§.01The short answer.

Maca Extract 400 mg is a vegetable capsule formulated around a single idea: the andean root. Take one capsule a day, with dinner, with a glass of water. Judge after four weeks.

The rest of this guide exists because the maca root supplement aisle is a marketing jungle. You don't need a stack. You need the right dose of the right molecule, held consistently.

Most supplement failure isn't about the molecule — it's about the dose, the form, and whether anyone remembered to take it.— Liv Hartwell, PharmD

§.02What it actually does.

The claims worth making, in plain language:

AreaWhat to expect
EnergyCellular fuel — no caffeine spike, no afternoon crash.
VitalityEnergy, drive, and drive-through — in that order.
Pharmacist's note

Dose matters more than brand.

Vesper's Maca Extract 400 mg is dosed to the amounts used in the trials that actually showed effect — not the amounts that fit a margin.

§.03Dose, timing, and how to take it.

90
90 capsules

One bottle of Vesper's Maca Extract 400 mg is 90 capsules for $24. Roughly a 3-month supply at the starting dose.

§.04What the trials actually show.

The honest version of the evidence. Maca Extract 400 mg has roughly 26 relevant trials in the last fifteen years.

Energy.

Cellular fuel — no caffeine spike, no afternoon crash. The effect size across the better-designed trials is modest and real — not miraculous. Treat the moderate, repeated signals as the truth.

Vitality.

Energy, drive, and drive-through — in that order. The effect size across the better-designed trials is modest and real — not miraculous. Treat the moderate, repeated signals as the truth.

§.05Side effects and who should skip it.

§.06What to look for on a label.

  1. Active dose listed separately. Not buried in a proprietary blend.
  2. Third-party tested. USP, NSF, or Informed Choice.
  3. Short ingredient list. Active + capsule shell. Past six lines, you're paying for filler.
  4. No "complex" language. Marketing word that can legally mean anything.
  5. A real manufacturer address. Not a P.O. box.

§.07Frequently asked.

How long until I notice something?

Four weeks is the honest floor. If nothing has changed after eight weeks at the full dose, Maca Extract 400 mg probably isn't your missing piece.

Can I stack it with other supplements?

Almost always yes. Plays well with a daily multi, D, magnesium, and fish oil.

Is the capsule form better?

For this molecule, yes. Clean, well-tested delivery for this molecule.

Can I take it forever?

No cycling needed. Take daily, judge quarterly.

What if it doesn't work for me?

Return within 60 days — even empty — and we refund it.


§.08The bottom line.

Maca Extract 400 mg is the andean root. Buy the therapeutic dose, take one capsule daily, and check in at four weeks. If it's working you'll know. If it isn't, the bottle goes back.

Ours is $24 for 90 capsules, vegetable capsule, USP-tested.
