Taurine may be the key to essential tremors!
About a year ago I developed shaking of both hands (action tremor). This developed suddenly and I was experiencing some other symptoms as well that led my doctor to believe I could have Hyperthyroidism. Tests came back negative for Hyperthyroidism, but I do have antibodies against my thyroid, so the doctor started me on Selenium and a Gluten-free diet. I also had pretty severe iron-deficiency anemia, and mild B-12 & vitamin D deficiency. I felt better after those things were corrected, but the tremors continued as well as the foot/leg cramps and eyelid twitching I had been experiencing. This led the doctor to believe I could be Magnesium deficient. I began taking 460mg of a high quality Magnesium Glycinate supplement. The cramps & twitching resolved (other than occasional cramps), but the tremors only improved a little.
At this point, I was frustrated, upset & worried that I had developed Essential Tremor. I have no family history of ET & come from a very large family; I even knew my extended family & no one had ET. It's possible for it to develop in someone without a family history of course, but I'm in my 40's & wanted to be sure I tried to thoroughly get to the bottom of this before resigning myself to the ET diagnosis.
I started doing some research & came across information about l-theanine being helpful for tremors, so I began taking 200mg twice daily. This helped a lot, but the tremors weren't completely gone. The doctor suggested increasing my dosage of Magnesium, but I have trouble tolerating the higher doses (even of the glycinate).
During my research, I found the Earth Clinic website & was encouraged by the tremor-reducing suggestions. I added 500mg of Taurine once/day a few days ago & my tremor is 99% gone! In fact, if I wasn't so sensitive to it, I wouldn't know I had it at all. It's too early to assume that the Taurine, l-Theanine, Magnesium combo will continue to work, but I'm very encouraged!
Sorry for the long post, but if I can help anyone going through a similar situation, I want to be detailed as to what is working for me in case someone is going through the same thing.
*A positive side effect of taking the l-theanine & taurine is improved mood & less anxiety/stress.
You likely have a magnesium deficiency that is being exacerbated by the large amount of Vitamin D that you are taking. The same thing happened to me. Vitamin D needs magnesium to convert it into a usable form. The large amount you are taking is sucking up all your magnesium. Trembling and hand tremors are a result. Please research how to take Vitamin D with magnesium.
A few years back, my husband developed an essential (or intention) tremor in his hands. At first it bothered him only when upset or tired, but gradually started to affect him full time. As my husband makes his living as an OR nurse and needs to have fine motor skills for his job performance, it became imperative to find a treatment or cure. After researching the problem, we decided to hit him with the whole shebang of potential treatments. The most important seemed to be Magnesium L-threonate, GABA, Taurine, and L-theanine. Fortunately, as some have mentioned, the Magnesium L-threonate does not cause or aggravate diarrhea. I am really happy to report that my husband's tremor has basically disappeared. He takes other supplements also, but was taking them prior to the onset of the tremors. We have also eliminated any aspartame and eat only very small amounts of gluten. I am not sure if I am allowed to mention a specific product, but there is a tablet available from a reputable "Source" that contains the combo of GABA, Taurine, L-Theanine, Magnesium chelate, and some herbal extracts that simplifies the process. He adds a Magnesium L-Threonate product from the same "Source" to that tablet. All the best and hope this works for you as well.
