Boron is a trace mineral found in foods and the environment, also available as a dietary supplement. While not yet classified as an essential human nutrient due to ongoing research into its precise biological functions, boron is gaining recognition for its potential influence on overall health, including bone and dental health.
Understanding Boron’s Role in Dental Health
Boron supports dental health by influencing the metabolism of minerals like calcium, magnesium, and phosphorus. These minerals are fundamental for maintaining strong bones and teeth. Boron aids in the absorption of calcium and magnesium, ensuring these minerals are available for bone mineralization, the process of depositing minerals into the bone matrix. This process is important for the strength of bone structures, including the jaw that supports teeth.
Beyond mineral interactions, boron may contribute to oral health by affecting inflammation and promoting tissue repair. Boron compounds have anti-inflammatory properties, benefiting gum health and oral tissue integrity. Preliminary research suggests boron may influence cells involved in tooth building, potentially aiding future studies in bone and tooth tissue engineering. Boron has also been found in higher concentrations in non-carious teeth compared to carious teeth, suggesting a possible cariostatic, or cavity-preventing, effect.
Getting Boron Through Diet and Supplements
Boron is found in many foods, making it obtainable through a balanced diet. Good sources include:
Fruits (e.g., apples, grapes, pears, prunes)
Vegetables (e.g., leafy greens, potatoes)
Nuts
Legumes
While dietary intake is generally preferred, boron supplements are also available. These supplements typically contain 0.15 to 6 mg of elemental boron in forms like sodium borate or calcium fructoborate. Prioritizing food sources for boron is generally recommended.
Important Considerations for Boron Intake
Boron has no official recommended daily allowance (RDA) because it is not classified as an essential human nutrient. Experts suggest adults consume 1 to 13 mg of boron daily for general well-being. A safe upper intake level (UL) for boron has been established at 20 mg per day for individuals 18 years and older.
Exceeding this limit can lead to adverse effects. Given the nuances of mineral interactions and individual health needs, consulting a healthcare professional is advisable before beginning boron supplementation. This is particularly relevant for pregnant women, nursing mothers, or individuals with existing health conditions, to ensure safe and appropriate intake.
