New reports confirm that a widespread deficiency could be causing low moods for millions this winter. Dr. Sermed Mezher, a specialist in nutrition, has highlighted that iron deficiency affects over one billion people globally, potentially leading to feelings of sadness as colder temperatures set in.
As winter blankets many parts of the world, emotional wellbeing often takes a hit. While Seasonal Affective Disorder (SAD) is commonly recognized as a factor, Dr. Mezher warns that a lack of iron might be a significant underlying cause for many individuals feeling downcast this season. In a recent TikTok video, he explained how low iron levels can disrupt dopamine production—the hormone linked to feelings of happiness and reward.
Dr. Mezher stated, “Low iron is the most common nutritional deficiency in the world, affecting more than one billion people.” He elaborated on how this deficiency can impair the brain’s pathways related to dopamine, which play crucial roles in mood regulation, self-control, and social behavior. “It’s no surprise, then, that in iron deficiency, there’s dysfunction in pathways related to dopamine that control feelings of happiness,” he said.
Fortunately, this issue can be addressed. Dr. Mezher emphasized that replenishing iron stores can restore normal dopamine function. He suggests combining iron supplements with vitamin C to enhance absorption and avoiding caffeine intake for two hours before and after iron supplementation.
The NHS lists symptoms of iron deficiency anemia, including fatigue and mood swings. If you suspect you might be affected, consulting your GP for blood tests is crucial. Dietary changes can significantly impact iron levels; foods rich in iron include red meat, leafy greens, and fortified cereals. However, the NHS warns against excessive consumption of certain foods and drinks, such as tea and coffee, which can hinder iron absorption.
Dr. Mezher recommends that individuals take 17 mg or less of iron supplements daily unless advised otherwise by a healthcare professional. “The good news, though, is that when your iron stores are replenished, these pathways return to normal function,” he reiterated.
With the winter months upon us, understanding the link between iron deficiency and mood could be pivotal for many struggling with low spirits. The urgency to address this deficiency is clear, as it holds the potential to significantly improve emotional health for millions during the darker days of the year.
