Does Nature’s Way Laminaria Extract work?
What is it?
Nature’s Way Laminaria Extract is an all-natural diet pill, the active ingredient of which is Laminaria powder.
The manufacturer’s website makes some pretty amazing claims for this product which, if proved, could cure the western world’s obesity problem single-handedly.
It suggests the diet pill will burn off up to a pound of fat a day without the need to diet; and that “Laminaria works because it unlocks and then destroys fat from the inside-out”; that cellulite will disappear and that users will look younger and feel healthier and happier.
Sounds a load of rubbish, so lets take a deeper look to see if its as good as the manufacturer claims.
Is its main ingredient, Laminaria, effective?
Laminaria is a genus of brown algae (seaweed) that is native to Japan. Commonly known as kelp, and contains iodine, iron and potassium.
It is thought to have the potential to aid weight loss because, on contact with water, laminaria forms a gel, which makes the body feel full and has a natural laxative effect.
Iodine is known to affect thyroid activity, and the manufacturer claims that regulation of the thyroid gland through the Iodine in this product will increase the level at which the body burns fat.
Although scientific research has proved that Iodine affects thyroid function, the manufacturer’s website gives no indication as to the quantity of Laminaria in this product, hence it is impossible to determine the extent to which this supplement will be effective.
There have so far been no human clinical trials testing the weight-loss properties of Laminaria.
A recent study on rats produced promising results, concluding that Laminaria Extract reduced glucose and insulin levels and increased fatty acid oxidation in obese rats.
It is possible, but by no means certain, that these results would be replicated in human clinical trials, but clearly further research is needed before it can be regarded as an effective – and safe – weight-loss tool.
Nature’s Way Laminaria Extract seems to work by over-stimulating the thyroid gland, which in turn increases the metabolic rate. I would like to see some credible scientific research into the effects of thyroid stimulation on humans before I would be happy to try this product.
Despite promising research on rats, Laminaria has not been tested on humans for either its weight-loss properties or its safety. On the other hand, there are many alternative products available which have been proven both effective and safe fat-burners and appetite suppressants.
Until such time as scientific research on human subjects gives this product a clean bill of health and proves its effectiveness, the claims of the manufacturer remain unproven, and Nature’s Way Laminaria Extract is a diet pill that is hard to give any real recommendation.
