Scurvy In these experiments, no clinical difference was noted between men given 70 mg vitamin C per day (which produced blood levels of vitamin C of about 0.55 mg/dl, about of tissue saturation levels), and those given 10 mg per day (which produced lower blood levels). Men in the prison study developed the first signs of scurvy about 4 weeks after starting the vitamin C-free diet, whereas in the British study, six to eight months were required, possibly because the subjects were pre-loaded with a 70 mg/day supplement for six weeks before the scorbutic diet was fed. Men in both studies,
Vitamin D deficiency in Australia individual might need hours to achieve that same desired amount. The strength of the UVB changes throughout the day so time will be change accordingly. There is conflicting evidence to suggest whether obesity contributes to vitamin D deficiency. Obese individuals have an increased risk of being vitamin D deficient likely caused by lack of sun exposure from reduced mobility and or low levels of physical activity. The serum levels of obese Australian were 8.3- 9.5 nmol/L lower in both genders comparable to those of healthy weight ranges. During the AusDiab study conducted throughout Australia serum levels within obese people were
