Citrimax Plus
Also known as: HCA, Garcinia cambogia extract, Citrimax Plus, Citrimax, (-)-hydroxycitric acid, Hydroxycitric Acid
Overview
Hydroxycitric Acid (HCA) is a derivative of citric acid, primarily sourced from the rind of the Garcinia cambogia fruit, a tropical fruit native to Southeast Asia. Citrimax Plus is a branded supplement ingredient that contains HCA, standardized for its content. It is marketed as a weight loss aid and appetite suppressant, with claims of inhibiting fat synthesis and modulating metabolic pathways. Research on HCA's efficacy is moderate, with multiple randomized controlled trials (RCTs) and systematic reviews available. However, the evidence is inconsistent, showing only small, statistically significant effects that often lack clinical relevance, and concerns exist regarding study quality. It is classified as a weight loss/fat metabolism supplement.
Benefits
Systematic reviews and meta-analyses indicate a small, statistically significant weight loss effect of HCA-containing supplements compared to placebo, with an average difference of approximately -0.88 kg (95% CI: -1.75 to -0.01 kg). This effect, however, is considered borderline and often loses significance when only rigorous trials are included, suggesting limited clinical meaningfulness. Some reports suggest appetite suppression, but the evidence supporting this claim is weak and inconsistent. Most studies involve overweight or obese adults, and there is no strong evidence for specific population-specific benefits. The effect sizes are small, especially when compared to established weight loss medications like orlistat, which demonstrates a greater weight loss of around 2.9 kg over placebo. Benefits are typically observed in short-term studies (4–12 weeks), and long-term efficacy remains unestablished.
How it works
HCA is believed to exert its effects primarily by inhibiting the enzyme ATP citrate lyase. This enzyme plays a crucial role in the metabolic pathway that converts citrate into acetyl-CoA, which is a precursor for fatty acid synthesis (lipogenesis). By inhibiting ATP citrate lyase, HCA theoretically reduces the body's ability to form new fats. Additionally, HCA may influence appetite regulation, possibly through its interaction with serotonin pathways, though the evidence for this mechanism is limited. Oral bioavailability of HCA is moderate, and formulations like Citrimax Plus aim to optimize its absorption.
Side effects
Hydroxycitric Acid (HCA) is generally considered safe for short-term use, but comprehensive long-term safety data are limited. Common side effects, reported in some cases, include mild gastrointestinal symptoms. Less common side effects (1-5% frequency) may include headaches and dizziness. Rare but serious adverse events have been reported with Garcinia cambogia supplements, including cases of liver toxicity and acute pancreatitis, with some instances requiring liver transplantation. While these severe events are rare, they highlight potential risks. There are no well-documented drug interactions, but caution is advised for individuals with pre-existing liver disease or those taking hepatotoxic medications. HCA is contraindicated in individuals with liver disease, pregnancy, lactation, and potentially pre-existing pancreatitis. Safety in children, pregnant, or breastfeeding women has not been established.
Dosage
Typical daily dosages of HCA in studies range from 500 mg to 1500 mg, often divided into multiple doses throughout the day. Most randomized controlled trials (RCTs) have utilized doses between 1000 mg and 1500 mg of HCA per day. The minimum effective dose varies, and the maximum safe dose is not well-defined, as doses exceeding 1500 mg/day have not been thoroughly studied for safety. HCA is commonly taken 30–60 minutes before meals, as this timing is believed to maximize potential appetite suppression. Food intake may affect absorption, which is why pre-meal timing is often recommended. Citrimax Plus is formulated for enhanced bioavailability, and specific dosing instructions should follow the manufacturer's guidelines, generally aligning with the established HCA dosage ranges. No specific cofactors are established as required for its efficacy.
FAQs
Is Citrimax Plus effective for weight loss?
Research suggests a small, statistically significant but clinically marginal effect on weight loss. It's not considered a potent fat burner for substantial weight reduction.
Is Citrimax Plus safe to use?
It's generally safe for short-term use, but rare cases of serious liver toxicity and pancreatitis have been reported with Garcinia supplements, warranting caution.
When should I take Citrimax Plus?
It is typically recommended to take Citrimax Plus 30-60 minutes before meals to potentially aid in appetite suppression.
How long does it take to see results?
Short-term studies show effects within 4–12 weeks. Long-term efficacy and results beyond this period are not well established.
Are there any common misconceptions about Citrimax Plus?
A common misconception is that it's a powerful fat burner leading to significant weight loss. Evidence does not support large or clinically meaningful weight loss effects.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC3010674/ – This systematic review and meta-analysis of randomized controlled trials (RCTs) investigated the efficacy of Garcinia cambogia extract (HCA) for weight loss. It found a small, statistically significant weight loss effect (mean difference of -0.88 kg) compared to placebo, but noted that this effect was borderline and lost significance when low-quality trials were excluded. The study highlighted methodological limitations and heterogeneity among trials.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC7911601/ – This review focused on the risks and adverse events associated with Garcinia cambogia supplements. It compiled case reports and intervention studies, identifying rare but serious adverse events such as liver toxicity and pancreatitis. The review emphasized that while these events are uncommon, they are severe and necessitate caution, particularly for individuals with pre-existing conditions.
- https://onlinelibrary.wiley.com/doi/abs/10.1155/2011/509038 – This publication is an abstract for a systematic review and meta-analysis on the use of Garcinia extract (HCA) for weight loss. It concludes that while some studies show a small, statistically significant effect on weight loss, the clinical relevance is limited, and the quality of evidence is often poor, suggesting that the effect is not robust.
