Boron and Testosterone: Cheap and Unpopular Trace Mineral and T-Booster

There are multiple micronutrients (vitamins and minerals) that contribute to testosterone synthesis, such as: vitamins A, C, D, K2, zinc, magnesium, iodine, calcium, etc…

…But what is often left unmentioned is the trace mineral boron. When in fact it’s the boron that currently holds the most impressive results on natural T production in terms of scientific evidence.

Many experts believe that we’re getting significantly less boron through the diet than our ancestors did, and this is because the modern day “power farming” quickly depletes the soil in which our food is grown, leaving less boron – and less of multiple other naturally occurring micronutrients – into the end product.

But is boron something you’d want to miss from the diet? Definitely not according to the research which shows the benefits of boron:

Boron and Testosterone Levels

Boron testosterone supplementation to increase testosteroneBoron is a rare mineral in Earth, and in this whole universe. And this is because boron is a “trace leftover” of the big bang, arriving Earth via cosmic dust and meteor materials…

…Hence why only about 0.001% of the Earths crust is boron.

Not only is boron rare in the Earth, it’s also somewhat uncommon as a supplemental micronutrient. It isn’t even included in the list of “essential vitamins and minerals for human survival”, and there isn’t a set minimum requirement for dietary boron (although it has a RDI of ~3 mg/day).

However – as unnecessary as boron may seem like – what most of the guys don’t know is that boron can be easily labeled as a natural testosterone booster. This one ridiculously cheap and unpopular trace mineral is actually much more effective in raising ones natural T production than most of the “T-Booster” products flying of the shelves at your local GNC are

Take this study from Naghii et al. as an example. The researchers in this trial gave eight of their male subjects ~10 mg’s of boron supplement, every morning for 7 consecutive days. After the week had passed, the scientists compared their subjects blood results from day 1 to day 7, and found out that:

  • free testosterone levels had increased by 28%
  • free estrogen levels had decreased by -39%
  • dihydrotestosterone (DHT) levels rose by 10%
  • many inflammation biomarkers (hsCRP, TNF-α) dropped significantly

NOTE: The same researchers measured testosterone levels on their subjects in a study conducted in 1997 set to examine boron’s effects on cardiovascular risk, in that trial 10 mg’s of daily boron increased total testosterone levels by 15%, slight increases were also seen in total estrogen levels, which should be noted.

Another study from Mjilkovich et al. looked how boron supplementation impacts serum vitamin D levels, but on the side they also measured free testosterone levels. After 2 months of giving their 13 subject males 6 mg’s of daily boron (calcium fructo-borate) the levels of free testosterone had increased by 29,5% on average, a number similar to the findings of Naghii et al.

Two rodent studies (study, study) examining boron’s toxicity have also found significant dose-dependent increases in testosterone levels after boron supplementation, highest dose (500 mg/day) leading to a massive 160% increase. Though this amount – not only crazily expensive – would be highly toxic also, since dosages exceeding 25 mg/day start showing symptoms of toxicity and are not recommended.

Possibly the best and cleanest boron glycinate can be found from Pure Encapsulations (affiliate link).

Conclusion on Boron Testosterone Supplementation

There’s good amount of scientific evidence speaking for the health benefits of boron. It has the ability to increase testosterone levels in healthy human males, and in rodents, and also in women (with boron deficiency). That is why I recommend you take a boron testosterone supplement.

A dose range that should be able to increase testosterone levels (without becoming toxic) falls in between 3-25 mg/day.

Aside from supplementation (the brand above is highly recommended for it’s incredibly high quality standards), some good dietary boron sources include: raisins, gelatin, prunes, dates, avocados, almonds, Brazil nuts, and honey.

    I think another reason boron won’t be a famous supplement is because producers/companies who do sell boron for the purpose of increasing testosterone (for example, to bodybuilders) will hype it up as some steroid alternative. Gullible idiots then go out and buy it, expect to blow up in size like Jay Cutler, get mad that they don’t, then trash boron, saying it’s shit.

    • Ali Kuoppala on 01/08/2014 at 21:05

      Yes, those are my thoughts exactly.

      That’s why testosterone boosters in general have so bad rep too.

      • CKirkman on 07/07/2015 at 20:01

        Interesting concepts, however using myself as a case example, being female and having been on 75mg a day for a little over one year now. Instead of increasing my estrogen, I got more of a balancing effect, and I was actually just taking for joint/bone benefits, didn’t realize it would address my life long estrogen dominance at the same time. I was doing some research to back up a video I recently saw on YouTube of Dr Flechas discussing Boron and talking about the low arthritis rates in countries where Boron intake was higher.

