Vintage Burn Fat Burner Ingredients

Green Tea Extract 330mg - Green Tea Leaf Extract is typically dosed around 500mg in better fat burners. It does have some mild to moderate impact on weight loss when used in conjunction with dieting. However, the supplement won't do anything by itself, it simply is an additional extra.

Green Coffee Bean Extract 270mg - The evidence from the latest meta analysis (a study which reviews all of the studies, removing the animal trials and those that weren't properly controlled, or were clearly biased) seems to show that green coffee bean extract does in fact promote an improvement in weight loss. [1] It's just not as dramatic as a lot of fat burners claim it to be. It won't burn fat by itself, it just leads to increased weight loss when used alongside diet and exercise.

Raspberry Ketones 200mg - These basically rose to fame of the back of a rat study and being televised as a miracle pill, later studies have since debunked them, there's pretty much no scientific backing for raspberry ketones. [2]

Olive Leaf Extract 60mg - There's only really animal studies to back this ingredient, it's also likely to be too low of a dosage even if it dose work for humans as this is barely larger than the effective thermogenic fat burner dosage for rats.

Caffeine 150mg - We've said caffeine belongs in a good fat burner. It helps you lose weight and arguably preserve muscle mass through keeping you moving in a caloric deficit. That's how you preserve muscle whilst dieting, continuing to use it so that your body is more inclined to use the stored fats.

Bacopa Leaf Extract 30mg - Bacopa has a lot of mood elevating effects, which in theory suggest may reduce cravings (other proven supplements like 5htp work through this method), but it has not been directly tested. however the dose is 300mg for it to be effective. [3]

Garcinia Fruit Extract 100mg - This one does work, but seems to make an improvement of about 2lbs over a 12 week course when being used alongside diet and exercise [4], this is a small improvement, and if this were a bolt on ingredient to an otherwise well designed fat burning supplement, then we'd score old school vintage burn a lot more highly. As it stands we're not doing to well, so garcinia fruit extract is not a good inclusion.

Chrysin 100mg - There's one correlation study based on how much chrysin is in your diet [5], it's not great, not really much in the way of solid research. The only other backing is some animal studies in relation to brown adipose vs white adipose tissue (types of fat cells) and most of these are not good studies that are designed to sell products more than help you lose weight.

Forskohlii Root Extract 60mg - Typically seen as a testosterone raising ingredient rather than something that's in good weight loss supplements, most results have suggested that corleus forskohlii root extract does not promote weight loss [6] making this another debunked ingredient, that would have been under dosed by vintage burn even if it did work.
