Subjects were also excluded if Carbohydrate metabolism and obesity had metabolic disorders, heart disease, hypertension, a known allergy to any ingredients in the supplement or placebo or had smoked cigarettes in the last six months.
Prior to being enrolled in the study, all subjects underwent a physical examination by a licensed physician, lead electrocardiogram, health history screen and provided written informed consent. This study utilized a randomized, placebo-controlled, parallel-group, double-blind design.
Subjects were matched according to sex and BMI prior to being randomized into placebo or METABO groups. Capsules were produced in accordance with current Good Manufacturing Practices cGMP in a United States Food and Drug Administration FDA registered facility. Prior to production, all raw materials were tested for purity and potency.
The study intervention included an 8-week diet and exercise program consisting of recreationally active men and women, randomly assigned to receive either a placebo or the manufacturer recommended dosage of their respective supplement two capsules with breakfast and two capsules with lunch.
Jeor equation[ 23 ] x an activity factor of 1. Each subject was given seven days of menus based off their daily allowance for calories. Each study participant was contacted on a weekly basis to assess compliance to diet and supplement protocol.
Every training session was supervised by a certified fitness professional and conducted at a single local facility to verify participation, and all subjects trained as one group.
The fitness professional used a participant attendance log to monitor training compliance. All subjects had measurements of their weight, BMI, waist and hip girths, body fat and lean mass taken at week 0 baselineweek 4 midpoint of the study and week 8 end of the study.
A member of the research staff contacted all subjects on a weekly basis to ensure compliance to the supplementation protocol, and pill counts were performed during mid and post testing.
Blood samples were drawn at week 0 and week 8 for standard assessment of clinical laboratory parameters i. comprehensive metabolic panel, lipid panel and at weeks 0, 4 and 8 for serum concentrations of adipocytokines adiponectin, resistin, leptin, tumor necrosis factor-α TNF-α and interleukin-6 IL Vital signs, including blood pressure and heart rate, were also recorded at weeks 0, 4 and 8.
All measurements were completed by the same researcher to minimize between-trial variation. Energy levels and food craving data were analyzed using a whole unit Likert-type scale[ 24 ]. All energy levels and food craving data were collected at weeks 0, 4 and 8.
All blood samples were taken in the morning at approximately the same time of day i. One aliquot was immediately analyzed for a item clinical chemistry profile Hitachi D, Roche Diagnostics, Germany by a certified clinical laboratory. This profile consisted of a comprehensive metabolic panel glucose, BUN, creatinine, sodium, potassium, chloride, carbon dioxide, calcium, total protein, albumin, globulin, total bilirubin, alkaline phosphatase, AST [SGOT], and ALT [SGPT] as well as a lipid profile total cholesterol, HDL-C, LDL-C, VLDL-C, triacylglycerols [TAG].
The second aliquot was stored at °C until later batch analysis for serum adipokines adiponectin, resistin, leptin, TNF-α, IL-6 via enzyme-linked immunosorbent assay. Adipokines were analyzed using a MAGPIX® Luminex Corporation, Austin, TX and customized commercially available magnetic bead panels Millipore Corporation, Billerica, MA.
Prior to each assay, the MAGPIX was calibrated using the MAGPIX Calibration Kit Millipore catalog and performance verified using the MAGPIX Performance Verification Kit Millipore catalog Each assay was run in one batch, therefore no inter-assay CV was determined.
Lean mass, percent body fat and trunk limb fat ratios were assessed using dual energy x-ray absorptiometry DEXA, GE Lunar, DPX Pro. All DEXA scans were performed by the same technician and analyzed via current manufacturer software enCORE version Female subjects were measured during the early follicular phase of their menstrual cycle, based on reported last menstrual period, to minimize effects of menstrual hormonal changes on dependent variables.
DEXA segments for the arms, legs, and trunk were subsequently obtained using standard anatomical landmarks. Percent fat was calculated by dividing fat mass by the total scanned mass. Quality control calibration procedures were performed prior to all scans using a calibration block provided by the manufacturer.
Prior to this study, we determined test-retest reliability for repeated measurements of lean mass, bone mineral content, and fat mass with this DEXA via intra-class correlation coefficients[ 25 ]. Waist girth defined as the narrowest part of the trunk between the bottom of the rib cage and the top of the pelvis and hip girth defined as the largest laterally projecting prominence of the pelvis or pelvic region from the waist to the thigh were measured in duplicate using standardized anthropometric procedures[ 26 ].
