Your Bone and Cartilage Builder
Manganese is a trace mineral needed for building bones and cartilage, metabolizing carbohydrates and amino acids, and running the mitochondrial antioxidant enzyme (MnSOD). It's less well-known than other minerals but plays essential structural and metabolic roles.
What is Manganese?
Manganese is an essential trace mineral. It's a cofactor for enzymes involved in bone formation (glycosyltransferases), antioxidant defense (MnSOD), and carbohydrate metabolism. Blood levels are not very reflective of total body stores.
↑ What High Manganese Means
Manganese toxicity primarily affects the brain (manganism—resembles Parkinson's disease). Usually from occupational exposure (welding, mining) or contaminated water, not supplements.
Common symptoms:
Tremor · Slow movement (bradykinesia) · Facial masking · Psychiatric symptoms · Resembles Parkinson's disease
↓ What Low Manganese Means
Very rare from dietary deficiency alone. Can contribute to poor bone formation, impaired glucose metabolism, and reduced antioxidant capacity.
Common symptoms:
Poor bone development (rare) · Impaired glucose tolerance · Skin rash
Why It Matters
When normal:
Bone and cartilage formation
Mitochondrial antioxidant (MnSOD)
Carbohydrate and amino acid metabolism
Wound healing
Risks if abnormal:
Deficiency: rare, impaired bone formation
Toxicity: manganism (neurological damage resembling Parkinson's)
Toxicity usually occupational, not dietary
What Can Cause Abnormal Levels?
Occupational Exposure (high)
40% likelyWelding, mining, and battery manufacturing expose workers to manganese fumes.
Contaminated Water (high)
30% likelySome groundwater has high manganese concentrations.
Liver Disease (high)
The liver clears manganese. Cirrhosis causes accumulation.
TPN Without Manganese
Total parenteral nutrition without manganese causes deficiency in hospitalized patients.
What You Can Do
Manganese foods: whole grains, nuts, legumes, tea, leafy greens, pineapple
Impact: Dietary deficiency is extremely rare with varied diet \u00B7 Timeline: 4-8 weeks
If lifestyle changes aren't enough:
Supplementation rarely needed—most multivitamins contain adequate amounts
Impact: Prevents deficiency \u00B7 Timeline: Ongoing
Recommended retest: 6 months; sooner if occupational exposure
