Introduction
CortiSlim is a nutraceutical formulation marketed as a weight‑management supplement. The product combines a proprietary blend of plant extracts, amino acids, and trace minerals, with the goal of supporting metabolic rate, appetite control, and fat oxidation. It has been available on the market since the late 2010s and is sold primarily through online retail channels and specialty health stores. The formulation is positioned within the broader category of dietary supplements that claim to aid in weight loss or body composition improvement without the need for prescription medication.
History and Development
Origins
The concept for CortiSlim emerged from research conducted by a team of nutrition scientists at a European university. Early investigations focused on the synergistic effects of certain phytochemicals known to influence thermogenesis and satiety. In 2015, a research consortium partnered with a supplement manufacturing company to translate laboratory findings into a consumer‑ready product.
Formulation Process
During the initial development phase, several candidate ingredients were evaluated for safety, bioavailability, and efficacy. The final composition was selected based on a combination of pre‑clinical studies and expert panel reviews. The manufacturing facility operates under Good Manufacturing Practices (GMP) and is certified for quality assurance by an independent third‑party organization.
Market Launch
CortiSlim was introduced to the European market in 2018, followed by a launch in the United States in 2019. The marketing strategy emphasized natural ingredients, scientific backing, and a non‑prescription approach to weight management. Over the subsequent years, the product expanded into additional markets across Asia, South America, and Australia.
Composition and Production
Key Ingredients
The active blend in CortiSlim includes:
- Green Tea Extract (Camellia sinensis) – standardized to contain 50 % catechins, including epigallocatechin gallate (EGCG).
- Cinnamon Bark Powder (Cinnamomum verum) – standardized to 5 % cinnamaldehyde.
- Garcinia Cambogia Extract (Hydroxycitric Acid) – standardized to 60 % HCA.
- Chromium Picolinate – 200 µg per serving, intended to influence glucose metabolism.
- L‑Carnitine Tartrate – 500 mg per serving, proposed to support fatty‑acid transport.
- Glycine – 300 mg per serving, included for its role in protein synthesis and satiety signaling.
- Vitamin B‑Complex – a blend of thiamine, riboflavin, niacin, vitamin B6, and folic acid.
Each capsule contains 650 mg of the blended formulation. The inactive excipients include microcrystalline cellulose, magnesium stearate, and silicon dioxide, chosen for stability and ease of manufacturing.

Mechanism of Action
Thermogenic Effect
The green tea catechins and cinnamon components are believed to modestly elevate basal metabolic rate (BMR) through mild stimulation of the sympathetic nervous system. Catechins inhibit catechol-O-methyltransferase (COMT), prolonging the action of norepinephrine, while cinnamaldehyde enhances lipolysis in adipocytes.
Appetite Regulation
Chromium picolinate has been associated with improved insulin sensitivity, which may influence leptin and ghrelin pathways, thereby reducing hunger cues. Glycine, as a GABAergic amino acid, can exert a calming effect that may diminish the perception of cravings.
Fat Oxidation
L‑carnitine facilitates the transport of long‑chain fatty acids into mitochondria for β‑oxidation. In combination with catechins, which activate AMP‑activated protein kinase (AMPK), the supplement may enhance the rate at which stored fat is metabolized.
Carbohydrate Metabolism
The vitamin B‑complex serves as co‑enzymes in carbohydrate breakdown and energy production. Improved glucose utilization may reduce postprandial spikes, indirectly supporting weight management.
Clinical Studies
Pre‑Clinical Research
Animal studies conducted in rodent models demonstrated a statistically significant reduction in adipose tissue mass when animals were administered the CortiSlim blend at a dose equivalent to 5 mg/kg body weight. The observed decrease was attributed to increased thermogenesis and elevated expression of uncoupling protein‑1 (UCP‑1) in brown adipose tissue.
Human Pilot Trials
A randomized, double‑blind, placebo‑controlled pilot study involving 60 adults (age 25‑45) evaluated the efficacy of CortiSlim over a 12‑week period. Participants received either 2 capsules per day or placebo. Primary outcomes measured included body mass index (BMI), waist circumference, and fasting glucose. Results indicated a mean weight loss of 1.2 kg in the treatment group compared to 0.3 kg in the placebo group (p
Long‑Term Observational Data
Post‑marketing surveillance collected data from over 5,000 users who self‑reported weight changes. According to aggregated anonymized data, 42 % of participants reported a weight loss of at least 2 kg after 6 months of consistent use. However, the observational nature of the data limits causal inference, and no control group was present.
Safety Profile
Adverse event reports during clinical and post‑marketing studies were largely mild and included transient headaches, gastrointestinal discomfort, and mild flushing. No serious adverse events were attributed to the supplement. Nonetheless, regulatory agencies recommend caution for individuals with cardiovascular conditions or those taking anticoagulants, due to potential interactions with green tea catechins.
