Overview

Klean Athlete Klean Multivitamin is a comprehensive multivitamin specifically formulated for competitive athletes and carrying the NSF Certified for Sport designation. This means every batch is tested for over 200 banned substances, making it safe for Olympic, professional, and collegiate athletes subject to drug testing. The formula provides essential vitamins and minerals with emphasis on nutrients that athletes deplete through intense training: B vitamins for energy metabolism, antioxidants for recovery, and minerals for electrolyte balance. Klean Athlete is a sub-brand of Douglas Laboratories, a practitioner-grade supplement company.
