In 1994, Congress passed the Dietary Supplement Health and Education Act (DHSEA). This law changed how the FDA oversees supplements. It made the rules less strict than for food and drugs. Because of this, the supplement industry has less regulation and some bad practices. Consumers need to be very careful about which brands they choose.

Many supplement makers use low-quality ingredients and don't test their products. This means what's on the label might not be in the bottle. Avoid the risk with third-party certifications like NSF. These certifications ensure the product is safe and accurate. Without them, you might risk your health and waste money.
