Branched-chain amino acids, or BCAAs, are another popular fitness supplement, commonly marketed for muscle growth and recovery. As is the case with whey protein, BCAAs can increase insulin and IGF-1 levels. For some people, these hormonal changes may increase oil production and contribute to clogged pores.
Testosterone and Anabolic Steroids
There’s no debate about this one. Hormonal supplements and performance-enhancing drugs have an especially strong effect on acne. Testosterone and anabolic steroids can stimulate the sebaceous glands, causing them to produce more sebum. Sebum normally protects and lubricates the skin, but getting too much of it can contribute to clogged pores and inflammation.
Sebaceous glands are commonly found on the face and scalp, and as a result hormone-related acne often appears in these areas. Some products marketed as muscle-building supplements may also contain steroid-like ingredients, making it important to choose supplements that don’t come from sketchy manufacturers.
