There is no such thing as “what are the best vitamins for women”. Women need a balanced intake of vitamins to maintain a healthy body. Vitamins include Vitamin A, B vitamins, Vitamin C, Vitamin D, Vitamin E, Vitamin K, etc. You can’t have one without the other, but you can’t have too much of them, as too much of them can lead to side effects. Taking vitamin A as an example, the functions of vitamin A include: promoting the production of optic cone cells to maintain night vision; maintaining the integrity of epithelial cells; promoting bone development; and maintaining human fertility. However, an overdose of vitamin A can lead to loss of appetite, irritability, drowsiness, vomiting, optic papillary edema, etc. For children, there will also be fontanel bulging, head circumference increase and other adverse reactions. So the intake of all kinds of vitamin tablets must be under the guidance of the doctor, not unauthorized medication.
