As the oldest supplement manufacturer to serve the special needs community, Kirkman Labs have established themselves as the industry leader with regard to quality and efficacy. Since they're a basic manufacturer, they're able to test for over 950 different toxins, contaminants, and excipients. Most nutraceutical companies do not manufacture their own formulations, which means they cannot guarantee quality, safety, and potency with 100% assurance.
With regard to quality testing, Kirkman products far exceed the FDA-mandated requirements for testing for contaminants due to their continual investment in the most effective products and cutting-edge technology in the industry. Every single raw ingredient is tested for hundereds of pesticides and chemicals, as well as bacteria, yeast and mold counts, dangerous heavy metals, and known allergens. By purchasing Kirkman Labs, you can rest assured that you and your loved ones are receiving the finest, all natural vitamins and supplements available today.
