Natural Iron Supplements and Food Sources
By Dr (TCM) Attilio D'Alberto | Traditional Chinese Medicine Practitioner, Wokingham
Iron deficiency is the most common nutritional deficiency in the world, and women of reproductive age are particularly vulnerable due to menstrual blood loss. In traditional Chinese medicine, iron deficiency maps closely to blood deficiency — a pattern characterised by pallor, fatigue, dizziness, heart palpitations, poor sleep, and scanty or delayed periods. Addressing it through both nutritional and herbal approaches is one of the most impactful things that can be done for women's health and fertility.
Signs of Iron Deficiency
Common symptoms include fatigue and low energy, pallor (pale inner eyelids, nail beds, and gums), cold hands and feet, shortness of breath on exertion, heart palpitations, brittle nails, hair loss, headaches, and difficulty concentrating. In the menstrual context, blood deficiency also produces scanty periods, a pale menstrual colour, a delayed cycle, and a tendency towards anxiety and poor sleep in the premenstrual phase.
Types of Iron
Haem iron — found in animal products (red meat, liver, poultry, fish). This form is absorbed at a rate of 15–35% regardless of the body's iron status, making it the most bioavailable dietary form. Liver is the single richest source of iron and is particularly beneficial for women with heavy periods.
Non-haem iron — found in plant foods (lentils, spinach, chickpeas, pumpkin seeds, fortified cereals). Absorbed at a much lower rate (2–20%) but can be significantly enhanced by consuming vitamin C alongside it.
Best Natural Food Sources
The most iron-rich foods include: beef liver (the highest single source), red meat, sardines and other oily fish, dark leafy greens (spinach, kale, watercress), lentils and chickpeas, pumpkin seeds, tofu, and dark chocolate. In TCM dietary therapy, blood-building foods also include black sesame seeds, red dates (Da Zao), beetroot, black beans, and bone broth.
Iron Supplements
If dietary sources are insufficient or absorption is impaired, iron supplementation may be necessary. Ferrous bisglycinate (iron chelate) is the best-tolerated form — it is well absorbed and causes significantly less gastrointestinal upset than ferrous sulphate, which is the most commonly prescribed form in conventional medicine. A standard supplemental dose is 14–20mg of elemental iron daily for maintenance, or 40–60mg daily for repletion of confirmed deficiency. Taking iron with vitamin C and away from tea, coffee, and dairy maximises absorption.
Chinese Herbal Medicine for Blood Deficiency
Chinese herbal medicine addresses blood deficiency at a systemic level — not just by providing iron but by improving the body's ability to produce, circulate, and store blood. The key blood-building herbs include Dang Gui (angelica sinensis) — the most important blood tonic in Chinese medicine; Shu Di Huang (prepared rehmannia); Bai Shao (white peony); and Gou Qi Zi (wolfberry). The classical formula Ba Zhen Tang (Eight Treasure Decoction) tonifies both qi and blood simultaneously, making it the most commonly used formula for post-menstrual blood deficiency. I prescribe pharmaceutical-grade granules from Sun Ten in Taiwan.
Absorption Inhibitors to Avoid
Tea (including green tea), coffee, dairy, calcium supplements, and antacids all inhibit iron absorption. Avoid these within two hours of iron-rich meals or supplements. Phytates in wholegrains and legumes also inhibit non-haem iron absorption — soaking and sprouting these foods significantly reduces phytate content.
