Evidence Shows Placentophagy (Placenta Encapsulation) Works

Posted by Dr. Allison Smith on Thursday, 28 December

The practice of placentophagy – a woman consuming her placenta after she gives birth – is a bit of a hot topic these days. For those of you not familiar with the practice, if you're imagining the Dothraki queen devouring the giant, bleeding heart of a horse with her bare hands, you're probably not alone. In reality, there's much less of a "yuck" factor associated with the process when consuming an encapsulated placenta, which entails heating, dehydrating, pulverizing and then placing the resulting placenta powder into capsules. The result looks more like a vitamin supplement than a bleeding heart.

Mood and Menopause – Going Through "The Change"

Not quite menopause. Throwing blankets off at night, keeping awake. Fatigue and irritation punctuated throughout the day by heat dissipating from every pore, clouding thoughts, reinforcing forgetfulness. Hair falling out so stubbornly fast. Clothes choosing when to fit. Flooding periods coming sporadically, unexpectedly. They call it “the change of life” – but I feel like a different person altogether. What is happening?         

In perimenopause, the physiological landscape is subject to tremendous change with estradiol and progesterone at the heart of the transition. Progesterone levels fall quickly – no ovulation – no corpus luteum – no progesterone. Estradiol, on the other hand, does not give up so easily. Estradiol levels continue to rise and fall – reliable, steady, wave-like – a biological rollercoaster – approaching the halting rhythms of reproductive senescence. In the context of very low progesterone, these dramatic peaks and troughs in estradiol levels, give rise to systemic consequences and unrelenting symptoms of the menopausal transition.

Brussels Sprouts & Healthy Estrogen Metabolism

Posted by ZRT Laboratory on Friday, 21 July

Brussel Sprouts and Good EstrogenYou might ask what Brussels sprouts and estrogens are doing in the same sentence, but I am here to tell you that there is a connection.

Brussels sprouts are the cruciferous connection to healthy hormone metabolism. These age-old options –including cabbage, broccoli, bok choy and cauliflower – have gained new acclaim today as dietary super foods. These plants, cultivated for centuries and originally used as medicines, can nourish us towards superior health and hormone balance.

A Year of Saliva Testing in Research

Posted by Dr. Alison McAllister on Friday, 23 December

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 studies were published in 2016 using saliva testing – 61 studies for testosterone and 189 studies on cortisol, while poor progesterone was neglected with only 14 studies this last year.

It’s always good to know that the work that ZRT has been doing for almost 20 years in the field of saliva testing is still cutting edge and useful.
