Best Vitamins and Supplements for Women in 2026

Nature Made makes some of the most affordable vitamins available. The Nature Made women's multivitamin includes 23 nutrients essential for women, including 100% of the recommended daily value of iron. Iron is one of the most common deficiencies in women, especially when pregnant or menstruating. 

With Nature Made, you get over the recommended value of vitamin C, D3 and E, as well as minerals zinc, copper and chromium. So if you are not deficient in those areas, you could get too much of them. Consuming too much vitamin D or E can result in toxicity. 

Nature Made doesn't have the additional bells and whistles other options on the list do, like probiotics. It's a dependable multivitamin that established a name for itself long ago. You also can get Nature Made multivitamins for women at every stage of their life -- prenatal, postnatal and over 50. You can trust the quality of Nature Made because all products are third-party tested and USP-verified. 

Taste is one of the most important factors when deciding which gummy multivitamin is best for you. Because of this, many of the gummy vitamins available are packed full of sugar. Olly women's gummy multivitamins are one of the lowest in sugar, with 2 grams per serving. Don't worry; that doesn't affect the flavor. Even without the added sugar, customer reviews sing praise for how they taste. That's why Olly is the best gummy multivitamin for women. 

The serving size is 2 gummies each day and delivers 18 essential nutrients, including must-haves like vitamins A, C, D, E, B, and calcium and iodine. Olly also includes biotin, which targets skin health. These gummies also do not include any artificial ingredients and are gluten-free. Olly's gummy multivitamins are NSF-certified. The NSF is a third-party testing organization that ensures the quality of supplements.

Before committing to Olly gummy multivitamins, you should consider that they don't contain iron. If you're iron deficient, this isn't the gummy for you. They're also not suitable for vegetarians or vegans as they contain gelatin. 

When I (Nasha) started preparing for my egg freezing journey, I knew I wanted more than a basic prenatal. I landed on Bird&Be Power Prenatal because it offers more than the standard formula for prenatals. It truly was designed with fertility and preconception in mind. Each daily pack includes prenatal, docosahexaenoic acid and other science-backed antioxidants like CoQ10 and N-acetyl cysteine, which have been shown in studies to support egg health and cellular function. You also get bioavailable forms of folate, choline and iron, which means your body can actually absorb and use them effectively. These vitamins are also third-party tested for purity and potency. I also appreciate that it was formulated by fertility doctors, so I felt confident that the quality is top-notch and the dosage is effective.

A few months into taking these prenatals, I noticed real changes. My cycle has become more regular, my PMS symptoms have eased up, and I feel like my body is getting the support it lacked. The pack makes it easy to stay consistent, and the clean, bioavailable ingredients (no fillers, gluten or artificial dyes) give me peace of mind. If you're prepping for egg freezing, IVF or trying to conceive, I recommend these from personal experience.

After years of testing and researching women's health supplements, I've found PCOS support often requires a comprehensive approach. Ideally, one that goes beyond blood sugar balance or cycle regulation. FullWell's Alpha Inositol Plus is formulated to support egg quality, hormone balance and insulin sensitivity, which are all key concerns for people with PCOS.

This supplement combines myo-inositol and D-chiro-inositol, two naturally occurring compounds that have been shown in clinical studies to improve ovulatory function and metabolic markers in women with PCOS. The combination of inositol helps regulate insulin (a hormone that plays a major role in how PCOS manifests), while also supporting more regular cycles. FullWell also includes antioxidants that promote glutathione production, which protects reproductive cells from oxidative stress and may help improve egg quality over time.

I personally like the orange cream flavor; it's reminiscent of orange pop soda, but with added goodies to keep your reproductive system healthy.

Flo's PMS gummies have become a staple in my monthly supplement rotation. They are delicious and backed by ingredients with clinical relevance for hormone-related symptoms like mood swings, bloating and breakouts.

