I wanted to share a few of the studies using saliva testing that were published in the literature in 2016. Just a hint, if you want to search for articles on saliva testing, use pubmed.gov and search saliva estradiol (or progesterone, testosterone etc.). Be aware that saliva hormone testing is so standard in the research world that rarely is it mentioned in the titles of the papers. Over 310…

A Year of Saliva Testing in Research

Estrogen. We've heard Dr. Zava call it the "angel of life, and the angel of death." Too much can be hazardous. Too little can be problematic also. Not many people realize this, but estrogen plays a role in more bodily functions than just reproduction. In fact, estrogen has many important functions in the brain. Studies show that decreasing levels of estrogen can cause two of the most common…

Preventing Breast Cancer: How Hormone Balance Can Help Save Your Life

When sex hormones are tested in women either in saliva or blood spot, ZRT test reports give a ratio of progesterone (Pg) to estradiol (E2). The ratio is helpful in clinical practice when both E2 and Pg are within range, yet the patient continues to have symptoms. It is not expected to be normal or used clinically when either E2 and/or Pg are outside of their expected ranges or if the patient does…

Estrogen dominance refers to an excess of estrogen when progesterone levels are inadequate. This condition can occur in women during the reproductive years, but tends to be particularly symptomatic for women during perimenopause and in menopause. Estrogen dominance is worsened by women not ovulating, women being exposed to synthetic estrogens and/or women not metabolizing estrogens correctly.…

Breast Cancer: Fear & Preventative Double Mastectomies An Unnecessary Mix

Practical Takeaway: The liver's ability to properly metabolize estrogens has been found to affect the risk of breast cancer. Depending on which of the metabolic pathways predominate, too much of certain harmful estrogen metabolites (e.g., 4-hydroxy estrogens) can build up - and these have been found to correlate with breast and other hormone-dependent cancers.…
