Boron’s role in the body is not completely clear but it seems to be involved in bone health.

Some studies have shown that boron influences how the body processes calcium, magnesium, vitamin D, and estrogen. This may have a resulting impact on bone mineral density.

What is boron?

Boron is an element that can be ingested in the diet. However, the amount of boron that the body needs is unknown. As a result, it is not classified as an essential vitamin or mineral. Some research has suggested that boron plays a role in health. However, at the present time, information about boron in the body is very limited.

Where does boron come from?

Boron can be consumed in the diet. It is available in foods such as avocados, dried apricots, prunes, and raisins.

What are the bone health benefits of boron?

Boron possibly has effects on the bone through a few mechanisms. One small, older study tested the effects of supplementation with 3 mg per day of boron in postmenopausal women. It found that boron supplementation decreased the amount of calcium and magnesium that was lost in the urine. Boron supplementation also elevated levels of estrogen and testosterone in the study subjects (3). Boron also extends the half-life of vitamin D and estrogen (4). Calcium, magnesium, vitamin D, and estrogen all play important roles in bone metabolism.

Studies have shown that supplementation with boron can lead to improved bone density (2). One specific study looked at the effects of eating 100 g per day of dried plums versus dried apples in osteopenic postmenopausal women. Study participants also received daily calcium and vitamin D supplementation. Although it can’t be determined whether boron was the cause, the women who ate dried plums had improved bone mineral density compared to the women who ate dried apples (1).

How much boron is recommended?

There is no recommended amount of boron that should be consumed each day. Similarly, there is no known amount of boron that may be toxic to consume. 1–3 mg per day is generally considered safe.

How does Roman offer boron?

Roman obtains boron from a non-GMO source in the USA. It is available synthetically as boron citrate.

Roman offers boron in the following supplements:

Bone Health

Boron is one of ten main ingredients in Roman’s Bone Health supplement. The supplement consists of three tablets that should be taken with water. Each individual tablet contains 1 mg of boron, for a total daily dose of 3 mg.

Other ingredients in the tablets include ascorbic acid, calcium citrate, D-alpha tocopheryl succinate, magnesium citrate, silicon dioxide, menaquinone-4, menaquinone-7, phytonadione, cholecalciferol, microcrystalline cellulose, stearic acid, dicalcium phosphate, croscarmellose sodium, magnesium stearate, and pharmaceutical glaze (shellac, povidone).

Does boron interact with any other drugs or medical conditions?

Currently, there are no well-documented instances of boron adversely interacting with other drugs or medical conditions.
