Copper (as Fermented Copper Bisglycinate)
Also known as: copper bisglycinate, fermented copper, chelated copper
Copper is an essential trace mineral required for iron metabolism, collagen synthesis, and fetal development. The bisglycinate chelate form enhances absorption and reduces potential for GI irritation.
