Final answer:
The Dietary Supplement Health and Education Act of 1994 (DSHEA) changed the regulation of dietary supplements in the United States, shifting the responsibility for determining their safety to the manufacturers. While manufacturers have more freedom to distribute their products, they still need to meet FDA's Good Manufacturing Standards.
Step-by-step explanation:
The Dietary Supplement Health and Education Act of 1994 (DSHEA) changed the regulation of dietary supplements in the United States. Under DSHEA, the responsibility for determining the safety of dietary supplements shifted from the government to the manufacturers. This act also removed the requirement for approval from the U.S. Food and Drug Administration (FDA) before distributing a product.
However, manufacturers still need to meet the FDA's Good Manufacturing Standards, and while they are allowed to make certain claims about the benefits of their product, these claims are not approved by the FDA.
Overall, the DSHEA of 1994 gave more freedom to the dietary supplement industry but still required them to meet certain safety standards.
