<s>[INST] Hi Dr. Lundi, I am considering taking an advanced formula oral collagen supplement (types I II and III) as I have heard wonderful things about its benefits. However, I am still breastfeeding my 5 month old and I was wondering if this is safe or if I am better off waiting until she is through. Any insight into the matter would be greatly appreciated. Thanks for your time, Morgan Thank you Morgan [/INST] Thanks for asking on Chat Doctor. I do not think that you or your baby requires collagen supplements unless there are specific indications that you have. Collagen is a protein and would be broken down in the digestive tract in the same manner that chicken is digested. So it is not likely to prove helpful. At 5 months, your baby is about to complete the exclusive breastfeeding stage and weaning is to be done at 6 months of age when semi solids are to be introduced. I hope that helps. Feel free to revert in case of further queries if any. </s>
