again — naturally.


MCB Oil is a concentrated plant-based oil that supports your body's natural balance, energy and overall wellbeing. Made from pure organic Maca — no prescription needed in New Zealand and Australia.

Not a lifetime commitment. The goal is to restore your body's natural balance. As you feel better, you step down — from MCB Oil to 10:1 concentrated Maca, then to regular Maca powder for everyday maintenance.

How it works

Your body already knows how to take care of itself.
MCB Oil just gives it a helping hand.

Your body has a built-in system for supporting balance across mood, sleep, energy and everyday wellbeing. MCB Oil helps support this system — no prescription needed in New Zealand and Australia.

1

Your body has a natural balance system

Modern life can wear it down over time.

2

Maca has natural compounds that support it

Backed by University of Otago research.

3

MCB Oil is 100× more concentrated

A few drops does what powder alone can't.

4

Your body makes more feel-good chemicals

Balance restored naturally from within.

5

Then you step down — naturally

MCB Oil → 10:1 Maca → Maca powder. Balance, not dependency.

Covered by Arthritis New Zealand — a pharmacist at Arthritis NZ featured MCB Oil in their 2026 newsletter, alongside independent University of Otago lab research findings.

MCB Oil vs The Other Oil

The same idea — done better.

Both work on your body's natural balance system. But one comes with legal restrictions, workplace risks and unwanted side effects. MCB Oil doesn't.


The Other Oil

Plant-based — with restrictions

Needs a prescription in New Zealand and Australia
Can show up on a workplace drug test
Can make you drowsy or feel foggy
Not safe to drive or operate machinery after taking
Sourced from a plant some people aren't comfortable with
Quality and purity often difficult to verify

Patent filed formulation — MCB Oil® is a world-first, patent-pending concentrated Maca extract developed by Dr Corin Storkey, Medicinal Chemist, Wellington, New Zealand.

How to take it

Simple — just a few drops under your tongue.

This gets it into your bloodstream much faster than swallowing a pill or mixing it into food.

1

Shake the bottle

Give it a quick shake before each use to make sure everything is evenly mixed.

2

Drop under your tongue

Start with 2–3 drops. Work up to 8–15 drops a day as your body adjusts.

3

Hold for 60 seconds

Wait a full minute, then swallow. That's it — you're done.
