SUPERthrive is a liquid concentrated growth enhancer product for plants, which has been available since 1940. It contains ".09% vitamin B1, .048% 1-Naphthyl acetic acid", plus over 50 secret proprietary ingredients that the company does not disclose.

The packaging says that it should be included in the normal fertilizing program to improve some 50 phases of horticulture.

The hormone 1-Naphthyl acetic acid (NAA) does not occur naturally. Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), products containing NAA require registration with the Environmental Protection Agency (EPA) as pesticides. The sale of Superthrive is prohibited in Wisconsin and South Dakota as an unregistered pesticide.

In 1972, six votes in the U.S. Congress protected SUPERthrive from competition. The legislation was supported by 36 professional, trade and horticultural associations, and over 3,000 professional petitions.

Suggested uses include transplanting, reviving, and general strengthening of growth of trees and other plants.

The SUPERthrive product claims to have many adherents, not only professional horticulturists, but, according to its packaging: "US Departments of Agriculture, Army, Navy; states, cities, counties, universities."

SUPERthrive was developed by Dr. John A. A. Thomson. He was the first chemist to receive the National Lawn & Garden Marketing & Distribution Association's Lifetime Achievement Award in 2006.
