Manganese Deficiency: Symptoms and Treatments

Written by Medicover Team and Medically Reviewed by Dr Prashant Manohar Gaikwad , Endocrinologists



Manganese is a trace mineral that plays an important role in many biological processes in the human body. It supports enzyme activity, bone development, metabolism, and antioxidant defense. Although manganese deficiency is uncommon, inadequate levels can affect several body systems and lead to health complications.

Understanding the symptoms, causes, and treatment options for manganese deficiency can help identify the condition early and restore proper nutrient balance.


What Are the Types of Manganese Deficiency?

Manganese deficiency may appear in different forms depending on the underlying cause and the systems affected.

  • Dietary manganese deficiency caused by inadequate intake of manganese-rich foods
  • Malabsorption-related deficiency due to digestive disorders
  • Genetic manganese metabolism disorders affecting manganese transport in the body
  • Secondary deficiency linked to chronic illnesses or metabolic conditions

What Are the Symptoms of Manganese Deficiency?

The symptoms of manganese deficiency may be subtle and can vary depending on the severity of the deficiency. Since manganese supports bone health, metabolism, and neurological function, a deficiency can affect several areas of the body.

  • Weak bones or skeletal deformities
  • Increased risk of osteoporosis and fractures
  • Impaired glucose tolerance
  • Fatigue or weakness
  • Mood changes or irritability
  • Memory loss or difficulty concentrating
  • Poor coordination or balance issues
  • Skin rashes or dermatitis
  • Slow wound healing

Causes of Manganese Deficiency

Manganese deficiency can occur when the body does not receive enough manganese from the diet or when absorption and metabolism of the mineral are impaired.

  • Low intake of manganese-rich foods such as nuts, whole grains, and leafy vegetables
  • Gastrointestinal conditions such as Crohn's disease or celiac disease
  • Chronic diarrhea affects nutrient absorption
  • High intake of phytates or oxalates that reduce manganese absorption
  • Genetic mutations affecting manganese transport and metabolism

When Should You See a Doctor for Manganese Deficiency?

Medical advice should be sought if symptoms of nutrient deficiency persist or worsen. Consult an Endocrinologist if these symptoms persist:

  • Persistent bone weakness or frequent fractures
  • Unexplained skin problems or slow wound healing
  • Neurological symptoms such as memory loss or coordination issues
  • Signs of metabolic problems, such as impaired glucose tolerance

Diagnosis of Manganese Deficiency

Diagnosing manganese deficiency usually involves laboratory testing along with clinical evaluation and dietary assessment.

  • Blood tests to measure manganese levels
  • Hair or tissue mineral analysis for long-term manganese status
  • Clinical evaluation of symptoms and medical history
  • Dietary assessment to identify inadequate nutrient intake

Treatment for Manganese Deficiency

Treatment focuses on restoring normal manganese levels and addressing the underlying cause of the deficiency.

  • Increasing intake of manganese-rich foods such as nuts, seeds, whole grains, and leafy vegetables
  • Manganese supplements are prescribed under medical supervision
  • Treatment of underlying gastrointestinal disorders affecting nutrient absorption
  • Dietary planning to improve overall nutrient balance
  • Regular monitoring of manganese levels during recovery

  • Gradual improvement after increasing manganese intake
  • Monitoring of nutrient levels through follow-up tests
  • Management of underlying digestive or metabolic conditions
  • Maintaining a balanced diet to prevent recurrence
