I have multiple sclerosis and I was been in an car-accident fiwe years ago. My back opereated and stiffened with titan. I have had much of pains. This Carlsons D3-vitamin was helpped me and all my wellness was been more best, even I don`t need the painpills any more or very rarely. I`m very thankful of this vitamin + withoute carbohydratete meal. I don`t need sleep today only 7 hours, before 10-12 hours. Ji-huu! All my life is changes, my mind is vigour. I really suggest first to go to the doctor who knows and appreciate from this like medicine. Thank You!
