The Short Answer
Manganese bisglycinate is a chelated form of manganese bound to two glycine amino acids for enhanced absorption. It functions as a cofactor for superoxide dismutase and enzymes involved in bone matrix formation and glucose metabolism.

Health Benefits
Supports bone health by aiding in the formation of connective tissue, crucial for maintaining strong bones and joints. It enhances calcium absorption. - Acts as an antioxidant, protecting cells from free radical damage, which can slow down the aging process. - Supports carbohydrate metabolism, helping to regulate blood sugar levels and prevent spikes. - Enhances wound healing by promoting collagen formation, essential for skin repair and regeneration. - Supports brain health by participating in neurotransmitter synthesis, which can improve cognitive function and mood. - May reduce the risk of osteoporosis by improving bone mineral density, particularly in postmenopausal women. - Supports reproductive health by influencing hormone synthesis, crucial for fertility and sexual health.
Origin & History
Natural habitat
Manganese bisglycinate is a chelated form of manganese, where manganese is bound to the amino acid glycine. This form is synthesized to enhance the bioavailability and absorption of manganese, making it an effective supplement for supporting bone and connective tissue health.
“Manganese has been recognized for its role in bone health since the 20th century. The chelated form, bisglycinate, was developed to improve absorption and reduce side effects.”Traditional Medicine
Scientific Research
Emerging research, including some human trials, suggests manganese bisglycinate's role in supporting bone health and antioxidant protection. More studies are needed to confirm its cognitive benefits.
Preparation & Dosage
Traditional preparation
Typical dosage ranges from 1 mg to 5 mg per day. Consult a healthcare provider before use.
Nutritional Profile
- Provides manganese, an essential trace mineral for enzyme function. - Highly bioavailable form, ensuring effective absorption. - Contains glycine, which aids in reducing gastrointestinal side effects.
How It Works
Mechanism of Action
Manganese bisglycinate releases manganese ions that activate manganese superoxide dismutase (MnSOD) in mitochondria, neutralizing superoxide radicals. The mineral serves as a cofactor for glycosyltransferases in cartilage synthesis and pyruvate carboxylase in gluconeogenesis. The glycine chelation protects manganese from binding with fiber and phytates, improving intestinal absorption through amino acid transporters.
Clinical Evidence
Limited clinical trials exist specifically for manganese bisglycinate, though studies on manganese supplementation show modest benefits. A 12-week study of 334 postmenopausal women found 5mg daily manganese (with other minerals) improved bone mineral density by 1.5%. Absorption studies indicate chelated forms like bisglycinate achieve 3-5 times higher bioavailability than manganese sulfate. Most evidence comes from observational studies linking adequate manganese intake to reduced osteoporosis risk.
Safety & Interactions
Manganese bisglycinate is generally well-tolerated at doses under 10mg daily, with lower toxicity risk than inorganic forms. Excessive intake above 20mg daily may cause neurological symptoms including tremors and cognitive impairment. It may reduce absorption of iron and calcium when taken simultaneously, requiring separated dosing. Individuals with liver disease should avoid supplementation as manganese accumulates in liver tissue.

Frequently Asked Questions
What makes manganese bisglycinate better than other forms?
Manganese bisglycinate shows 3-5 times higher absorption than inorganic forms like manganese sulfate. The glycine chelation protects the mineral from binding with dietary inhibitors like fiber and allows absorption through amino acid transporters rather than competing with other minerals.
How much manganese bisglycinate should I take daily?
Most supplements contain 2-5mg of elemental manganese from bisglycinate, taken with meals. The upper limit is 11mg daily for adults, though chelated forms may be better tolerated at higher doses due to reduced gastrointestinal irritation.
Can manganese bisglycinate help with joint pain?
Manganese supports cartilage synthesis through glycosyltransferase activation, but evidence for joint pain relief is limited. One study found manganese with glucosamine reduced knee pain by 27% over 16 weeks, though the specific contribution of manganese wasn't isolated.
Does manganese bisglycinate interfere with other supplements?
Yes, manganese can reduce iron absorption by up to 40% and interfere with calcium uptake when taken together. Space manganese supplements 2-3 hours apart from iron, calcium, or magnesium for optimal absorption of all minerals.
Who should avoid manganese bisglycinate supplements?
People with liver disease, Parkinson's disease, or those taking antipsychotic medications should avoid manganese supplements. Welders and others with occupational manganese exposure should also avoid supplementation due to increased neurotoxicity risk from cumulative exposure.
What foods are naturally high in manganese?
Manganese is found in whole grains, legumes (beans and lentils), nuts, seeds, and leafy greens like spinach and kale. Tea and coffee are also notable sources of dietary manganese. However, the amount absorbed from food varies based on phytic acid content and individual digestive factors, which is why supplementation with manganese bisglycinate may be beneficial for those with specific deficiency risks.
Is manganese bisglycinate safe during pregnancy and breastfeeding?
While manganese is essential for fetal development and bone formation, pregnant and breastfeeding women should consult their healthcare provider before supplementing, as exceeding the recommended intake may pose risks. The tolerable upper intake level for manganese is 11 mg/day for adults, and supplementation should be individualized based on dietary intake and medical history. Always inform your doctor about any supplements you're considering during pregnancy or lactation.
Does manganese bisglycinate interact with common medications?
Manganese bisglycinate may interact with certain antibiotics (particularly fluoroquinolones and tetracyclines), as minerals can reduce their absorption if taken simultaneously. It may also affect the absorption of bisphosphonates used for bone health, so spacing doses 2+ hours apart is recommended. If you're taking prescription medications, discuss manganese supplementation with your healthcare provider to avoid potential absorption conflicts.