        • Maryjane William on 05/05/2017 at 20:24

          What is your source for boron? Most of the boron products available are 3mg per capsule. Does there exist a high dosage version?

          • CKirkman on 05/05/2017 at 23:16

            Yes Hakala Labs makes a 30mg and a 75mg Boron supplement that they call BoroTabs. The 30mg is available on their website, you have to call or email them about 75mg as that is usually only available through a practitioner. I also have used Borax in the past when I ran out of BoroTabs. I know someone here was trying to say it was toxic in the borax form, but I have used it in the borax form for up to 3 months at a time. I believe my calculation was about 1/8 tsp yields around 30mg boron.

          • Maryjane William on 06/05/2017 at 01:10

            Thank you so much for that info. Much appreciated.

  2. Hotsauce on 09/07/2014 at 17:20

    Hi if you’re into minerals, check out Indium you’ll be quite amazed.

  3. Ali Kuoppala on 01/08/2014 at 21:04

    Yeah, I recently got Solgar’s Boron in pill form too, so I’m currently using both at 20-30 mg dose.

    I’m always going over the daily recommendations, I don’t really know why, it’s a habit that has stuck with me as I believe that the governmental recommendations are usually too low on everything.

  4. Mike Gibson on 03/09/2014 at 08:29

    I just read on another website that boron could potentially increase estrogen, at least in women. (the site in question was just a general health-related site, not related to T. I was looking to see if there was a boron USRDA.) do you know what the story is there, and how/why it might be different for men? – thanks

  5. Bo Jangles on 27/01/2015 at 06:58

    I’ve been amazed by the effects of boron on myself. Most developed countries have a low intake.

    • GRoy on 06/02/2016 at 18:59

      Jim, how do you take 20 mule team borax? Mix it in water or?

      Can you tell us the effects you’ve seen?


      • jbat001 on 12/02/2016 at 14:34

        DO NOT EAT BORAX! It’s not the same thing as eating boron citrate or other edible forms of boron. If you eat borax, you will get boric acid poisoning, and you will never forget the experience!

        • Jac on 02/02/2017 at 15:28

          I haven’t got anything from taking borax.. I presume you must have, to be able to truthfully tell us what happens? Probably took too much. Borax is NOT boric acid, either.

          • John True on 22/03/2017 at 10:30

            Borax IS a salt derived from Boric Acid. Borax and boric acid both are toxic to humans.
            Acute oral ingestion of 2 to 20 grams or more can result
            in symptoms that include nausea, vomiting, abdominal pain, diarrhea,
            depression of the central nervous sytem, and convulsions. Subacute or
            chronic doses may result in signs and symptoms including
            dermatitis, loss of appetite, nausea, and vomiting. In the occupational
            setting, exposures to airborne borax dusts have been
            shown to be irritating to the respiratory tract and the eyes of workers.
            These symptoms for both acute and chronic exposures, include eye
            irritation; dryness of mouth, nose, or throat; sore throat; and
            productive cough.

          • Jac on 22/03/2017 at 10:44

            Depends on which research paper you read. Proof is in the pudding, as it were. I’m still taking it at the correct dosage (it’s very low at around the equivalent of 3mg a day – the dosage that boron tablets are sold at in supplement shops and perfectly legal). I’m still alive and don’t experience any of those symptoms you quoted. Plus, at 65, my sex drive is perfectly good – I am a woman, by the way, so not looking to increase testosterone.

        • Yohn on 14/02/2017 at 19:55

          Your Wrong

  6. bahadur on 12/04/2015 at 19:26

    Study says boron also increased cortisol..

    • The real lebanese on 01/11/2015 at 21:46

      Regardless, it still increased testosterone.

      The rise in cortisol was not enough to reduce T levels.

  7. Jack O'Neill on 20/06/2015 at 11:34

    Boton increases estrogen though. We don’t want that, do we? I hope you’ll give an answer.

    • Ali Kuoppala on 20/06/2015 at 13:39

      Apparently increases E in women -

      But lowers E on men -

      I suspect this is because of gender differences and higher aromatase in women.

