One needs a proper amount of testosterone to grow and function in a normal and healthy manner. Getting your testosterone levels checked is as simple as having a blood test. "The best way to boost ones testosterone levels is by increasing protein intake that is natural, like soy, meat, fish, eggs, lentils, etc. It is also very important to have a balanced diet and reduce or completely cut down on nicotine or alcohol consumption," says Dr Ajith. One must also engage in some form of exercise to stay fit and avoid supplements without consulting a professional.
