Testosterone is a hormone that is produced in large amounts by males (and a little bit in females), in the testes and adrenal glands. High testosterone levels are associated with sexual performance, reproductive function, muscle mass, hair growth, aggressive, competitive behaviors, and other such manly things. Testosterone levels tend to peak at the age of 40, and slowly decline from there. Luckily, there are many things you can do to increase testosterone, so if you feel like your T levels could use a boost, you've come to the right place.
Fatty Acids. Take omega-3 tablets, or fish oil pills. Use a balanced ratio of EPA/DHA (Poliquin EPA/DHA blend is a good option). Omega-3 fatty acids lower cortisol levels in the body, giving way to higher levels of testosterone. Cortisol is a stress hormone. In order for your body to meet the demands of stress, it has to increase levels of cortisol, but also decrease levels of testosterone. Both can’t exist in your body at high levels.
