Whether or not it’s from a boutique well being model, a jar filled with fruity gummies, or a standard white bottle from a neighborhood pharmacy—most People take a vitamin daily. In truth, 86% commonly take nutritional vitamins, in keeping with a web based survey carried out by The Harris Ballot on behalf of the American Osteopathic Affiliation. Ninety-seven p.c of girls take prenatal nutritional vitamins or multivitamins throughout being pregnant, in keeping with the same survey carried out by The Harris Ballot for March of Dimes. However who really wants these nutritional vitamins, and the way a lot do they enhance your well being?
For many years, nutritional vitamins have been marketed as a simple technique to make up for a poor food regimen and get the important vitamins your physique wants. However the newest science says that multivitamins—whether or not they’re a particular formulation for girls or not—aren’t nearly as good in your general well being as you may think. A scientific evaluate examined 5 randomized, managed trials with 47,289 folks and located that nutritional vitamins had no impact in girls on major prevention of persistent ailments or improvement of most cancers. So do you have to be taking a each day multivitamin for girls? The specialists say “probably not.” Right here’s why.
Frequent elements in a multivitamin for girls
If you decide up a bottle of nutritional vitamins that claims “specifically formulated for women,” what does that imply? Is it for bone well being or pregnant girls?
“Many brands of vitamins marketed toward women will have high levels of certain nutrients that women are commonly deficient in, such as iron or calcium,” says Whitney Linsenmeyer, Ph.D., RD, LD, spokesperson for the Academy of Vitamin and Dietetics and assistant professor of vitamin at Saint Louis College.
However being labeled as “women’s specific” might imply nothing in any respect. “There is plenty of marketing to suggest that multivitamins for women are distinct from other multivitamins. The reality is that there is no legal or regulatory definition for multivitamins, including those marketed specifically to women.” In different phrases, girls’s nutritional vitamins could also be no totally different from different dietary supplements.
Mostly, girls’s nutritional vitamins will comprise a protracted listing of important nutritional vitamins and minerals, together with: vitamin A, B nutritional vitamins (vitamin B6 and vitamin B12), vitamin C, vitamin E, calcium, iron, magnesium, potassium, thiamin, riboflavin, niacin, folate, and biotin. Nonetheless, nutritional vitamins and dietary supplements aren’t regulated by the Meals and Drug Administration (FDA). Meaning they aren’t topic to their requirements or legal guidelines, so ingredient lists and quantities can broadly range. And the efficacy of the elements will not be promising.
Do nutritional vitamins for girls actually work?
Any scientist or researcher could be hard-pressed to recommend a each day multivitamin—for the next causes.
There’s not sturdy proof of advantages.
At the same time as early as 2006, the Nationwide Institute of Well being mentioned there wasn’t sufficient proof to advocate taking multivitamins. Moreover, an editorial that accompanied a 2013 research revealed within the Annals of Inside Drugs was fairly easy with the title: “Enough Is Enough: Stop Wasting Money on Vitamin and Mineral Supplements.”
Many specialists are taking a definitive stance on dietary supplements, stating that most individuals ought to cease spending their cash on multivitamins after seeing research after research show their profit to be small, or nonexistent—particularly for postmenopausal girls. A Girls’s Well being Initiative research discovered that postmenopausal girls who took multivitamins didn’t have a decrease demise price than others and have been simply as prone to develop heart problems or cancers of the lung, colon, rectum, breast, and endometrium—these outcomes which can be in keeping with findings from different a plethora of different research.
Nutritional vitamins could possibly be dangerous.
Surprisingly sufficient, some analysis is discovering that not solely are multivitamins a waste of cash, they’re additionally a hazard to your well being. “The quantity of vitamins and minerals in any supplement is important, especially when considering the risk of exceeding the upper limit intake of a given nutrient—as this may pose a risk for toxicity, which can have significant adverse health effects,” Linsenmeyer says. “Consumers are encouraged to not exceed the recommended dosage, and to work with their physician and/or registered dietitian to ensure they are not at risk for toxicity or any adverse interactions with other foods or medications.”
“Certain vitamins and minerals can impact that absorption of medications, either inhibiting the absorption or increasing it,” says Willow Jarosh, MS, RD, and proprietor of Willow Jarosh Vitamin in New York Metropolis. “In addition, some supplemental nutrients can have similar effects to medications—so if you’re taking a medication that, say, thins the blood and also taking a multivitamin that has a mild blood thinning effect, that could compound the effects.”
It’s greatest to get vitamins from meals.
That’s why most well being specialists, nutritionists, and dietitians advocate getting your nutritional vitamins and minerals from the meals you eat. “I follow a food-first philosophy, meaning it is ideal to get the nutrients you need through whole foods,” Linsenmeyer says. “This is because the nutrients in whole foods are often better absorbed than in supplement form, whole foods contain other beneficial compounds beyond just vitamins and minerals—such as phytochemicals and fiber, and there is low risk for consuming micronutrients in excess from whole foods.”

