Nutritional supplements, most especially the manufacturers we list herein, are extremely popular. In fact, they are so popular, that a black market for their products, or "like" products exists. Many of these non-certified distributors offer their products via online stores and are some of the best-paying advertisers on search engines, such as: Google and Yahoo. What's important to note however, is that the authenticity and safety of products obtained from these non-certified sites are NOT guaranteed by the manufacturers whose name appears on the label.

Oakway Health Center, Inc. provides the following toll free phone numbers for the manufacturers listed on our site for any inquiries you may have in regards to a distributor's certification.
