Nutritional supplements containing boron

In 1987, Nielsen et al.We investigated the effects of boron supplementation, aluminum and magnesium in the mineral metabolism in postmenopausal women.The results showed that dietary supplements of boron in an amount of 3 mg per day maintenance serum testosterone increased from 0.3 ng to 0.6 dl.Many companies that manufacture additives quickly realized that a high level of testosterone is associated with increased muscle mass and decreasing fat.The market was soon filled with additives "testosterone booster" containing boron.

main functions of boron

  • natural power of testosterone synthesis.
  • Increases muscle mass.
  • reduces fat mass.

results

Research Companies producing additives used the Nielsen data for the start of production of products containing boron and claiming to be "natural" alternatives to anabolic steroids.However, these companies do not specify that the studies were carried out on 12 women after the menopause between the ages of 48 to 82 years, and estradiol levels have also increa

sed, and the composition of the body was not determined.Furthermore, normal male testoterona was approximately 10 times higher than the results obtained by Nielsen.

Green, Ferrando have chosen a more appropriate group to study the ergogenic effect - 10 bodybuilders.They consumed 2.5 mg boron per day or placebo and trained for 7 weeks.Increases testosterone levels were found.The researchers concluded that the boron supplements have no anabolic effect.

Recommendations Boron is a micronutrient elements, which in small quantities contained in raisins, plums, nuts, apple puree and grape juice.RDA does not provide standards for boron, although some studies suggest that a person needs about 0.5-1.0 mg of boron per day;Boron 10 mg per day apparently harmless, but more than 50 mg per day of boron can cause toxicity, which manifests itself in a loss of appetite, and gastrointestinal disorders.Some studies suggest that boron may play a modest role in the mineral status of the bone, but the signs of ergogenic means it does not show.
