Women need many of the same essential vitamins and minerals as men, but nutritional needs can change with age, pregnancy, breastfeeding and other stages of life. There is no single multivitamin that is best for every woman.
The best approach is to get most nutrients from a varied diet and use supplements when there is a specific nutritional need.
1. Vitamin D
Vitamin D helps the body absorb calcium and plays an important role in maintaining healthy bones and muscles.
Sun exposure, fortified foods and foods such as fatty fish can provide vitamin D. Some people may need a supplement if they don’t get enough from these sources.
2. Calcium
Calcium is particularly important for maintaining strong bones and teeth. Women become more vulnerable to bone loss as they get older, making adequate calcium intake especially important.
Good food sources include dairy products, fortified plant-based beverages, tofu made with calcium, and some leafy green vegetables.
3. Iron
Iron is needed to make hemoglobin, which helps carry oxygen throughout the body.
Women who menstruate can lose iron through menstrual bleeding, so their requirements may be higher than those of many men.
Iron is found in foods such as lean meat, beans, lentils, spinach and fortified grains. Taking an iron supplement without a demonstrated need isn’t recommended because excessive iron can be harmful.
4. Folate
Folate, also known as vitamin B9, is essential for cell growth and normal DNA production.
It’s particularly important before and during pregnancy because adequate folate helps reduce the risk of certain birth defects.
Good sources include leafy green vegetables, beans, citrus fruits and fortified grain products. Women who could become pregnant should discuss appropriate folic acid supplementation with their healthcare professional.
5. Vitamin B12
Vitamin B12 supports red blood cell production and normal nervous-system function.
It’s naturally found mainly in animal-derived foods, while some plant-based foods are fortified with B12. People following a vegan diet may need a B12 supplement or fortified foods.
Older adults and people with certain medical conditions may also have difficulty absorbing B12.
6. Vitamin C
Vitamin C supports normal immune function, collagen production and iron absorption.
Citrus fruits, strawberries, bell peppers, tomatoes and broccoli are good sources.
Most people can obtain enough vitamin C through a varied diet.
7. Vitamin B6
Vitamin B6 is involved in numerous processes, including protein metabolism and normal nervous-system function.
It can be obtained from foods such as poultry, fish, potatoes, chickpeas and bananas.
High-dose B6 supplements should not be taken routinely unless recommended by a healthcare professional, as excessive amounts can cause nerve problems.
Do Women Need a Multivitamin?
Not necessarily.
A multivitamin can be useful in some situations, but it shouldn’t be considered a replacement for a nutritious diet. The right supplement depends on factors such as age, diet, pregnancy status, medications and individual nutritional needs.
Taking more vitamins isn’t automatically better, and some nutrients can cause harm when consumed in excessive amounts.
Vitamins During Pregnancy
Pregnancy changes nutritional requirements considerably. Nutrients such as folic acid, iron, iodine and other vitamins and minerals become especially important.
If you’re pregnant, trying to become pregnant or breastfeeding, speak with your healthcare professional about which prenatal or other supplements are appropriate for you.
The Bottom Line
There isn’t one “best” vitamin for every woman. Vitamin D, calcium, iron, folate, vitamin B12, vitamin C and vitamin B6 all have important roles, but individual requirements vary.
The best starting point is a balanced diet that includes vegetables, fruits, whole grains, legumes, nuts, seeds, dairy or fortified alternatives and appropriate sources of protein. Supplements should be used when they address a genuine nutritional need.
