About monthlees
The supplement industry is built on inflated pricing, confusing labels, and aggressive marketing.
Monthlees exists to fix that.
We believe:
- Supplements should be clinically dosed
- Pricing should be transparent
- Testing should be independent
- And customers shouldn't pay for influencer commissions or retail margins
Instead of hiding costs inside the product price, we use a simple membership model — so you pay what supplements actually cost to make.

What is Japanese knotweed extract?
Japanese knotweed (Polygonum cuspidatum) root is a botanical source of resveratrol. This formula uses an extract standardized to 98% resveratrol — 150 mg per serving — as disclosed on the supplement facts panel.
How is this different from standalone resveratrol?

Why I created monthlees...
When I was 19 years old, I was diagnosed with a brain tumor. That experience forced me to start asking deeper questions about how the human body actually works.
Over the next 18 months, I immersed myself in studying health, nutrition, and neuroscience — eventually earning my degree in Neuroscience from Duke University. Along the way, I discovered something powerful: the body is incredibly resilient & inherently self-healing when it’s given the right support.
Strategic nutrition and supplementation became a major part of my own health journey. And over the last two decades, I’ve devoted my life to helping millions of people around the world take a more proactive role in their health.
That experience completely changed how I thought about health — and ultimately shaped the way Monthlees was built.
I created Monthlees because I was tired of seeing people pay premium prices for supplements that were under-dosed, over-marketed, and difficult to trust.
My goal is simple: build the kind of brand I would want for myself and my family — with better ingredients, transparent formulas, meaningful dosages, and a business model built on long-term trust.
