Creatine

Creatine is one of the most highly scrutinized workout supplement on the market, with over 700 unique scientific papers published on it¹⁾.

One of the biggest benefits to creatine supplementation, particularly for beard growth, is its ability to increase testosterone²⁾ and dihydrotestosterone, the androgens responsible for facial hair growth and maturation.

One of the most popularly referenced studies regarding this is a 2009 study done by the Department of Physiological Sciences, Stellenbosch University, Stellenbosch, South Africa.

RESULTS: After 7 days of creatine loading, or a further 14 days of creatine maintenance dose, serum T levels did not change. However, levels of DHT increased by 56% after 7 days of creatine loading and remained 40% above baseline after 14 days maintenance (P < 0.001). The ratio of DHT:T also increased by 36% after 7 days creatine supplementation and remained elevated by 22% after the maintenance dose (P < 0.01).
