome with SSRIs or SNRIs, and the dose window is narrow. Not a casual add.

Where to start, in order

  1. 01Creatine · Strongest evidence, cheapest, safest
  2. 02Magnesium + B-complex · Fix the cofactors before adding anything exotic
  3. 03Fish oil · Strong for inflammation, moderate for energy
  4. 04Taurine + GlyNAC · Cheap, new, well-run human trials
  5. 05Ubiquinol · Especially past 40 or on a statin
  6. 06NAD+ precursor (niacinamide, NR, or NMN) · Good mechanism, human data still maturing; niacinamide is the cheap route
  7. 07ALA + ALCAR · The classic pair for aging mitochondria
  8. 08Urolithin A + PQQ · Clear the old, build the new. The most speculative tier

Bigger levers than any supplement

  1. 01Zone 2 cardio plus occasional intervals: the single best-proven driver of mitochondrial biogenesis
  2. 02Sleep 7 to 9 hours: mitochondrial repair runs on the circadian clock
  3. 03Time-restricted eating: fasting windows trigger mitophagy
  4. 04Cold plunges and sauna: hormetic stress that builds mitochondrial density
  5. 05Morning sunlight: sets the clock that governs mitochondrial gene expression
  6. 06Stable blood sugar: glucose spikes raise mitochondrial ROS
  7. 07Cut smoking, excess alcohol, overtraining, and chronic stress: cortisol itself impairs mitochondria
