A patented, clinically proven ingredient with a consistent and measurable effect on resting metabolic rate and body composition.
Clear, research-backed benefits to build your product story around.
Acute RMR study: randomized, double-blind, placebo-controlled crossover in 60 men and women. Theolim® showed significantly higher metabolic rate than placebo, both at rest and post exercise.
16-week figures: Weight management study I, randomized, double-blind, placebo-controlled, 120 subjects. Resting metabolic rate measured by indirect calorimetry, shown as the difference versus placebo (all p < 0.01).
Mean changes reported in 120 subjects in a randomized, double-blind, placebo-controlled study — one of two 16-week weight management trials.
Theolim® brings together Citrus aurantiifolia rind and Theobroma cacao seed extracts. The formulation was selected after screening more than 1,000 botanical extracts.
A lift in calorie burn within hours, and results that hold across four months of daily use.
Four completed clinical trials — an acute RMR study, a pre-workout performance study, and two 16-week weight management studies — sit on top of preclinical mechanism work and safety monitoring, examining how Theolim® performs at rest, before exercise, and over sustained use.
The program spans four completed human trials — an acute RMR study, a pre-workout performance study, and two 16-week weight management studies — on top of preclinical mechanism work and safety monitoring throughout. Each study asks a different question; together they form a more complete picture.
A randomized, double-blind, placebo-controlled crossover study evaluated a single dose against placebo, tracking resting metabolic rate, fat oxidation and mood at rest and during exercise.

Full protocols, populations and results for all four studies are compiled in our ingredient dossier.
Request the full dossierFrom our acute RMR study. Our separate pre-workout study examined exercise capacity, perceived exertion and vascular function; those results are available on request.
Resting metabolic rate rose 5× versus placebo at 120 minutes and 189% at 180 minutes post-dose.
Metabolic rate increased 19% versus placebo during exercise, with elevated fat oxidation before and after training.
Free fatty acids rose to 177.0 µM after exercise, versus 146.7 µM with placebo.
Self-reported mood scores (POMS-SF) improved to a greater extent than placebo, both at rest and after exercise.
Weight management study I enrolled overweight adults aged 25 to 55 years with BMI values between 25 and 29.9 kg/m². Eligibility details for our other three studies are available on request.
No. Theolim® is a food supplement ingredient, not a licensed medicinal product. It isn't intended to diagnose, treat, cure, or prevent any disease.
People with pre-existing health conditions, those who are pregnant or nursing, and those taking medication should consult a qualified healthcare professional before using any supplement containing the ingredient.
450 mg once daily. Theolim® is non-stimulant and caffeine-free, so it doesn't carry the dosing-window restrictions typical of stimulant-based actives.