Each serving includes chasteberry (also known as Vitex), which is widely studied for its impact on luteal phase hormone regulation. Chasteberry can help reduce PMS symptoms like irritability and breast tenderness. The gummies also have vitamin B6, which plays a crucial role in neurotransmitter synthesis (like serotonin) and has been shown to support mood balance during premenstrual phases.

I always say that consistency is what makes PMS products effective, and FLo makes it easy with a product that tastes more like a treat. If your PMS symptoms are creeping in and you're looking for an over-the-counter option, this is a great place to start.

Post-menopausal women don't need as much iron as younger women but need more calcium and vitamin B6. Thorne is the best multivitamin for women over 50, thanks to its hefty vitamin content and various certifications that promise quality. Included are several key vitamins like biotin, magnesium and calcium. Thorne says the magnesium and calcium included are in a highly absorbable form. Thorne includes the antioxidant lutein, which is essential for eye health. Iron is not included in the vitamin. 

Thorne women's multivitamin does not include any artificial colors or flavors. It's also gluten, soy and dairy-free. The facilities that produce Thorne multivitamins are third-party certified and NSF Certified for Sport. Additionally, they have an "A" rating from the Therapeutic Goods Association, an Australian Department of Health regulatory agency.

I want to point out that Thorne multivitamins are a little more expensive than other options at $46 for 180 capsules. However, you can subscribe and save 20% on your orders. You have to manage six tablets a day, which is more than some want.

Something that's not talked about enough is the vaginal microbiome. And it's important that we do because it's deeply intertwined with our gut health, hormones and even our immune system. Evvy was developed with specific strains to support the unique link between the vagina, gut and urinary microbiome.

At the core of the formula is a blend of clinically studied Lactobacillus strains, including UREX duo (L. reuteri RC-14 and L. rhamnosus GR-1), which have been extensively researched for their role in maintaining vaginal balance. The probiotic also includes L. crispatus, a dominant strain in a healthy vaginal ecosystem, and postbiotic tributyrin to support gut barrier function. Vitamin D3 and E are also provided to support immunity and reduce inflammation. The patented delayed capsules ensure more live cultures survive the journey to the gut.

Whether you are dealing with recurring imbalances or just want to be proactive about microbiome health, this daily supplement offers a science-backed way to do so. While many probiotics seem like a one-size-fits-all, Evvy's formula is clearly built for people navigating the nuanced realities of vaginal and gut health.

A single month's worth of supplements costs $55, but if you subscribe, you'll save 20%, bringing your cost down to $44.

Made without GMOs, pesticides or harmful chemicals, Garden of Life is the best vegan multivitamin for women. It has 15 vitamins and minerals formulated from whole foods to support your heart health and metabolism. It also promotes healthy skin and nails.

If you're someone who doesn't want to manage multiple doses, you'll be happy to know you only have to take one tablet each day. Additionally, Garden of Life multivitamins are USDA organic-certified, vegan and NSF certified.

It only has 14% of recommended iron, which is pretty low, especially considering many vegetarians have an iron deficiency. If you don't get the proper iron intake from your diet, you likely will need an additional supplement. Garden of Life will put you over the daily recommended limit for other vitamins such as vitamin B6 or B12. You can have too much of a good thing when it comes to vitamins, so it may not be the best choice unless you're truly deficient in the elevated areas.

Iron is a crucial nutrient for women, especially when menstruating. Optimum Nutrition Opti-Women multivitamins offer 100% of the recommended amount of iron. It also includes a large amount of vitamin C, which our bodies need to absorb iron. That's why Optimum Nutrition takes the spot for the best multivitamin with iron. 

You also get 23 vitamins and minerals in this supplement, including calcium and folic acid. Unlike other options, antioxidants and antiinflammatories that support bone and immune health are also included. Optimum Nutrition multivitamins are third-party tested, Informed-Sport certified and made in cGMP-registered and Informed Choice facilities. It's one of the most heavily certified multivitamins on the list.

There are a few things to consider before you start taking Optimum Nutrition multivitamins. The herbal ingredients included can interact with some medications. Some reviews did note a skin rash after taking it. Talk to your doctor to ensure your medications won't interact.