      • Manos Vr on 13/04/2017 at 16:08

        in the 1997 study it increased Estradiol in 18 male subjects by almost 50% (51.9 to 73.9 pmol/L). This is a threefold and then some percentage increase compared to what it did for testosterone.This suggests males should be very careful with Boron supplementation since such an increase in estrogen can cause sexual dysfunction, destroy libido and all around be contradicting the mechanisms of the male body

    • Yohn on 14/02/2017 at 19:56

      Estrogen helps build bones

  8. Eli Zìháo on 07/11/2015 at 19:55

    You could just eat a 100-gram serving of raisins (4.5 mg boron)

  9. Musa Obaid on 11/11/2015 at 01:30

    I started using Boron for a few days, and I was taking about 10mgs a day and after a few days I started getting hot flashes? I am very active and pretty sure my testosterone is very high, as I grow muscle very fast and have a very deep voice, wide jaw bone and very high sex drive, but as soon as i started supplementing with boron I started to see different effects than expected which were very confusing, as I looked these effects up online it stated that these were effects were due to drastic changes in testosterone levels, like andropause in men where testosterone drops significantly. Any thoughts? I stopped taking the supplement and it wasnt a capsule but it was liquid boron. Also might I add i am only 20

  10. Ezequiel on 28/11/2015 at 13:42

    Borax can be used as a source of boron?

    • jbat001 on 12/02/2016 at 14:02

      You can’t eat borax! You need something like Boron Citrate instead, lol….

      • Ezequiel on 12/02/2016 at 14:14

        why not?

        • jbat001 on 12/02/2016 at 16:29

          Borax is the salt form of boric acid. If you eat it, you will get boric acid poisoning.

          Symptoms of poisoning can include blue-green vomit, diarrhea and a red rash on the skin. Other possible symptoms include blisters, collapse, convulsions, coma fever, sloughing of skin and fever.

          Boron needs to be chelated with something else to make it safe to ingest, like boron citrate or boron aspartate. Don’t eat borax – it’ll mess you up!

    How long should one take boron before coming off of it?

  13. Yohn on 14/02/2017 at 19:58

    you most certainly can consume Borax! Add 1/8 teaspoon per 1 & 1/2 liters of good water. Drink a little each day.

    • Gabriel Henrique De Azevêdo Ve on 22/05/2017 at 15:29

      I’ll do mine around here. But have you done any tests? Thank you.

  14. Manos Vr on 13/04/2017 at 16:10

    Heads up:in the 1997 study 10 mg/d of Boron for 4 weeks increased Estradiol in 18 male subjects by almost 50% (51.9 to 73.9 pmol/L). This is a threefold and then some percentage increase compared to what it did for testosterone.This suggests males should be very careful with Boron supplementation since such an increase in estrogen can cause sexual dysfunction, destroy libido and all around be contradicting the mechanisms of the male body

  15. Manos Vr on 13/04/2017 at 16:11

    Hopefully someone see’s my comment before Ali deletes it as Boron is one of the main ingredients included it Testro-x lol

    • Ali Kuoppala on 13/04/2017 at 16:54

      Lol why would I delete your comment. I have seen this study before and discussed it on the forum. The researchers write that the increased estrogen is likely due to testosterone increasing and some of it converting to estrogen. Still, the 2 other studies showed reduced estrogen levels.

      You could eat some white button mushrooms and take vitamin E to drive aromatase down anyway. Of course, the increased E can be because of some other factor, the researchers only speculate it to be because of higher testosterone.

      • Manos Vr on 24/04/2017 at 14:01

        The increase in E seen on the study is 50%. So how could this be a product of higher testosterone since in the same study Boron supplementation increased T by 15% only. It doesnt add up. I would stay away from it until further research examines why this happens and how similar results with the E lowering studies can be replicated without risk of destroying your libido

        • Ali Kuoppala on 24/04/2017 at 14:12

          You are right that it’s only a speculation, and I’m not saying it wouldn’t be possible for boron to have some other mechanism of increasing estrogen.

          As for the percentages not adding up, the normal range of testosterone is 250-1200 ng/dL and the normal range of estrogen is around 2.5-5.5 ng/dL. So 15% increase in T would be plenty enough to raise estrogen by 50% if aromatase enzyme is high enough.

          • Manos Vr on 24/04/2017 at 17:28

            You have a point there.To be honest, I wasnt aware of the T to E ratio.Only thing that remains now is that it tends to lower HDL,but thats not that big of a deal. I could delete my previous comments if you want, since you shed some light on the matter.Cheers

  16. Robert on 09/05/2017 at 10:55

    That version of boron in your link is the best I’ve used and only that doesn’t make me feel crappy.
