Iron is one of the most important minerals for women’s health. It supports red blood cell production, oxygen transport, energy levels, and immune function. Women of reproductive age need 18 mg of iron daily — more than double what men require — due to monthly blood loss during menstruation. During pregnancy, that number jumps to 27 mg. Whether dealing with low energy, heavy periods, or a plant-based diet that limits iron-rich foods, a quality iron supplement can fill the gap.

2. Pink Stork Iron for Women — Best Gentle Formula
Pink Stork Iron for Women – 18 mg Non-Constipating Iron Bisglycinate + Vitamin C for Optimal Absorption – Energy, Focus, & Oxygen Supply – PMS, Pregnancy, Postpartum & Perimenopause – 60 Capsules
Iron for Every Stage of Womanhood: From monthly cycles to menopause, women have unique iron needs, yet nearly 40% of women are deficient, leading to low energy, fatigue, lack of focus or concentration, weakness, and cold limbs. Pink Stork Iron with Vitamin C provides 18 mg of gentle Iron Bisglycinate to help maintain healthy iron levels through every stage of life.
Why Iron Matters: Women’s iron needs change throughout life. Monthly cycles can deplete iron stores and leave you feeling tired or run-down. During pregnancy, your body needs nearly twice as much iron to support healthy blood volume and oxygen transport. After childbirth, iron replenishment supports recovery and vitality. Hormonal shifts during perimenopause can cause heavier cycles, while menopause may impact iron metabolism — making balanced iron levels key for sustained energy, focus, and overall wellness.
Immune, Energy, + Cognitive Support: Iron is essential for hemoglobin production, helping transport oxygen throughout the body to support energy, cognitive function, and immune health. Our formula includes Vitamin C for optimal absorption — so your body gets the most from every capsule. We use Iron Bisglycinate, a chelated form known to be non-constipating and easy on digestion — ideal for women who’ve experienced discomfort with traditional iron supplements.
Expert-Backed + Clean Ingredients: Each vegan capsule provides 18 mg Iron Bisglycinate and 50 mg Vitamin C from Acerola Fruit Extract — with no GMOs, gluten, dairy, soy, or artificial ingredients. Just clean, effective nutrition for women’s wellness. Third-party tested for purity and potency in cGMP facilities.
Women-Owned, Women-Focused: Pink Stork is proudly women-owned and run — offering vitamins, supplements, and wellness support designed to help women thrive through every phase of life: PMS, pregnancy, postpartum, perimenopause, and beyond. Created by Pink Stork—trusted by thousands of women seeking natural, effective solutions.
A non-constipating iron supplement specifically formulated for women’s daily needs.

The capsules are small and easy to swallow.

How to Choose the Best Iron Supplement for Women
The most important factor when choosing an iron supplement is the form of iron. Iron bisglycinate (chelated iron) is the gold standard for tolerability — it absorbs well and causes significantly fewer digestive side effects than ferrous sulfate. Ferrous sulfate provides more elemental iron per dose but is more likely to cause constipation and nausea. Heme iron from animal sources absorbs the best of all but is limited to non-vegan products.
Dosage matters and should be guided by your needs. The RDA for menstruating women is 18 mg, but women with diagnosed deficiency often need 45–65 mg under medical supervision. Look for products that include Vitamin C, as it significantly enhances non-heme iron absorption. Avoid taking iron with calcium, coffee, or tea, which can reduce absorption by up to 50%.
Consider the delivery format that fits your routine. Capsules and tablets offer precise dosing and fewer additives, while gummies are easier to take consistently but may contain added sugars. Liquid iron supplements absorb quickly but can stain teeth. Look for GMP-certified manufacturing and third-party testing for quality assurance.
Frequently Asked Questions
How much iron do women need daily?
Women ages 19–50 need 18 mg of iron per day. During pregnancy, that increases to 27 mg. After menopause, the requirement drops to 8 mg per day, the same as men. Women with heavy periods or iron-deficiency anemia may need supplemental doses of 45–65 mg under a doctor’s guidance.
What is the best form of iron for absorption?
Iron bisglycinate (chelated iron) offers the best balance of absorption and tolerability. Heme iron from animal sources absorbs at the highest rate but isn’t available in vegan products. Ferrous sulfate provides a high dose of elemental iron but causes more digestive side effects. Pairing any non-heme iron with Vitamin C can boost absorption by up to 67%.
When is the best time to take iron supplements?
Iron absorbs best on an empty stomach, ideally 1 hour before or 2 hours after meals. If it causes stomach upset, taking it with a small amount of food is fine — just avoid dairy, calcium supplements, coffee, and tea within 2 hours of your iron dose. Taking it with a Vitamin C source like orange juice improves absorption.
Can iron supplements cause constipation?
Yes, constipation is the most common side effect of iron supplements, particularly with ferrous sulfate. Chelated forms like iron bisglycinate and slow-release formulas cause significantly less constipation. Drinking plenty of water and eating fiber-rich foods while supplementing can also help. If constipation persists, switching to a gentler iron form usually resolves it.
How long does it take for iron supplements to work?
Most women notice improved energy within 2–4 weeks of consistent supplementation. However, it typically takes 2–3 months to fully replenish iron stores and normalize ferritin levels. A blood test after 3 months can confirm whether your levels have improved. Continue supplementing for as long as your healthcare provider recommends.
Should I take iron with other supplements?
Take iron with Vitamin C to enhance absorption. Avoid taking iron at the same time as calcium, zinc, or magnesium, as these minerals compete for absorption. If you take a multivitamin with calcium, space it at least 2 hours apart from your iron supplement. B12 and folate are safe to take with iron and actually support red blood cell production.
