Doctor Reviews: Bovine Colostrum

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.

Atrafen Elite is a caffeine supplement that contains poorly studied compounds that are neither effective nor safe for weight or fat loss.

Cayenne does not burn fat in humans. In reality, Fire Bullets doesn’t seem to offer much more benefit than a standard caffeine supplement.

Hyleys Slim Tea is a basic combination of green and senna tea. A regular organic green tea would likely be better for slimming.

Lemme Burn claims that AMPK activation will help fat loss. But research says this is not true if you don’t suffer from diabetes or PCOS.

OLLY Combat Cravings is nothing more than a very high dose chromium supplement, which is not safe or effective for cravings.

Capsiplex Burn uses Capsimax, a proprietary cayenne extract. Unfortunately, studies show that cayenne isn’t effective for fat burning.

PhenQ PM is not useful for fat burning at all. Trying to burn more fat at night with supplements is not physiologically possible.
