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.

Metabolic flexibility support
MCTs and BHB complement the body's natural fat-based energy pathways — 800 mg HydroxyFuel Blend with constituents listed on the label.*
-
Fasting transition support
Exogenous BHB provides supplemental ketones during intermittent fasting or ketogenic diets — when endogenous ketone production is ramping up.*
-
Electrolyte support
Calcium, magnesium, and sodium BHB mineral salts support electrolyte balance during metabolic shifts — 146 mg calcium per serving on the supplement facts panel.*
-
Blend transparency
800 mg blend weight with MCT powder and individual BHB salts named — not a mystery undisclosed keto blend.*
How it works
-
Step 1: Fuel
MCT powder provides rapidly absorbed medium-chain fatty acids — while BHB mineral salts supply exogenous ketones to complement the body's natural fat-based energy pathways.*
-
Step 2: Transition
Designed to support smoother energy during intermittent fasting or reduced carbohydrate intake — when the body shifts toward fat metabolism.*
-
Step 3: Balance
Calcium, magnesium, and sodium from BHB mineral salts contribute to electrolyte balance during metabolic transitions — disclosed on every label.*

Medium-chain triglycerides and energy metabolism
Reviews report that MCTs are rapidly oxidized for energy and may support ketone production — relevant to MCT + BHB combination positioning.
Ketone bodies during fasting
Metabolic reviews describe how fasting increases endogenous ketone production — the physiological context for BHB supplementation during reduced carbohydrate intake.
Mineral balance during ketogenic diets
Clinical reviews discuss electrolyte shifts during ketogenic and low-carb diets — supporting mineral salt inclusion in BHB formulations.

How Monthlees HydroxyFuel stacks up
Many keto supplements hide BHB doses in proprietary blends without naming constituents. HydroxyFuel lists 800 mg blend weight with MCT powder and individual BHB salts on the label.

Frequently asked questions
Everything you need to know about Monthlees member pricing, subscriptions, and how checkout works.
What is BHB in HydroxyFuel?
BHB (β-hydroxybutyric acid) is a ketone body the body produces during fat metabolism. HydroxyFuel includes calcium, magnesium, and sodium BHB mineral salts in the 800 mg HydroxyFuel Blend — providing exogenous ketones alongside MCT powder to complement natural ketone production during fasting or low-carb intake.
How is HydroxyFuel different from LipoFuel™?
HydroxyFuel is a focused MCT + BHB keto blend in two capsules — 800 mg HydroxyFuel Blend with BHB mineral salts. LipoFuel is a broader metabolic stack with L-carnitine, CLA, garcinia, chromium, and 14+ actives in four capsules. Choose HydroxyFuel for exogenous ketones and MCT; choose LipoFuel for a wider fat-metabolism ingredient panel.
Is HydroxyFuel vegetarian?
No. HydroxyFuel uses gelatin capsules and contains bovine gelatin. It is not suitable for vegetarians or vegans. Other ingredients include brown rice flour as listed 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.