Seated, resting heart rate and blood pressure were measured in duplicate using an automated sphygmomanometer Omron HEM A baseline 3-d food record was completed for each subject after screening and enrollment, prior to randomization and intervention.
To verify dietary compliance, subjects completed 3-d food records which included two weekdays and one weekend day during baseline testing, week 4, and week 8. All food records were analyzed by a state-licensed, registered dietitian using commercially available software NutriBase IV Clinical Edition, AZ.
To enhance accuracy of the food records, all subjects received instruction during baseline testing on how to accurately estimate portion sizes. This counseling was reinforced during each visit to the laboratory. No other dietary supplements were allowed with the exception of standard strength multivitamins.
Safety and tolerability of the supplements were assessed through adverse event reports that were coded using the Medical Dictionary for Regulatory Activities MedDRA. Differences between groups from baseline to week 4 and baseline to week 8 were analyzed using analysis of covariance ANCOVA with the baseline scores employed as the covariate.
All analyses were verified to meet the homogeneity of regression assumption parallelism of ANCOVA. Non-normally distributed variables were log-transformed before analysis.
For descriptive purposes, raw values as well as the change scores week 4 minus baseline, week 8 minus baseline of all dependent variables are displayed. Statistical significance was accepted when the probability of a type 1 error was less than or equal to 0.
Data were analyzed using statistical software written using LabVIEW National Instruments, Austin TX programming software. However, a goal of 70 total subjects were be enrolled due to higher expected attrition from a study involving multiple independent variables including a prescribed diet, regular exercise, and supplement intervention.
Of the 70 subjects initially recruited, 25 were lost due to attrition i. Statistically significant decreases were observed from week 0 to week 8 for subjects who received METABO versus those who received placebo in body weight From week 0 to week 4 the mean differences in decreased waist girths for the subjects who received METABO versus those who received placebo were Similarly, the mean differences in decreased hip girths for the subjects who received METABO versus those who received placebo were The mean target daily dietary intake calculated using the Mifflin-St.
Jeor equation x 1. No differences were observed in energy consumption, or in absolute or relative amounts of dietary carbohydrate, protein or fat between METABO and placebo.
Subjects who received METABO also exhibited a statistically significant decrease in relative fats cravings compared to the placebo group No statistically significant differences between the two groups were observed for sweet, fast food fats, carbohydrates or healthy food cravings.
No serious adverse events occurred during this study and analyses of standard clinical chemistry panels of serum and plasma revealed no statistically significant abnormalities of clinical importance. There were no significant between group effects for any cardiovascular variable during the 8-week trial, and the changes within groups were modest and non-significant.
For resting systolic blood pressure, the placebo group went from Similarly, for resting diastolic blood pressure the placebo group dropped from For resting heart rate, the placebo group went from The incidence of non-serious adverse events e.
were transient and similar, with no significant differences between placebo and METABO. The results from this study demonstrate that as an adjunct to an 8-week diet and weight loss program, administration of METABO significantly decreases body weight, body fat mass, waist and hip girth, while increasing lean mass compared to the placebo.
Although a restricted diet can lead to weight loss, it is often accompanied by a loss of lean tissue[ 28 — 30 ], which can have deleterious metabolic consequences.

Raspberry ketones for increasing energy levels -
Raspberry Ketone is the primary aroma compound of red raspberries. This compound regulates adiponectin, a protein used by the body to regulate metabolism. Raspberry ketone causes the fat within your cells to get broken up more effectively, helping your body burn fat faster.
With Raspberry Ketone caps you can get the same effect by taking 1 capsule per day! FREE U. Sale Off. Product Highlights. Raspberry ketones have been shown to help promote lipolysis or the breakdown of fat cells.
It helps boost the immune system, provides ample energy, and detoxifies the body. Consuming raspberry ketones will result in your body being able to burn fat at a more effortless and faster rate due to its ability to mobilize fat cells. How to Take. Take capsules per day with meals.
Raspberry Ketones. Package 4 Week 1 Bottle 8 Week 2 Bottles 12 Week 3 Bottles. Add to Cart. The molecular structure of ketones is very similar to two other molecules, capsaicin — found in chili pepper — and the stimulant synephrine. Studies indicate that these molecules can boost metabolism.
Therefore, researchers speculated that raspberry ketones could have the same effect 7 , 8. In test-tube studies of fat cells in mice, raspberry ketones 9 :. Adiponectin is released by fat cells and may play a role in regulating metabolism and blood sugar levels.
