What is boron?
Boron is a trace mineral primarily obtained through plant-based foods in the typical diet, which explains why vegetarians and vegans generally have a higher intake than the rest of the population.
What does boron do?
Boron has not been classified as an essential nutrient for human health. While some early research suggests that boron supplementation might assist with osteoarthritis and bone health, these findings remain inconclusive. Furthermore, although boron is frequently marketed as a testosterone booster, a placebo-controlled trial failed to demonstrate any such benefit.
How much Boron should I take?
There is currently no compelling evidence to suggest that boron supplementation is necessary. However, for those who choose to take it, clinical trials have typically utilized daily doses ranging from 1 mg to 6 mg.
What did CL’s tests of boron find?
ConsumerLab.com evaluated seven boron-containing supplements, including various “bone health” formulas that featured additional ingredients. Six of these <a href="https://shoppixy.com/native-nourishers-products-we-love-from-the-best-up-and/” title=”Native Nourishers: Products We Love From The Best Up-And”>products were Approved. One combination supplement was Not Approved because it contained only 81% of the vitamin K amount stated on its packaging.
Which boron product is best?
Among the products that successfully passed quality testing and were “Approved,” CL identified a Top Pick for boron that offers a significant dose for a very low cost. CL also sought to select a Top Pick for a combination formula—containing boron alongside calcium, magnesium, vitamin D, and vitamin K—but no product met the necessary criteria for both quality and value.

How to get more boron?
Many plant-based foods, such as almonds and raisins, serve as excellentuding sodium borate, boron citrate, and calcium fructoborate; however, there is insufficient data to determine if one specific form is superior regarding side effects or absorption
Boron safety and side effects:
Boron may elevate estrogen levels, even when consumed at moderate amounts. There is also concern that it could potentially reduce phosphorus levels in the blood. Very high doses may result in adverse side effects and could potentially impact development and reproduction.
