Doctor Reviews: ZBiotics

ZBiotics uses the probiotic Bacillus subtilis ZB183, however there is no evidence it can metabolize alcohol or help in hangovers in humans

Bee bread is fermented bee pollen, and may be quite nutritious, but lacks any researched health benefits in humans.

When comparing the cognitive-enhancing effects of PreVagen and Neuriva, it’s clear that Neuriva is the more effective option.

Ark Drops and Hustle Drops are no more useful than dropping pure peppermint oil into your mouth and expecting a performance boost.

Sugar Defender uses doses that are so low, you might as well be dropping water into your mouth. It’ll have about the same effect.

Mushroom coffee tries to enhance its health benefits by adding powdered mushrooms, but the evidence behind these benefits are weak at best.

NZT-48 Premium Brain Booster contains an excessive number of ingredients, resulting in inadequate doses for nearly every component.

Bovine colostrum supplements offer modest support for gut healthand immunity. However, their efficacy may be overshadowed by probiotics.

Fitspresso uses doses that are too low to be effective, even though some of its ingredients may have been useful for blood sugar control.

Like many other “night-time fat burners”, NiteLEAN is just a regular sleep aid that does nothing for actual fat burning.

Puravive is a shameless rebrand of Expiure, a completely useless supplement built entirely on false science and empty promises.

Hourglass Fit isn’t much more than a fancy glucomannan soluble fiber supplement. These supplements don’t work without a proper diet plan.
