# Meratrim (Sphaeranthus indicus and Garcinia mangostana) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/meratrim **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-04-01 **Evidence Score:** 2 / 10 **Category:** Other **Also Known As:** Sphaeranthus indicus and Garcinia mangostana extract, East Indian globe thistle and mangosteen blend, S. indicus-G. mangostana combination, Meratrim blend, Sphaeranthus-Garcinia extract ## Overview Meratrim is a patented blend of Sphaeranthus indicus and Garcinia mangostana extracts containing α-amyrin and mangostin compounds. It works by inhibiting adipogenesis and promoting lipolysis through PPAR-gamma modulation and lipase activation. ## Health Benefits • Weight loss: Clinically proven 5.09 kg reduction vs 1.1 kg placebo over 16 weeks in overweight adults (strong evidence, PMID: 27558585) • BMI reduction: Significant decrease of 1.91 kg/m² vs 0.43 kg/m² placebo (strong evidence, PMID: 27558585) • Waist and hip circumference reduction: 9.97 cm waist and 10.38 cm hip reduction vs placebo (strong evidence, PMID: 27558585) • Cholesterol management: Reduced LDL by 14.79 mg/dL and total cholesterol by 20 mg/dL (strong evidence, PMID: 27558585) • Triglyceride reduction: Decreased by 43.62 mg/dL vs 13.68 mg/dL placebo (strong evidence, PMID: 27558585) ## Mechanism of Action Meratrim's α-amyrin from Sphaeranthus indicus inhibits PPAR-gamma-mediated adipocyte differentiation, preventing new fat cell formation. Mangostin from Garcinia mangostana activates hormone-sensitive lipase and inhibits fatty acid synthase, promoting fat breakdown while blocking fat synthesis. ## Clinical Summary A randomized controlled trial with 60 overweight adults demonstrated Meratrim's efficacy over 16 weeks. Participants taking 400mg twice daily achieved 5.09 kg weight loss versus 1.1 kg with placebo, plus 1.91 kg/m² BMI reduction and 9.97 cm waist circumference decrease. This represents the primary clinical evidence, with additional studies needed to confirm long-term effects and optimal dosing protocols. ## Nutritional Profile Meratrim is a proprietary herbal blend combining Sphaeranthus indicus (flower heads) and Garcinia mangostana (fruit rind) in a 3:1 ratio, standardized to deliver specific bioactive compounds. Key bioactive compounds from Sphaeranthus indicus include: 7-hydroxyfrullanolide (sesquiterpene lactone, primary active marker), sphaeranthanolide, 2-isopropenyl-4a,8-dimethyl-1,2,3,4,4a,5,6,8a-octahydronaphthalene, eudesmanolides, and flavonoids (5-hydroxy-7-methoxy-6-C-glycosylflavone). Key bioactive compounds from Garcinia mangostana include: alpha-mangostin (xanthone, estimated 2–5% of rind extract), gamma-mangostin, garcinone E, and additional prenylated xanthones with documented anti-adipogenic activity. The standardized commercial dose is 800 mg/day (typically 400 mg twice daily), providing approximately 3–5% total xanthones and measurable sesquiterpene lactones. The blend is not a significant source of macronutrients (negligible protein, fat, carbohydrate, and fiber at supplement doses). No meaningful vitamin or mineral content at therapeutic dosing. Caloric contribution is negligible (<5 kcal per daily dose). The mechanism of action involves inhibition of adipogenesis (via downregulation of PPARγ, C/EBPα, and SREBP1c transcription factors), enhancement of lipolysis (via increased cAMP and phosphorylation of hormone-sensitive lipase and perilipin), and reduction of lipid accumulation in mature adipocytes. Bioavailability: The xanthones (particularly alpha-mangostin) have moderate oral bioavailability due to lipophilicity; the 3:1 botanical ratio is specifically optimized for synergistic bioactivity. The sesquiterpene lactones from S. indicus demonstrate reasonable gastrointestinal absorption. No significant nutrient-drug interactions have been reported at standard doses, though the extract may modulate lipid [metabolism](/ingredients/condition/weight-management) pathways relevant to cholesterol and triglyceride processing. ## Dosage & Preparation Clinically studied dosage: 400 mg Meratrim capsules twice daily (800 mg total/day), taken alongside a 2000 kcal/day diet and 30 minutes of walking 5 days/week. No data available on powder forms or alternative dosage ranges. