Best 10 Boron Supplements in 2025

Boron is known as a trace mineral that is believed to support strong bones, balance hormones, and even help your body use other minerals like calcium and magnesium. It may also improve your brain function and reduce inflammation. As it’s hard to get an adequate amount of boron from food alone, many people choose to take it as a supplement.

You’ll find many boron supplements on the market, and each one might offer something different. Some have single formulas containing only boron, while others might include added nutrients for extra support. There are also various forms and doses to consider. Choosing the right supplement may depend on your goals, whether it’s stronger bones, better focus, or hormone support.

In this guide, you’ll learn about the 10 best boron supplements available today, along with their pros and cons. We will also help you learn about the potential drawbacks of these supplements and evaluate them based on their pricing and brand reputation.

What Is A Boron Supplement?

A boron supplement contains a specific dose of boron, usually in forms like boron citrate, boron glycinate, or boron aspartate. These forms are used because they are stable and easy for the body to absorb. Boron supplements are taken to support specific functions in the body, such as better bone health and joint support. Some studies show that 3 mg of boron daily might help improve bone strength and support testosterone or estrogen levels. These supplements are usually available in capsules, tablets, or liquid drops and are taken once per day.

Side Effects of Boron Supplements

1. May Cause Diarrhea

   Diarrhea often occurs when boron intake exceeds recommended levels. High doses of Boron Supplements could irritate your digestive tract lining, disrupting fluid and electrolyte balance, which increases bowel motility and causes loose stools. Studies show this typically happens at doses well above the adult tolerable upper intake level (UL) of about 20 mg per day. Taking boron supplements on an empty stomach or at very high concentrations increases the risk, while typical doses of 3 to 6 mg daily rarely cause digestive issues in healthy adults.

2. Could Trigger Rashes

   Boron supplements can trigger skin reactions such as rashes. This occurs because boron, as a trace mineral, interacts with the body’s immune system and skin cells. In some people, especially those sensitive to boron or other supplement ingredients, this interaction can provoke an allergic or irritant response. The rash may present as redness, itching, or small bumps on the skin, typically localized but sometimes spreading over larger areas. Such skin reactions often result from boron’s ability to influence inflammatory pathways or by causing mild toxicity if dosed beyond safe levels. Some boron supplements contain fillers or additives that could also contribute to skin irritation.

3. May Induce Weakness

   Weakness linked to boron supplementation generally stems from your body’s reaction to excessive boron intake, which may disrupt normal metabolic and neurological functions. High levels of boron might interfere with the balance of essential minerals like magnesium and calcium, crucial for muscle contraction and nerve signaling. This imbalance might result in muscle fatigue or a general feeling of weakness. Boron toxicity can affect cellular energy production and can trigger irritability, weakness, and tremors. Weakness may also be a sign that the body is under stress from processing excess boron, potentially affecting your nervous system and leading to symptoms like lethargy or reduced physical stamina.

How Did We Evaluate The Best Boron Supplements?

1. Brand Reputation

   When evaluating boron supplements, we looked for third-party ratings and consumer feedback that play a critical role in learning about a brand’s trust, service quality, and transparency standards.

   Swanson ranks highest in overall brand reputation for boron supplements, with a 4.3-star rating on Trustpilot and an A+ rating from the Better Business Bureau (BBB), signaling strong customer satisfaction and reliable service.

   Now Foods also holds an A+ rating from the BBB and is widely respected for its transparency and product consistency, though it doesn’t have a Trustpilot presence.

   Nutricost holds a B+ rating from the Better Business Bureau (BBB). It’s relatively new to BBB accreditation since April 2023, and some customer service inconsistencies have been reported, indicating room for improvement in responsiveness.

   Botanic Choice, backed by over a century of history and an A+ BBB rating, also stands out for maintaining a clean service record, though it lacks broader user feedback online.

   Pure Encapsulations has an A- rating from the BBB, with some complaints on record, indicating generally reliable customer support, though with some reported issues. Horbäach also received an A- from BBB and, while it has no Trustpilot presence, maintains moderate trust through consistent retail performance. Both brands are well-established but limited in direct consumer review data, which slightly lowers their transparency.

   Metagenics falls short in overall reputation, with a low 2.2 Trustpilot from 10 reviews, a B rating from BBB, and complaints suggesting recurring customer service problems despite the use of its products.

   Pure TheraPro, Vibrant Health, and BlueBonnet Super lack visibility on both BBB and Trustpilot, offering minimal third-party validation. This absence of external feedback makes it difficult to measure how these brands manage quality or customer issues.

2. Value for money

   We evaluated boron supplements as on the cost per capsule and dosage, which helps us understand which brand can provide the best value for money.

   Horbäach Triple Action Boron Complex costs $17.03 for 300 capsules and offers the best value with a high 6 mg dose at just $0.06 per capsule.

   Swanson Triple Boron Complex, priced at $11.99 for 250 capsules, is the most affordable overall, with each 3 mg capsule costing only $0.05, suitable for long-term use.

   Nutricost Boron, at $16.97 for 240 capsules, provides 3 mg per serving at around $0.07 per capsule, offering a good balance of quantity and cost.

   Now Foods Boron costs $8.99 for 100 capsules and delivers a basic 3 mg dose at $0.09 per capsule, while Botanic Choice Super Boron Complex, priced at $9.00 for 90 capsules, offers 3 mg at $0.10 per capsule.

   Pure TheraPro Bio Boron is priced at $19.47 for 180 capsules and offers a higher 5 mg dose at about $0.11 per capsule, making it a fair option for people needing more boron per serving.

   Pure Encapsulations Boron costs $13.40 for 60 capsules and contains only 2 mg per serving, working out to $0.22 per capsule. The brand is known for clean formulations, but the low dose limits its value.

   BlueBonnet Super Boron Bone Formula, at $26.50 for 120 capsules, also comes out to $0.22 per capsule and may be better suited for those looking for a more comprehensive bone-support formula.

   Metagenics Bone Builder with Boron is priced at $65.00 for 270 capsules, costing $0.24 per capsule, and includes other bone-support nutrients, worth considering only if you need a broader supplement.

   Vibrant Health Boron, at $17.50 for 60 capsules, ends up being the least cost-effective option at $0.29 per capsule, with no standout features to justify the higher price.

Conclusion

Boron supplements could support skeletal integrity and the absorption and regulation of nutrients like calcium, magnesium, and vitamin D. The supplements reviewed in this article claim to fill that nutritional gap by offering bioavailable forms of boron in measured doses.

Despite their potential, boron supplements also come with some limitations. Much of the supporting research is preliminary, and boron is not universally classified as an essential nutrient. Excess boron intake may lead to side effects such as skin irritation, gastrointestinal discomfort, or weakness. These outcomes often result from personal sensitivity or long-term overuse. It’s important to assess your health needs, dietary intake, and existing conditions before trying boron supplements. Choosing products with clear labeling and evidence-based dosing is essential, but professional guidance is equally important. Consult your doctor before starting boron supplementation, especially for long-term use, to ensure safety and alignment with your health strategy.