Nonetheless, there are exceptions to the foundations—as is the case with girls who’re pregnant or lactating, and populations which can be in danger for a vitamin or mineral deficiency. In these particular circumstances, dietary dietary supplements are routinely really useful.
What dietary supplements ought to girls take?
The Workplace on Girls’s Well being, a department of the U.S. Division of Well being and Human Providers, recommends these nutritional vitamins for girls:
Although the quantity wanted varies by age, well being, and food regimen.
Folic acid/folate (vitamin B9)
“Folic acid is a good idea for people who are planning on becoming pregnant,” Jarosh explains. “Having sufficient intake of this nutrient can help prevent neural tube defects in babies.” The Facilities for Illness Management and Prevention recommends that girls of reproductive age get 400 micrograms (mcg) of folic acid each day to forestall start defects. Although the really useful quantity rises to 4,000 mcg for those who change into pregnant or have a household historical past of spina bifida, in keeping with the Workplace on Girls’s Well being.
There are some exceptions, one being “people who have a genetic variation—called MTFHR—might have trouble converting folic acid into a form of folate that their body can use,” explains Jarosh. These sufferers ought to focus on with their doctor the kind and quantity of folic acid that’s greatest for his or her state of affairs. Folic acid can even work together with essential medicines for epilepsy, diabetes, lupus, and rheumatoid arthritis.
“I think folic acid is a great example of the idea of taking the nutrients that you need as an individual, but that supplementation isn’t necessarily something that is one-size-fits-all or something that we all need to do,” says Jarosh. “Genetics, lifestyle, food choices, and health status all factor into whether a person needs supplements and which ones they need.”
Vitamin B-12
Vitamin B12 is a nutrient that helps preserve the physique’s nerve and blood cells wholesome. The Nationwide Institutes of Well being recommends that grownup girls get 2.4 mcg of B12 each day. That quantity rises to 2.6 mcg throughout being pregnant, and a couple of.8 mcg whereas breastfeeding.
Those that are poor in it are sometimes extremely fatigued and weak—and there are many the reason why somebody could possibly be poor. “Older people might not be able to absorb as much B12 from food, while vegans or vegetarians may have trouble getting enough because B12 is found naturally in animal products,” Jarosh explains.
Sure well being situations can even influence vitamin absorption. “People who have digestive diseases like Celiac disease or Crohn’s disease may have trouble absorbing enough B12 from food. Same goes for people who have had GI surgeries including weight loss surgery. There’s also a condition called pernicious anemia in which a person doesn’t make intrinsic factor—so they can’t absorb B12. All of these conditions and circumstances would warrant a person having some sort of B12 supplement.”
Vitamin D
The Nationwide Institutes of Well being recommends that adults get 15 mcg (600 IU) of vitamin D each day. After age 70, that quantity will increase to twenty mcg (800 IU), which might be tough for those who put on sunscreen (it’s best to!), spend most of your time indoors, or have a vitamin D deficiency. In these circumstances, a complement might be useful.
Calcium
Some docs might recommend girls taking calcium dietary supplements, which might be important in preserving sturdy bones—particularly in postmenopausal girls. The really useful quantity varies by age from 1,000 mg to 1,300 mg, in keeping with the Workplace of Girls’s Well being. Research recommend that the majority girls don’t get the really useful each day worth of calcium each day from their food regimen, which might result in osteoporosis or different well being issues.
Iron
Iron is really useful when your purple blood cell depend is low or prone to changing into low—for instance, if you’re anemic. However there are different circumstances during which supplemental iron is required for girls. Based on the workplace of Girls’s Well being, the quantity you want all through your life is:
“In addition to women with or who are prone to anemia, iron will often be prescribed to women who are pregnant,” Jarosh says. “During pregnancy, blood volume increases and along with this iron needs increase—so supplemental iron is often recommended.” Simply be sure you discuss to your healthcare supplier earlier than taking a complement. It’s necessary to search out out what’s inflicting low purple blood cell counts earlier than treating, in keeping with Jarosh.
Speak to your healthcare supplier
The nutritional vitamins—and dosages—you want based mostly in your age and well being situations, reminiscent of being pregnant. “Some [daily reference intake] recommendations do not vary dramatically; for example, vitamin D needs for women remain fairly constant from childhood through adulthood, regardless of pregnancy or lactation,” says Linsenmeyer. “Others change quite a bit throughout the lifespan, such as iron needs that more than double during a woman’s childbearing years and more than triple during pregnancy.”
In different phrases, there’s no one-size-fits-all resolution for getting the vitamins you want for optimum well being. In case you are involved a few vitamin deficiency, seek the advice of your doctor about what applicable supplementation might appear like. It’s totally different for everybody, so it’s seemingly one pill can’t clear up all of our wants.
