Vitamin World Xtreme Trim Metabocore Review

Editor's Review: 3.5 / 5.0

​What You Should Know

The weight loss market brings in billions of dollars every year. All it takes is the proper facilities to formulate and sell a weight loss supplement, but that does not mean every supplement is safe and effective. Vitamin World Xtreme Trim Metabocore claims to boost metabolism and increase thermogenesis or fat burn. The ingredient list contains several known weight loss ingredients. These ingredients are not always the most effective. Manufacturers need to include proven ingredients with clinical support for the dieter to trust the product will work to help them achieve weight loss. Vitamin World Xtreme Trim Metabocore does not include all the best ingredients.

List of Ingredients

Vitamin C, Thiamin, Riboflavin, Niacin, Vitamin B6, Vitamin B12, Biotin, Pantothenic Acid, Calcium, Magnesium, Chromium.

Proprietary Blend: Caffeine, Magnolia, Passion Flower, Scullcap, Panax Ginseng Extract, Pinellia, Poria, Jujube, Phosphatidylserine, DHEA.

Product Features

Chromium is the first ingredient in Vitamin World Xtreme Trim Metabocore proven to have positive effects on weight loss. The exact effect has to do with blood glucose control. Chromium prevents blood glucose from dropping after digestion of simple carbohydrates and other foods. This prevents the brain from signaling hunger. Hunger between meals is often attributed to a drop in glucose levels. Caffeine is the first ingredient in the proprietary blend. We have no idea how much caffeine is included in the supplement. Dieters sensitive to caffeine need should never take the full dose of a supplement that contains unknown amounts of caffeine. Caffeine can cause increased heart rate and blood pressure.

Magnolia is commonly used to fight diarrhea and stomach issues. Passionflower affects mental state by reducing anxiety. This ingredient is similar to valerian root and should only be taken under the care of a physician. Scullcap is another ingredient similar to valerian root. When combined with valerian root it can have sedative properties. Panax ginseng is a memory herb. It helps improve memory and focus. Pinellia is a stimulant closely linked to Ephedra. In some cases, labels on supplements containing pinellia have listed ephedra as an active ingredient. Poria is a diuretic. This ingredient will increase urination and force water out of the body.

Vitamin World Xtreme Trim Metabocore is not the safest or most effective weight loss supplement. The ingredient list includes a diuretic and stimulant similar to ephedra. The two proven ingredient benefits are outweighed by potential negative side effects.
