HelloPharmacist Scorecard of Boron 3 mg by Nature's Harmony

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: boron, at 3 mg per capsule. Boron is a mineral that plays a role in bone health and may support other body functions.

The inactive ingredients are microcrystalline cellulose, magnesium stearate, silicon dioxide, and gelatin — these are standard capsule fillers and binders with no active role.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Boron's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: maintaining healthy bones.
  • We looked for evidence on: Osteoporosis, Osteoarthritis, Bone density, Bone strength.
  • The closest evidence on file: Boron is rated "Insufficient Reliable Evidence To Rate" for Osteoporosis (Natural Medicines).
  • Also on file: Boron is rated "Insufficient Reliable Evidence To Rate" for Osteoarthritis.

Boron is likely effective for treating boron deficiency. For vaginal yeast infections (vaginal candidiasis) and radiation-related skin irritation (radiation dermatitis), the evidence rates it as possibly effective — meaning some promise, but more research is needed.

For athletic performance, it's rated possibly ineffective, so don't expect a boost there.

The evidence, ingredient by ingredient Boron

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

At doses below 20 mg daily, boron is generally well tolerated orally. The most common side effects are loss of appetite, skin rash, redness, and indigestion.

At much higher doses — 1 gram daily of boric acid or 25 grams daily of boric tartrate — chronic use can cause hair loss and worsening skin problems. Doses in the range of 15–20 grams or more can cause serious poisoning with nausea, vomiting, diarrhea, and stomach pain.

Avoid this supplement during pregnancy and while breastfeeding. High amounts of boron may harm the fetus, and there isn't enough safety data for nursing.

Why this rating?

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.

This 3 mg dose is well below the toxic threshold and is appropriate if you have a boron deficiency or want to explore its possible role in vaginal yeast infections or radiation skin injury. If you're pregnant, nursing, or have concerns about whether it fits your health picture, talk it over with your doctor or pharmacist before starting.

Boron 3 mg by Nature's Harmony: Common Questions

Does Boron 3 mg by Nature's Harmony interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Boron 3 mg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Boron 3 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is boron safe during pregnancy?
No — the safety data advises against boron supplements in pregnancy because high amounts may be harmful to the fetus. If you're pregnant or planning to become pregnant, talk with your doctor or pharmacist before taking this.
Can I take boron while breastfeeding?
The data advises against it due to limited safety information. There isn't enough evidence to say it's safe while nursing, so check with your doctor or pharmacist for personalized guidance.
What is boron actually used for?
Boron is likely effective for boron deficiency. It's possibly effective for vaginal yeast infections and radiation-related skin damage, though the evidence is still developing. It's not shown to help athletic performance.
What side effects should I watch for at this dose?
At 3 mg daily, boron is well tolerated. The most common side effects are loss of appetite, skin rash or redness, and indigestion — and they're uncommon at this low dose. Serious effects only occur at much higher doses.
Is this product safe to take long-term?
Yes, at 3 mg daily. That's well below the safe upper limit of 20 mg. Chronic problems like hair loss and severe skin damage happen only with doses around 1 gram or higher — far above what's in this supplement.
