Quick summary

Boron glycinate is a chemical form of boron used in dietary supplements. Currently, there is insufficient evidence from human clinical studies or systematic reviews to confirm specific health benefits, recommended intakes, or safety profiles for boron glycinate. No authorized health claims exist from the European Food Safety Authority (EFSA) or other official bodies specifically for this compound. Data on its absorption, bioavailability, and presence in food sources are lacking, limiting comprehensive understanding at this time.

What is it?

Boron glycinate is a chelated form of the trace element boron, where boron is bound to the amino acid glycine. Chelation is often used in dietary supplements to potentially enhance mineral stability and absorption. Boron itself is a metalloid found naturally in the environment, and it is present in small quantities in various foods and drinking water. However, boron glycinate as a distinct supplement form has not been extensively studied or characterized in terms of nutritional requirements or health effects.

Main functions in the body

There are no direct studies describing the physiological roles or specific biological functions of boron glycinate. In general, boron is suggested to support bone health and influence mineral metabolism based on limited experimental data, but these roles have not been clinically confirmed for the glycinate form. The essentiality of boron for humans is not officially established, and its exact roles remain under investigation.

Recommended intake and upper limit

Official recommended dietary intakes or upper intake levels specific to boron glycinate are not established. Intake guidelines for elemental boron vary according to age, sex, and life stage, and official regulatory agencies such as the EFSA or the U.S. Institute of Medicine do not provide specific recommendations for boron glycinate. Consumers should be cautious, as excessive boron intake from any source may carry risks.

Best food sources

Data on the presence of boron glycinate in food is lacking. Boron in general can be found in small amounts in fruits, vegetables, nuts, and legumes, but it is predominantly present in inorganic or other organic forms rather than as boron glycinate.

Deficiency: causes, symptoms and risk groups

No specific deficiency symptoms or clinical syndromes have been documented for boron glycinate itself. Boron deficiency in humans is not well defined, and no established risk groups are recognized. Further research is needed to clarify if boron status, including its glycinate form, influences human health or nutrient balance.

Supplement forms

  • Boron glycinate

Boron glycinate is offered as a supplement form that combines boron with glycine. Other boron supplement forms (not detailed here) include boric acid, boron citrate, and boron aspartate, but no direct evidence compares their bioavailability or efficacy relative to boron glycinate at present.

Absorption and bioavailability

There is a lack of data regarding absorption, metabolic fate, and bioavailability of boron glycinate in humans. No known enhancers or inhibitors of its absorption have been identified from available literature, nor have differences between boron glycinate and other boron compounds been systematically studied.

Potential benefits: what does the evidence say?

Currently, no human clinical trials or systematic reviews have investigated the health effects of boron glycinate supplementation. Evidence for benefits is insufficient, and no conclusions can be drawn about its efficacy or potential therapeutic roles. This gap highlights the need for rigorous research before recommending boron glycinate for any health purpose.

Side effects and toxicity

Details on side effects or toxicity specific to boron glycinate are not available. In general, excessive boron intake from various sources may cause adverse effects, but safety thresholds for boron glycinate remain undefined. Consumers should avoid high doses unless under medical supervision.

Drug and nutrient interactions

No documented interactions between boron glycinate and medications or other nutrients have been identified. Due to the incomplete evidence base, potential interactions cannot be ruled out, particularly for individuals taking multiple supplements or prescription drugs.

Who should be careful?

People who are pregnant, breastfeeding, have kidney disease, thyroid disorders, iron overload conditions, or who take medications should consult a healthcare professional before using boron glycinate supplements. Given the lack of safety data, caution is warranted especially in vulnerable groups.

Frequently asked questions

  • Is boron glycinate essential for health? Boron itself is not officially classified as an essential nutrient for humans, and no specific roles for boron glycinate have been established.
  • Can boron glycinate prevent or treat diseases? No reliable human clinical evidence supports disease prevention or treatment claims for boron glycinate.
  • Are there risks associated with boron glycinate supplementation? Safety and toxicity data are not well defined, so high-dose supplementation is not recommended without medical advice.
  • How is boron glycinate different from other boron supplements? Boron glycinate is a chelated form bound to glycine, but differences in absorption or benefit compared to other boron forms have not been demonstrated.

Evidence limitations

  • No clinical trial or systematic review evidence identified for boron glycinate in humans.
  • No official recommended intake values or safety data specific to boron glycinate.
  • Lack of food source data and deficiency symptomatology for this compound.
