Testosterone booster supplements are dietary supplements that are claimed to increase testosterone levels in men.

Testosterone is a hormone that is important for the development and maintenance of male characteristics, such as muscle mass and strength, body hair, and a deep voice.

Testosterone levels naturally decline with age, and some men may experience a decline in testosterone production due to other factors, such as certain medical conditions or treatments.

Testosterone booster supplements may contain a variety of ingredients, such as herbs, vitamins, minerals, and other nutrients, and are marketed as a way to increase testosterone levels naturally.
