Oskar Thorvaldsson

Owner and CEO

Nutritional Supplement Manufacturers, Inc.

Oskar graduated with his MBA from MIU in Fairfield, Iowa and has always been interested in furthering the use of natural products.

Oskar started “Nutritional Supplement Manufacturers, Inc.” in 2011. The factory was however established under another name in 1993, PureNSM has always focused on pure production methods and intense testing of raw materials and finished goods. 

PureNSM only accepts clients that value selling products that meet label claims. Oskar states that “it’s very important to NOT rely on a PDF of a GMP certification from NSF and Underwriters Laboratories (UL). The only way to verify a manufacturer is to look them up on the NSF and UL websites”.
