Most people know that testosterone plays a huge role in men's health and wellness. Still, many don't understand the details of the science behind testosterone levels. Every man can benefit from learning more about testosterone and how it affects the body. Free testosterone is one aspect worth knowing more about.

Free testosterone is the testosterone in the blood that is bioavailable. It is 'free' because it is unattached to any protein. Most testosterone is attached to one of two proteins: albumin and sex hormone-binding globulin. While overall testosterone levels are important, levels of free testosterone are also key because free testosterone is the type of testosterone that is easily usable by the body.
Testosterone that is attached, or bound, to proteins is not available to androgen receptors. Only free testosterone can interact with androgen receptors. Androgen receptors are a kind of hormone that plays a hugely important role in many aspects of bodily function. The reproductive, cardiovascular, neural, immune, and musculoskeletal systems all rely on androgen receptors and, thus, on free testosterone.
While bound testosterone plays a vital role in the body, many bodily functions can only be stimulated by free testosterone. The functions of free testosterone include enhancing sleep quality and duration, improving sexual functioning, increasing energy and endurance, and raising red blood cell production. Other functions are to balance cholesterol and blood pressure levels, support bone strength, support muscle strength, promote a healthy weight by stimulating metabolic function, and enhance memory and focus.
The levels of testosterone in the blood are affected by aging. As a man gets older, his levels of both free testosterone and overall testosterone naturally drop. What is considered a normal free testosterone level is determined by a man's age. The same goes for overall testosterone levels.
Testosterone peaks in a man's late teens, and starts to gradually decline after the age of 30. At this stage, testosterone levels will decline by about 1% each year. Testosterone is measured by nanograms per deciliter.
Puberty onset (transition from Tanner stage I to Tanner stage II) occurs for boys at a median age of 11.5 (+/-2) years and for girls at a median age of 10.5 (+/-2) years. There is evidence that it may occur up to 1 year earlier in obese girls and in African American girls. For boys, there is no definite proven relationship between puberty onset and body weight or ethnic origin. Progression through Tanner stages is variable. Tanner stage V (young adult) should be reached by age 18.
While testosterone levels do naturally drop over the years, not all decreases in testosterone are non-problematic. Low testosterone is a medical condition, occurring when the amount of testosterone in the blood drops below the normal range.
Low testosterone levels are a major problem for any man. Low testosterone causes a wide variety of health issues. Among the problems that low testosterone can cause are low sex drive, increased body fat, loss of muscle mass, fatigue, hair loss, and decreased bone mass. While testosterone replacement therapy is sometimes necessary to counteract low testosterone, lifestyle changes are often all that is needed.
Even men who do not technically have low testosterone will benefit from higher testosterone levels. While some testosterone losses over the years are inevitable, slowing those declines as much as possible should be the goal.
Eating a nutritious diet, losing weight, reducing stress, getting good sleep, and practicing strength training are some of the ways to counteract low testosterone and fight against the nasty symptoms described above.

Testosterone plays a significant role in the health and well-being of men. For crucial processes like sperm production, sex drive, and bone mass development, the body needs testosterone. But as you age, your testosterone levels start to decrease.
If you’re 50 or older, you may have low testosterone. It’s pretty common among men starting at 50 years old. Whether you know you’re experiencing low T or are looking for a way to increase your levels naturally, continue reading to learn the benefits of testosterone for men over 50.
Protein, the building block of our body. It’s essential for building and maintaining muscle tissue, strength, and overall good health. Foods like lean meats, fish, kale, nuts, and whole grains are great sources of protein and can be easily added to your diet. But how much protein does your body actually need?
It’s no secret that many experience muscle mass decline as they get older, but that doesn’t mean you have to accept it. With proper calculation, you can easily determine the amount of protein you need to repair and rebuild muscle tissue. Here are some ways to determine the amount of protein you should consume.
They say sore muscles are a sign that you’re doing it right at the gym. But let’s be honest, no one likes waking up to intensely sore muscles. Wondering if you can speed up muscle recovery, and what helps muscles recover faster?
While most muscle soreness resolves on its own after a few days, you probably won’t want to wait it out. Not only can it be uncomfortable, you likely want to get back to exercising. Let’s look at what causes soreness and how to speed up muscle recovery.
