Does Boron Raise Testosterone, and What Is in the Horsewood Boron Row?
Boron is the odd one out on the Horsewood panel. It is a mineral, not a plant, and the label leaves out the one number that would let you judge it. This page explains the trial, the doses and what is not published.
Nothing we cite shows that boron raises testosterone. The one controlled trial we cite, in male bodybuilders, credited the training and not the boron. Horsewood prints 20 mg of boron amino acid chelate per serving. The boron inside that chelate is only part of the 20 mg, and the label does not publish how much.
General information, not medical advice. Horsewood is a dietary supplement for healthy adults aged 18 and over. It is not a drug and it is not FDA approved. No dietary supplement is. It is not meant to diagnose, treat, cure or prevent any disease. A change in sexual function that is new, sudden or getting worse can have a medical cause, so see a doctor about it. Ask a doctor or pharmacist before use if you take medicine or have a health condition.
Does boron raise testosterone?
Searches for boron and testosterone are common, and the honest answer is short. The research we cite does not show that it does.
The best-known human study is a 1993 controlled trial in male bodybuilders. It measured plasma testosterone, lean mass and strength across seven weeks. Its conclusion was that the training, and not the boron, accounted for what changed. That is a negative result in exactly the group this kind of product targets.
There is also a general review of boron in nutrition, Nielsen 2014. It describes a small but real nutritional literature. Real does not mean large, and it does not mean the literature is about testosterone.
So we do not claim that the boron in Horsewood raises anything. We describe what is on the label, what the studies used, and what is missing.
What is a boron amino acid chelate?
A chelate is a mineral bound to a carrier. Here the carrier is an amino acid.
The point that matters for a reader is arithmetic. When a panel says 20 mg of boron amino acid chelate, it means 20 mg of the whole compound. The mineral itself is only a fraction of that weight, and the rest is the carrier.
Horsewood prints the whole-compound weight. That is not wrong. It just means the number you can see is not the number you would compare with a study.
How much boron is in Horsewood?
Here is the plain answer: not published. The panel lists the row as Boron Amino Acid Chelate, 20 mg per two-capsule serving. The elemental boron is not printed anywhere we can read it, and we do not print an estimate in its place.
A made-up figure sitting beside six numbers that were read off the label would be the one line on the page that you could not check. So the cell stays empty.
| Question | Answer |
|---|---|
| What does the panel print? | Boron Amino Acid Chelate, 20 mg per serving of two capsules |
| How much elemental boron is that? | Not published |
| How much do the studies we cite use? | 3 to 10 mg a day of elemental boron |
| Can the row be placed on that scale? | No, because the elemental figure is missing |
| Does this row sit in a blend that hides amounts? | No. The amount is printed, as it is for all seven rows |

How does 20 mg compare with the amounts that were studied?
The studies that make boron interesting to a men's formula dose it as elemental boron, in single-digit milligrams a day. We list 3 to 10 mg a day as the range in the work we cite.
Now look at the label. It says 20 mg, and the unit is a chelate. If the elemental part were small, the daily amount could sit below that range. If it were large, it could sit near or above it. The panel does not let you tell which.
That is the real cost of leaving out the number. It is not that the row is bad. It is that nobody reading the label can place it. A buyer who takes boron in a multivitamin or another product cannot add things up either.
- Horsewood prints Boron Amino Acid Chelate, 20 mg per serving of two capsules.
- Elemental boron inside that chelate is not published, and we do not estimate it.
- The studies we cite use 3 to 10 mg a day of elemental boron.
- A 1993 controlled trial in male bodybuilders credited the training, not the boron.
- Boron accumulates, so ask a pharmacist if you take it in any other product.
- Our sources say nothing about estrogen, so we make no claim about it.
Is boron a good fit for libido or erectile function?
People also search for boron and libido, boron and ED, and boron and hormone balance. We have no source that supports an answer to those, so we do not give one.
The seller's support lines talk about libido, desire and blood flow. They are the seller's words, shown on the benefits page and attributed to the seller. They are not trial results, and none of them traces to the boron row.
If a change in sexual function is new, sudden or getting worse, that is a medical question. A doctor can check causes such as blood pressure, blood sugar, thyroid and medicines. A mineral in a capsule is not a replacement for that conversation.
What about boron and estrogen?
This question comes up more than most. Several searches ask whether boron raises or lowers estrogen in men.
Our sources do not cover estrogen, so the answer on this page is: not published. We would rather leave it blank than quote a half-remembered claim. If it matters to you, perhaps because you are on a hormone treatment, ask your doctor, and take the bottle with you.
Is it safe to take boron with other supplements?
The safety point with boron is accumulation. The question to ask a pharmacist is whether you already take boron somewhere else, in a multivitamin, a bone formula or another product. Because the elemental figure here is not published, you cannot calculate your total.
At amounts far above the nutritional range, the reported effects are nausea and headache. We do not say that the Horsewood amount reaches them, because we do not know the elemental figure.
The bottle carries its own caution. It says not to exceed the recommended dose, and that pregnant or nursing mothers, children under 18 and anyone with a known medical condition should consult a physician. Horsewood is for adults aged 18 and over, and it is a dietary supplement, not a drug.
What would make the boron row easy to judge?
One extra line on the label would do it: the elemental boron per serving. Until then, you have three options.
- Ask the order desk on +1 (641) 711-1414 whether the elemental figure is available. If it is, we would like to hear it.
- Treat the row as unplaced, and judge the product on the other six rows and on your own routine.
- Use the 60-day guarantee as your safety net, and write your start date on the bottle.
Frequently asked questions
Does boron increase testosterone?
The research we cite does not show that it does. A 1993 controlled trial in male bodybuilders concluded the training, not the boron, accounted for the change.
How much boron is in Horsewood?
The panel prints 20 mg of boron amino acid chelate per serving. The elemental boron inside it is not published.
How much boron do studies use for testosterone research?
The studies we cite use 3 to 10 mg a day of elemental boron. The Horsewood row cannot be placed on that scale because its elemental figure is missing.
Does boron affect estrogen?
Our sources do not cover this, so we make no claim. Ask your doctor, especially if you are on a hormone treatment.
Can I take Horsewood with another boron supplement?
Ask a pharmacist first. Boron accumulates, and the elemental amount in Horsewood is not published, so you cannot add up your total.
Does boron improve libido?
We have no source that supports that, so we do not say it. The libido lines on the sales page are the seller's wording and not trial results.
Our view
Boron is a good example of how to read a label. The row has a number, and the number still does not answer the question you care about. The elemental figure is the one that matters, and it is missing.
We do not think that makes Horsewood a bad product. We think it makes the boron row unplaceable, and we say so rather than fill the gap with a guess. If you take other boron products, ask a pharmacist before you add this one.
Judge the capsule at week six against notes you wrote at the start, and remember that the 60-day guarantee runs from the day you buy.
