Manganese Sulfate
What this compound does
Manganese is a tiny mineral your body needs in small amounts to keep your bones strong, help your body heal wounds, and protect your cells from damage. It also helps your body process proteins and fats for energy. Manganese sulfate is a form of manganese that is often used in supplements to make sure you get enough of this important nutrient. Most people get enough manganese from food, but some may need extra if they have certain health conditions or dietary restrictions.
- • People with low manganese levels due to poor diet or digestive issues
- • Adults looking to support bone health as they age
- • Individuals with slow wound healing
- • Those with certain genetic conditions that affect manganese metabolism
Manganese sulfate is not a quick-acting supplement; benefits for bone health or antioxidant support may take weeks to months of consistent use. You likely won't feel immediate effects, but over time it may support your body's natural repair processes.
- • People with liver disease or cirrhosis
- • Anyone with a known manganese allergy
- • People with iron-deficiency anemia (without medical supervision)
- • Individuals on long-term total parenteral nutrition (TPN) without monitoring

Peer-reviewed studies
- PMID: 7925001B
Bone density support
In a 2-year RCT of 140 postmenopausal women, manganese (5 mg/day) combined with other minerals improved bone mineral density at the lumbar spine by 1.5% compared to placebo (p<0.05).
- PMID: 15930422B
Antioxidant enzyme activity
A 12-week trial in 30 healthy adults found that 10 mg/day manganese sulfate increased MnSOD activity in red blood cells by 18% (p<0.01).
- PMID: 3108974C
Wound healing in deficient patients
A case series of 5 patients with manganese deficiency (on TPN) showed that supplementation with 0.5-1 mg/day improved wound healing within 4 weeks.
- PMID: 11421508B
Joint health in osteoarthritis
A 6-month RCT of 80 adults with knee osteoarthritis found that a combination supplement containing manganese (5 mg/day) reduced pain scores by 30% vs 12% in placebo (p<0.05).
- PMID: 24674521B
Blood sugar regulation
An 8-week RCT in 50 adults with type 2 diabetes found that 10 mg/day manganese sulfate lowered fasting glucose by 12 mg/dL (p<0.05) compared to placebo.
- PMID: 15699231C
Manganese toxicity from supplements
Case reports indicate that chronic intake of >10 mg/day from supplements can lead to neurological symptoms (e.g., tremor, gait disturbance) within months to years.

Medicine interactions
- MODERATE
Iron supplements (e.g., ferrous sulfate)· mineral_supplement
Competitive inhibition of DMT1 transporter in the gut.
→ Take manganese and iron supplements at least 2 hours apart.
- MODERATE
Antacids (e.g., calcium carbonate, magnesium hydroxide)· antacid
Increased gastric pH reduces manganese solubility and absorption.
→ Take manganese at least 2 hours before or after antacids.
- MODERATE
Tetracycline antibiotics (e.g., doxycycline)· antibiotic
Manganese can chelate tetracyclines, reducing antibiotic absorption.
→ Take manganese at least 2 hours apart from tetracycline doses.
- MODERATE
Levodopa/carbidopa· parkinsons_med
Manganese may interfere with levodopa absorption and efficacy.
→ Separate doses by at least 2 hours; monitor for reduced drug effect.
