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.

Methylsulfonylmethane and joint health
Randomized trials suggest MSM supplementation may reduce joint pain and improve physical function in adults with osteoarthritis — aligned with the 50 mg per-serving dose.
Boswellia serrata extract and joint function
Controlled studies report improvements in joint pain and mobility with Boswellia extract standardized to boswellic acids — complementing turmeric in multi-botanical joint formulas.
Oral hyaluronic acid and joint comfort
Reviews of oral hyaluronic acid supplementation discuss its role in supporting synovial fluid viscosity and joint lubrication — relevant to the sodium hyaluronate dose on the label.

How Monthlees Flex+™ stacks up

Frequently asked questions
Everything you need to know about Monthlees member pricing, subscriptions, and how checkout works.
Is Flex+ glucosamine shellfish-free?
Yes. Flex+ uses GlucosaGreen® vegetal glucosamine HCl — a plant-based source of glucosamine, not glucosamine sulfate derived from shellfish. Each serving lists 200 mg on the supplement facts panel. If you need shellfish-free joint support, Flex+ is the Monthlees option; CurcuPrime™ uses shellfish-derived glucosamine sulfate.
How is Flex+ different from CurcuPrime™?
Flex+ focuses on plant-based glucosamine, higher-dose MSM (50 mg), hyaluronic acid, white willow bark, and olive oil — without chondroitin or shellfish. CurcuPrime is a broader 11-ingredient stack with standardized curcuminoids, chondroitin, ginger, and shellfish-derived glucosamine. Choose Flex+ for plant glucosamine and hyaluronic acid; choose CurcuPrime for a maximum-ingredient turmeric stack.
Why is olive oil in the formula?
Turmeric, Boswellia, and other botanical actives in Flex+ are fat-soluble. Olive oil is included in the capsule matrix to support absorption of these compounds alongside BioPerine® black pepper extract (95% piperine) — as listed in other ingredients on the supplement facts panel.
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.
