Natures Aid Iron Bisglycinate Elemental 14mg 90 tablets

Is Iron Bisglycinate Supplement Right for You?

Iron is one of the most important minerals your body needs, yet it's also one of the most commonly lacking nutrients in the UK diet. The NHS estimates that iron deficiency is the most widespread nutritional deficiency worldwide, affecting energy levels, concentration, and the normal formation of red blood cells. If you've been feeling unusually tired, pale, or short of breath, low iron could be a contributing factor. Iron bisglycinate supplement in this gentle, low-dose format from Natures Aid offers a well-tolerated way to top up your intake without the harsh digestive side effects often linked to standard iron tablets. You can browse the full range of supporting nutrients in our vitamins and supplements collection.

Each tablet provides 14mg of elemental iron in the bisglycinate form — a chelated iron that is bound to two glycine amino acids. This 90-tablet pack represents a three-month supply at the standard one-tablet-per-day dose, making it a practical and cost-effective option at just £9.95.

How Does Iron Bisglycinate Work in the Body?

Iron bisglycinate works differently from conventional iron salts like ferrous sulphate. Because the iron is chelated — essentially wrapped in amino acids — it resists binding to other compounds in the gut that would otherwise block absorption. Here's how the process unfolds:

• The chelated iron passes through the stomach largely intact, protected from inhibitors like phytates and tannins found in food.
• It is absorbed through the intestinal wall via a different pathway to non-chelated iron, which reduces competition with other minerals.
• Once absorbed, iron is incorporated into haemoglobin in red blood cells, supporting oxygen transport throughout the body.
• Iron also contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue, as recognised by the European Food Safety Authority (EFSA).

Because less unabsorbed iron remains in the gut, the risk of constipation, nausea, and stomach cramps is considerably lower than with higher-dose iron salts.

Who Should Consider Taking This Iron Supplement?

This supplement is designed for adults and young people over 12 who need to maintain or restore adequate iron levels. It is particularly relevant if you fall into one of the following groups:

• Women with heavy menstrual periods, who lose iron regularly each month
• Vegetarians and vegans, whose diets may be lower in haem iron (the form found in meat)
• Pregnant women or those planning a pregnancy, as iron requirements increase significantly
• People recovering from illness, surgery, or blood loss
• Those who feel persistently tired or fatigued without an obvious cause

It is not intended to treat diagnosed iron deficiency anaemia, which requires medical assessment and often higher-dose prescription iron. If you suspect anaemia, please speak to your GP before self-supplementing.

Is Iron Bisglycinate Suitable for Vegans and How Should It Be Stored?

Natures Aid Iron Bisglycinate tablets are suitable for vegetarians and vegans, as the capsule shell and excipients are plant-based. If you follow a plant-based diet and are concerned about your iron intake, this iron bisglycinate supplement fits neatly into a vegan lifestyle. Women in particular may find it useful alongside other women's health supplements to support overall wellbeing.

Store the tablets below 25°C in a dry place, away from direct sunlight and moisture. Keep the container tightly closed and out of reach of children. Do not use after the expiry date printed on the packaging.

This product is a food supplement, not a medicine. However, speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is Natures Aid Iron Bisglycinate and What Is It Used For?

Natures Aid Iron Bisglycinate Elemental 14mg is a food supplement providing chelated iron to help maintain normal iron levels in adults and adolescents over 12. Iron is an essential mineral that the body cannot produce on its own — it must come from diet or supplementation. The NHS confirms that iron plays a key role in making red blood cells, which carry oxygen around the body, and that a lack of iron can lead to iron deficiency anaemia, causing symptoms such as tiredness, weakness, and shortness of breath.

This supplement is intended for people who may not get enough iron from their diet alone, or who have increased iron requirements. It is not a treatment for diagnosed anaemia — if you have been told by a doctor that you have iron deficiency anaemia, you will likely need a higher-dose prescription iron preparation.

What Do You Need to Know Before Using Iron Bisglycinate?

Before starting any iron supplement, it's worth checking whether it's appropriate for you. Do not take this supplement if any of the following apply:

• You have haemochromatosis (iron overload disorder) or another condition causing excess iron storage
• You have a known hypersensitivity to any ingredient in the tablet
• You are under 12 years of age
• You have been advised by a doctor to avoid iron supplements
• You have active inflammatory bowel disease — seek medical advice first

Iron supplements can interact with several medicines and nutrients. The following interactions are clinically recognised:

• Antacids and proton pump inhibitors — may reduce iron absorption; take iron at least two hours apart
• Tetracycline and quinolone antibiotics — iron can reduce antibiotic absorption; separate doses by at least two hours
• Levothyroxine (thyroid medication) — iron can impair absorption; take at least four hours apart
• Calcium supplements and dairy — calcium competes with iron for absorption; avoid taking together
• Vitamin C — enhances non-haem iron absorption; taking together may be beneficial

How Should You Use Natures Aid Iron Bisglycinate?

Using this supplement correctly makes a real difference to how well your body absorbs the iron. Follow these steps for best results:

1. Take one tablet daily — do not exceed this dose unless directed by a healthcare professional.
2. Swallow the tablet whole with a full glass of water.
3. Take with or shortly after food to reduce the chance of stomach discomfort.
4. Avoid taking alongside tea, coffee, dairy products, or calcium supplements, as these inhibit iron absorption.
5. If you are taking any prescription medicines, check with your pharmacist about the best timing.

The NHS recommends that adults need 8.7mg of iron per day (men and post-menopausal women) and 14.8mg per day for women of reproductive age. This supplement provides 14mg elemental iron, which sits within the nutritional reference range for most adults.

What Are the Possible Side Effects of Iron Bisglycinate?

Iron bisglycinate is widely regarded as one of the gentler forms of supplemental iron. That said, some people may still experience mild effects, particularly when first starting supplementation. If you're also managing digestive concerns, it may be worth exploring our IBS and cramps collection for additional support.

Common side effects (may affect some users):

• Dark or black stools — this is harmless and expected with iron supplementation
• Mild nausea, particularly if taken on an empty stomach
• Constipation or changes in bowel habits
• Stomach discomfort or bloating

Less common side effects (affect fewer users):

• Diarrhoea
• Heartburn or acid reflux
• Metallic taste in the mouth
• Allergic reaction (rash, itching, swelling) — stop use immediately and seek medical advice

Iron bisglycinate typically causes fewer gastrointestinal side effects than ferrous sulphate or ferrous fumarate, which is one reason it is often chosen by people with sensitive stomachs.

How Should You Store Natures Aid Iron Bisglycinate?

Correct storage keeps the tablets effective for their full shelf life. Follow these guidelines:

• Store below 25°C in a cool, dry place
• Keep away from direct sunlight and sources of heat or moisture
• Keep the lid tightly closed after each use
• Store out of sight and reach of children — iron overdose in young children is a medical emergency
• Do not use after the expiry date printed on the base of the bottle
• Do not transfer tablets to another container
