Also consider these facts:
• Vitamins are synthetically manufactured all over the world in hundreds of different factories from potentially contaminated soil.
• Herbs and spices are grown all over the world in potentially contaminated soil and then sprayed with pesticides to control insects, fungi and parasites.
• Dehydrated fruits and vegetables used in supplements can also be grown in contaminated soil and sprayed with pesticides.
• Many dietary ingredients contain common allergens, which should be avoided by many individuals.
There aren't a lot of specific government regulations regarding purity testing for nutraceuticals. Unless a manufacturer actually tests for contaminants - they cannot guarantee a product's purity. This is why Kirkman's Ultra Tested® product line is so revolutionary. Kirkman® tests every product it manufactures for more than 950 environmental contaminants including heavy metals, bacteria, yeast, mold, pesticides, fungacides, insecticides, biocides, endocrine disruptors and other harmful chemicals.
Supplement Companies Generally Only Test for What is Required by the FDA
Testing for potentially harmful cotaminants is difficult and expensive. Detection for many of the most harmful toxins requires state-of-the-art equipment, methodologies and procedures. Without these, manufacturers can know for sure what contaminants their products contain.
