Diet Metabo-7 by Source Naturals claims to increase metabolism, helping the dieter achieve weight loss goals. Most fat burners contain stimulants to increase heartbeat and calorie burn. According to the product description for Diet Metabo-7, overstimulation is not a problem with this fat burner. The ingredient list will prove or disprove this claim.

Source Naturals lists retailers where products are available for purchase. The company also lists a suggested retail price so dieters can compare retailer prices to suggested prices to ensure they receive the best deal.

List of Ingredients

Vitamin C, Niacinamide, Vitamin B6, Pantothenic Acid, Iodine, Chromium, Sodium, Potassium, Guarana Seed Extract, Phenylalanine, GABA, Gymnema Leaf Extract, Yerba Mate Leaf Extract, Glutamine, Acetyl L-Carnitine, L-Tyrosine, Horse Chestnut Extract, Dandelion Root Extract, Kola Nut Extract, Bladderwrack Leaf Extract, Gingko Leaf Extract, Ginger Root, N-Acetyl Cysteine, Aloe Vera Leaf Concentrate, Gentian Root Extract, Bupleurum Extract, Green Tea Leaf Extract, Dandelion Root Extract, Guggul Extract, Black Pepper Fruit Extract.

Product Features

For a supplement that claims it will not cause overstimulation there are quite a few stimulants on the ingredient list. Guarana seed extract, yerba mate leaf extract, kola nut extract and green tea leaf all contain caffeine or some form of caffeine-like stimulant. The only proven ingredient associated with weight loss on that list is green tea leaf, but there is only 12 mg included in the formula. That is about 320 mg too few for optimal green tea benefits.

Another negative side of Source Naturals Metabo-7 is the fact that diuretics and laxatives make up a large portion of the supplement. Horse chestnut extract, dandelion root extract and bladder wrack are diuretics that cause water loss. Aloe vera concentrate is a natural laxative. Laxatives and diuretics are not proven weight loss ingredients. They are proven to cause negative side effects when taken for an extended period like dehydration and reduced bowel function.

The other ingredients in the formula may have positive benefits like L-Tyrosine to reduce blood pressure and ginger root to ease stomach discomfort but these ingredients do not outweigh the negative effects of stimulants, diuretics and laxatives.

Source Naturals Diet Metabo-7 sells for $14.98 per 45 tablets from third-party retailers.
