For Vitamin D Deficiency "I struggle badly with Vitamin D supplements. Don't ever let a doctor tell you it's not the supplement! The only thing I do like about it is for me it's almost like a sleeping pill. I pass out very quickly after taking it every time. However, the next day I always feel tense, dizzy, short of breath, headaches, muscle aches, anxiety, stomach pains, constipation, and have acid reflux issues. This ALWAYS goes away when I stop the supplement. I've tried adding magnesium and it doesn't help."

For Vitamin D Deficiency "After my wellness checkup and blood analysis, I was told by my MD to start taking Vitamin D3-2000 daily. I took it as recommended for 2 days and I noticed that I was experiencing dizziness, tiredness, and really bad cramps in my hands, feet, and legs. I thought that I was dehydrated and drank more water. The cramps kept getting worse, and I also started having increased palpitations and more dizziness. As the only change I had made in my daily regimen was taking the D3, I decided to stop taking it to see if it might be the cause. Sure enough, these symptoms disappeared. So, why are we being told to take this? Several of my friends and family have been advised to do the same lately. Is it a new 'health' sham?"

For Vitamin D Deficiency "So my doc prescribed me 10000 IU for 6 weeks, since I was vitamin D deficient. After 2 weeks of taking these, I noticed terrible heart palpitations and a fast heartbeat. I went to the ER with a heart rate of 172, the scariest day of my life. Vitamin D makes me so drowsy and dizzy. I'm definitely not taking this anymore. It helped me with my levels, now it is 36, but it's making me feel miserable."

For Vitamin D Deficiency "I reluctantly had to go to the doctors in October last year (2024). I was suffering with exhaustion, my joints ached and they were really sore and stiff. I had this awful excessive sweating and a general feeling of feeling unwell. I was prescribed HuxD3 20,000 IU for 7 weeks. I can honestly say that I felt shocking. My legs, hands, fingers, wrists, feet, and ankles all began to swell up. Not just a little bit either, and then came this awful dizziness to the point where I couldn't even leave the house for fear of falling over. I had to nip to the local shop, which is a 10-minute walk, and it took me over 20 minutes each way because I was picking my way like an OAP. When I lifted my leg/foot to take a step, I almost went flying. My eyelids began to swell too. Due to the dizziness, I even went to A&E. I asked them if it was the meds making things worse. They denied it, but I knew it was the meds causing my problems. The only good thing about this HuxD3 was my levels went from 20-12."
