The Role of Estrogen & the Microbiome in Preserving Bone Health

I remember my great-grandmother’s hands. So capable, big and warm, covered in freckles, ready to comfort, unbending the clawed rigidity to softly wipe my tears.

I remember her powerful, beautiful mind, endless with patience, tirelessly reading my favorite story over and over from a tattered book. I remember her, trapped in a creaky body, moving slowly around the kitchen in a sort of graceful dance with pain, cooking, cleaning, all the while humming, singing to herself.

In that time and space, to my child eyes, she seemed timeless and invincible. Now all I have are the sweetest memories of her. And the photographs of her looking so lovely and so fragile. She was one of the lucky ones – no falls, no breaks, no fractures. Instead, she quietly, silently, withered, shrank onto herself, rounded back and all.

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"

Posted by Dr. Kate Placzek on Friday, 01 December

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.
