I found a site worth looking into: Nutritional Health Supplements,

I am always very much interested in Nutritional Supplements because I do not believe that we get all the nutrients we need in todays farming in depleted mineral soil. Form Your Own Opinion.

This company carries only the highly reputed and effective brand-name natural, Ayurvedic and Homeopathic products. Each and every one of their product has been extensively researched and developed by its manufacturer and is constantly reviewed for improvements. Their products are then manufactured in accordance with Good Manufacturing Practice (GMP) to ensure the highest standard.

You ask what are Nutritional Supplements?

Traditionally, dietary supplements referred to products made of one or more of the essential nutrients, such as vitamins, minerals, and protein. But DSHEA broadens the definition to include, with some exceptions, any product intended for ingestion as a supplement to the diet. This includes vitamins; minerals; herbs, botanicals, and other plant-derived substances; and amino acids (the individual building blocks of protein) and concentrates, metabolites, constituents and extracts of these substances.

It’s easy to spot a supplement because DSHEA requires manufacturers to include the words “dietary supplement” on product labels. Also, starting in March 1999, a “Supplement Facts” panel has been required on the labels of most dietary supplements.
