Comparing Ergocalciferol vs Vitamin D2

For Vitamin D Deficiency: I am 62, recovering from 2 heart attacks, sepsis from a 4 inch liver abcess, acute diverticulitis, type 2 diabetes, severe arthritis and moderate to severe stenosis from spinal injuries to my neck and lumbar. I also tend to depression. I teach AP English at a nationally ranked high school. I love my work and don't want to retire, even when I feel bad, even though the work load is intense. When I could no longer keep up then, my PCP drew enough blood to animate Frankenstein's monster and prescribed 50,000 IU of D2. Within 24 hrs of first dose I had my best day in many months, then another and another. No side effects (not even migraines that I have suffered since age 14). Who knew vitamin D made so much a difference?

For Vitamin D Deficiency: At age 26, healthy and fit, I suffered through a hemi migraine that resulted in the appearance of a stroke. Some symptoms lasted years. I did not have a stroke, just a major migraine that caused all the textbook symptoms. Fast forward, age 32, had another hemi migraine. After many tests and blood work, I only had 4 abnormals: Copper, Vitamin D, beginning of harden veins in cebral, and an ANA positive. How can a healthy person who always had low BP, cholesterol, and none of the underlying factors get hardening of arteries?! The neurologist set me up with D2, 50,000/wk and D3,10,000/d. No adverse side effects, I don't have as much, foggy brain, depleted energy, nor the severe sensitivity to fluorescent lights. I always believed if I ate the right foods, taking supplements were not necessary. It wasn't 24hrs after taking it, that I've seen a difference, more like a gradual incline. I respect my neurologist addressing the reason for these migraines not giving me something to mask it.

For Vitamin D Deficiency: I’ve been feeling tired and weary for months now. I have severe reflux and dysphasia and GERD. Dairy allergy. I had a flare up and ended up cutting ALL dairy (I still ate a small amount at times) but since then I figured the fatigue must be a vitamin deficiency. And I was right my vitamin D level was 15. I started my 50,000 once a week vitamin D2 yesterday at 3pm. No symptoms then but couldn’t fall asleep until after 1:00am. It is now the 2nd day and I started having a lot of diarrhea around 10:00 am. And getting tired again. Praying no other side effects. I hope everyone hangs in there I know it’s frustrating. My husband doesn’t understand just how awful I feel Being vitamin defi. and no ones does until they go through it. I know you guys don’t feel the best but hang in there and if you have any strange side effects reach out to your dr to make sure you get good advise. To those feeling better- so happy for you guys !!!

For Vitamin D Deficiency: After years of chronic pain and depression that responded to nothing I finally asked for a Vitamin D blood test. BINGO. Low normal is 40 - I was a 4. After 8 weeks of once a week doses of 50,000 units, and a daily dose of 2000 units, I am feeling better than I have in years! I live in AZ - low D can happen anywhere!
