Capsorb
Also known as: Capsorb, non-pungent capsaicin analogs, capsiate, dihydrocapsiate, nordihydrocapsiate, Capsinoids
Overview
Capsinoids are naturally occurring compounds found in certain varieties of chili peppers, structurally similar to capsaicin but lacking its characteristic pungency. Capsorb is a branded commercial form of capsinoids designed for dietary supplementation. These compounds are primarily used to support weight management, improve body composition, and potentially modulate blood pressure. They are characterized by their thermogenic and metabolically active properties, thought to activate TRPV1 receptors without causing the irritation associated with capsaicin. Research on capsinoids is moderately mature, with several randomized controlled trials and meta-analyses indicating their potential benefits, particularly in overweight and obese adults. The evidence suggests modest but consistent effects on body composition and diastolic blood pressure.
Benefits
Capsinoid supplementation has demonstrated several evidence-based benefits. A 2022 systematic review and dose-response meta-analysis of randomized controlled trials (n≥30 per group) found that capsinoids significantly reduced body mass index (BMI), body weight, and fat mass, with dose-dependent effects. These improvements are considered small to moderate but consistent, primarily observed in overweight and obese adults. Another meta-analysis indicated that capsinoids did not significantly reduce systolic blood pressure (SBP) but showed a small, significant reduction in diastolic blood pressure (DBP) by approximately 1.9 mmHg. While modest, this reduction could be clinically relevant in hypertensive populations. Secondary effects include increased energy expenditure and fat oxidation, contributing to weight management. The time course for these benefits typically requires at least 12 weeks of consistent supplementation. Effects on athletic performance are not well-supported by current research.
How it works
Capsinoids exert their effects primarily by activating the transient receptor potential vanilloid 1 (TRPV1) channels, similar to capsaicin. This activation, however, occurs without the pungency-related irritation. Upon activation, TRPV1 channels trigger an increase in sympathetic nervous system activity, leading to enhanced thermogenesis (heat production) and increased fat oxidation. Capsinoids interact with the body's systems by acting on the gastrointestinal tract and peripheral sensory neurons, stimulating metabolism without causing oral or gastric discomfort. Their lower pungency allows for sufficient absorption in the gut, enabling systemic metabolic effects. The primary molecular target is the TRPV1 receptor, which plays a crucial role in energy metabolism and body temperature regulation.
Side effects
Capsinoids are generally regarded as safe with a favorable safety profile and minimal adverse effects reported in clinical trials. Common side effects are rare, with some mild gastrointestinal discomfort occasionally noted, but this is uncommon. Uncommon and rare side effects are not consistently reported, and no serious adverse events have been identified in meta-analyses. Regarding drug interactions, no well-documented interactions exist; however, caution is advised when co-administering with antihypertensive medications due to the potential for additive blood pressure-lowering effects. Contraindications are not firmly established, but individuals with known sensitivity to capsaicin or related compounds should exercise caution. Data on special populations such as pregnant or lactating women, children, or individuals with severe cardiovascular disease are limited, and use in these groups should be approached with prudence.
Dosage
Meta-analyses suggest that doses of capsinoids as low as 2 mg per day can be effective in reducing diastolic blood pressure and improving body composition. Optimal dosage ranges observed in studies typically fall between 3 mg and 12 mg of capsinoids daily, often delivered through standardized formulations like Capsorb. There is no established maximum safe dose; clinical trials have utilized doses up to 12 mg/day without reporting safety concerns. For measurable effects, daily supplementation for at least 12 weeks is recommended. Capsorb is a standardized capsinoid extract designed for oral intake. For best absorption, it is generally recommended to take capsinoids with meals, and no specific cofactors are required to enhance their bioavailability.
FAQs
Is Capsorb safe for long-term use?
Current evidence supports the safety of capsinoids for at least 12 weeks. While longer-term data are limited, no significant safety concerns have emerged from existing research.
How soon can benefits be expected?
Benefits related to body composition and blood pressure typically become noticeable after 8-12 weeks of consistent daily supplementation.
Does Capsorb cause spicy or burning sensations?
No, capsinoids are non-pungent compounds and do not produce the burning or spicy sensation commonly associated with capsaicin.
Can Capsorb replace weight loss medications?
Capsinoids can support weight management efforts but should not be considered a replacement for clinically indicated weight loss medications or treatments.

- https://pubmed.ncbi.nlm.nih.gov/33129596/ – This meta-analysis by Azimi et al. (2020) investigated the effect of capsinoids on blood pressure. It concluded that capsinoids did not significantly reduce systolic blood pressure but showed a small, significant reduction in diastolic blood pressure by approximately 1.9 mmHg. The study highlighted the modest but potentially clinically relevant effect on DBP.
- https://pubmed.ncbi.nlm.nih.gov/36513480/ – Sheikhhossein et al. (2022) conducted a systematic review and dose-response meta-analysis of RCTs on capsinoid supplementation. Their findings indicated that capsinoids significantly reduced BMI, body weight, and fat mass, demonstrating a dose-response relationship. This high-quality meta-analysis supports the role of capsinoids in body composition improvement.

(2025) evaluated various supplements for athletic performance in soccer players. While not directly focused on capsinoids, it suggests that capsinoids are not among the most effective supplements for athletic performance, indicating limited data or efficacy in this specific context.
