At one time, algae was frequently used as a source of iodine, but this is now a dead industry, thanks to the introduction of cheaper processes. This ingredient is no longer widely used medicinally, partially because of the greater availability of iodine. However, some still believe that it may help to encourage weight loss by stimulating the thyroid gland. Unfortunately, there have been no clinical trials testing these claims.

Spirulina is one kind of blue-green algae that contains a wide array of vitamins and minerals. It is considered a complete protein, and contains roughly as much iron as a serving of beef, and can therefore be quite valuable to vegetarians.

This product is most likely to appeal to those who are looking for a multivitamin with a little something extra. At first glance, Green Source appears to be the ideal solution. However, simply because a manufacturer posts a lengthy list of ingredients, it does not necessarily mean that consumers will enjoy greater benefits. As a matter or fact, some herbalists argue that it can be difficult for manufacturers to fit enough of a given herb into their product for it to be effective. For this reason, consumers may be better off looking for a high-quality multivitamin that covers their basic nutritional needs, and supplementing it with an herbal formula that contains concentrated ingredients.

While we were pleased to see that the manufacturer posts a detailed list of ingredients for Green Source, regrettably, it does not post any scientific information. This is particularly disappointing considering that this product contains a number of ingredients that may not be familiar to consumers. We strongly recommend that supplement shoppers look for manufacturers that post results from clinical studies prominently on their websites, so that consumers can make an educated decision. For even greater reassurance, we also recommend looking for a manufacturer that offers free trial samples.
