The history of Weider Nutrition International begins with that of founder Joe Weider. He was born in 1923 in Montreal, Canada, and dropped out of school at age 12 to support his family. He was a skinny adolescent and hated being pushed around by stronger kids. So one day Weider decided to start a work-out program, building his own weight set from junk yard parts.
One of the companies founded by Joe Weider to promote health and physical fitness, Weider Nutrition International, Inc., is a leader in the nutritional supplement and natural products industry. The company manufactures both its own branded items, such as Mega Mass powdered drink mix, Fat Burner supplements, and Tiger's Milk energy bars, and also private-label botanical capsules and tablets and sports beverages. Such products had for years been sold mainly to bodybuilders and weight lifters, but in the 1990s Weider began making supplements for endurance athletes and the general public.
Weider said that it would expand the Las Vegas plant to meet consumer demands and that Science Foods would continue to operate under its own name.
