  • Estradiol (E2), the predominant, and most potent, circulating estrogen. It plays an important role in modulating immunity.
  • Progesterone (Pg) balances the actions of estradiol in the body and has wide-ranging physiological roles.
  • Testosterone (T) and DHEA-S (DS) help maintain libido and increase lean muscle mass and metabolic rate. In women, high T and DHEA are linked to Polycystic Ovarian Syndrome (PCOS), insulin resistance, and abdominal weight gain.
  • Sex Hormone Binding Globulin (SHBG) binds steroid hormones for transport in the bloodstream. If SHBG increases while sex steroid levels decrease, this can indicate overtraining syndrome.
  • Cortisol imbalances can create problems with blood sugar control, sleep patterns, appetite, food cravings, and the immune system. Chronically elevated cortisol is a risk factor for pre-diabetes and cardiovascular disease.
  • Thyroid Stimulating Hormone (TSH) elevations, even within the high-normal range, are linked with hypothyroidism, low metabolic rate and weight gain.
  • Free Triiodothyronine (fT3) and Free Thyroxine (fT4) imbalances indicate hypo- or hyperthyroidism. Imbalances in thyroid function can lead to low stamina, fatigue, depression, and low libido.
  • Thyroid Peroxidase (TPO) antibodies at high levels are a sign of autoimmune thyroid illness.
  • Vitamin D (D2, D3) deficiency does not have obvious symptoms but has been linked with a wide range of diseases including susceptibility to infections like flu, cardiovascular disease, osteoporosis, stroke, rheumatoid arthritis, diabetes, depression, and several cancers.
  • Fasting Insulin (In), when elevated, is a marker of insulin resistance which precedes metabolic syndrome, PCOS, and type 2 diabetes. Increased levels, particularly in concert with cortisol lead to central obesity and increased inflammatory and other cardiovascular disease markers.
  • Hemoglobin A1c (HbA1c) is an indirect measure of the average circulating glucose levels over the previous three months. Normally between 4% and 5.6%, levels between 5.7% and 6.4% are indicative of poor blood sugar control and prediabetes, while 6.5% or more is indicative of type 2 diabetes and consequently high cardiovascular disease risk.
  • Blood lipids (triglycerides, total cholesterol, HDL, LDL, and VLDL) are a barometer of cardiovascular disease risk that can be improved by fitness training and other lifestyle modifications such as better diet.
  • High-sensitivity C-reactive protein (hs-CRP) gives an indication of inflammation in the body.
  • Luteinizing Hormone (LH) is a pituitary hormone that stimulates the production of reproductive hormones. Low levels can be caused by excessive testosterone supplementation or opioid painkiller use and are seen in exercise-induced amenorrhea in women.
