Improving the Efficacy of Capsinoids as a Thermogenic Adjunct in Clinical Weight Management

Clinical research is clarifying the mechanisms by which capsinoids – thermogenic compounds found in certain strains of chili peppers – can regulate fat metabolism and help overweight individuals reduce abdominal fat and improve their health. In this white paper, you will see research that shows how capsinoids deliver the thermogenic punch of capsaicin without the pungency or the potential adverse effects.

Effects of dihydrocapsiate on adaptive and diet-induced thermogenesis with a high protein very low calorie diet: a randomized control trial

This study was designed to examine the effects of dihydrocapsiate on both adaptive thermogenesis as the result of caloric restriction with high protein very low calorie diet and to determine whether dihydrocapsiate would increase post-prandial energy expenditure.

Nonpungent capsaicin analogs (capsinoids) increase energy expenditure through the activation of brown adipose tissue in humans

This placebo-controlled research study conducted on humans indicates the involvement of brown adipose tissue in capsinoid-induced energy expenditure in men and contributes to a better understanding of the underlying mechanisms of the anti-obesity effects of capsinoids.

Effects of novel capsinoid treatment on fatness and energy metabolism in humans: possible pharmacogenetic implications

This study, published in the American Journal of Clinical Nutrition, was designed to explore the safety and efficacy of capsinoids taken orally for weight loss, fat loss and change in metabolism and to examine whether candidate genes are predictors of capsinoids response.

Upregulation of uncoupling proteins by oral administration of capsiate, a nonpungent capsaicin analog

In this study published in the Journal of Applied Physiology, researchers report that a two-week treatment of capsiate increased metabolic rate and promoted fat oxidation at rest.

Effects of CH-19 Sweet, a Non-Pungent Cultivar of Red Pepper, in Decreasing the Body Weight and Suppressing Body Fat Accumulation by Sympathetic Nerve Action in Humans

In this study, researchers proposed that the repeated intake of Ch-19 Sweet, a red pepper containing capsiate, reduced body weight and suppressed body fat accumulation by sympathetic nervous activation in human subjects. Results suggest that the repeated intake of CH-19 Sweet for two weeks suppressed body fat accumulation, especially visceral fat accumulation and reduced body weight by sympathetic nervous system (SNS) activation. It has been suggested that CH-19 Sweet and its ingredient capsiate are useful for suppression of body fat accumulation because they deliver the same physiological effects as capsaicin without the pungency.

Novel Capsaicinoid-like Substances, Capsiate and Dihydrocapsiate, from the Fruits of a Nonpungent Cultivar, CH-19 Sweet, of Pepper (Capsicum annuum L.)

Capsicum species, peppers, are important plants and have been used worldwide as foods, spices, and medicines. The major pungent components in fruits of Capsicum plants are capsaicin, (E)-N-[(4-hydroxy-3-methoxyphenyl)methyl]-8-methyl-6-nonenamide, and dihydrocapsaicin. More than 12 other capsaicinoids have been found as minor components. Capsaicin has many bioactivities but its usage as a food additive or a drug is limited by its strong pungency and nociceptive activity. Watanabe et al. (1994) reported that several nonpungent capsaicinoids enhance adrenal catecholamine secretion as well as capsaicin. These nonpungent capsaicinoids are interesting from the viewpoint of wide application to foods and drugs. It has been reported that the fruits of a nonpungent cultivar of pepper, named CH-19 Sweet, contain only a small amount of capsaicinoids but considerable capsaicinoid-like substances (CLSs). This study was designed to characterize the structure of the CLSs found in CH-19, resulting in the identification of two novel CLSs: capsiate and dihydrocapsiate.

The Effects of Capsaicin and Capsiate on Energy Balance - Critical Review and Meta-analyses of Studies in Humans

This paper critically evaluates current knowledge on the thermogenic and appetitive effects of capsaicin and capsiate from foods and in supplemental form. Meta-analyses were performed on thermogenic outcomes, with a systematic review conducted for both thermogenic and appetitive outcomes.

Effects of capsinoid ingestion on energy expenditure and lipid oxidation at rest and during exercise

In this study, researchers looked to determine how ingestion of capsinoids affected energy expenditure, lipid oxidation and blood metabolites at rest and during moderate exercise. Study findings show that ingesting 10mg of capsinoids increased adrenergic exercise and energy expenditure and further suggest its potential role in weight management supplementation.

CH-19 Sweet, a Non-Pungent Cultivar of Red Pepper, Increased Body Temperature and Oxygen Consumption in Humans

Researchers measured body temperature and oxygen consumption in humans to determine whether CH-19 Sweet, a non-pungent cultivar of red pepper that contains Capsiate, has a thermogenic effect in humans. Study findings demonstrated that body temperature and oxygen consumption were increased by a single intake of CH-19 Sweet, suggesting that CH-19 Sweet increases thermogenesis and energy expenditure and that daily intake of this pepper may be used as a therapeutic tool for obesity.

TRPV1 activation and induction of nociceptive response by a non-pungent capsaicin-like compound, capsiate

In this study, researchers endeavored to learn the mechanisms underlying the non-pungency of capsiate by investigating whether capsiate activates the cloned capsaicin receptor TRPV1. Study results showed that capsiate was found to activate TRPV1 with a similar potency as capsaicin. In addition, capsiate did not induce any significant responses when applied to the skin surface, eye or oral cavity of mice, suggesting that capsiate requires direct access to nerve endings to exhibit its effects.

Enhanced Energy Expenditure and Fat Oxidation in Humans with High BMI Scores by the Ingestion of Novel and Non-Pungent Capsaicin Analogues (Capsinoids)

In this study, obese or obese-prone subjects with BMI >25 were recruited and assigned to three groups in a randomized, double-blind study over a four-week period. Test samples of oil extracted from CH-19 Sweet peppers containing capsinoids were administered and oxygen consumption (VO2) and resting energy expenditure (REE) were measured. Study results showed that not only did VO2 increase significantly in subjects exposed to capsinoids, but REE and fat oxidation tended to increase as well, implying that a capsinoid-induced change is an important factor leading to possible weight reduction.

Effects of CH-19 Sweet, a Non-Pungent Cultivar of Red Pepper, on Sympathetic Nervous Activity, Body Temperature, Heart Rate, and Blood Pressure in Humans

Researchers investigated the changes in autonomic nervous activity, body temperature, blood pressure and heart rate after intake of CH-19 Sweet and of hot red pepper to elucidate the mechanisms of diet-induced thermogenesis due to CH-19 Sweet. Study results indicated that CH-19 Sweet, a non-pungent cultivar of red pepper that contains capsiate, activates the sympathetic nervous system and accelerates diet-induced thermogenesis simultaneously without affecting blood pressure or heart rate.
