BPI Sports Roxy Review

Roxy is BPI’s most recent fat-burner which contains some semi-interesting non-stimulant ingredients, but derives most of it’s weight-loss potential from Caffeine and Yohimbine…

CAFFEINE

Caffeine is by far the most common ingredient among stimulant-based fat-burners because it triggers the release of Noradrenaline, a potent activator of lipolysis.

Although Caffeine possesses pro-fat-loss properties, the effects tend to fade with prolonged use, rendering it ineffective as a long-term weight loss solution on its own. However, when paired with other fat-burning stimulants, Caffeine can kick-start the fat-burning process, so it’s a useful addition to the True GRIT Thermo formula.

BPI doesn’t tell us the exact dose of Caffeine in Roxy, but we estimate anywhere from 200-300mg per serving.

BOERHAAVIA DIFFUSA

A 2012 study from “BMC Complementary and Alternative Medicine” found that Boerhaavia extract demonstrated inhibition of α-glucosidase, an enzyme which breaks down starch. Inhibition of α-glucosidase could theoretically mimic a low-carb diet, a well-established mechanism with other weight-loss supplements such as Green Coffee Extract.

However, with absolutely no human research, it’s difficult to determine how influential Boerhaavia is in the context of Roxy.

LYCOPENE

Lycopene is Carotenoid (related to Vitamin A), high doses of which are present in Tomatoes. Lycopene is a versatile antioxidant which has been investigated for a variety of implications, but not so much for weight-loss. It may have certain mechanisms by which it helps promote a favorable body composition, but there is no evidence to indicate it can actually induce weight-loss.

BPI Sports does not mention anything specifically about why Lycopene was added to the Roxy formula, so for now we’d consider it more of a “support” ingredient than one that serves a specific purpose.

GINGER

Ginger is a very common household digestive aid, commonly prescribed by loving mothers for stomach problems.

However, a 2012 pilot study from “Metabolism” found that 2 grams of Ginger consumed with a meal increased caloric expenditure for several hours following the meal in overweight men.

Ginger has also been shown to increase Insulin secretion via acting as a serotonin receptor antagonist (serotonin normally suppresses insulin to some degree) in mice, though a human study using 1 gram of Ginger failed to replicate this results.

BPI doesn’t state how much Ginger or 6-Gingerol is present in Roxy, so it’s tough to say how much it really contributes to the overall effect of the formula.

YOHIMBINE

Yohimbine HCl is an alpha(2) receptor antagonist, meaning it inhibits the receptor responsible for blocking lipolysis (breakdown of fat). By blocking the action of this receptor Yohimbine allows for more lipolysis than would otherwise be possible from exercise.

A 2006 study, published in “Research in Sports Medicine”, found that Yohimbine supplementation (20mg/day) induced relatively significant fat loss in athletes (soccer players), but had no influence on measures of exercise performance.

BPI Sports does not list the exact amount of Yohimbine in Roxy but it generally only takes a few mg to produce noticeable effects. Users who are particularly sensitive to stimulants, however, may not react well to Yohimbine.

THE BOTTOM LINE

Roxy contains some moderately effective weight-loss ingredients, but BPI Sports is marketing it as some sort of break-through formula, which it isn’t. In combination with exercise, Roxy may help to burn some additional fat, and this effect may be primarily attributed to the stimulants (Caffeine and Yohimbine). At a little over 50 cents per serving, Roxy is priced more or less average (relative to other stimulant-powered fat-burners), but we feel there are better options within this same price range.
