Quick summary
Molybdenum glycinate is a chelated form of molybdenum, an essential trace mineral necessary for human health. However, there is no specific published evidence on molybdenum glycinate regarding clinical supplementation, safety, absorption differences, or health benefits at this time.
What is it?
Molybdenum glycinate is a chemical compound combining the trace mineral molybdenum with the amino acid glycine, creating a chelated form designed for use in dietary supplements. Chelation typically aims to improve mineral stability or absorption, but for molybdenum glycinate, there is currently no direct scientific evidence demonstrating such effects compared to other molybdenum forms.
Main functions in the body
Molybdenum itself is an essential trace mineral involved as a cofactor in various enzymatic reactions critical for normal metabolism. Key enzymes that depend on molybdenum include:
- Sulfite oxidase: Involved in the metabolism of sulfur-containing amino acids.
- Xanthine oxidase: Plays a role in purine degradation and uric acid production.
- Aldehyde oxidase: Participates in the metabolism of aldehydes and nitrogen-containing compounds.
These enzymatic processes are fundamental for normal cellular function and detoxification pathways.
Recommended intake and upper limit
There are no specific Recommended Dietary Allowances (RDAs) or Adequate Intake (AI) values published for molybdenum glycinate as a supplement form. General molybdenum intake recommendations exist but are not detailed here because current information does not differentiate between molybdenum compounds.
Similarly, no upper intake levels (ULs) specific to molybdenum glycinate have been established. Safe intake levels for molybdenum overall vary by age, sex, and life stage.
Best food sources
No data are available on molybdenum intake from molybdenum glycinate in foods, as this form is primarily used in supplements. Common dietary sources of molybdenum (inorganic and organic forms) include legumes, grains, nuts, and leafy vegetables, but food content data specific to glycinate forms is lacking.
Deficiency: causes, symptoms and risk groups
There are no deficiency symptoms, specific causes, or at-risk groups reported or linked specifically to molybdenum glycinate. Molybdenum deficiency in humans is very rare and typically associated with genetic disorders affecting molybdenum enzymes or extremely low dietary intake of molybdenum itself.
Supplement forms
Molybdenum glycinate is one of several molybdenum supplement forms, characterized by chelation with glycine. No comparative data exist on the bioavailability, safety, or efficacy relative to other molybdenum forms such as molybdenum oxide or molybdenum sodium molybdate.
Absorption and bioavailability
There is no published human data available describing the absorption, bioavailability, or metabolic differences between molybdenum glycinate and other molybdenum supplement forms. Potential enhancers or inhibitors of absorption specific to this form remain unidentified.
Potential benefits: what does the evidence say?
No clinical trials or systematic review evidence specifically addressing the effects, benefits, or health outcomes of molybdenum glycinate supplementation have been identified. The broader role of molybdenum as a trace element is well-established in enzymatic functions, but specific claims related to molybdenum glycinate supplementation remain unsupported by direct evidence.
Side effects and toxicity
No data are available regarding common side effects or potential toxicity associated with molybdenum glycinate supplementation. Molybdenum as a mineral generally has a wide margin of safety at nutritional levels, but high-dose supplementation should be approached with caution. As such, molybdenum glycinate safety and tolerability profiles require further verification.
Drug and nutrient interactions
No drug-nutrient or nutrient-nutrient interactions have been reported specifically for molybdenum glycinate. In general, molybdenum may theoretically interact with certain medications, but such interactions are not documented with this chelated form.
Who should be careful?
Due to the absence of safety and dosage information, people who are pregnant or breastfeeding, have medical conditions (particularly kidney or thyroid disease), or have disorders related to mineral metabolism or iron overload should consult a healthcare professional before using molybdenum glycinate supplements. Those using medications should also seek personalized advice to avoid potential interactions.
Frequently asked questions
- Is molybdenum glycinate better absorbed than other forms of molybdenum?
Currently, there is no scientific evidence comparing the absorption or effectiveness of molybdenum glycinate against other molybdenum compounds. - What is the role of molybdenum in the body?
Molybdenum is a trace mineral that acts as a cofactor for enzymes needed in important metabolic pathways such as sulfur amino acid metabolism and purine degradation. - Can molybdenum glycinate prevent deficiency?
Since molybdenum deficiency is rare and specific data on glycinate forms are lacking, no claims can be made about its preventative effectiveness versus other molybdenum sources. - Are there any known safety concerns with molybdenum glycinate?
No specific safety concerns or toxicity data have been published on this form. Caution is advised until more evidence is available.
Evidence limitations
- No identified published human clinical trials, systematic reviews, or official regulatory documents specifically describe molybdenum glycinate.
- There is a lack of safety, toxicity, dosage, or drug interaction data for molybdenum glycinate.
- Data are absent regarding bioavailability differences or possible superiority of this form compared to other molybdenum compounds.
