Fucus Vesiculosus – A Key Ingredient In Weight Loss Patches

Published:July 28th, 2010

Fucus vesiculosus is one of the ingredients present in weight loss patches and it has been claimed that it can help with losing weight. Fucus Vesiculosus is also known as Bladderwrack, black tang, rockweed or sea oak and is a seaweed found on the coasts of the Atlantic and Pacific Oceans, The Baltic and North Sea.

It is rich in iodine and was used to treat iodine deficiency. As a thyroid stimulant it is included in weight loss patches due to its capacity to increase metabolic rate. Besides iodine, Fucus vesiculosus is also rich in beta-carotene, bromine and potassium.

Another chemical constituent is alginic acid that can form a seal at the top of the stomach upon contact with water and due to this effect has been used in treatments for heartburn. Heartburn is associated with regurgitation of gastric acid.

The same property of the alginic acid makes Fucus vesiculosus a laxative. There have been claims of the positive effects of these algae on the immune system, but there is not enough evidence to support such claims yet.

In Asian populations, where there is higher seaweed consumption, lower levels of plasma cholesterol were measured. Pilot data also suggested that dietary Fucus vesiculosus is responsible for the reduced risk of estrogen related cancers in Japanese populations. Seaweed accounts for 10 to 25% of the food intake in Japanese diets. Fucus vesiculosus has been shown to possess antibacterial and antioxidant properties due to the high polyphenolic content.

Fucus vesiculosus consumption has been proven to alter the cholesterol mechanism and significantly lower plasma cholesterol levels. Studies have been performed only on laboratory animals, and those on humans are yet to be conducted to determine the effects of Fucus vesiculosus consumption. The only studied conducted so far involved only a small number of subjects and with no control groups. Control groups are administered placebo in order to assess the complete effect of Fucus vesiculosus consumption.
