Reply To: Hi, I have been taking a 10.000 iu of VitD3 Gel caps three times a week ( Mon Wed Fri ) eg 30.000 iu a week.
I recently had a full blood test and a VitD test as well and received the results last week.
My results were 307 nmol/L or 123 ng/ml which I believe is high.
I am thin build and have been so all my life ( I weight 50kg)
I am concerned that high VitD can it seems trigger Atrial Fibrillation?
I have not had one attack of AF for nearly 4 years since adopting a LCHF Grain free lifestyle, so obviously I do not want AF to return.
So my question is please, I have no idea how long it takes for Vit D3 levels to drop after ceasing supplementation?
Should I cease taking it for say 3 months and retest? Or should I just reduce the dosage to twice a week?
Also it seems lower doses than 10.000 iu taken more frequently may be better than the larger ones? I ask as I have recently just bought another batch of the 10.000iu gel caps.
Thank you :)
