Based on the latest research Burniva is the most effective weight loss and energy boosting supplement available. The three most powerful fat burners, Caffeine, Green Tea and L-Carnitine Fumarate, formulated in the right dosage and ratio work synergistically to maximize weight loss as well as an energy boosting formula.

Burniva provides 200mg of Caffeine which stimulates major mechanisms which aid fat loss by binding to fat cells and enhancing the removal of fat, and by inhibiting its storage in the fat cells. Caffeine also works to increase the burning of fat during exercise and can help increase muscle strength when taken before workouts. Burniva’s 500mg Green Tea dosage has a very high content of 95% catechins, which has been shown in various studies that it is far superior to other forms of green tea with a lower content of catechins, as used by rival products.  Catechins include epigallocatechin gallate (EGCG). EGCG is the main catechin responsible for the thermogenic (fat burning) effect of green tea. Clinical research has shown that L-Carnitine Fumarate is essential for fat burning and weight loss. New studies have also shown that 500mg of L-Carnitine Fumarate can significantly benefit weight loss programs. Even though L-Carnitine Fumarate is not a stimulant, it provides a gentle, natural energy boost by enhancing the body’s own ability to generate energy.

Various studies provide evidence that Caffeine stimulates the sympathetic nervous system and promote satiety, lipolysis and thermogenesis (1, 4). In an 8 week study by Belza et al (1) the control group receiving a supplement which included Caffeine and Catechins lost more body fat mass than the placebo group.

When Caffeine is combined with other ingredients it provides a synergistic effect, increases ergogenic potential and performance as shown in a study by Gonzalez et al. This study showed that a combination of ingredients including Caffeine significantly improved the training volume by delaying fatigue and improving the quality of exercise (3).
In a study by Wallman et al on 10 sedentary women showed that when Caffeine was ingested, VO2 Max and energy expenditure during a 15 min steady state exercise increased significantly. (9)

L-Carnitine plays a central role in fatty acid metabolism by transporting long-chain fatty acids into mitochondria for beta-oxidation. The problem with other L-Carnitine supplements is either a lower dosage is used or it isn’t combined with other proven ingredients therefore losing the synergistic effect that Burniva provides. A high amount of L-Carnitine, such as a daily dose of 1000mg as found in Burniva is needed to boost the energy output of mitochondria, which power our cells. Due to this benefit, Carnitine is being used in anti-aging formulas. Bruce N. Ames, PhD, a professor of biochemistry and molecular biology at the University of California, Berkeley swears by it as he thinks that the mitochondria decay is a major factor in aging.  Carnitine has also been proposed as a treatment for many conditions because it acts as an antioxidant. Antioxidants can neutralize free radicals and may reduce or help prevent some of the damage they cause.

Consumption of Caffeine and different teas have been proposed as strategies for weight loss and weight maintenance. Energy expenditure may increase by 4-5% and fat oxidation by 10-16% and can counteract the decrease in metabolic rate that is present during weight loss (6). Taken together Caffeine and Green Tea have the potential to produce significant effects on metabolic targets such as satiety, thermogenesis and fax oxidation (6).

The thermogenic properties and fat oxidation of Green Tea is beyond what can be explained by its Caffeine content per se (2). This can be explained by the Catechin content found in Green Tea.  A study by Make et al has shown that green tea extract containing a mixture of catechin polyphenols and caffeine significantly increased 24-h energy expenditure and reduced 24-h respiratory quotient, indicating an increase in the ratio of fat:carbohydrate oxidized (8).
It is not only the amount of Green tea extract that is important but the % of Catechins that it contains.  Other fat loss products, not only contain less Green Tea extract but lower % Catechins ranging from 15-55% as opposed to 95% found in Burniva. Burniva contains a daily dosage of 1000mg Green tea of which 900mg are Catechins!!  In a 12 week study in overweight males by Hase et al, consumption of a higher dose (483 mg/day) of tea catechins compared with a lower dose (118.5 mg/day) was associated with significantly greater reductions in body weight, body fat, and visceral fat area (5). In another study by Wolfram et al on 240 Japanese men and women with increased visceral adiposity, consumption of 583 mg/day of tea catechins was associated with significantly greater reductions in body weight, body fat and abdominal fat mass compared with a consumption of 96 mg/day (11). Similar results have been shown in other trials such as the study by Wang et al on 182 moderately overweight Chinese subjects. The subjects were divided into 4 different groups which were given different quantities of Catechins ranging from a low to an extra high content of Catechins. The group consuming the extra high content of Catechins (886mg/day)  showed the biggest reductions in waist circumference, body weight and body fat as opposed to the other groups (10).