People with normal weight have much higher levels of adiponectin than those who are overweight. Levels of this hormone increase when people lose weight 10 , Studies demonstrate that people with low adiponectin levels are at a higher risk of obesity, type 2 diabetes, fatty liver disease and even heart disease 12 , Therefore, it seems that raising adiponectin levels could help people lose weight and lower the risk of many diseases.
However, even if raspberry ketones raise adiponectin in isolated fat cells from mice, this does not mean that the same effect will occur in a living organism. Keep in mind that there are natural ways to increase adiponectin that do not involve raspberry ketones. Drinking coffee is also linked to higher levels 14 , 15 , Raspberry ketones have a similar molecular structure as two known fat-burning compounds.
While they show potential in test-tube studies, these results do not necessarily apply to humans. In one study, raspberry ketones were given to some mice fed a fattening diet In another study in 40 rats, raspberry ketones increased adiponectin levels and protected against fatty liver disease You would have to take times the recommended amount in order to reach the equivalent dose.
A dosage this severe is never advisable. Although some studies in rodents show that raspberry ketones can protect against weight gain and fatty liver disease, these studies used massive dosages — much higher than you would get with supplements.
The only human study that comes close used a combination of substances, including caffeine, raspberry ketones, garlic , capsaicin, ginger and synephrine In this eight-week study, people cut calories and exercised.
Those who took the supplement lost 7. However, the raspberry ketones may have had nothing to do with the observed weight loss. The caffeine or any of the other ingredients could be responsible. Comprehensive studies in humans are needed before the effects of raspberry ketones on weight can be fully assessed.
There is no evidence that raspberry ketone supplements can cause weight loss in humans. More research is needed. When administered topically as part of a cream, raspberry ketones appear to increase hair growth in people with hair loss. It may also improve skin elasticity in healthy women However, this study was small and had a number of flaws.
More studies need to confirm these effects before any claims can be made One small study proposes that raspberry ketones, administered topically, can increase hair growth and improve skin elasticity.
While there are anecdotal reports of jitteriness, rapid heartbeat and increased blood pressure, there are no studies to support this. Without human studies on raspberry ketones, there is no good data on side effects or a science-backed recommended dosage.
While they seem to work in test animals fed extreme doses, this has no relevance to the doses commonly recommended in humans. Lasting, beneficial changes in your lifestyle are much more likely to have an impact on your weight than raspberry ketones.

Raspberry ketones for increasing energy levels -
Similarly, for resting diastolic blood pressure the placebo group dropped from For resting heart rate, the placebo group went from The incidence of non-serious adverse events e.
were transient and similar, with no significant differences between placebo and METABO. The results from this study demonstrate that as an adjunct to an 8-week diet and weight loss program, administration of METABO significantly decreases body weight, body fat mass, waist and hip girth, while increasing lean mass compared to the placebo.
Although a restricted diet can lead to weight loss, it is often accompanied by a loss of lean tissue[ 28 — 30 ], which can have deleterious metabolic consequences. Because of this, it is important to achieve weight loss with a high ratio of fat to lean mass loss that is essential for both short-term efficacy and long-term metabolic health and body weight maintenance[ 31 , 32 ].
In this study, overweight subjects who received METABO achieved significantly greater improvements in their lean mass-to-fat mass ratio. Future studies should follow subjects during a washout period to determine if this effect helps maintain long-term weight control i.
minimize weight re-gain. Additionally, a future investigation should include a METABO only group with dietary control and no structured exercise program to explore the role of diet with METABO alone on body composition and metabolic outcomes.
Future studies may attempt to explore this observation further with studies designed to look for differences in these important metabolic and biochemical markers as primary outcome measures.
Another important finding in our study relates to the observed differences in adipokine concentrations in the METABO group, although most of these did not achieve statistical significance.
For example, we observed a trend for decreased serum resistin concentrations in subjects who received METABO compared to placebo at week 4, but not week 8. High serum resistin concentrations have been found in obese individuals and have been linked to insulin resistance, hence the trend for decreased resistin levels in METABO is an intriguing finding that requires further investigation in a future study[ 33 ].
The current study may have been underpowered to detect significant differences in serum adiponectin, given that fat loss occurred in both groups as a result of caloric restriction and a consistent exercise program.
In addition, trends for maintaining elevated serum leptin from week 0 to week 4 were observed in subjects who received METABO compared to placebo. Leptin acts on receptors in the hypothalamus to regulate appetite, energy expenditure, sympathetic tone and neuroendocrine function, and circulating levels have been shown to decline in response to caloric restriction or negative energy balance[ 34 ].
Leptin deficiency has been shown to promote hunger and food seeking behaviour, in addition to reduced metabolic rate in humans[ 35 ]. Collectively, the trend for resistin and significant change in leptin may help to partly explain the effects of METABO on body composition.
