Product Overview
Product Overview
This targeted blend combines medium-chain triglycerides (MCTs) with beta-hydroxybutyrate (BHB) mineral salts to support the body’s natural fat-based energy pathways. MCTs are rapidly absorbed fatty acids that can be utilized for energy, while BHB provides a supplemental ketone source to complement the body’s endogenous ketone production.
Essential minerals — including calcium, magnesium, and sodium — are included to support electrolyte balance during fasting transitions.
About Monthlees
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.
