The nutritional products we sell and endorse are sourced from either professional line companies unavailable at health food stores, or from highly reputable manufacturers. The products available are selected based on experience, independent laboratory analysis, and efficacy. Recent government audits of commercial nutritional products find that less than 20% meet label claims!  In addition, many are irradiated, adulterated, substituted, or ineffective.  Our products are chosen to provide high efficacy, excellent quality, and purity.