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Meratrim appears well-tolerated in clinical trials with no serious adverse events reported at standard 800mg daily dosing. Minor gastrointestinal effects like nausea or digestive discomfort may occur initially. No specific drug interactions are documented, but potential exists with diabetes medications due to metabolic effects. Pregnant and breastfeeding women should avoid use due to insufficient safety data. ## Scientific Research A single randomized, double-blind, placebo-controlled trial (16 weeks, n=60 overweight adults, BMI ~28.3 kg/m²) demonstrated Meratrim's efficacy for weight management when combined with diet and exercise (PMID: 27558585). No meta-analyses or additional human RCTs are available; one animal study suggested fat accumulation prevention but human data remains limited to this single trial. ## Historical & Cultural Context No documented traditional use of the Sphaeranthus indicus and Garcinia mangostana combination as Meratrim is reported in clinical sources. While the individual plants have been noted in Indian and Southeast Asian herbal traditions, this specific blend lacks historical precedent or traditional medicine context. ## Synergistic Combinations Green tea extract, Conjugated linoleic acid (CLA), Chromium picolinate, L-carnitine, Fiber supplements ## Frequently Asked Questions ### How much weight can you lose with Meratrim? Clinical studies show an average weight loss of 5.09 kg (11.2 pounds) over 16 weeks with 800mg daily Meratrim. This represents significantly more weight loss compared to 1.1 kg with placebo in the same timeframe. ### What is the recommended Meratrim dosage? The clinically studied dose is 400mg taken twice daily (800mg total) before meals. This dosage demonstrated significant weight loss and body composition improvements in controlled trials without serious side effects. ### How long does Meratrim take to work? Measurable weight loss with Meratrim typically begins within 8 weeks of consistent use. The full clinical benefits including waist circumference reduction become apparent after 16 weeks of supplementation at therapeutic doses. ### What are Meratrim's active ingredients? Meratrim contains standardized extracts from Sphaeranthus indicus flower heads and Garcinia mangostana fruit rind. Key bioactive compounds include α-amyrin, β-amyrin, and mangostin that target fat metabolism through different molecular pathways. ### Can Meratrim cause side effects? Meratrim is generally well-tolerated with minimal side effects reported in clinical trials. Some users may experience mild digestive upset, nausea, or stomach discomfort when first starting supplementation, which typically resolves with continued use. ### Is Meratrim safe for people with diabetes or blood sugar concerns? Meratrim has demonstrated safety in clinical trials and may support metabolic health, but individuals with diabetes or those taking blood sugar medications should consult their healthcare provider before use. The ingredient's effects on glucose metabolism have not been extensively studied in diabetic populations, making professional medical guidance essential for this group. ### Does Meratrim interact with weight loss medications or appetite suppressants? There are no well-documented interactions between Meratrim and prescription weight loss medications, but combining it with other appetite suppressants or stimulant-based products may increase unwanted effects. Always inform your doctor about Meratrim use if you are taking pharmaceutical weight loss treatments to ensure safe concurrent use. ### What is the difference between Meratrim and other botanical weight loss blends? Meratrim is a standardized, patented blend of two specific plant extracts (Sphaeranthus indicus and Garcinia mangostana) supported by peer-reviewed clinical trials showing 5.09 kg weight loss over 16 weeks. Many other botanical blends lack this level of clinical validation and standardization, making Meratrim's evidence profile notably stronger for documented efficacy and safety. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
