This multivitamin and mineral capsule contains several vitamins and trace elements such as B vitamins, folic acid, zinc, selenium, and others. During breastfeeding, such supplements may be used when there is a nutritional need, but safety and suitability depend on your diet, health status, and total daily nutrient intake from other sources. Because this product has a wide combination of ingredients, it should only be taken after advice from a doctor, who can confirm whether it is appropriate and necessary for you during breastfeeding.
