Natrol is an American nutritional supplement company founded in 1980 by Elliott Balbert. With more than four decades of experience in the vitamin and supplement industry, the company has developed into a highly recognized brand in the United States, with a particularly strong specialization in melatonin and sleep-support supplements.

Natrol's philosophy focuses on developing straightforward, carefully formulated supplements, with particular attention to ingredient quality and manufacturing control. Today, the brand has a strong focus on sleep and general wellness products, using ingredients such as melatonin, magnesium, and botanicals in a variety of formats including tablets, gummies, liquids, and drink mixes.

Particular emphasis is placed on quality control. According to Natrol, every lot of finished products is tested for safety, quality, strength, composition, and consistency, while formulations are designed to maintain their intended potency throughout the product's shelf life.

The manufacturing facilities used by the company have also earned third-party certifications such as NPA GMP (Good Manufacturing Practices), reflecting compliance with established quality and manufacturing standards for dietary supplements.

Although Natrol is best known for its extensive melatonin range, its portfolio also includes products containing magnesium, 5-HTP, cognitive wellness supplements, and specialized wellness formulas, along with options designed for different age groups and nutritional needs.

With decades of experience, strong specialization in the sleep category, and an established focus on quality control, Natrol has developed a recognizable position within the international nutritional supplement market.
