I came across this thread by user u/Crockett (am I allowed to tag?) suggesting that big pharma gave boron bad press: https://communities.win/c/Health/p/15JnKfThq8/boron/c and I'm gonna post the content he wrote, what do you guys think?

Some facts about boron:

Boron helps calcium and magnesium levels, by regulating tissue membranes so the minerals can be pumped in and out as needed more easily. This means more calcium freed from muscle tissue, and less needs to be released from bones. Calcium level can improve just by taking Boron and magnesium, which is sufficient for calcium to be better allocated in the body.
Boron helps regulate sexual hormones. It increases testosterone and estriadol in post-menopausal women, relieving symptoms of menopause. In younger men, it increases testosterone but actually decreases estrogen. There's no evidence that it causes hormone levels to increase beyond what's healthy
Boron lengthens the half-life of sexual hormones and Vitamin D in the body, significantly increasing their presence in the blood and bio-availability over time.
Boron significantly reduces certain markers for inflammation. As you probably know, heart disease and many others are basically just diseases of inflammation.
Boron helps reverse fluoridation
Boron helps detox heavy metals
Borax (yes, the cleaning stuff) is pretty much just boron, and has been used to basically cure arthritis and osteoporosis, thanks to its anti-inflammatory, bone-healthy, and hormonal effects
Borax has been banned in the EU and Australia as a "reproductive poison", even though it is no more toxic than table salt
Borax was labeled a poison in Australia immediately following pharma lobbying the government after finding out that someone was selling it as a cure for arthritis
Borax is anti-microbial and anti-parasitic, but especially anti-fungal. It is an effective treatment for athlete's foot, vaginal thrush, and candida
Boron protects DNA damage, which is the basic mechanism of causes of cancer
Boron exposure has been shown to correlate with lower risk of osteoporosis and cancer
Studies suggest that boron helps cognitive function as well
Boron is naturally acquired from most plants we would eat. But boron content suffers seriously from soil depletion. Plants grown in mineral depleted soil, or with growth stimulated by fertilizers, will be lower in boron than they would have been in more natural history
There is no established daily recommended amount of boron, despite its health impact (it's effect on bone health alone should merit it for attention)
Those who recommend boron recommend a dosage of 6-9 mg/day, and even higher for the treatment of acute symptoms, before reducing to a lower dose for maintenance
The LD50 (measure of fatal toxicity) is a thousand times higher than any typical dose
Studies suggesting that it is harmful to fertility required doses far beyond any dosage or exposure, and was only demonstrated in animals, never in humans (even among boron miners)
Studies suggesting that is ineffective for its claimed uses used negligible amounts of it (less than the 3 mg/day)

TLDR:

Great for Bone/teeth health and calcium/magnesium levels in general
Great for Inflammation
Great for sexual hormones
Great anti-fungal
Basically cures Osteoporosis and arthritis
Good for fluoride and heavy metal detox
Possible cognitive and anti-cancer benefits
Suppressed by pharma because it's cheap and unpatentable
Modern people don't get enough because factory farming and food processing means we get it from nowhere instead of everywhere
