A doctor has issued guidance to Britons who take iron supplements, warning that pairing them with certain foods and drinks could impair their absorption.
The alert concerns iron tablets, taken by millions of people in the UK to help bridge nutritional gaps.
Medical practitioner Dr Suraj Kukadia, who shares health advice online as Dr Sooj, warned that certain dietary items can impair the body's capacity to process the mineral properly.
He specifically warned against consuming iron tablets with milk or other dairy products, which can hinder absorption.

What is iron?
Iron plays a crucial role in producing red blood cells, supporting cellular health, maintaining skin quality and bolstering immune system function.
Although most individuals obtain sufficient iron through their regular diet, some people struggle with proper absorption of the mineral, Dr Kukadia explained.
Sharing his expertise in a TikTok video, Dr Kukadia drew an important distinction between two related but different conditions.
"If you're taking iron supplements, you should probably watch this video," he declared.
"Now, remember, there is a difference between an iron deficiency anaemia and an iron deficiency.
"An iron deficiency is characterised by a low ferritin in the blood, and it's usually caused by a lack of iron in your diet," he explained.
Iron deficiency anaemia represents a more severe condition that develops gradually over the course of several months or years.
The condition manifests through various symptoms, including fatigue, difficulty breathing, lightheadedness, heart palpitations, pallor and headaches.
Unfortunately, those suffering from genuine iron deficiency anaemia cannot resolve their condition through dietary changes alone or with standard over-the-counter supplements.

However, for patients with genuine iron deficiency, Dr Kukadia revealed he typically prescribes a minimum of 200 milligrams of iron per day.
"Ideally, you want to take iron supplements with vitamin C, so orange juice, and avoid taking it with milk and dairy," he advised.
The NHS echoes this guidance, underscoring the importance of proper administration to ensure iron is broken down properly. It instructs patients to "swallow tablets or capsules with a drink of water or juice only".
"Do not take them with milk, as milk stops the iron getting into your system," it adds.
