What Is Testosterone?

Testosterone is known as the “male sex hormone,” but it is also necessary for female functioning as well. In men, testosterone is produced mainly in the testicles (95%), with a small amount in the adrenal gland (5%), Testosterone production and levels are controlled by the hypothalamus and the pituitary gland (a.k.a. “master gland”).


What does Testosterone do?

Testosterone plays a primary role in the normal growth and development of the male sex and reproductive organs. It also plays an essential role in male fertility and sexual performance and is responsible for all the characteristics we typically associate with being a man.

Testosterone, however, is not just a sex hormone. With receptor sites in the heart, brain, and throughout the entire body, testosterone also pays many other critical roles:

  • Muscle mass & strength
  • Bone growth & density (strength)
  • Male fat distribution
  • Energy & Stamina
  • Proper heart function
  • Glucose, lipids, and cholesterol metabolism
  • Red blood cell production
  • Immune system health
  • Mental well-being and cognitive functions


What is Low Testosterone?

Simply having low levels of testosterone does not necessarily mean that a man has Low-T. The amount of testosterone in men can range from 300 to 1100 ng/ml. Some men have low levels of testosterone, and feel well and do not experience any symptoms, while other men with the same levels of testosterone experience symptoms that affects their quality of daily life.


What Causes Low Testosterone?

Hormone changes are a natural part of aging. In men, testosterone increases during puberty, generally peaks in early adulthood, and begins to decline after the age of 30. After 30, the levels gradually decline by an average of 1% per year and continue well into golden years.

This decline becomes more evident in middle age, when some men begin to experience the effects of low testosterone, or what has become known as "Low-T."

Other Causes of Low Testosterone

In addition to aging, low testosterone has many other potential causes and usually is multifactorial.

  • Insulin Resistance & Diabetes
  • Metabolic Syndrome
  • Obesity
  • Poor Diet & Lifestyle
  • Environmental toxicity
  • Medications
  • Other hormone imbalances

Professional Grade Supplements

Professional-Grade Supplements

Depending on your specific needs and goals, we may use evidence-led professional-grade supplements as part of your treatment protocol. These supplements contain different natural substances, which may include vitamins, minerals, essential fatty acids (i.e. fish oils), botanical medicines, animal tissue (e.g. glandulars), and other therapeutic natural substances.

Botanical Medicine

Botanical Medicine is the use of plants to treat disease and promote health.  Plants have been used in this way by many cultures, from pre-history to today.  According to the World Health Organization, over 25% of modern drug medicines are derived from plants with similar traditional uses. 

Plant substances are powerful medicines.  When used in proper dose and combinations, botanical medicines are safe and effective, producing few, if any, side effects.  However, certain botanical medicines are more powerful and need to be used with caution, as they can be toxic in large amounts.  In many cases it is possible to take certain botanicals with certain medications.  However, there can be “herb-drug” interactions.
