When most people think about healthy eating, they imagine protein shakes, carbs, and healthy fats with a side salad. But there’s a hidden world of “micronutrients” — the vitamins and minerals quietly working behind the scenes to keep your body running at its best.
These little powerhouses influence everything from your mood and energy levels to bone strength and hormone balance. The tricky part? Women face unique challenges that can make it harder to get enough of these essential nutrients.
In this article, we dive into everything women need to know about key vitamins and minerals, plus practical tips and strategies to make sure your body is truly nourished from the inside out.
Why Women Are Prone to Deficiencies: 5 Common Hurdles to Optimal Nutrient Intake
Reason 1: Eating Less and Missing Key Vitamins Women Need
Women often eat fewer calories relative to their lean body mass than men. But here’s the catch: even if you’re hitting your calorie goals, skimping on nutrient-rich foods can leave you running low on the vitamins and minerals your body truly needs.¹
Reason 2: Restrictive Diets and Popular Eating Trends That Impact Women’s Vitamins
Vegan, vegetarian, dairy-free, gluten-free, paleo, keto, low-fat, or low FODMAP—these diets are more popular than ever. But here’s the thing: cutting out whole food groups can easily create gaps in your nutrition, especially if you’re not intentional about what you’re replacing.¹
Reason 3: Medications That Can Deplete Women’s Essential Vitamins
Common medications—like the pill, antidepressants, hormone therapy, diuretics, and even some weight-loss medications—can quietly drain your nutrient stores. If this sounds familiar, it’s a good idea to find out which nutrients you might be low in and make small changes to your diet or supplements to keep your body fully nourished.²
Reason 4: Intentional and Unintentional Weight Loss That Affects Vitamins for Women
Nutrient deficiencies can sneak up on you—they can cause unintentional weight loss or show up when you’re intentionally opting for restrictive diets or bariatric surgery. Low nutrient intake, whether from very low-calorie plans, keto diets, or medications like GLP-1 agonists, can also slow your metabolism and make long-term weight management even trickier.³⁻⁵
Reason 5: How Different Life Stages Affect Vitamins for Women
Menstruation, pregnancy, and menopause all place extra demands on your body, meaning your nutrient needs go up. If you’re not intentional about getting enough, deficiencies can sneak in before you even realise it.¹
And if “nutrient deficiency” makes you think of pirates with missing teeth, think again. Modern-day nutrient gaps are much sneakier, but just as important to catch. One simple way to help fill the gaps is with a high-quality multivitamin and mineral supplement, such as Femme Essentials, which is specially designed to provide women with the nutrients they need to feel their best.
5 Essential Vitamins for Women and Why They Matter
Curious about the nutrients women often miss? We’ve highlighted a few key micronutrients below, nutrients you’ll find packed into, Femme Essentials Multivitamin and Mineral designed to support your energy, mood, and overall wellbeing.
Iron: Key Mineral for Women’s Energy, Blood Health, and Oxygen Flow
Iron is like the delivery truck of your bloodstream, carrying oxygen to every cell. Without enough, you may feel drained, foggy, and unable to concentrate. Low iron is incredibly common in women, largely due to monthly menstrual blood loss and higher demands during pregnancy. Many women don’t reach the recommended 18 mg daily.6
How to get it: Red meat, poultry, legumes, leafy greens, and topping up with a multivitamin like Femme Essentials that provides 5mg of iron.
Always consult a healthcare professional before supplementing with iron, as too much can cause its own issues. For more on maintaining healthy iron levels, managing low iron, and choosing the right supplements, explore our 3-part article series on iron:
Iodine for Women: The Essential Mineral That Supports Hormone Balance
Iodine is the biggest nutrient supporter for your thyroid, directing hormone production. Women need about 33% more iodine than men, and requirements double during pregnancy.7 Surveys show many women remain unaware of iodine’s importance for health.8
How to get it: Foods like eggs, milk, prawns, yoghurt, bread, and seaweed (nori) are great sources.
Magnesium & B Vitamins for Women: Natural Stress-Relief Nutrients
Magnesium and B vitamins are like little cushions for your nervous system; they help ease stress, balance your mood, and even soften those frustrating PMS symptoms.
Research shows that pairing magnesium with B6 can significantly calm premenstrual anxiety and support mood balance during menopause.⁹

Simple, Everyday WaWhy Vitamin D Matters for Women: The Sunshine Nutrient for Overall Wellnessys to Boost Kids Immunity Naturally
Vitamin D is your body’s “sunshine vitamin,” made when your skin soaks up sunlight—but surprisingly, many women are still low in it, even in sunny climates. It plays a starring role in keeping your bones strong, supporting fertility, pregnancy, and healthy muscle function.¹⁰⁻¹²
How to boost it: soak up safe sun, enjoy fortified foods, or consider a supplement—especially during pregnancy, breastfeeding, and menopause, when your needs are higher.
Are You at Risk? Common Scenarios That Affect Women’s Vitamin Levels
Life stages like menstruation, pregnancy, and breastfeeding can boost nutrient needs, especially iron.
Restrictive diets—avoiding animal products, grains, or certain carbs—can create gaps in calcium, iron, B12, vitamin D, zinc, magnesium, iodine, and folate.
Medications such as weight-loss treatments, hormone therapy, diuretics, and digestive medication can deplete essential nutrients.
Bariatric surgery can alter nutrient absorption, raising the risk of deficiencies.
Small Nutrients, Big Impact: Essential Vitamins for Women’s Health
Micronutrients may be tiny, but their impact on women’s health is huge. The right vitamins for women can make all the difference—iron keeps your energy flowing, iodine supports hormone balance, magnesium and B vitamins help protect your mood, and vitamin D strengthens bones and muscles for the long term.
