Introduction

Manganese is an essential trace mineral involved in bone development, metabolism of carbohydrates and fats, antioxidant protection, and nervous system function. Although required in small amounts, manganese is vital for many enzyme-driven processes in the body.

What Is Manganese?

Manganese is a trace mineral that acts as a cofactor for several enzymes involved in metabolism, bone formation, and antioxidant defense.

• Type: Essential trace mineral
• Main role: Enzyme activation and bone health
• Storage: Bones, liver, pancreas, and kidneys

How Manganese Works in the Body

Manganese supports multiple metabolic pathways and is a key component of antioxidant enzymes.

• Supports bone formation and connective tissue health
• Plays a role in carbohydrate, fat, and protein metabolism
• Acts as a component of superoxide dismutase (antioxidant enzyme)
• Supports brain and nervous system function

Sources of Manganese

• Whole grains
• Nuts and seeds
• Legumes
• Leafy green vegetables
• Tea
• Brown rice

Manganese Deficiency

Manganese deficiency is rare but may occur with poor dietary intake or certain digestive disorders.

Possible deficiency symptoms include:

• Weak bones or poor bone development
• Fatigue
• Impaired growth
• Changes in carbohydrate metabolism
• Reduced antioxidant capacity

Dosage & How to Take Manganese

• Adult men: 2.3 mg/day
• Adult women: 1.8 mg/day
• Pregnancy: 2.0 mg/day
• Breastfeeding: 2.6 mg/day
• Upper limit: 11 mg/day

Manganese intake is usually sufficient through a balanced diet.

Forms of Manganese

• Manganese sulfate
• Manganese gluconate
• Manganese citrate
• Chelated manganese

Benefits & Uses

• Supports bone development and strength
• Aids metabolism of carbohydrates and fats
• Provides antioxidant protection
• Supports brain and nerve function
• Helps maintain connective tissue health

Safety, Side Effects & Precautions

• Safe at recommended dietary levels
• Excess intake may affect nervous system health
• High-dose supplements should be avoided
• People with liver disease should use caution

Special Populations

• Elderly: Monitor intake from supplements
• People with bone disorders: Balanced intake important
• Athletes: Supports metabolism and recovery
• Individuals with liver disease: Avoid excess intake
