Peak Performance supplements are made in the United States and developed for busy athletes and professionals.

In addition to being free of major allergens, including soy, dairy, wheat, egg, shellfish, and peanuts, Peak Performance Raw Liquid Zinc is also vegan-friendly.

All Peak Performance supplements undergo third-party testing for quality and accuracy. They’re also manufactured following CGMP regulations and standards.

Adults should take 1 full dropper (1 mL) once a day on an empty stomach or use as directed by a doctor.
