Feel like yourself
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.

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.
Your body has a natural balance system
Modern life can wear it down over time.
Maca has natural compounds that support it
Backed by University of Otago research.
MCB Oil is 100× more concentrated
A few drops does what powder alone can't.
Your body makes more feel-good chemicals
Balance restored naturally from within.
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.
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
MCB Oil
Pure Andean Maca — no restrictions
MCB Oil is made from concentrated Andean Maca — a plant native to Peru. It is not derived from, and does not contain, any scheduled substances. No prescription is required to purchase or use MCB Oil in New Zealand or Australia.
