Magnesium plays a crucial role in protein synthesis, muscle and nerve function, blood glucose regulation, and blood pressure control. Approximately 2-3% of the total testosterone in the body is in the free form. Testosterone can bind to proteins such as sex hormone-binding globulin (SHBG) or albumin, which transport it throughout the body but render it biologically inactive. Approximately 2-3% of testosterone in the body is free, while the remainder is bound to proteins. On the other hand, unbound testosterone, often referred to as "free testosterone," is biologically active and exerts its effects on the body. Getting to this range from higher body fat levels will improve testosterone. Dieting below 10 percent body fat for men typically causes hormonal disruption because your body interprets extreme leanness as a survival threat and downregulates reproductive hormones. Going from six hours of fragmented sleep to eight hours of quality sleep can increase testosterone by 200 to 300 ng/dL without any other intervention. Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition. You are fully responsible for paying for all health care services but will be entitled to receive a discount from those health care providers in accordance with the specific pre-negotiated discounted fee schedule. The cost of at-home testosterone testing kits varies, with costs ranging from $50 to $200. In some instances, insurance may fully or partially cover the costs of in-person or at-home testosterone testing. There are at-home testing kits available online, but the results are best discussed with a healthcare provider. Emerging evidence also suggests that Vitamin K2 plays a role in mitochondrial health. This arterial calcification can lead to stiff, narrowed blood vessels, which impairs circulation. Vitamin K2 has been shown to support the expression and activity of CYP11A. The PKA pathway is responsible for activating enzymes that are essential for "steroidogenesis"—the creation of steroid hormones. These cells take cholesterol and convert it into testosterone through a complex, multi-step process. When we correct deficiency, we’re not "boosting" the body — we’re restoring it. Over years of clinical practice, magnesium has consistently been one of the most rewarding minerals to optimise. Magnesium thrives within a total-health framework, not in isolation. However, the biological mechanisms—such as the activation of the PKA pathway and osteocalcin—suggest that Vitamin K2 may support the body's natural ability to maintain healthy testosterone levels. While Vitamin K2 may support healthy testosterone levels, it works best when paired with a lifestyle that prioritizes hormonal health. A review of dozens of clinical trials showed that DHEA supplements do increase blood testosterone levels in men and women.
