Dr. Stanley W. Jacob — The Father of DMSO

Jacob Laboratories is the family laboratory founded on the lifelong work of Stanley W. Jacob, M.D., F.A.C.S. Widely known as the “father of DMSO,” Dr. Jacob pioneered the medicinal study of dimethyl sulfoxide (DMSO) and its major metabolite, methylsulfonylmethane (MSM). Over a career spanning decades he worked with tens of thousands of patients and became recognized as a leading authority on the research and clinical applications of these compounds.

Dr. Jacob was the only physician featured exclusively on a national “60 Minutes” segment for his DMSO work. He authored and co-authored numerous books and papers, lectured around the world, and dedicated his life to exploring the therapeutic potential of DMSO and MSM.

Every product we make is formulated using Dr. Jacob’s decades of accumulated experience and a commitment to pharmaceutical-grade quality.
