G FUEL is made from natural vitamins, minerals, and fruits that grow in the soil. Like all natural vitamins and minerals, they absorb trace amounts of lead from the soil. California, a state in the USA, requires companies to issue a warning if products, based on the manufacturer's knowledge or assumptions, could cause exposure of at least 0.5 micrograms (µg) of lead per day. G FUEL wants to ensure they comply with California's requirements. This limit in California is much stricter than the daily limit set by the US Food and Drug Administration (FDA) of 75 µg for adults and 6 µg for children. It's important to emphasize that this Californian regulation also goes far beyond what is considered safe in many other parts of the world, including Europe.
