We only recommend supplements with strong scientific evidence supporting their effectiveness. It lowers estradiol (a form of estrogen made mainly by the ovaries) levels by almost half, too. Also, vitamin K2 is even more necessary for bone and cardiovascular health than vitamin D. While it's not a bad choice, vitamin K2 stays in the body LONGER and is also more easily absorbed into the body. After all, they contain natural ingredients that are good for the body. We only recommend supplements that provide the best value for money. We evaluated the overall value of each vitamin and mineral supplement, considering its effectiveness, safety, product transparency, manufacturer reputation, and price. We only recommend supplements that contain vitamins and minerals in amounts that are effective. This mineral is involved in many processes in the body, and maintaining a high magnesium intake can also help increase testosterone and sperm levels. One animal study showed that vitamin K2 can support testosterone production in testes.(11) Functional measurements of sperm can be improved too. Vitamin D3 can increase a man's testosterone levels by 20%, but the effect seems to be more pronounced in those who have a vitamin D deficiency.(2) One way to boost testosterone levels naturally is to have balanced estrogen levels. It also regulates cortisol—the stress hormone that directly inhibits testosterone production. A study involving athletes has shown that calcium supplements cause a greater increase in levels of testosterone compared to those who do not supplement with calcium.(12) Unfortunately, more research is still needed to find out if taking vitamin A supplements is effective for increasing testosterone levels. Below, we list the most useful vitamins and minerals that can address decreased testosterone levels. Just like any process in the human body, optimal testosterone production needs a sufficient supply of many essential nutrients from both diet and supplements. In this detailed guide, you'll learn more about the eight top vitamins and minerals to boost testosterone levels. While the evidence is mixed, some studies suggest that high soy intake (particularly from isolated soy protein powders) may reduce testosterone levels in certain individuals, likely due to competitive binding at estrogen receptors. Vitamin D3, technically a prohormone, has receptor sites in Leydig cells and has been shown in multiple studies to correlate with testosterone levels. A 2022 study found that taking 300 milligrams (mg) of ashwagandha root extract two times daily for 8 weeks helped increase testosterone levels and sexual well-being. Some herbs and supplements may help your body make testosterone, while others may help relieve symptoms of low testosterone. Furthermore, if you’re over the age of 30, additional supplementation of Zinc and Magnesium will help improve testosterone levels and improve your overall quality of life and boost testosterone. That makes vitamin B3 a testosterone booster, important for amplifying testosterone levels. For instance, some herbs, vitamins, or supplements may interact with other medications or supplements that you’re taking. Animal studies from 2020 and 2019 show that L-arginine may help to raise testosterone levels in rodents. Because of that, you might not need a separate supplement in addition to your testosterone booster. Supplements are only meant to supplement insufficient dietary intake, not fully replace it. If you're dealing with low testosterone, you should focus on getting it back to normal levels by fixing your diet, sleep routine, lifestyle, and exercising regularly. You can also find Magnesium and Zinc in dietary supplements. This study shows that vitamin B12 can impact testicular health. Vitamin B9, crucial for tissue growth and DNA repair, especially in teenagers, has limited research linking it directly to testosterone levels. An imbalance between estrogen and testosterone may lead to infertility because high estrogen may slow down sperm production . On the flip side, deficiency in vitamin B6 leads to the production of estrogen. Vitamin B2 prevents 5 alpha-reductase enzymes from converting testosterone to another hormone called Dihydrotestosterone (DHT), maintaining optimal T levels 6,7.
