The Best Supplements for Women

By Karla Walsh Yes, it’s possible to get all the nutrition you need from food, but lots of women still fall short (hey, we’re busy!). “Many of the most commonly-slighted vitamins and minerals are key to keeping the body functioning properly,” says Suzanne Dixon, MPH, MS, RD, an epidemiologist with Cambia Health Solutions. “The best way to determine which supplements you might need is to keep a diet record—it doesn’t have to be precise on serving sizes, just a general overview of what you eat on a day-to-day basis—and review it with a dietitian.” From there, they can suggest supplements if needed. How to Choose the Best Supplements for Women High-quality dietary supplements will note that they:  Were made in a facility that follows “GMP,” or good manufacturing practices, which are guidelines set by the Food and Drug Administration (FDA), or… Meet US Pharmacopeia (USP) standards It’s even better if the product has been tested by an independent, third-party laboratory, such as consumerlab.com, Dixon says, in order to verify that the product is well-made, breaks down in a way the body can actually absorb, contains what is indicated on the label, and is free of potentially harmful or toxic substances, such as heavy metals or other contaminants. “But these steps don’t tell you if a dietary supplement will have the intended effects,” Dixon says. “For example, if a supplement is marketed to ‘support digestion,’ how can you tell if it will, in fact, support your digestion?” She says to check out the National Institutes of Health’s Office of Dietary Supplements. “Their dietary supplement fact sheets will give basic information on research regarding a particular supplement.” Now that you know what to look for, here are some of the best supplements for women: Vitamin D Best supplement for women in cold, cloudy climates: vitamin D Live in an area with not a lot of sunlight (most of the U.S. come winter) or slather on sunscreen religiously (hat tip to you!)? You’re likely lacking in vitamin D, as the skin needs sun exposure to produce its own to complement the D you get in your diet in things like fish, eggs, mushrooms, and dairy. Vitamin D supports your bone density, mood, energy, and immune health, says Stephanie Gray, DNP, MS, a functional medicine nurse practitioner and owner of Integrative Health and Hormone Clinic in Iowa. Of course, it also helps you absorb calcium. But the latest research suggests that if your vitamin D levels are normal, adding more won’t improve your health. “Ask your doctor for a vitamin D blood test, and if you’re low, supplement with 1,000 to 2,000 IU per day,” Dixon says. “Don’t take more than 4,000 IU per day, the tolerable upper levels for vitamin D.” Buy it: Pure Encapsulations 25 mcG/1,000 IU Vitamin D3 ($12 for 60, amazon.com) (Photo: Shutterstock) Folate Best supplement for women trying to conceive: folate “Folate supports the healthy development of the fetal brain and spinal column, so your folate needs are high around the time of conception,” Gray says. “Supplementing with bioactive 5 methyltetrahydrofolates [5-MTHF, found in the supplement recommended below] allows for the bypassing of steps in folate metabolism, which may be especially beneficial in those with digestive concerns.” Aim for a minimum of 1,000 mcg if you’re trying to get pregnant.

In addition to supporting eye and brain health, keeping your mood on an even keel, and reducing menstrual pain, they’re vital for pregnant and breastfeeding mothers to help the cognitive development of the child (and to prevent food allergies in the little one, according to the latest research). “Omega-3s have tremendous cardiovascular benefits, may boost your mood, can help reduce insulin resistance, and tame inflammation caused by autoimmune diseases,” Gray says. Discover how to incorporate omega-3s into every meal and consider a supplement if you’re not so fresh on seafood or don’t nosh on a lot of nuts. “When looking for a supplement, choose one that contains both DHA and EPA,” Gray says. “DHA supports optimal hormone signaling and EPA helps decrease inflammation.” Start with a dose of 500 mg per day—after checking with your doctor, of course.

While your body naturally produces glutathione, levels can dip due to stress, aging, and exposure to toxins (hello, air pollution and that extra glass of wine). Because oral glutathione isn’t always well absorbed, look for a liposomal or acetylated form to maximize bioavailability. And don’t forget the glutathione precursors—foods rich in sulfur, like garlic, onions, and cruciferous veggies, help your body make more of its own supply.

As we age, our cells become weaker and more prone to damage, but research shows this recently discovered odd-chain saturated fat can help fortify them, reduce inflammation, and even improve mitochondrial function (aka your body’s energy powerhouses). It also supports the immune system, good gut health and a healthy metabolism. Since modern diets have phased out much of this essential fatty acid (buh-bye, full-fat dairy), a daily dose of Fatty15 helps fill the gap—no butter required. It’s a small but mighty way to nourish your body at the cellular level.
