The human body relies on minerals for every physiological process ever. Your body needs macro minerals (like calcium, magnesium, and potassium) and trace minerals in the correct concentrations for overall health.
Boron is one of these trace minerals. You may have seen it in supplements for osteoarthritis and osteoporosis.
Today, we’ll explore boron for promoting joint health, bone strength, brain function, and hormone balance. Furthermore, we’ll list the 10 best (and most bioavailable) boron supplements on the market.
Boron is a bioactive trace mineral naturally present in the environment and consumed via plant foods. Unfortunately, it flies under the radar as “nonessential” because boron deficiency is difficult to determine.
As it turns out, a small but promising pool of research suggests this trace element has numerous health benefits. It may promote testosterone production, improve cognitive performance, support joint health, and even minimize the risk of osteoporosis.
So, is it worth taking extra boron?
Let’s dig into the science.
Attention: dudes. Supplementing with boron may free up more of the good stuff (AKA testosterone) without having to turn to TRT.
Testosterone is the male sex hormone that drives muscle building, motivation, and sexual vitality. However, T levels decline with poor sleep, chronic stress, and aging.
This study on men found taking 10 mg of boron daily for one week significantly increased free testosterone levels. It also lowered levels of the female hormone estrogen AND sex hormone binding globulin (SHBG). Too much SHBG in your bloodstream makes hormones unusable, so keeping it relatively low is good.
Stanford neuroscientist Dr. Huberman has even mentioned using boron for boosting testosterone (listen to his podcast on hormone health here).
While often overlooked, boron is a critical cofactor for bone mineralization. It supports the absorption of magnesium, phosphorus, calcium, and vitamin D. These nutrients work synergistically to promote bone mineral density as you age.
This study on postmenopausal women found 3 mg of boron per day prevented urinary loss of calcium and magnesium. It also slowed the rate of bone demineralization. This is significant because declining hormone levels in menopause is a risk factor for osteoporosis.
Boron also has a close relationship with vitamin D. If your vitamin D levels are low, you may need more boron.
Boron may offer powerful protection against osteoarthritis. Researchers have found the risk of arthritis is much higher in parts of the world where boron consumption is low (0-1 mg per day).
It’s not exactly clear what the mechanism is, but boron’s role in bone mineralization may promote a healthy joint structure.
Boron deficiency has been shown to not only reduce brain activity, but also negatively impacts your performance on tasks of motor speed, and those requiring attention and short-term memory. Interestingly, these results largely mimicked what we see in people with heavy-metal toxicity. It was found that restricting boron for around a month and a half or more caused reduced cognitive performance and brain function – even more reason to ensure you’re not missing out on this key mineral.

That said, it provides just 700 mcg of boron per serving. It’s great for newbies. But if you’re looking to take boron for joint pain or hormone health, you want a product with 3 mg or more.
We chose what we believe are the best boron products on the market. But you need to make the best decision for your needs.
Here’s what we took into consideration when ranking the products.
The FDA doesn’t regulate the supplement industry. This gives dodgy companies free rein to make false claims. This makes it tricky when buying trace minerals like boron because taking too much can be dangerous.
For this reason, we only chose cGMP-certified and third party-tested products. We also prioritize companies that make their test results public.
Every dietary supplement on this list uses bioavailable forms of boron.
Plus, we included supplements containing a blend of ingredients that work synergistically to enhance boron’s benefits.
You only need a small amount of boron to see the benefits. We looked for products with doses of 700 mcg to 6 mg — this range is most commonly reported in the literature, and is considered therapeutic and safe.
Boron is an inexpensive mineral. However, when paired with other nutrients, the costs creep up.
We chose high-quality boron supplements that suit a range of budgets.
Boron is not a treatment for erectile dysfunction (ED). But if you can’t get it up due to low testosterone, upping your boron levels may offer relief.
Research has shown that boron-deficient people struggle more with cognitive performance. This older study on adults found consuming just 3.25 mg of boron improved memory and hand-eye coordination during cognitive and psycho-motor tests.
However, a supplement probably won’t offer any extra benefit if you’re getting enough boron already.
Boron and borax are not the same – they have different chemical natures and uses.
Boron is a trace mineral. On the other hand, borax is a boric acid salt used as an insecticide, household cleaner, and food preservative.
That’s a good question. After all, you get boron from avocados, potatoes, legumes, oranges, apricots, apples, raisins, prunes, and peanuts.
Unfortunately, with declining soil quality worldwide, it’s near impossible to determine how much dietary boron you’re actually getting. Not to mention that most people don’t eat enough fruit and veggies in general (this is one of the few times when vegans and vegetarians have an advantage).
Ideally, you want to consume 2-3 mg of boron minimum daily. But the average boron intake sits around 1 mg. Given the role boron plays in bone, joint, and hormone health, a supplement may be worth the investment.
Several forms of boron are well-absorbed by the body – like boron citrate, boron glycinate, and boron aspartate.
However, calcium fructoborate may be the easiest to absorb because it mimics the boron found in fruits and veggies. It’s also clinically studied to support bone health.
Calcium fructoborate is in many supplements as FruiteX B® OsteoBoron™.
As I mentioned, boron often flies under the radar. So, it doesn’t have an official recommended dietary allowance (RDA). In clinical studies, taking 3-10 mg of boron per day is most effective.
The upper tolerable limit (UL) is 20 mg per day for adults. However, you probably won’t see any additional health benefits from doses above 10-15 mg.
Boron is safe to take every day. That said, if you’re using higher doses to increase your free testosterone, some experts suggest taking it for two weeks on and one week off.
This may prevent an unwanted increase in estrogen levels from taking boron long-term.
Boron is a safe supplement taken at the suggested doses – a little goes a long way. Side effects are rare at doses at or below 20 mg per day.
That said, too much can disrupt mineral ratios and build-up in your body. It may even be fatal at doses above 20 grams (there’s no reason for anyone to take that much).
Finally, we must add the usual disclaimer about speaking to your healthcare provider before taking any new supplement.
