BioMin F for Kids has been fully tested, and toxicology tests confirm that it is safe for use in children over 10kgs in weight. Due to regulations concerning instructions for use, most children's toothpastes are recommended for 3+ years as it is generally understood that young children cannot spit out excess product, and toothpaste should not be consumed. However, it is safe to use a smear of BioMin F for Kids toothpaste (rather than a pea-sized amount), as directed, for under 3s.
