Member's Mark Super B-Complex

Member's Mark Super B-Complex is a dietary supplement designed to support energy metabolism and nervous system health. It is a private label brand exclusively distributed by Sam's Club, which is a division of the retail giant Walmart.

Member's Mark was established in 1991 by Sam's Club to provide high-quality items at competitive prices, competing with national brands across food, household, and health categories. While the products are branded by Sam's Club, they are manufactured by a network of white-label suppliers primarily located in the United States and other global locations under strict quality control standards. Ownership remains under Walmart Inc., the world's largest retailer by revenue, headquartered in Bentonville, Arkansas.
