Analysis, Certificates & Benefits

Benefits of Vitamin K2

Certificates / Sources

Below is a list of documents which support our standards. The first three documents are certifications from the manufacturing company. These are proofs of GMP status. According to Wikipedia ‘GMPs are enforced in the United States by the US FDA, under Section 501(B) of the 1938 Food, Drug, and Cosmetic Act (21 USCS § 351). The regulations use the phrase “current good manufacturing practices” (cGMP) to describe these guidelines.’

The Certificate of Analysis is proof that the final testing of the product passed requirements for potency. The actual concentration of K2 was 54mcg as opposed to our claimed 50mcg. There have been documented situations where the claimed end product did not contain what the label claimed.

  • GMP Requirements in NSF-ANSI Standard 173
  • GMP for Sport (Radecki)
  • NPA Certificate (August 2012 – July 2013)
  • Certificate of Analysis Vitamin K2
