and how does it affect me?

Studies show that as we age, our testosterone levels naturally decline after the age of 30. Although you might not think of it much at first, this hormone is responsible for a lot more than you would think. 11

Lower testosterone levels may be linked to low energy levels, libido, increased body fat, and hair loss. Having normal testosterone levels is important for good health. 12, 13
