Bororganic Boron
Also known as: Boron, boron citrate, boric acid, sodium borate, Bororganic Boron
Overview
Boron is a naturally occurring trace element found in soil, water, and various foods like fruits, vegetables, nuts, and legumes. As a supplement, it is typically provided in organic forms such as boron citrate, often referred to as "Bororganic Boron," to enhance absorption. Boron plays a role in mineral metabolism, particularly involving calcium, magnesium, and phosphorus, and is thought to influence steroid hormone metabolism. Supplementation is primarily investigated for its potential benefits in bone health, modulation of sex hormones (like testosterone and estradiol), and anti-inflammatory effects. While research is ongoing, the current evidence base consists mainly of small, short-term human studies, and robust clinical recommendations are not yet established. It is considered a trace mineral supplement.
Benefits
Boron supplementation has shown some potential, though the evidence is not yet robust. One small study (n=8) indicated that 6 mg/day of boron for one week led to a 28% increase in free testosterone and a 39% decrease in estradiol in healthy males. This study also reported significant decreases in inflammatory markers (IL-6, hs-CRP, TNF-α), but the clinical significance of these changes is unclear due to the study's small size and short duration. Boron may also support bone health by influencing the metabolism of calcium, magnesium, and vitamin D, which are crucial for bone density, but large-scale human trials with clinical fracture outcomes are lacking. Anecdotal reports and observational data suggest possible benefits for cognitive function and hormone balance in postmenopausal women, but these claims require more rigorous scientific validation through randomized controlled trials. There is no consistent evidence to support benefits for athletic performance enhancement or kidney stone prevention.
How it works
Boron influences the metabolism and utilization of essential minerals such as calcium, magnesium, and vitamin D, which are critical for maintaining bone health. It is also believed to modulate steroid hormone metabolism, potentially by increasing the conversion of total testosterone to its more active 'free' form and reducing levels of estradiol. This interaction primarily affects the endocrine system (sex hormones) and the skeletal system (bone metabolism). Boron may also interact with the immune system by influencing inflammatory markers. The exact molecular targets and specific mechanisms by which boron exerts these effects are not yet fully understood, but it is thought to act as a cofactor or modulator in various enzymatic processes involving these minerals and hormones. Absorption of boron from dietary sources and supplements is generally efficient, but specific bioavailability differences between various supplemental forms are not well-studied.
Side effects
Boron is generally considered likely safe when consumed at doses up to 20 mg per day. However, higher doses can lead to toxicity, which may manifest as symptoms such as irritability, tremors, and gastrointestinal distress. Chronic high intake of boron has also been linked to potential male fertility issues. Common side effects are not well-documented in clinical studies, as most adverse event reports stem from cases of overdose rather than typical supplementation. Rare side effects include acute toxicity, which can occur with very high, excessive intake. There are no well-documented drug interactions, but theoretical interactions with hormone therapies and other mineral supplements are possible. Boron supplementation is contraindicated during pregnancy and lactation due to a lack of safety data, and caution is advised for individuals with renal impairment. Safety in special populations such as children, the elderly, or those with chronic diseases has not been established.
Dosage
The minimum effective dose for boron is not clearly established, but some hormonal effects have been observed at daily doses of 3–6 mg. The optimal dosage range commonly used in studies is between 3–10 mg per day. Doses higher than this range lack evidence for additional benefits and may increase the risk of adverse effects. The maximum safe dose is considered to be 20 mg per day; exceeding this limit may lead to toxicity. There are no specific timing considerations, with daily dosing being the typical recommendation. Boron citrate and other organic salts are frequently used in supplements, but comparative data on the bioavailability of different forms are limited. Dietary boron is generally well absorbed. While no specific cofactors are required, adequate intake of calcium, magnesium, and vitamin D may optimize any bone-related benefits.
FAQs
Is boron supplementation safe?
Boron is likely safe at doses up to 20 mg per day. Higher doses can lead to toxicity, so it's important not to exceed recommended amounts without medical supervision.
When should I take boron?
There are no specific timing recommendations for boron; daily oral administration is typical. It can be taken at any time of day, with or without food.
What results can I expect from boron supplementation?
Modest, short-term changes in hormone levels (like increased free testosterone, decreased estradiol) and inflammatory markers are possible. However, significant clinical benefits for bone density, muscle mass, or athletic performance are not well-supported by current evidence.
Is boron a performance enhancer?
No, boron is not a proven performance enhancer. Claims of dramatic benefits for athletic performance or as a substitute for hormone therapy are not evidence-based.

The study aims to assess cardiometabolic and inflammatory markers, and its results are pending, which could provide higher-quality evidence on boron's effects.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC4712861/ – This article discusses a small randomized controlled trial (n=8 healthy males) that administered 6 mg/day of boron for one week. The study reported a 28% increase in free testosterone, a 39% decrease in estradiol, and significant reductions in inflammatory markers (IL-6, hs-CRP, TNF-α). However, the study's very small sample size and short duration limit the generalizability and clinical relevance of these findings.
