Borax causes men to produce more testosterone and women more estriol. For those of us older than 40 or 50, that would seem a very good thing.

Taking 2 or 3 days a week off the borax is to (supposedly) allow your body to adjust and your hormones to balance.

Several people take borax continuously and don't seem to suffer any ill effects. As usual, do your homework and make responsible choices. However, if taking borax 4 or 5 days a week gives you the results you want, why take it for 7?

Many health professionals advise taking even your regular supplements only 5 days a week (or 3 weeks on and 1 week off). The reason for this is because anything we take continuously may attenuate -- become less effective or even ineffective. This happens all the time with prescription drugs. People who were taking MSM every single day and getting great results suddenly were not: The MSM just stopped working for them after 6 months, a year, or in some cases many years.

Hi Bridget~ I was wondering the same thing. I did a bit of internet snooping & found these articles helpful. My husband was diagnosed with Low-T, with blood levels @ 180. The doctor put him on one of the gel treatments. He felt much better @ week 2 of treatment, but has gradually been feeling worse again. We are now @ about week 4. I suspect his estrogen levels are playing a part in this. Anyway, after reading the abstract I'm sending him to Wal-mart tomorrow bright & early to get some 20 mule-team borax!

I hope this is helpful!

The research I've done on borax, suggests it's a natural hormone replacement therapy. So no worries in that department.

Hi Carolyn,

While I am a huge fan of borax and borax contains boron and boron at a fairly low dose (3mg/day) can markedly raise testosterone levels and raise 17 beta-estradiol, which depending on exactly what type of hormonal breast cancer you had, may be a problem. As such, it would be safest to confer with your oncologist before starting a boron or borax regimen. Here is a link to the study abstract :

https://pubmed.ncbi.nlm.nih.gov/3678698/#:~:text=A study examined the effects of dietary, more marked when dietary magnesium was low.

Here is a relevant study quote :

' Boron supplementation markedly elevated the serum concentrations of 17 beta-estradiol and testosterone; the elevation seemed more marked when dietary magnesium was low.'

I want to err on the side of caution given your hormonal breast cancer history, especially since the dose of borax often used for arthritis delivers much higher than 3 mg/day of boron. My dose is thought to deliver about 110 mg of boron. The female dose would be about half of that at 55 mg/day of boron. I would definitely check with your oncologist first. You can say you are considering adding a boron supplement for bone health if you think that will sit better with your oncologist and then your oncologist can make their recommendation based on that. You can also ask what the oncologist would recommend as far as boron dosing for bone health and that will let you know if borax is a potential option for you or not.

I would like to know what effects the Borax protocol would actually have on hormones. I have had fibromyalgia for over 25 years and now have arthritis so terribly I can hardly move across my kitchen. I have had breast cancer however. It was estrogen and progesterone positive. I had a low grade form of cancer and had it removed at biopsy. I did not take radiation or tamoxifen which was offered but chose to increase my iodine level. I don't want to antagonize my cancer by doing the wrong thing. I have taken so many years of over the counter pain relievers I am afraid I can't do it much longer. Any thoughts would be appreciated.

Does anyone know if taking borax is not good if you've had hormonal breast cancer
