KAL became one of the first nutritional companies to pioneer a concept originally known as “multiple supplementation.” KAL introduced one of the first multiple supplements to the American market by combining vitamins and minerals into a single tablet, called the Multi-Four. You can still buy its updated offspring, the Multi-Four+ today! Today, KAL offers a large assortment of single and combination vitamins and minerals to suit the needs of the busy lifestyles of the 21st century.
