In a Nutshell

Dr. Kyle Gillett emphasizes foundational lifestyle pillars—diet with adequate protein, fiber, and calories, vigorous exercise 3-4x weekly, sleep, stress management, and purpose—for natural hormone optimization in males. Key supplements include creatine, tongkat ali, fadogia, L-carnitine, vitamin D, and boron to support testosterone, DHT balance, and androgen receptor density, with monitoring of SHBG and free testosterone. Exogenous testosterone or clomiphene is rarely recommended for young men with normal levels due to fertility risks and side effects, while low-dose tadalafil may aid prostate health and blood flow.

Dr. Kyle Gillett recommends treating hormone optimization like a new car coming off the assembly line by performing a full scope of diagnostic workup and monitoring progress across a person's lifespan. Development continues throughout life, so ongoing monitoring is essential.

Testosterone should be measured either as total testosterone with SHBG or as free testosterone. SHBG (sex hormone binding globulin) is the protein that binds up all androgens and estrogens in the body. The stronger the androgen, the stronger it binds. During puberty, strong androgens like DHT (the strongest bioidentical androgen) play a prominent role in secondary sexual characteristics. High SHBG means DHT can run higher because it is not metabolized, but there is less free DHT. The goal is balancing enough free DHT and enough total DHT.

Blood work follow-up is recommended at approximately 6 months using shared decision-making with a physician.

Diet and exercise are the first two pillars. During puberty, sleep is particularly important. Throughout the lifespan, do not exclude things that are helping you. During puberty, consuming dairy can help increase IGF-1 and free IGF-1. IGF-1 helps with growth, genital development, secondary sexual characteristics, long bone growth, skin growth, and hair growth.

Adequate vitamin D is important because it helps with testosterone production, bone mineralization, and stature. Up to approximately age 25, optimizing growth hormone and IGF-1 helps with bone density and bone growth. From a dietary standpoint, having enough free estrogen (not too much) during growth helps stockpile bone to prevent osteoporosis risk later in life.

Most people benefit from eating a combination of quality proteins from animal and non-animal sources, fruits, vegetables, and starches. A pure carnivore or pure vegan diet in the early 20s and teens is a poor idea because it is likely to significantly decrease free androgens, resulting in less testosterone acting on receptors throughout the body. In late 20s, it might be a reasonable option.

Fiber is paramount for setting the set point of the gut microbiome for the rest of life. Prebiotic fiber acts as fish food for good gut microbiome. The gut microbiome is like an aquarium or fish tank where food either skews it toward beneficial or detrimental states.

Prebiotic fiber and essential fatty acids are important throughout the lifespan, but particularly in teenage years through 30s because they help with brain development.

If an individual is overweight with excess adipose tissue, caloric restriction and exercise done not too fast and in a healthy way is beneficial for testosterone in the long run. For individuals not carrying excess body fat, caloric restriction lowers testosterone. In a caloric deficit, there are less building blocks for hormones, a more catabolic state, less signaling from growth hormone and IGF-1, and higher SHBG, causing free androgens and free estrogens to decrease.
