Are there any advantages to human growth hormone?

Ask the doctor

Q. I've heard about the benefits of human growth hormone (HGH) for older individuals. Is this something I should try?

A. The benefits of HGH supplementation for older adults are unproven, and perhaps most telling is that these products have a negligible effect on HGH levels. In addition, there are concerns about potential side effects.

HGH comes in two forms: injections and pills. Since HGH injections are difficult to administer, pills are often preferred. Yet, these supplements do not actually contain HGH like injections do, because the hormone would quickly break down in the digestive tract. Instead, they contain amino acids that are absorbed by the body, which raises HGH levels. (They are also more expensive and can cost $100-plus for a month's supply.)
