促角物质和合成类固醇广泛使用，特别是在非专业运动员中。为了避免药物滥用的副作用，建议成功的关键是适当的运动营养。它是营养健康食品的均衡摄入，含有适当混合的必需营养素。人类生理学和营养学的知识已经大大增加，因此也有应用改变饮食和补充特定营养素。调节膳食成分和/或补充特定营养素，以改善人类的身体机能，是一种有效的营养促人体运动辅助物的定义。硼是一种微量元素营养素，最近有研究表明，硼的补充可以增加血浆类固醇激素的浓度。在单盲交叉试验中，血浆17-B雌二醇（E2）浓度显著升高（P<0.004），血浆睾酮(T)水平有升高趋势。E2/T比值显著升高。然而，血浆脂质没有受到扰动。此外，在另外两项以成年雄性大鼠为实验对象的研究中，还探讨了硼对类固醇生成的影响及其机制。补充硼导致内源性类固醇激素的升高，这表明硼可能作为运动员的一种安全物质，值得进一步研究。
Ergogenic substances and synthetic steroids have a wide spread use, particularly among nonprofessional athletes. To avoid the side-effect of drug abuse, it is suggested that the key to success is a proper athletic nutrition. It is a balanced intake of nutritional wholesome foods that contain a proper blend of essential nutrients. Knowledge of human physiology and nutrition has increased greatly, and so has application of dietary alterations and supplementation with specific nutrients. Modulation of dietary composition and/or supplementation with specific nutrients with the intent of improving human physical performance is a working definition of nutritional ergogenic aids. Boron is a trace element nutrient, and recently its supplements have been shown to increase the concentration of plasma steroid hormones. In a single blind cross-over trial, it resulted in a significant increase in plasma 17-B estradiol (E2) concentration (P<0.004) and there was a trend for plasma testosterone (T) levels to be increased. The ratio of E2/T increased significantly. However, there was no perturbation in plasma lipids. Furthermore, the effect of boron on steroidogenesis and its mechanism was also investigated in two more studies conducted on adult male rats. The elevation of endogenous steroid hormones as a result of boron supplementation suggest that boron may be used as an ergogenic safe substance for athletes which should be further investigated.
