Yes!! to bio-identical hormones! That's what I learned when I researched the Pill question (I turn 86 in a couple of weeks, so this was a much bigger mystery then for me). I've been on either Armour thyroid or compounded thyroid and Biest (80-20) ever since.
There is a lot more individual biochemistry than one might imagine. My father too had his first heart attack in his 50s, and several more before he died at 89. He had low blood pressure, while everyone else in the family had high blood pressure.
I also learned that I am incredibly sensitive to carbs - first from a medical psychic in California, soon confirmed by an actual doctor who told me I was pre-diabetic. In the course of eating low-carb I had to deal with a number of other doctors who swore this would kill me. I thought they could be right, so I needed to research fats. That's how I discovered that the most important factor was fat: and surprisingly to many, it turns out that the healthiest fat is natural fat in its natural state, not
processed or manipulated. This fat is crucial for basic health - the function of hormones, absorption of some vitamins and other nutrients, and the cell walls themselves. Butter. Olive oil. Macadamia oil. Coconut oil. Not seed oils or "vegetable oil", which is banned in my kitchen but ubiquitous everywhere else. Fortunately I had a good friend who was a major figure at the Howard Hughes Institute in Berkeley who could explain to me that the good natural fats protect our cell walls and keep them flexible. Oxidized fat is very bad for this process - and the research on eggs, for instance, was done on powdered eggs for convenience in the lab, which is probably how eggs became the devil, despite the fact that the healthiest people in the world, the Japanese and the French, also eat the most eggs. I published a book on my research and was lucky to get an introduction from Dr. Barry Sears at Harvard, a leading figure in the field of fats research. I still think the quality of the fats in your diet is the single most important element.
Later I went to a noted diagnostician at UNC who famously threatened to sue anyone who tested his cholesterol levels. He gave me some unusual tests but didn't find anything unusual. I banned cholesterol tests too, though I allow them now that I know more is better for most women - but yes, not for those who have genetic cholesterol disease.
I will check out LEVQ10 - thank you!!
