Super CitriMax (Garcinia cambogia extract)
Super CitriMax is a patented, calcium-potassium salt form of hydroxycitric acid (HCA) derived from Garcinia cambogia fruit rind, standardized to 60% HCA. Its primary mechanism involves competitive inhibition of ATP-citrate lyase, the cytosolic enzyme responsible for converting citrate into acetyl-CoA, a key precursor for de novo lipogenesis and cholesterol synthesis.

Origin & History
Super CitriMax is a branded extract derived from the dried rind of Garcinia cambogia fruit, native to Southeastern Asia and India. It is standardized to contain 60% (-)-hydroxycitric acid (HCA) as a novel calcium/potassium salt (HCA-SX) for improved solubility and bioavailability compared to standard calcium-based HCA.
Historical & Cultural Context
The dried rind of Garcinia cambogia has been used for centuries in Southeast Asia, particularly India, as a food preservative, flavoring agent in curries, and carminative to relieve flatulence. This longstanding culinary and medicinal use predates modern extraction methods.
Health Benefits
• May inhibit fat synthesis by blocking ATP-citrate lyase enzyme (supported by animal studies, human evidence not detailed) • Could reduce food intake and appetite (demonstrated in animal models, human clinical data lacking) • Potentially supports carbohydrate metabolism by redirecting nutrients to glycogen storage (mechanism-based, clinical evidence not provided) • May enhance fat burning when combined with chromium (theoretical based on mechanism, specific trials not cited) • Possibly supports healthy lipid levels through inhibition of acetyl-CoA formation (proposed mechanism, human studies not detailed)
How It Works
Super CitriMax's active compound, hydroxycitric acid (HCA), competitively inhibits ATP-citrate lyase, blocking the conversion of citrate to acetyl-CoA and oxaloacetate in the cytoplasm, thereby reducing available substrate for fatty acid and cholesterol biosynthesis. This metabolic shift increases hepatic glycogen synthesis, which is theorized to stimulate vagal afferent signaling to the hypothalamus, suppressing appetite via serotonergic pathways and elevating serotonin availability. The calcium-potassium salt formulation in Super CitriMax is specifically engineered to enhance HCA bioavailability compared to standard calcium-only HCA salts.
Scientific Research
While one review (PMID: 15234082) summarizes extensive animal studies showing HCA inhibits fat synthesis and reduces food intake, specific human clinical trial data is notably absent from available research. A randomized, double-blind study on Super CitriMax Plus for lean body composition is mentioned but lacks details on design, sample size, or results.
Clinical Summary
A randomized, double-blind, placebo-controlled trial by Preuss et al. (2004) found that 2,800 mg/day of Super CitriMax over 8 weeks produced a mean weight loss of 5.4% and a significant reduction in BMI compared to placebo in 60 overweight adults. A separate 8-week study with 30 participants noted reductions in food intake and serum leptin levels alongside modest fat mass decreases at doses of 2,400 mg/day. However, a well-cited 12-week randomized trial by Heymsfield et al. (1998) using standard HCA (not the Super CitriMax formulation) found no significant weight loss versus placebo in 135 subjects, highlighting that formulation-specific bioavailability matters. Overall, evidence is preliminary and methodologically limited by small sample sizes, short durations, and industry funding, warranting cautious interpretation.
Nutritional Profile
Super CitriMax is a patented, calcium-potassium salt form of hydroxycitric acid (HCA) extracted from the rind of Garcinia cambogia fruit. The standardized extract typically contains 60% (-)-hydroxycitric acid (HCA) by weight, which is the primary bioactive compound. Key compositional details: • **Hydroxycitric acid (HCA):** ~600 mg per 1,000 mg of extract; present as the calcium-potassium salt (Ca/K-HCA), which significantly improves solubility and bioavailability compared to the free acid or calcium-only salt forms. Bioavailability of the Ca/K salt form is estimated to be substantially higher (up to 2–3× greater absorption) than earlier lactone or calcium-salt preparations that were poorly soluble at physiological pH. • **Calcium:** approximately 10–16% by weight (~100–160 mg per 1,000 mg extract), contributed by the mineral salt complex. • **Potassium:** approximately 6–10% by weight (~60–100 mg per 1,000 mg extract), contributed by the mineral salt complex. • **Garcinol and xanthones:** trace amounts of polyphenolic compounds naturally present in Garcinia cambogia rind, including garcinol (a polyisoprenylated benzophenone with antioxidant and anti-inflammatory properties) and minor xanthones; concentrations are low and not standardized in the commercial extract. • **Fiber and macronutrients:** negligible protein, fat, and dietary fiber content per typical supplemental dose (1,500–4,500 mg/day of extract). Caloric contribution is essentially zero. • **No significant vitamins** (A, C, D, E, B-complex) are present in meaningful quantities. • **Mechanism-relevant note:** HCA is a structural analog of citric acid and competitively inhibits ATP-citrate lyase (EC 4.1.3.8), the enzyme that converts citrate to oxaloacetate and acetyl-CoA in the cytoplasm, thereby potentially reducing de novo lipogenesis. The Ca/K salt form maintains HCA in the open-chain, biologically active configuration rather than converting to the inactive lactone form, which is a key bioavailability advantage of the Super CitriMax formulation over generic Garcinia cambogia extracts.
Preparation & Dosage
Clinically studied forms use 1,000-1,500 mg Super CitriMax per serving (providing 600-900 mg HCA), often with 200 mcg chromium polynicotinate, taken as 2-3 capsules 1 hour before meals, 2-3 times daily (total daily: up to 3,000-6,000 mg extract). Consult a healthcare provider before starting any new supplement.
Synergy & Pairings
Chromium polynicotinate, Gymnema sylvestre, Green tea extract, L-carnitine, Conjugated linoleic acid
Safety & Interactions
Super CitriMax is generally well tolerated at clinically studied doses of 2,400–2,800 mg/day, with most reported side effects being mild and gastrointestinal in nature, including nausea, digestive discomfort, and headache. Rare but serious hepatotoxicity cases have been reported with Garcinia cambogia products broadly, though causality has not been definitively established for isolated HCA formulations. HCA may interact with antidiabetic medications and insulin by enhancing glycogen synthesis and potentially lowering blood glucose, necessitating monitoring in diabetic patients. Super CitriMax is not recommended during pregnancy or lactation due to insufficient safety data, and individuals on statins should exercise caution given HCA's potential to alter cholesterol biosynthesis pathways.
