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.

Frequently asked questions
Everything you need to know about Monthlees member pricing, subscriptions, and how checkout works.
Do you have phthalates in the fragrances you use?
No. The perfume compositions we use do not contain phthalates. Phthalates are synthetic raw materials — the fragrance compositions in our products are made from natural raw materials.
Does it contain fragrance, and is it safe for sensitive skin?
Yes, it contains a minimal amount of natural-origin fragrance (listed as Parfum in the INCI) to balance the natural scent of raw ingredients. The shampoo is dermatologically tested and carefully formulated to minimize irritation — suitable for sensitive scalps.
Can men use this shampoo?
Yes. Betaine Strengthen & Repair Shampoo is gender-neutral and suitable for anyone with a sensitive scalp — the white floral aroma with aquatic and red fruit notes is delicately fragranced, not overpowering.
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.