The combination of ingredients with potentially complementary and interactive mechanisms of action may account for the favorable changes observed in many of the clinical endpoints in the METABO group.
Razberi-K® contains Raspberry ketone 4- 4-hydroxyphenyl butanone , which is a naturally occurring phenolic compound in red raspberry Rubus ideas that has been shown to enhance norepinephrine-induced lipolysis in adipocytes, prevent high-fat diet-induced body weight gain in mice, and increase adiponectin gene expression and secretion in adipocytes in culture[ 12 , 13 ].
Moreover, Wang et al. demonstrated anti-inflammatory benefits, improved antioxidant capacity, and enhanced leptin and insulin sensitivity in Sprague-Dawly rats using a high-fat diet induced nonalcoholic steatohepatitis NASH model[ 36 ].
From the limited preclinical literature, it appears that raspberry ketones require norepinephrine for maximizing their hormone-sensitive lipolytic action. Capsimax® is a concentrated capsicum extract found in an encapsulated beadlet form to decrease gastric irritation.
Advantra Z® is an ingredient extracted from the Citrus aurantium traditional Chinese herb known as zhi-shi and standardized for the bioactive alkaloid p-synephrine. Other alkaloids are present in the extract including: octopamine, hordenine, and n-methyltyramine.
Taken together, the bioactive amines found in Advantra Z® have been shown to increase thermogenesis, and there is cell and tissue culture evidence to suggest lipolysis is accelerated via a β3 adrenergic receptor pathway[ 40 ]. A recent systematic review of human clinical studies involving Citrus aurantium with its primary p-synephrine alkaloid alone or in combination with other ingredients revealed reliable increases in resting metabolic rate of between 2.
Caffeine is regarded as one of the most commonly consumed methylxanthine alkaloids known to act as an adenosine receptor antagonist and phosphodiesterase inhibitor. As such, the presence of caffeine may have contributed to amplifying the beta-adrenergic and lipolytic effects of the METABO formulation.
Despite being on a calorie-reduced diet, subjects in this study reported feeling improved energy and decrease in cravings for energy-dense, fatty foods. Previous studies have indicated that food cravings are significantly related to food intake with specific cravings correlating with types of food consumed[ 24 ] and a high-fat diet is a strong risk factor for the development of obesity and metabolic syndrome, as a result of increased energy density and overall caloric intake[ 41 ].
Caffeine, in isolation or in combination with other bioactive nutritional compounds, has also been shown in multiple human clinical trials to increase the perception of energy, blunt appetite, and improve measures of mood, alertness, attention, and concentration[ 14 , 42 , 43 ]. Although subject demographics were similar between groups, there was greater attrition of the placebo group relative to METABO.
It has been reported that decreased levels of mental and physical energy and increased cravings for energy-dense foods can diminish dietary and exercise adherence during outpatient weight loss programs[ 46 , 47 ].
A notable finding in this regard is that, compared to the placebo group, the METABO group experienced a significant increase in their energy levels and decreased cravings for energy-dense foods.
Future studies may examine if METABO improves adherence to a comprehensive diet and exercise weight loss program. Gender differences were not explored in our study, but future investigations are currently underway in an attempt to answer this question. The mean target caloric intake for the METABO group using the Mifflin-St.
Jeor equation multiplied by an activity factor of 1. However, three-day food records are notorious for recall bias and an underestimation of actual energy consumption[ 48 ].
Jeor equation. The obese and overweight state is characterized by chronic, low-grade systemic inflammation as a result of the expanded white adipose tissue compartment, particularly the visceral adipose depot.
Adipose tissue from obese individuals is known to be an important endocrine organ capable of contributing to insulin resistance, persistent inflammation, and metabolic and vascular dysfunction via the perturbed adipokine secretion profile[ 34 ].
The collective action of garlic extract standardized for organosulfur compounds, ginger extract standardized for gingerols and shogaols, biotin and chromium in METABO may contribute to antiadipogenic, anti-inflammatory actions in conjunction with metabolic health benefits[ 20 , 21 , 36 , 37 , 49 — 51 ].
The bioactive compounds in garlic, ginger, and raspberry in addition to biotin and chromium have been suggested to modulate high-leverage metabolic pathways with nutrigenomic signaling, including: NF-kB, PPAR-γ, PPAR-α, orexigens, and aforementioned adipocytokines. It is conceivable that although increased sympathomimetic drive, lipolysis and thermogenesis contributed to the positive outcomes in body composition, the interaction of reduced dietary energy intake with exercise and METABO lead to further improvements in the adipokine profile that facilitated improvements in serum triacylglycerol, selective fat loss, skeletal muscle retention and abdominal girth reduction.
