my wife [53 - Chinese by race, born in Malaysia but now living in Singapore] suffers from dizziness and nausea to the extend of falling over. She is in Singapore hospital right now. She had a MRI scan but it showed NO abnormalities [yes they found a brain - lol]. They taken a blood test and determined that she has a D3 deficiency of 9 while 35 is apparently normal . I spend time this morning on the net but can t confirm her symptoms with D3 deficiency. She takes 6 x 1000mg fish oil capsules a day for the last year [Fish liver oils, such as cod liver oil, 1 Tablespoon (15 ml) provides 1,360 IU (90.6 IU/ml)] She has a 95% Asian diet, very little physical exercise, VERY little exposure to sunlight [tan is NOT hip in Asia]. She is overweight by say 15kg, [plumb but not FAT or obese]. I just like a second oppinion on the symptome versa the diagnosis please. Thank you Helmut Samerski
