Low Iron, Heavy Periods and Everyday Fatigue: What Women Need to Know

Plus a nourishing, food-based mineral syrup recipe

Zyzven Naturals  ·  18 September 2026

Feeling constantly tired is often dismissed as part of being busy, raising children, working, experiencing heavy periods or simply getting older. But persistent exhaustion should never automatically be accepted as normal.

Iron is an essential mineral involved in carrying oxygen around the body, supporting muscle function and helping our cells produce the energy needed for everyday life. When iron stores become depleted, the body may struggle long before a person realises what is happening.

At Zyzven Naturals, we believe wellness begins with understanding the body — not covering up its warning signs.

What does iron do inside the body?

Iron is an important component of haemoglobin, the protein in red blood cells that transports oxygen from the lungs to the rest of the body. It is also found in myoglobin, which helps supply oxygen to the muscles.

The body also needs iron for normal growth, neurological development, cellular function and the production of certain hormones.

When iron stores fall too low, symptoms may include:

• Persistent tiredness or lack of energy
• Weakness
• Shortness of breath
• Headaches
• Heart palpitations
• Dizziness or feeling light-headed
• Cold hands and feet
• Difficulty concentrating
• Pale skin or paleness inside the lower eyelids
• Restless legs
• Increased hair shedding
• Soreness at the corners of the mouth
• Unusual cravings for ice or non-food substances

These symptoms are not exclusive to iron deficiency. Thyroid disorders, vitamin B12 or folate deficiency, chronic illness, poor sleep and several other conditions can produce similar symptoms. This is why testing matters.

Iron deficiency and anaemia are not exactly the same

Iron stores may become depleted before haemoglobin falls low enough for iron-deficiency anaemia to be diagnosed.

Equally important, not every case of anaemia is caused by low iron. Anaemia may also be associated with vitamin B12 or folate deficiency, chronic inflammation, infections, heavy bleeding, pregnancy, inherited blood disorders, kidney disease or problems absorbing nutrients.

A healthcare professional may recommend tests such as:

• A full blood count
• Haemoglobin
• Serum ferritin
• Transferrin saturation
• Vitamin B12 and folate
• Additional investigations when blood loss or poor absorption is suspected

Ferritin helps indicate the body's stored iron, although inflammation can sometimes make ferritin appear higher than it otherwise would.

Who is more vulnerable to low iron?

Women with heavy periods

Monthly blood loss increases iron requirements. Women experiencing very heavy, prolonged or painful menstruation — including women living with fibroids — may gradually lose more iron than their diet replaces. Heavy bleeding deserves medical investigation. Replacing iron without addressing the reason for the blood loss is not a complete solution.

Pregnant and postpartum women

Iron requirements increase during pregnancy because the body is producing more blood while supporting the developing baby and placenta. Blood loss during childbirth and the demands of postpartum recovery may also affect iron levels. Supplementation should be discussed with a qualified healthcare professional.

Children and teenagers

Growth increases the body's nutritional demands. Menstruating teenagers, children with restricted diets and young people who regularly miss balanced meals may be particularly vulnerable. Children should never be given iron supplements or concentrated herbal tonics without appropriate professional advice.

Vegetarians and vegans

Plant foods contain non-haem iron, which is generally absorbed less efficiently than haem iron. A plant-based diet can provide iron, but food selection, variety and absorption strategies require attention.

Frequent blood donors

Regular blood donation removes iron-containing red blood cells. Frequent donors may need their iron status monitored.

People with digestive or chronic health conditions

Coeliac disease, inflammatory bowel disease, previous gastrointestinal surgery, chronic inflammation and some other conditions can affect iron absorption or utilisation.

Iron-rich foods to include regularly

A food-first approach can help support everyday iron intake.

Plant-based sources include:

• Lentils
• Chickpeas
• Kidney beans and white beans
• Tofu and tempeh
• Pumpkin seeds
• Cashews
• Fortified breakfast cereals
• Iron-fortified breads
• Kale, watercress and other dark-green vegetables
• Dried apricots, prunes and raisins
• Peas
• Potatoes with the skin
• Blackstrap molasses, depending on the product

People who eat animal products may also obtain iron from meat, poultry, fish and shellfish. Always check food labels because iron content can vary considerably between products.

Help your body absorb plant-based iron

Plant-based iron is better absorbed when eaten alongside vitamin C. Try combining:

• Lentils with tomatoes and peppers
• Beans with lime or lemon
• Fortified cereal with berries
• Tofu with broccoli
• Leafy vegetables with citrus dressing
• Chickpeas with tomatoes and fresh parsley

Tea, coffee, cocoa and large amounts of calcium may reduce iron absorption when consumed at the same time as an iron-rich meal or iron supplement.

This does not mean you must abandon your tea. If your iron is low, consider leaving some space between your iron-rich meal or supplement and tea, coffee or calcium supplements. Follow the directions given by your healthcare professional or on the product label.

Zyzven Nourishing Mineral Syrup

This homemade recipe is intended as a nourishing food preparation. It is not a standardised iron supplement and should not be used to treat diagnosed iron deficiency or anaemia. The amount of naturally occurring iron will vary according to the ingredients and brands used.

Storage and use

Keep refrigerated and use within seven days. Alternatively, freeze small portions in a clean ice-cube tray and defrost only what is needed. Discard the syrup if it develops mould, bubbling, an unusual smell or any sign of fermentation.

Adults may use one to two teaspoons as a food:

• Stirred into porridge
• Mixed into plain yoghurt
• Added to a smoothie
• Diluted in warm water
• Drizzled over fruit

Because this recipe contains naturally occurring sugars and concentrated molasses, it may not be suitable for everyone — particularly people managing diabetes or blood-glucose concerns.

When food may not be enough

Diet is an important foundation, but someone with confirmed iron-deficiency anaemia may require a measured iron supplement and investigation into the underlying cause.

Supporting your wider wellness routine

Food, appropriate testing and professional guidance remain central when low iron or anaemia is suspected. Herbal teas can nevertheless become part of a consistent daily wellness routine.