It would be helpful for future studies to explore the influence of METABO on the systemic adipokine profile to clarify if this is one potential mechanism. In recent years, there have been numerous natural products being marketed and sold that claim to contain the right combination of vitamins, herbs and foods that can help with weight loss.
However, very few of these products undergo finished product-specific research demonstrating their efficacy and safety. In the current study, as an adjunct to an 8-week diet and weight loss program, METABO administration augmented beneficial changes in body composition and anthropometric variables hip and waist girth in overweight men and women, and led to additional benefits on energy levels and food cravings.
The placebo group had noticeable beneficial changes in body fat and non-significant improvements in certain metabolic variables as a result of diet and exercise alone, albeit these changes were less robust than in METABO group. METABO was safe and well-tolerated in all subjects, no serious adverse events were recorded, nor were differences in systemic hemodynamics or clinical blood chemistries observed between the two groups.
Further studies are required to clarify the mechanisms by which METABO exerts its weight loss effects and its possible role in regulating adipokine concentrations.

A study published in the Journal of Medical Food found that raspberry ketone treatment, after a high-fat diet, can protect rats against nonalcoholic steatohepatitis, which is liver inflammation caused by a buildup of fat in the liver. Researchers reported that raspberry ketones had a dual effect of liver protection and fat reduction in the tested rats.
The issue with these studies involving rodents is that the doses are very high; in fact, the equivalent dose in humans is to milligrams a day, which is over times greater than the average daily intake of raspberry ketones!
This is a worrisome dosage, especially when compared to other fat-burning supplements that are on the market today. So although this study suggests that raspberry ketones may help to reduce liver inflammation, more studies need to be done on humans using the appropriate dosage.
A study found that raspberry ketones may have a therapeutic role in controlling hyperlipidemia and insulin resistance among obese rats. Again, this is an animal study and the ketone doses were — milligrams per kilogram of body weight, which would be a very high dose for humans.
The study does suggest, however, that raspberry ketones contribute to the upregulation of AQP7 expression, which is protein that plays a role in metabolic function. Like most of the potential raspberry ketone benefits, more research is needed on this to indicate whether or not ketones are effective for normalizing cholesterol levels and insulin resistance in humans.
A study on mice found that when 0. When researchers tested whether or not raspberry ketones work as a natural treatment for thinning hair on humans, they also found positive results.
When raspberry ketone was applied topically to the scalp, it promoted hair growth in 50 percent of humans with alopecia at five months after applications. The same researchers in Japan that reported the efficacy of raspberry ketones for hair growth evaluated its ability to improve skin elasticity in humans.
They found that when 0. This was only tested on five women, but it is a bit of promising evidence offered on raspberry ketones involving humans. Traditionally, ketones found in red raspberries were used to prevent high cholesterol, diabetes and even liver cancer. Raspberries were consumed for their ketones before supplements with much higher doses were available.
Raspberries were also eaten for their nutritional value. Raspberry nutrition is quite impressive, boasting powerful antioxidants and nutrients like vitamin C , manganese, vitamin K and magnesium. Consuming raspberries is known to help reduce inflammation, boost heart health, ease arthritic pain and fight aging.
Raspberry ketones supplements are available in capsule form, and they are widely available online and in vitamin stores. Raspberry ketone supplement dosage ranges from —1, milligrams, once or twice daily.
Naturally, you only eat about 0. Before you choose to use high doses of raspberry ketone supplements, it would be best to have medical research involving humans that supports the biological effects first.
There is no scientific research that evaluates the side effects of these doses on humans or the impact that they have on human cells and organs. You can get ketones in your diet by eating berries including raspberries, blackberries and cranberries and fruits like kiwi, apples, grapes and peaches.
Raspberry ketones are said to increase measures of metabolism and affect a metabolism-regulating hormone in the body called adiponectin.
Adiponectin is involved in regulating glucose levels and breaking down fatty acids. Some supplement companies are claiming that raspberry ketones are a great way to increase adiponectin levels, but guess what?
You can boost this fat-burning hormone naturally with foods like avocados, nuts and olive oil. Drinking coffee can also increase adiponectin levels and so will exercising. Some people get confused about raspberry ketones playing a role in ketosis and being part of the keto diet.
When purchasing Raspberry Ketone capsules, be mindful of the quality of ingredients, manufacturing standards, and customer reviews.
