For Vitamin D Deficiency "I'm hoping for the best. I have been terribly sick for years and just took my first dose of weekly D2, 50,000 units. Lately, my sickness was getting unbearable. Felt sick and weak constantly. My hair is falling out, my skin is awful. I had no idea I had low vitamin D until my PCP did lab work. Fingers crossed I get better."

For Vitamin D Deficiency "After a routine blood test for a physical, it was discovered that I had a vitamin D deficiency. My Dr. recommended ergocalciferol 50,000 IU capsules once a week for 12 weeks. Around 6 hours after I took that first dose, I woke up confused and weak, it was the worst day of my life. My personality changed completely, I thought I was going crazy. I cried, I was screaming, I couldn't even stand up from my bed. At some point, I passed out for a short period, and when I finally opened my eyes, everything was spinning. My husband rushed me to the hospital, and after a few tests and a CT scan, it was determined that I had a really bad adverse reaction to the vitamin D. They gave me fluids, and I guess that's what helped me to recover."

For Vitamin D Deficiency "I had gone through a period of extreme depression and anxiety for several months. I figured that maybe there was something else going on and to stop attributing my physical and mood symptoms as purely due to my depression. I also would have these moments at random times where I felt like I could fall asleep, which was concerning me, along with neck pain and random bouts of crying. Working out had also become impossible due to muscle weakness. A severe vitamin D deficiency was found in blood work, and I began supplementation of 50,000 units. On day one, I noticed marked improvements in my depression, anxiety, energy, concentration, and physical discomfort. Of note, this takes time to build up the proper levels in your system. I noticed after five days my symptoms coming back, so you need to go ahead and keep taking it."
