The testosterone booster market exploits several psychological and biological realities. Exotic herbs in proprietary blends lack evidence at provided doses. If you are taking medication, are pregnant or breastfeeding, or have a medical condition, it is essential to consult with a healthcare professional before starting a new supplement. Research suggests that the MK-4 form is most active within the testes and has the strongest link to testosterone synthesis. We invite you to discover which nutrients your body needs most by taking our expert-designed quiz.
It is unclear why companies would include components in their supplements that have no evidence to support their use. For 24.8%, or 27 out of 109 individual supplements, there was data showing an increase in T with supplementation. Only 5.5% of supplements had more than two studies looking at their effect on T. In this study we sought to evaluate the composition of "T booster" supplements, their advertised claims, and we compared this with the published literature and RDA. Another study looking at the effect of red clover on the quality of life, and sexual function in men found that this supplement did not change sexual or erectile function, and resulted in a significant increase in liver transaminases . While not specified in the FDA warning, this potential risk may extend to herbal T supplements as well. Herbal supplements designed to increase T are poorly studied yet remain popular among aging men who seek to increase their T without standard TRT.
Conversely, a recent study exposing patient testes to radiation (3 patients 17Gy and 4 patients 24Gy) demonstrated normal testosterone levels up to 3 years after radiation exposure.147 Men who have had exposure of their testes during radiation therapy, either through direct or scatter radiation, are possibly at risk for low testosterone and the Panel recommends total testosterone measurement in such patients. A retrospective review of 399 men (mean age 37 years) with a mean total testosterone of 308 ng/dL found that 35% of patients had BMD at osteopenic levels and 3% had osteoporosis. Adjusted logistical regression showed an inverse relationship between total testosterone and the presence of ED, with a probability of experiencing ED increasing as total testosterone levels decreased. Where possible, clinicians should use LCMS to measure total testosterone levels to maximize accuracy and limit CV between tests in men undergoing testing, particularly in men with very low total testosterone levels.
The unique pharmacokinetic profile of testosterone pellets is due to their crystalline structure, which dissolves slowly in SQ spaces. The manufacturer-recommended dosing of IM testosterone undecanoate is 750 mg administered at weeks 0, 4, and every 10 weeks thereafter. No RCTs have compared the current formulation of IM testosterone undecanoate available in the United States to other therapies. Testosterone undecanoate is the only currently available long-acting injection therapy available as a 750 mg (3 mL) preparation and must be administered in the office under supervision.
Ashwagandha supplements have been shown in some studies to benefit male fertility and increase testosterone levels. For men with low blood testosterone levels and symptoms most likely caused by a low level, the benefits of hormone replacement therapy usually outweigh potential risks. Testosterone therapy may make sense for women who have low testosterone levels and symptoms that might be due to testosterone deficiency. Although prior studies suggested that testosterone replacement therapy increased the risk of cardiovascular disease, a large, randomized trial showed that it does not increase the risk of myocardial infarction or stroke, even in patients at high risk. Collectively, the evidence supports the role of TRT as a beneficial adjunct in managing metabolic health and potentially mitigating cardiovascular risk in appropriately selected men with testosterone deficiency, provided treatment is individualized and closely monitored.
