The role of vitamin D in maintaining a strong immune system is the single most censored issue in medicine. As a result, D deficiency is at epidemic proportions.
Note: 1 microgram = 40 IU’s of vitamin D, so the officially claimed maximum intake of 100 microgram mentioned in this article corresponds to 4000 IU per day. Personally I hardly ever eat fish or drink milk, my sole intake of D is from supplementation and sunshine. I take 10,000 IU per day, up to 20K or even 30K in a day if I’m coming down with something. By the next day the illness is gone. According to the mayo clinic (presumably an anti-D institution) 50,000 IU per day can be toxic.
(Natural News) Combining vitamin D-fortified foods with supplements may help ensure safe and adequate levels of the essential vitamin, a study published in the European Journal of Nutrition revealed. A team of scientists at the Technical University of Denmark pooled data from the Danish National Survey of Dietary Habits and Physical Activity (DANSDA) to carry out the study.
The research team examined the individual habitual dietary vitamin D intake of up to 855 women. The experts also conducted graded intake modelling to predict how habitual diet including fish, fortified foods — such as plain yogurt, cheese, eggs and crispbread — and supplements would help increase vitamin D levels in participants. The fortified foods provided 20 micrograms of vitamin D daily, the researchers said.
The results revealed that eating fortified foods and taking vitamin D supplements that provided up to 40 µg/day would enable the participants to attain at least 60 µg/day, which is still below the Tolerable Upper Intake Level (UL) of 100 µg/day. However, consuming fish, fortified foods, and a vitamin D supplement of 80 µg/day put the women at risk of exceeding the tolerable intake levels.
“The consumption of vitamin D supplements has proven to be effective in increasing vitamin D status, although this strategy is naturally only effective in those who consume the supplements. Low-dose fortification may be a strategy to increase the intake of those individuals in the lower end of the intake distribution range without increasing the risk of the upper end reaching toxic intake levels,” the researchers said….
