Top Food Sources of Manganese ✓
Function: Antioxidant defense, metabolism
(a transition metal)
Manganese is a trace mineral essential for bone development, metabolism of carbohydrates and amino acids, and antioxidant defense. Though needed in small amounts, it supports many enzyme functions and contributes to overall cellular health.
Supports Bone Formation – Manganese is crucial for healthy bone structure and development, especially in combination with calcium, zinc, and copper.
Involved in Antioxidant Defense – As part of the enzyme manganese superoxide dismutase (MnSOD), it helps neutralize harmful free radicals in cells.
Essential for Enzyme Function – Acts as a cofactor for numerous enzymes involved in metabolism of carbs, amino acids, and cholesterol.
Important for Wound Healing – Manganese contributes to collagen production and blood clotting, both of which are critical in the wound healing process.
Supports Brain and Nerve Function – Plays a role in neurotransmitter synthesis and nerve cell function, indirectly supporting mood and cognitive health.
Assists in Glucose and Energy Metabolism – Helps regulate blood sugar levels by supporting enzymes that manage glucose metabolism.
Absorption Affected by Other Nutrients – High iron, calcium, or phosphorus intake may reduce manganese absorption, as they compete in the gut.
Stored in Bones, Liver, and Kidneys – Most manganese in the body is stored in these organs, with the rest involved in active metabolic processes.
Deficiency is Rare – Manganese deficiency is uncommon but may impair bone health, growth, or glucose metabolism if it occurs.
Toxicity Possible with Overexposure – Excessive intake, especially from inhaled sources or unregulated supplements, can affect the nervous system.
