Vitamin B6 can usually be taken by two-month-old infants, but it needs to be taken under a doctor’s supervision to avoid overdose. Vitamin B6 is an important component of coenzymes, involved in the normal metabolism of sugar, protein, fat. And it is related to the production of white blood cells and hemoglobin. At the same time, vitamin B6 can also promote the production of gastric acid in the digestive system to help babies digest food. Therefore, when your baby has indigestion, vomiting and other symptoms of vitamin B6 deficiency, you can take vitamin B6. It should be noted that vitamin B6, which is a drug, must be used correctly under the guidance of a doctor, and should not be dosed arbitrarily to avoid peripheral neuritis and other conditions caused by too much vitamin B6 supplementation.
