Ingredient profile
Boron in Vapofil: 20 mg of Chelate, About 1 mg of Boron
Vapofil lists 20 mg of boron amino acid chelate 5% per 2-capsule serving. Only 5% of that weight is boron, so you get about 1 mg. Most adults already eat 0.87 to 1.35 mg a day, and the adult upper limit is 20 mg. The study often cited for men gave 10 mg a day to 8 men for one week.

The mineral
What is boron amino acid chelate?
Boron is a trace mineral that most people get from food. In a chelate, the boron is bound to an amino acid. The "5%" on the Vapofil label tells you how much of the compound's weight is boron itself.
The nut in the header photo is a brand stock image. The boron in Vapofil is a lab-made chelate, not a nut extract. Boron has no Daily Value, which is why the label marks it with a dagger (21 CFR 101.36, Supplement labels).
| Label name | Boron Amino Acid Chelate 5% |
|---|---|
| What it is | Boron bound to an amino acid; 5% of the weight is boron |
| Type | Trace mineral |
| Position on the label | Line 5 of 7 |
| Amount per serving | 20 mg of chelate = about 1 mg of boron per serving (our math: 5% of 20 mg) |
| What research shows | One small study gave 8 men 10 mg of boron a day for a week; the adult upper limit is 20 mg a day |
| Strength of evidence | One tiny short study |
| Why it is in the formula (brand view) | Marketed with hormone claims we cover on one page |
| Main caution | About 1 mg is close to what food already supplies (about 0.9-1.4 mg a day), far below the 20 mg upper limit. |
The math
How much boron is in Vapofil?
About 1 mg. The label weighs the whole chelate, so a little arithmetic is needed.
Two capsules hold 20 mg of boron amino acid chelate. Five percent of 20 mg is 1 mg. That is our math, since the label does not print the boron figure. The table compares 1 mg with other numbers from the NIH Office of Dietary Supplements (NIH ODS, Boron) and the small study (Boron study, 8 men).
| Source | Boron per day | Note |
|---|---|---|
| Vapofil, 2 capsules | About 1 mg | 5% of 20 mg of chelate |
| Typical US diet | 0.87 to 1.35 mg | Median intakes from food |
| Common supplements | 0.15 to 6 mg | Elemental boron |
| The 8-man study | 10 mg | One week only |
| Adult upper limit | 20 mg | Highest daily intake considered safe |
Dose check
How does Vapofil's boron compare with the study dose?
About one tenth. The bars show boron and five other ingredients against research figures.
Put simply, Vapofil adds roughly one more day's worth of food boron. The full comparison for every ingredient is in the Vapofil dose guide.
The research
What did the boron and testosterone study find?
It found short-term hormone changes in a very small group. Eight male volunteers took a 10 mg boron capsule each day, with blood tests on day 0, day 1 and day 7. After one week, free testosterone rose and estradiol fell. The abstract also reports that three inflammatory markers dropped (Boron study, 8 men).
Why it proves little
- Eight men is a tiny sample.
- One week says nothing about longer use.
- The dose was about ten times what Vapofil supplies.
- We could read only the abstract, which describes no placebo group.
The sales page makes hormone claims for boron that we do not repeat. Each is checked on the sales claims page, and the study gets a fuller look in our post on boron and testosterone.
Context
What actually matters if you worry about low testosterone?
A blood test, then habits. Sleep and movement have better support than any mineral capsule.
Low testosterone is diagnosed, not guessed. The AUA uses a total level below 300 ng/dL plus symptoms, confirmed by two early-morning tests (AUA, Testosterone deficiency guideline). Mayo Clinic notes that levels drop about 1% a year after 30 or 40. It says treating normal aging with hormones is not advisable (Mayo Clinic, Testosterone and aging).
- Morning, 2 capsules
With an 8 oz glass of water. Morning comes from the sales page; the label sets no time.
- Move most days
CDC advises 150 minutes of moderate activity a week plus 2 days of strength work.
- Sleep 7 hours or more
In a small lab study, a week of 5-hour nights lowered young men's testosterone by 10-15%.
Activity advice (CDC, Physical activity for adults); sleep (CDC, Sleep) (UChicago Medicine, Sleep and testosterone); directions (Vapofil sales page, Prices and guarantee).
Lifestyle is the first step the AUA names for men with low levels (AUA, Testosterone deficiency guideline). In a small lab study, a week of five-hour nights lowered young men's testosterone by 10 to 15 percent (UChicago Medicine, Sleep and testosterone).
Safety
Is the boron in Vapofil safe?
At about 1 mg a day, it sits far below the 20 mg upper limit for adults. NIH also says boron is not known to have any clinically relevant interactions with medicines (NIH ODS, Boron). Still, do not take more than the label's two capsules. Other ingredients carry their own cautions.
Low energy, low sex drive or erection problems have many causes. They include sleep apnea, thyroid problems, diabetes, medicines and heart disease (Mayo Clinic, Testosterone and aging) (NIDDK, ED causes). ED can be an early sign of heart disease, so get checked rather than reaching for a mineral.
Fair verdict
Is the boron in Vapofil worth taking?
In its favor
- The chelate and its 5% strength are printed, so the math is possible.
- Far below the upper limit, with no known drug interactions.
Against it
- About 1 mg, close to what food already supplies.
- The cited study was 8 men for one week at 10 mg.

FAQ
Boron questions
How many milligrams of boron are in two Vapofil capsules?
About 1 mg per 2-capsule serving. Its label shows 20 mg of the 5% chelate, and one twentieth of 20 mg is 1 mg. That is our math from the label; the elemental amount is not printed on the bottle.
Can boron supplements change testosterone?
One small study reported a rise in free testosterone after 8 men took 10 mg of boron daily for a week. That is too small and too short to show a lasting effect. Vapofil supplies about one tenth of that dose.
What is the safe upper limit for boron?
The NIH Office of Dietary Supplements sets the adult upper limit at 20 mg of boron a day. Vapofil provides about 1 mg, so it stays far below that line. Most adults already get roughly 0.9 to 1.4 mg a day from food.
Why does Vapofil include boron?
The label does not say. The sales page ties boron to hormone and other claims that we do not repeat. The research behind it is thin: one study of 8 men for one week at 10 mg a day, about ten times Vapofil's dose.
What does chelate 5% mean on a supplement label?
It means boron makes up 5% of the compound's weight; the rest is the amino acid it is bound to. So the 20 mg on the Vapofil label is the weight of the whole chelate, which carries about 1 mg of boron.
Is boron safe to take with prescription drugs?
NIH says boron is not known to have any clinically relevant interactions with medicines. Other Vapofil ingredients do carry cautions, such as saw palmetto with blood thinners. Bring the full label to your doctor or pharmacist.
Is 1 mg of boron a day enough to matter?
Probably not on its own. About 1 mg is close to what a day of food supplies, and the study most often cited used 10 mg. No trial has tested 1 mg of boron for men's sexual health or for Vapofil itself.
