Nursing mothers can usually take vitamin C, but it should be noted that it should be supplemented as needed to avoid overdose, and should be discontinued if adverse reactions occur after taking it. Vitamin C is the name of a western drug that can be used to treat scurvy and as an adjunctive treatment for a variety of acute and chronic diseases. Vitamin C also maintains immune function and participates in tissue repair. Breastfeeding women who have a deficiency of vitamin C in their body can take some vitamin C appropriately. However, it should be noted that vitamin C should not be taken in excess, otherwise adverse reactions may occur, such as diarrhea, headache, frequent urination, nausea, vomiting and stomach cramps. Taking large amounts of vitamin C for a long time also tends to cause urate and oxalate stones. If you take vitamin C for a long time, it is easy to cause scurvy after suddenly stopping the drug, which is not good for your health. Allergic to vitamin C is prohibited. Nursing mothers can generally take vitamin C, but it is best to take it under the guidance of a doctor to avoid abuse of the drug. Pay attention to diet and rest during breastfeeding.
