Iron is key to mood and mental health as it plays a key role in oxidative metabolism and the reduction of free radicals. It is also a cofactor in the synthesis of neurotransmitters and myelin. Your neurotransmitters are serotonin, dopamine, beta-endorphins, and GABA.
Specifically, iron plays an important role in how your body makes the neurotransmitters called serotonin, dopamine and norepinephrine – all of them important in mental health. Research suggests a connection between low iron levels and symptoms of depression, anxiety, and schizophrenia, Levin and Gattari write.
You also may feel grumpy, have headaches, and have trouble concentrating. Most people begin to feel normal after a few weeks of taking iron pills. But you need to take the pills for several months to build up the iron supply in your body.
Iron deficiency anemia and depression
According to a 2020 study , iron deficiency anemia can increase a person's risk of depression. Iron deficiency can cause low levels of serotonin, an important neurotransmitter and mood stabilizer.
And since iron is an essential element for brain functions that can dictate psychological behaviours, low iron levels in the body may put you at risk for a variety of mental health issues such as anxiety and depression.
And since iron is an essential part of the systems and circuits in the brain that can dictate psychological behaviors, low iron levels in the body may make you more at risk for anxiety and depression.
Not only does anemia reduce your energy levels, but it can also affect the way you think and feel. Anemia, particularly the iron deficiency kind, has been linked to mental health conditions like depression and anxiety.
Iron gives you energy because it allows your tissues, muscles and cells to receive and absorb oxygen.
Iron is an important Co Factor for serotonin production as it is involved in the conversion of tryptophan into 5HTP, and 5HTP to serotonin.
However, even low-grade iron deficiency can lead to more immediate cognitive or neurological symptoms, such as fatigue, trouble concentrating or dizziness. Lack of iron has also been associated with memory and attention problems, as well as poor cognitive development in children.
Iron pills don't work for everyone, but they do help support energy levels and reduce feelings of tiredness and fatigue. The body needs iron to produce red blood cells which carry oxygen around the body. If you experience ongoing tiredness and fatigue, consider taking an iron supplement such as Active Iron.
People with symptoms of iron deficiency may feel more energetic and less tired during exercise once iron pills start working. Once the iron level is restored and hemoglobin levels rise, symptoms of iron deficiency resolve.
You may notice pale skin and cold hands and feet. Iron-deficiency anemia can also cause you to feel dizzy or lightheaded. Occasionally, it can cause chest pain, a fast heartbeat and shortness of breath. Iron deficiency can cause you to have unusual cravings for non-food items such as ice, dirt or paper.
Iron is important for healthy brain development and growth in children, and for the normal production and function of various cells and hormones.
– It usually takes 2 to 3 weeks of taking regular iron supplements before your symptoms start to improve. – You may need to keep taking iron for several months to build up your iron reserves and keep your anemia from returning. Take your pills for as long as your doctor recommends, even if your symptoms have improved.
Iron affects synthesis and signaling of the neurotransmitters dopamine, noradrenalin, adrenaline and 5-hydroxytryptamine, which are involved in emotion, attention, reward, movement, and various other functions.
Extreme fatigue and exhaustion “Fatigue is one of the most common signs of iron deficiency because it means your body is having trouble carrying the oxygen to your cells so it's affecting your energy levels,” Thayer says. People lacking enough iron in their blood often feel sluggish, weak, and unable to focus.
Experts believe that increasing your iron intake may give you more energy if your iron stores are low, even if your haemoglobin (the part of your red blood cells that carries oxygen) levels are above the cut-off for anaemia.
When you have iron deficiency anaemia, you don't have enough haemoglobin to do its thing. Without enough oxygen circulating around your body, you feel exhausted. Taking iron tablets - when you have iron deficiency anaemia - boosts your haemoglobin levels, thus giving you that much-needed extra energy.
Deficiency of iron is reported to cause several behavioural disturbances in children. These children are irritable, disruptive, have a short attention span and lack interest in the surroundings.
Anemia itself can also cause anxiety as a symptom. Those that are anemic are placing their body under a great deal of stress, and this often sends messages to the brain to be more anxious.
Low iron intake resulting from diet and accelerated iron loss, which occurs through bleeding or breastfeeding, are the main causes of iron deficiency. The first symptoms of iron deficiency anemia tend to be neurological resulting in brain fog and fatigue.
You may also find that low iron causes weight gain. There are a couple of reasons for this; firstly, your energy levels are low and so your exercise levels reduce; secondly, iron is essential for thyroid function, and an underactive thyroid will lead to weight gain.
When your body isn't getting enough oxygenation due to a lack of iron, you may find it hard to maintain focus and carry out your daily tasks. In addition, you may experience mood swings and irritability. Over time, in some cases, it may cause anxiety and depression.
